+ GNU Free Documentation License
+ Version 1.2, November 2002
+
+
+ Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+0. PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+1. APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The "Document", below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as "you". You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A "Secondary Section" is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called "Opaque".
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".) To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+2. VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+3. COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+4. MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+B. List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+D. Preserve all the copyright notices of the Document.
+E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+F. Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+G. Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+H. Include an unaltered copy of this License.
+I. Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+J. Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+N. Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+O. Preserve any Warranty Disclaimers.
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+5. COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+
+6. COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+8. TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+9. TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+10. FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+ Copyright (c) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+

+FLAC is an Open Source lossless audio codec developed by Josh Coalson from 2001
+to 2009.
+
+From January 2012 FLAC is being maintained by Erik de Castro Lopo under the
+auspices of the Xiph.org Foundation.
+
+FLAC is comprised of
+ * `libFLAC', a library which implements reference encoders and
+ decoders for native FLAC and Ogg FLAC, and a metadata interface
+ * `libFLAC++', a C++ object wrapper library around libFLAC
+ * `flac', a command-line program for encoding and decoding files
+ * `metaflac', a command-line program for viewing and editing FLAC
+ metadata
+ * player plugin for XMMS
+ * user and API documentation
+
+The libraries (libFLAC, libFLAC++) are
+licensed under Xiph.org's BSD-like license (see COPYING.Xiph). All other
+programs and plugins are licensed under the GNU General Public License
+(see COPYING.GPL). The documentation is licensed under the GNU Free
+Documentation License (see COPYING.FDL).

+
+ https://sourceforge.net/p/flac/support-requests/
+
+
+===============================================================================
+Prerequisites
+===============================================================================
+
+To build FLAC with support for Ogg FLAC you must have built and installed
+libogg according to the specific instructions below. You must have
+libogg 1.1.2 or greater, or there will be seeking problems with Ogg FLAC.
+
+If you are building on x86 and want the assembly optimizations, you will
+need to have NASM >= 0.98.30 installed according to the specific instructions
+below.
+
+
+===============================================================================
+Note to embedded developers
+===============================================================================
+
+libFLAC has grown larger over time as more functionality has been
+included, but much of it may be unnecessary for a particular embedded
+implementation. Unused parts may be pruned by some simple editing of
+configure.ac and src/libFLAC/Makefile.am; the following dependency
+graph shows which modules may be pruned without breaking things
+further down:
+
+metadata.h
+ stream_decoder.h
+ format.h
+
+stream_encoder.h
+ stream_decoder.h
+ format.h
+
+stream_decoder.h
+ format.h
+
+In other words, for pure decoding applications, both the stream encoder
+and metadata editing interfaces can be safely removed.
+
+There is a section dedicated to embedded use in the libFLAC API
+HTML documentation (see doc/html/api/index.html).
+
+Also, there are several places in the libFLAC code with comments marked
+with "OPT:" where a #define can be changed to enable code that might be
+faster on a specific platform. Experimenting with these can yield faster
+binaries.
+
+
+===============================================================================
+Building in a GNU environment
+===============================================================================
+
+FLAC uses autoconf and libtool for configuring and building.
+Better documentation for these will be forthcoming, but in
+general, this should work:
+
+./configure && make && make check && make install
+
+The 'make check' step is optional; omit it to skip all the tests,
+which can take several hours and use around 70-80 megs of disk space.
+Even though it will stop with an explicit message on any failure, it
+does print out a lot of stuff so you might want to capture the output
+to a file if you're having a problem. Also, don't run 'make check'
+as root because it confuses some of the tests.
+
+NOTE: Despite our best efforts it's entirely possible to have
+problems when using older versions of autoconf, automake, or
+libtool. If you have the latest versions and still can't get it
+to work, see the next section on Makefile.lite.
+
+There are a few FLAC-specific arguments you can give to
+`configure':
+
+--enable-debug : Builds everything with debug symbols and some
+extra (and more verbose) error checking.
+
+--disable-asm-optimizations : Disables the compilation of the
+assembly routines. Many routines have assembly versions for
+speed and `configure' is pretty good about knowing what is
+supported, but you can use this option to build only from the
+C sources. May be necessary for building on OS X (Intel).
+
+--enable-sse : If you are building for an x86 CPU that supports
+SSE instructions, you can enable some of the faster routines
+if your operating system also supports SSE instructions. flac
+can tell if the CPU supports the instructions but currently has
+no way to test if the OS does, so if it does, you must pass
+this argument to configure to use the SSE routines. If flac
+crashes when built with this option you will have to go back and
+configure without --enable-sse. Note that
+--disable-asm-optimizations implies --disable-sse.
+
+--enable-local-xmms-plugin : Installs the FLAC XMMS plugin in
+$HOME/.xmms/Plugins, instead of the global XMMS plugin area
+(usually /usr/lib/xmms/Input).
+
+--with-ogg=
+--with-xmms-prefix=
+--with-libiconv-prefix=
+Use these if you have these packages but configure can't find them.
+
+If you want to build completely from scratch (i.e. starting with just
+configure.ac and Makefile.am) you should be able to just run 'autogen.sh'
+but make sure and read the comments in that file first.
+
+
+===============================================================================
+Building with Makefile.lite
+===============================================================================
+
+There is a more lightweight build system for do-it-yourself-ers.
+It is also useful if configure isn't working, which may be the
+case since lately we've had some problems with different versions
+of automake and libtool. The Makefile.lite system should work
+on GNU systems with few or no adjustments.
+
+From the top level just 'make -f Makefile.lite'. You can
+specify zero or one optional target from 'release', 'debug',
+'test', or 'clean'. The default is 'release'. There is no
+'install' target but everything you need will end up in the
+obj/ directory.
+
+If you are not on an x86 system or you don't have nasm, you
+may have to change the DEFINES in src/libFLAC/Makefile.lite. If
+you don't have nasm, remove -DFLAC__HAS_NASM. If your target is
+not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN.
+
+
+===============================================================================
+Building with MSVC
+===============================================================================
+
+There are .vcproj projects and a master FLAC.sln solution to build all
+the libraries and executables with MSVC 2005 or newer.
+
+Prerequisite: you must have the Ogg libraries installed as described
+later.
+
+Prerequisite: you must have nasm installed, and nasm.exe must be in
+your PATH, or the path to nasm.exe must be added to the list of
+directories for executable files in the MSVC global options.
+
+To build everything, run Visual Studio, do File|Open and open FLAC.sln.
+From the dropdown in the toolbar, select "Release" instead of "Debug",
+then do Build|Build Solution.
+
+This will build all libraries both statically (e.g.
+objs\release\lib\libFLAC_static.lib) and as DLLs (e.g.
+objs\release\lib\libFLAC.dll), and it will build all binaries, statically
+linked (e.g. objs\release\bin\flac.exe).
+
+Everything will end up in the "objs" directory. DLLs and .exe files
+are all that are needed and can be copied to an installation area and
+added to the PATH.
+
+By default the code is configured with Ogg support. Before building FLAC
+you will need to get the Ogg source distribution
+(see http://xiph.org/downloads/), build libogg_static.lib (load
+win32\libogg_static.sln, change solution configuration to "Release" and
+code generation to "Multi-threaded (/MT)", then build), copy libogg_static.lib
+into FLAC's 'objs\release\lib' directory, and copy the entire include\ogg tree
+into FLAC's 'include' directory (so that there is an 'ogg' directory in FLAC's
+'include' directory with the files ogg.h, os_types.h and config_types.h).
+
+If you want to build without Ogg support, instead edit all .vcproj files
+and remove any "FLAC__HAS_OGG" definitions.
+
+
+===============================================================================
+Building on Mac OS X
+===============================================================================
+
+If you have Fink or a recent version of OS X with the proper autotools,
+the GNU flow above should work.
+
+
+===============================================================================
+Building with CMake
+===============================================================================
+
+CMake is a cross-platform build system. FLAC can be built on Windows, Linux, Mac
+OS X using CMake.
+
+You can use either CMake's CLI or GUI. We recommend you to have a separate build
+folder outside the repository in order to not spoil it with generated files.
+
+CLI
+---
+ Go to your build folder and run something like this:
+
+ /path/to/flac/build$ cmake /path/to/flac/source
+
+ or e.g. in Windows shell
+
+ C:\path\to\flac\build> cmake \path\to\flac\source
+ (provided that cmake is in your %PATH% variable)
+
+ That will generate build scripts for the default build system (e.g. Makefiles
+ for UNIX). After that you start build with a command like this:
+
+ /path/to/flac/build$ make
+
+ And afterwards you can run tests or install the built libraries and headers
+
+ /path/to/flac/build$ make test
+ /path/to/flac/build$ make install
+
+ If you want use a build system other than default add -G flag to cmake, e.g.:
+
+ /path/to/flac/build$ cmake /path/to/flac/source -GNinja
+ /path/to/flac/build$ ninja
+
+ or:
+
+ /path/to/flac/build$ cmake /path/to/flac/source -GXcode
+
+ Use cmake --help to see the list of available generators.
+
+ If you have OGG on your system you can tell CMake to use it:
+
+ /path/to/flac/build$ cmake /path/to/flac/source -DWITH_OGG=ON
+
+ If CMake fails to find it you can help CMake by specifying the exact path:
+
+ /path/to/flac/build$ cmake /path/to/flac/source -DWITH_OGG=ON -DOGG_ROOT=/path/to/ogg
+
+ CMake will search for OGG by default so if you don't have it you can tell
+ cmake to not do so:
+
+ /path/to/flac/build$ cmake /path/to/flac/source -DWITH_OGG=OFF
+
+ Other FLAC's options (e.g. building C++ lib or docs) can also be put to cmake
+ through -D flag.
+
+GUI
+---
+ It is likely that you would prefer to use it on Windows building for Visual
+ Studio. It's in essence the same process as building using CLI.
+
+ Open cmake-gui. In the window select a source directory (the repository's
+ root), a build directory (some other directory outside the repository). Then
+ press button "Configure". CMake will ask you which build system you prefer.
+ Choose that version of Visual Studio which you have on your system, choose
+ whether you want to build for x86 or amd64. Press OK. After CMake finishes
+ press "Generate" button, and after that "Open Project". In response CMake
+ will launch Visual Studio and open the generated solution. You can use it as
+ usual but remember that it was generated by CMake. That means that your
+ changes (e.g. some addidional compile flags) will be lost when you run CMake
+ next time.
+
+ Again, if you have OGG on your system set WITH_OGG flag in the list of
+ variables in cmake-gui window before you press "Configure".
+
+ If CMake fails to find MSVC compiler then running cmake-gui from MS Developer
+ comand prompt should help.

+ </ul>
+ New library features:

+ <li>New metadata interface to <span class="commandname">libFLAC</span> for manipulating metadata in FLAC files.</li>
+ <li>New <span class="commandname">libFLAC++</span> API, an object wrapper around <span class="commandname">libFLAC</span>.</li>

+ <a name="flac_1_0_2"><b>FLAC 1.0.2</b> (03-Dec-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ This release is only to fix a bug that was causing some of the plugins to crash sporadically. It can also affect <span class="commandname">libFLAC</span> users that reuse one file decoder instance for multiple files
+ </li>
+ </ul>
+ <br />
+
+ <a name="flac_1_0_1"><b>FLAC 1.0.1</b> (14-Nov-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ New features for users:
+ <ul>
+ <li>Support for Ogg-FLAC, i.e. <span class="commandname">flac</span> can now read and write FLAC streams using Ogg as the transport layer.</li>
+ <li>New Winamp 3 plugin based on the Wasabi Beta 1 SDK.</li>
+ <li>New utilities for adding FLAC support to the Monkey's Audio GUI (see <a href="documentation_tasks.html#monkey">how</a>).</li>
+ <li>Mac OS X support. The download area now contains an OS X binary release.</li>
+ <li>Mingw32 support.</li>
+ <li>Better handling of MS-specific 'fmt' chunks in WAVE files.</li>
+ </ul>
+ New features for developers:
+ <ul>
+ <li>Added a SeekableStreamDecoder layer between StreamDecoder and FileDecoder. This makes it easier to use libFLAC in situations where files have been abstracted away. See the latest <a href="api/index.html">documentation</a> for more. The interface for the StreamDecoder and FileDecoder remain the same and are still binary-compatible with libFLAC 1.0.</li>
+ <li>Drastically reduced the stack requirements of the encoder.</li>
+ </ul>
+ Bug fixes:
+ <ul>
+ <li>Fixed a serious bug with <span class="commandname">flac</span> and raw input where the encoder was trying to rewind when it shouldn't, which would add 12 junk samples to the encoded file. This was not present in WAVE encoding.</li>
+ <li>Fixed a minor bug in <span class="commandname">libFLAC</span> with setting the file name to stdin on a file decoder.</li>
+ <li>Fixed a minor bug in <span class="commandname">libFLAC</span> where multiple calls to setting the file name on a file decoder caused leaked memory.</li>
+ <li>Fixed a minor bug in <span class="commandname">metaflac</span>, now correctly skips an id3v2 tag if present.</li>
+ <li>Fixed a minor bug in <span class="commandname">metaflac</span>, now correctly skips long metadata blocks.</li>
+ </ul>

+
+ <a name="flac_1_0"><b>FLAC 1.0</b> (20-Jul-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ It's finally here. There are a few new features but mostly it is minor bug fixes since 0.10:
+ <ul>
+ <li>New '--sector-align' option to <span class="commandname">flac</span> which aligns a group of encoded files on CD audio sector boundaries.</li>
+ <li>New '--output-prefix' option to <span class="commandname">flac</span> to allow the user to prepend a prefix to all output filenames (useful, for example, for encoding/decoding to a different directory).</li>
+ <li>Better WAVE autodetection (doesn't rely on ungetc() anymore).</li>
+ <li>Cleaner one-line encoding/decoding stats.</li>
+ <li>Changes to the libFLAC interface and type names to make binary compatibility easier to maintain in the future.</li>
+ <li>New '--sse-os' option to 'configure' to enable faster SSE-based routines.</li>
+ <li>Another (hopefully last) fix to the Winamp 2 plugin.</li>
+ <li>Slightly improved Rice parameter estimation.</li>
+ <li>Bug fixes for some very rare corner cases when encoding.</li>
+ </ul>
+ </li>
+ </ul>
+ <br />
+
+ <a name="flac_0_10"><b>FLAC 0.10</b> (07-Jun-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ This is probably the final beta. There have been many improvements in the last two months:
+ <ul>
+ <li>Both the encoder and decoder have been significantly sped up. Aside from C improvements, the code base now has an assembly infrastructure that allows assembly routines for different architectures to be easily integrated. Many key routines have now have faster IA-32 implementations (thanks to Miroslav).</li>
+ <li>A new metadata block <a href="format.html#def_SEEKTABLE">SEEKTABLE</a> has been defined to hold an arbitrary number of seek points, which speeds up seeking within a stream.</li>
+ <li><span class="commandname">flac</span> now has a command-line usage similar to 'gzip'; make sure to see the latest <a href="documentation.html">documentation</a> for the new usage. It also attempts to preserve the input file's timestamp and permissions.</li>
+ <li>The -# options in <span class="commandname">flac</span> have been tweaked to yield the best compression-to-encode-time ratios. The new default is -5.</li>
+ <li><span class="commandname">flac</span> can now usually autodetect WAVE files when encoding so that -fw is usually not needed when encoding from stdin.</li>
+ <li>The WAVE reader in <span class="commandname">flac</span> now just ignores (with a warning) unsupported sub-chunks instead of aborting with an error.</li>
+ <li>Added an option '--delete-input-file' to <span class="commandname">flac</span> which automatically deletes the input after a successful encode/decode.</li>
+ <li>Added an option '-o' to <span class="commandname">flac</span> to force the output file name (the old usage of "flac - outputfilename" is no longer supported).</li>
+ <li>Changed the XMMS plugin to send smaller chunks of samples (now 512) so that visualization is not slow.</li>
+ <li>Fixed a bug in the stream decoder where the decoded samples counter got corrupted after a seek.</li>
+ </ul>
+
+ </li>
+ </ul>
+ <br />
+
+ <a name="flac_0_9"><b>FLAC 0.9</b> (31-Mar-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ Bug fixes and some new features:
+ <ul>
+ <li>FLAC's sync code has been lengthened to 14 bits from 9 bits. This should enable a faster and more robust synchronization mechanism.</li>
+ <li>Two reserved bits were added to the frame header.</li>
+ <li>A CRC-16 was added to the FLAC frame footer, and the decoder now does frame integrity checking based on the CRC.</li>
+ <li>The format now includes a new subframe field to indicate when a subblock has one or more 0 LSBs for all samples. This increases compression on some kinds of data.</li>
+ <li>Added two options to the analysis mode, one for including the residual signal in the analysis file, and one for generating gnuplot files of each subframe's residual distribution with some statistics. See the latest <a href="documentation.html#analysis_options">documentation</a>.</li>
+ <li>XMMS plugin now supports 8-bit files.</li>
+ <li>Fixed a bug in the Winamp2 plugin where the audio sounded garbled.</li>
+ <li>Fixed a bug in the Winamp2 plugin where Winamp would hang sporadically at the end of a track (c.f. <a href="http://sourceforge.net/projects/flac/&atid=113478">bug #231197</a>).</li>
+ </ul>
+
+ </li>
+ </ul>
+
+ <br />
+
+ <a name="flac_0_8"><b>FLAC 0.8</b> (05-Mar-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ Changes since 0.7:
+ <ul>
+ <li>Created a new utility called <span class="commandname">metaflac</span>. It is a metadata editor for .flac files. Right now it just lists the contents of the metadata blocks but eventually it will allow update/insertion/deletion.</li>
+ <li>Added two new metadata blocks: PADDING which has an obvious function, and APPLICATION, which is meant to be open to third party applications. See the <a href="format.html#def_APPLICATION">latest format docs</a> for more info, or the new <a href="id.html">id registration page</a>.</li>
+ <li>Added a <span class="argument">-P</span> option to <span class="commandname">flac</span> to reserve a PADDING block when encoding.</li>
+ <li>Added support for 24-bit files to <span class="commandname">flac</span> (the FLAC format always supported it).</li>
+ <li>Started the Winamp3 plugin.</li>
+ <li>Greatly expanded the test suite, adding more streams (24-bit streams, noise streams, non-audio streams, more patterns) and more option combinations to the encoder. The test suite runs about 30 streams and over 5000 encodings now.</li>
+ <li>Fixed a bug in <span class="commandname">libFLAC</span> that happened when using an exhaustive LPC coefficient quantization search with 8 bps input.</li>
+ <li>Fixed a bug in <span class="commandname">libFLAC</span> where the error estimation in the fixed predictor could overflow.</li>
+ <li>Fixed a bug in <span class="commandname">libFLAC</span> where LPC was attempted even when the autocorrelation coefficients implied it wouldn't help.</li>
+ <li>Reworked the LPC coefficient quantizer, which also fixed another bug that might occur in rare cases.</li>
+ <li>Really fixed the '-V overflow' bug (c.f. <a href="http://sourceforge.net/p/flac/bugs/5/">bug #231976</a>).</li>
+ <li>Fixed a bug in <span class="commandname">flac</span> related to the decode buffer sizing.</li>
+ </ul>
+ FLAC is very close to being ready for an official release. The only known problems left are with the Winamp plugins, which should be fixed soon, and pipes with MSVC.
+ </li>
+ </ul>
+ <br />
+
+ <a name="flac_0_7"><b>FLAC 0.7</b> (12-Feb-2001)</a>
+
+ <br />
+
+ <ul>
+ <li>
+ Changes:
+ <ul>
+ <li>Fixed a bug that happened when both -fr and --seek were used at the same time.</li>
+ <li>Fixed a bug with -p (c.f. <a href="http://sourceforge.net/p/flac/bugs/1/">bug #230992</a>).</li>
+ <li>Fixed a bug that happened when using large (>32K) blocksizes and -V (c.f. <a href="http://sourceforge.net/p/flac/bugs/5/">bug #231976</a>).</li>
+ <li>Fixed a bug where encoder was double-closing a file.</li>
+ <li>Expanded the test suite.</li>
+ <li>Added more optimization flags for gcc, which should speed up flac.</li>
+ </ul>
+ </li>
+ </ul>
+ <br />
+
+ <a name="flac_0_6"><b>FLAC 0.6</b> (28-Jan-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ The encoder is now much faster. The -m option has been sped up by 4x and -r improved, meaning that in the default compression mode (-6), encoding should be at least 3 times faster. Other changes:
+ <ul>
+ <li>Some bugs related to <span class="commandname">flac</span> and pipes were fixed</li>
+ <li>A "loose mid-side" (<span class="argument">-M</span>) option to the encoder has been added, which adaptively switches between independent and mid-side coding, instead of the exhaustive search that <span class="argument">-m</span> does.</li>
+ <li>An analyze mode (<span class="argument">-a</span>) has been added to <span class="commandname">flac</span>. This is useful mainly for developers; currently it will dump info about each frame and subframe to a file. It's a text file in a format that can be easily processed by scripts; a separate analysis program is in the works.</li>
+ <li>The source now has an autoconf/libtool-based build system. This should allow the source to build "out-of-the-box" on many more platforms.</li>
+ </ul>
+ </li>
+ </ul>
+ <br />
+
+ <a name="flac_0_5"><b>FLAC 0.5</b> (15-Jan-2001)</a>
+
+ <br />
+ <ul>
+ <li>
+ This is the first beta version of FLAC. Being beta, there will be no changes to the format that will break older streams, unless a serious bug involving the format is found. What this means is that, barring such a bug, streams created with 0.5 will be decodable by future versions. This version also includes some new features:
+ <ul>
+ <li>An <a href="http://userpages.umbc.edu/~mabzug1/cs/md5/md5.html">MD5 signature</a> of the unencoded audio is computed during encoding, and stored in the Encoding metadata block in the stream header. When decoding, <span class="commandname">flac</span> will now compute the MD5 signature of the decoded data and compare it against the signature in the stream header.</li>
+ <li>A test mode (<span class="argument">-t</span>) has been added to <span class="commandname">flac</span>. It works like decode mode but doesn't write an output file.</li>
+ </ul>
+ </li>
+ </ul>
+ <br />
+
+ <a name="flac_0_4"><b>FLAC 0.4</b> (23-Dec-2000)</a>
+
+ <br />
+ <ul>
+ <li>This version fixes a bug in the constant subframe detection. More importantly, a verify option (-V) has been added to <span class="commandname">flac</span> that verifies the encoding process. With this option turned on, <span class="commandname">flac</span> will create a parallel decoder while encoding to make sure that the encoded output decodes to exactly match the original input. In this way, any unknown bug in the encoder will be caught and <span class="commandname">flac</span> will abort with an error message.</li>

+ goals

+ <div class="box_body">
+ Since FLAC is an open-source project, it's important to have a set of goals that everyone works to. They may change slightly from time to time but they're a good guideline. Changes should be in line with the goals and should not attempt to embrace any of the anti-goals.<br />
+ <br />
+ <b>Goals</b>
+ <ul>
+ <li>
+ FLAC should be and stay an open format with an open-source reference implementation.
+ </li>
+ <li>
+ FLAC should be lossless. This seems obvious but lossy compression seems to creep into every audio codec. This goal also means that <span class="commandname">flac</span> should stay archival quality and be truly lossless for all input. Testing of releases should be thorough.
+ </li>
+ <li>
+ FLAC should yield respectable compression, on par or better than other lossless codecs.
+ </li>
+ <li>
+ FLAC should allow at least realtime decoding on even modest hardware.
+ </li>
+ <li>
+ FLAC should support fast sample-accurate seeking.
+ </li>
+ <li>
+ FLAC should allow gapless playback of consecutive streams. This follows from the lossless goal.
+ </li>
+ <li>
+ The FLAC project owes a lot to the many people who have advanced the audio compression field so freely, and aims also to contribute through the open-source development of new ideas.
+ </li>
+ </ul>
+ <b>Anti-goals</b><br />
+ <ul>
+ <li>
+ Lossy compression. There are already many suitable lossy formats (<a href="http://www.xiph.org/vorbis/">Ogg Vorbis</a>, <a href="http://www.mp3-tech.org/">MP3</a>, etc.).
+ </li>
+ <li>
+ Copy prevention, DRM, etc. There is no intention to add any copy prevention methods. Of course, we can't stop someone from encrypting a FLAC stream in another container (e.g. the way Apple encrypts AAC in MP4 with FairPlay), that is the choice of the user.

+ <div class="box_body">
+ The basic structure of a FLAC stream is:
+ <ul>
+ <li>The four byte string "<span class="code">fLaC</span>"</li>
+ <li>The <a href="format.html#def_STREAMINFO"><span class="code">STREAMINFO</span></a> metadata block</li>
+ <li>Zero or more other metadata blocks</li>
+ <li>One or more audio frames</li>
+ </ul>
+ The first four bytes are to identify the FLAC stream. The metadata that follows contains all the information about the stream except for the audio data itself. After the metadata comes the encoded audio data.<br />
+ <br />
+ <b>METADATA</b><br />
+ <br />
+ FLAC defines several types of metadata blocks (see the <a href="format.html">format</a> page for the complete list). Metadata blocks can be any length and new ones can be defined. A decoder is allowed to skip any metadata types it does not understand. Only one is mandatory: the <span class="code">STREAMINFO</span> block. This block has information like the sample rate, number of channels, etc., and data that can help the decoder manage its buffers, like the minimum and maximum data rate and minimum and maximum block size. Also included in the <span class="code">STREAMINFO</span> block is the MD5 signature of the <i>unencoded</i> audio data. This is useful for checking an entire stream for transmission errors.<br />
+ <br />
+ Other blocks allow for padding, seek tables, tags, cuesheets, and application-specific data. There are <a href="documentation_tools_flac.html"><span class="commandname">flac</span> options</a> for adding <span class="code">PADDING</span> blocks or specifying seek points. FLAC does not require seek points for seeking but they can speed up seeks, or be used for cueing in editing applications.<br />
+ <br />
+ Also, if you have a need of a custom metadata block, you can define your own and request an ID <a href="id.html">here</a>. Then you can reserve a <span class="code">PADDING</span> block of the correct size when encoding, and overwrite the padding block with your <span class="code">APPLICATION</span> block after encoding. The resulting stream will be FLAC compatible; decoders that are aware of your metadata can use it and the rest will safely ignore it.<br />
+ <br />
+ <b>AUDIO DATA</b><br />
+ <br />
+ After the metadata comes the encoded audio data. Audio data and metadata are not interleaved. Like most audio codecs, FLAC splits the unencoded audio data into blocks, and encodes each block separately. The encoded block is packed into a frame and appended to the stream. The reference encoder uses a single block size for the whole stream but the FLAC format does not require it.<br />
+ <br />
+ <b>BLOCKING</b><br />
+ <br />
+ The block size is an important parameter to encoding. If it is too small, the frame overhead will lower the compression. If it is too large, the modeling stage of the compressor will not be able to generate an efficient model. Understanding FLAC's modeling will help you to improve compression for some kinds of input by varying the block size. In the most general case, using linear prediction on 44.1kHz audio, the optimal block size will be between 2-6 ksamples. <span class="commandname">flac</span> defaults to a block size of 4096 in this case. Using the fast fixed predictors, a smaller block size is usually preferable because of the smaller frame header.<br />
+ <br />
+ <b>INTER-CHANNEL DECORRELATION</b><br />
+ <br />
+ In the case of stereo input, once the data is blocked it is optionally passed through an inter-channel decorrelation stage. The left and right channels are converted to center and side channels through the following transformation: mid = (left + right) / 2, side = left - right. This is a lossless process, unlike joint stereo. For normal CD audio this can result in significant extra compression. <span class="commandname">flac</span> has two options for this: <span class="argument">-m</span> always compresses both the left-right and mid-side versions of the block and takes the smallest frame, and <span class="argument">-M</span>, which adaptively switches between left-right and mid-side.<br />
+ <br />
+ <b>MODELING</b><br />
+ <br />
+ In the next stage, the encoder tries to approximate the signal with a function in such a way that when the approximation is subtracted, the result (called the <i>residual</i>, <i>residue</i>, or <i>error</i>) requires fewer bits-per-sample to encode. The function's parameters also have to be transmitted so they should not be so complex as to eat up the savings. FLAC has two methods of forming approximations: 1) fitting a simple polynomial to the signal; and 2) general linear predictive coding (LPC). I will not go into the details here, only some generalities that involve the encoding options.<br />
+ <br />
+ First, fixed polynomial prediction (specified with <span class="argument">-l 0</span>) is much faster, but less accurate than LPC. The higher the maximum LPC order, the slower, but more accurate, the model will be. However, there are diminishing returns with increasing orders. Also, at some point (usually around order 9) the part of the encoder that guesses what is the best order to use will start to get it wrong and the compression will actually decrease slightly; at that point you will have to you will have to use the exhaustive search option <span class="argument">-e</span> to overcome this, which is significantly slower.<br />
+ <br />
+ Second, the parameters for the fixed predictors can be transmitted in 3 bits whereas the parameters for the LPC model depend on the bits-per-sample and LPC order. This means the frame header length varies depending on the method and order you choose and can affect the optimal block size.<br />
+ <br />
+ <b>RESIDUAL CODING</b><br />
+ <br />
+ Once the model is generated, the encoder subracts the approximation from the original signal to get the residual (error) signal. The error signal is then losslessly coded. To do this, FLAC takes advantage of the fact that the error signal generally has a Laplacian (two-sided geometric) distribution, and that there are a set of special Huffman codes called Rice codes that can be used to efficiently encode these kind of signals quickly and without needing a dictionary.<br />
+ <br />
+ Rice coding involves finding a single parameter that matches a signal's distribution, then using that parameter to generate the codes. As the distribution changes, the optimal parameter changes, so FLAC supports a method that allows the parameter to change as needed. The residual can be broken into several <i>contexts</i> or <i>partitions</i>, each with it's own Rice parameter. <span class="commandname">flac</span> allows you to specify how the partitioning is done with the <span class="argument">-r</span> option. The residual can be broken into 2^<i>n</i> partitions, by using the option <span class="argument">-r n,n</span>. The parameter <i>n</i> is called the <i>partition order</i>. Furthermore, the encoder can be made to search through <i>m</i> to <i>n</i> partition orders, taking the best one, by specifying <span class="argument">-r m,n</span>. Generally, the choice of n does not affect encoding speed but m,n does. The larger the difference between m and n, the more time it will take the encoder to search for the best order. The block size will also affect the optimal order.<br />
+ <br />
+ <b>FRAMING</b><br />
+ <br />
+ An audio frame is preceded by a frame header and trailed by a frame footer. The header starts with a sync code, and contains the minimum information necessary for a decoder to play the stream, like sample rate, bits per sample, etc. It also contains the block or sample number and an 8-bit CRC of the frame header. The sync code, frame header CRC, and block/sample number allow resynchronization and seeking even in the absence of seek points. The frame footer contains a 16-bit CRC of the entire encoded frame for error detection. If the reference decoder detects a CRC error it will generate a silent block.<br />
+ <br />
+ <b>MISCELLANEOUS</b><br />
+ <br />
+ As a convenience, the reference decoder knows how to skip <a href="http://www.id3.org/">ID3v1 and ID3v2 tags</a>. Note however that the FLAC specification does not require compliant implementations to support ID3 in any form and their use is strongly discouraged.<br />
+ <br />
+ <span class="commandname">flac</span> has a verify option <span class="argument">-V</span> that verifies the output while encoding. With this option, a decoder is run in parallel to the encoder and its output is compared against the original input. If a difference is found <span class="commandname">flac</span> will stop with an error.

+ <br />
+ <span class="commandname">flac</span> assumes that files ending in ".wav" or that have the RIFF WAVE header present are WAVE files, files ending in ".w64" or have the Wave64 header present are Wave64 files, files ending in ".rf64" or have the RF64 header present are RF64 files, files ending in ".aif" or ".aiff" or have the AIFF header present are AIFF files, and files ending in ".flac" or have the FLAC header present are FLAC files. This assumption may be overridden with a command-line option. It also assumes that files ending in ".oga" or ".ogg" or have the Ogg FLAC header present are Ogg FLAC files. Other than this, <span class="commandname">flac</span> makes no assumptions about file extensions, though the convention is that FLAC files have the extension ".flac" (or ".fla" on ancient "8.3" file systems like FAT-16).<br />
+ <br />
+ Before going into the full command-line description, a few other things help to sort it out: 1) <span class="commandname">flac</span> encodes by default, so you must use <b>-d</b> to decode; 2) the options <span class="argument">-0</span> .. <span class="argument">-8</span> (or <span class="argument">--fast</span> and <span class="argument">--best</span>) that control the compression level actually are just synonyms for different groups of specific encoding options (described later) and you can get the same effect by using the same options; 3) <span class="commandname">flac</span> behaves similarly to gzip in the way it handles input and output files.<br />
+ <br />
+ Skip to the <a href="#tutorial">tutorial</a> below for examples of some common tasks.<br />
+ <br />
+ <span class="commandname">flac</span> will be invoked one of four ways, depending on whether you are encoding, decoding, testing, or analyzing:
+ <ul>
+ <li>
+ Encoding: flac [<i><a href="#general_options"><general-options></a></i>] [<i><a href="#format_options"><format-options></a></i>] [<i><a href="#encoding_options"><encoding options></a></i>] [inputfile [...]]
+ </li>
+ <li>
+ Decoding: flac -d [<i><a href="#general_options"><general-options></a></i>] [<i><a href="#format_options"><format-options></a></i>] [<i><a href="#decoding_options"><decoding options></a></i>] [FLACfile [...]]
+ </li>
+ <li>
+ Testing: flac -t [<i><a href="#general_options"><general-options></a></i>] [FLACfile [...]]
+ </li>
+ <li>
+ Analyzing: flac -a [<i><a href="#general_options"><general-options></a></i>] [<i><a href="#analysis_options"><analysis-options></a></i>] [FLACfile [...]]
+ </li>
+ </ul>
+ In any case, if no <span class="argument">inputfile</span> is specified, stdin is assumed. If only one inputfile is specified, it may be "-" for stdin. When stdin is used as input, <span class="commandname">flac</span> will write to stdout. Otherwise <span class="commandname">flac</span> will perform the desired operation on each input file to similarly named output files (meaning for encoding, the extension will be replaced with ".flac", or appended with ".flac" if the input file has no extension, and for decoding, the extension will be ".wav" for WAVE output and ".raw" for raw output). The original file is not deleted unless --delete-input-file is specified.<br />
+ <br />
+ If you are encoding/decoding from stdin to a file, you should use the -o option like so:
+ <ul>
+ <li>
+ flac [options] -o outputfile
+ </li>
+ <li>
+ flac -d [options] -o outputfile
+ </li>
+ </ul>
+ which are better than:
+ <ul>
+ <li>
+ flac [options] > outputfile
+ </li>
+ <li>
+ flac -d [options] > outputfile
+ </li>
+ </ul>
+ since the former allows flac to seek backwards to write the <span class="code">STREAMINFO</span> or RIFF WAVE header contents when necessary.<br />
+ <br />
+ Also, you can force output data to go to stdout using <span class="argument">-c</span>.<br />
+ <br />
+ To encode or decode files that start with a dash, use <span class="argument">--</span> to signal the end of options, to keep the filenames themselves from being treated as options:
+ <ul>
+ <li>
+ <span class="code">flac -V -- -01-filename.wav</span>
+ </li>
+ </ul>
+ The encoding options affect the compression ratio and encoding speed. The format options are used to tell <span class="commandname">flac</span> the arrangement of samples if the input file (or output file when decoding) is a raw file. If it is a RIFF WAVE, Wave64, RF64, or AIFF file the format options are not needed since they are read from the file's header.<br />
+ <br />
+ In test mode, <span class="commandname">flac</span> acts just like in decode mode, except no output file is written. Both decode and test modes detect errors in the stream, but they also detect when the MD5 signature of the decoded audio does not match the stored MD5 signature, even when the bitstream is valid.<br />
+ <br />
+ <span class="commandname">flac</span> can also re-encode FLAC files. In other words, you can specify a FLAC or Ogg FLAC file as an input to the encoder and it will decoder it and re-encode it according to the options you specify. It will also preserve all the metadata unless you override it with other options (e.g. specifying new tags, seekpoints, cuesheet, padding, etc.).<br />
+ <br />
+ <span class="commandname">flac</span> has been tuned so that the default settings yield a good speed vs. compression tradeoff for many kinds of input. However, if you are looking to maximize the compression rate or speed, or want to use the full power of FLAC's metadata system, see <a href="documentation_format_overview.html">About the FLAC Format</a>.<br />

+ This one's a little tricky: notice that <span class="commandname">flac</span> is in encode mode by default (you have to specify <span class="argument">-d</span> to decode) so this command actually recompresses <tt>abc.flac</tt> back to <tt>abc.flac</tt>. <span class="argument"><a href="#flac_options_force">--force</a></span> is needed to make sure you really want to overwrite <tt>abc.flac</tt> with a new version.

+ The <span class="argument"><specification></span> is a shorthand notation for describing how to apply ReplayGain. All components are optional but order is important. '<span class="argument">[]</span>' means 'optional'. '<span class="argument">|</span>' means 'or'. '<span class="argument">{}</span>' means required. The format is:<br />

+ <li>
+ <span class="argument"><preamp></span><br />
+ A floating point number in dB. This is added to the existing gain value.
+ </li>
+ <li>
+ <span class="argument">a|t</span><br />
+ Specify '<span class="argument">a</span>' to use the album gain, or '<span class="argument">t</span>' to use the track gain. If tags for the preferred kind (album/track) do not exist but tags for the other (track/album) do, those will be used instead.
+ </li>
+ <li>
+ <span class="argument">l|L</span><br />
+ Specify '<span class="argument">l</span>' to peak-limit the output, so that the ReplayGain peak value is full-scale. Specify '<span class="argument">L</span>' to use a 6dB hard limiter that kicks in when the signal approaches full-scale.
+ </li>
+ <li>
+ <span class="argument">n{0|1|2|3}</span><br />
+ Specify the amount of noise shaping. ReplayGain synthesis happens in floating point; the result is dithered before converting back to integer. This quantization adds noise. Noise shaping tries to move the noise where you won't hear it as much. <span class="argument">0</span> means no noise shaping, <span class="argument">1</span> means 'low', <span class="argument">2</span> means 'medium', <span class="argument">3</span> means 'high'.
+ </li>
+ </ul>
+ For example, the default of <span class="argument">0aLn1</span> means 0dB preamp, use album gain, 6dB hard limit, low noise shaping.<br />
+ <br />
+ <span class="argument">--apply-replaygain-which-is-not-lossless=3</span> means 3dB preamp, use album gain, no limiting, no noise shaping.<br />
+ <br />
+ <span class="commandname">flac</span> uses the ReplayGain tags for the calculation. If a stream does not have the required tags or they can't be parsed, decoding will continue with a warning, and no ReplayGain is applied to that stream.

+ Window audio data with given the apodization function. The functions are: bartlett, bartlett_hann, blackman, blackman_harris_4term_92db, connes, flattop, gauss(STDDEV), hamming, hann, kaiser_bessel, nuttall, rectangle, triangle, tukey(P), partial_tukey(n[/ov[/P]]), punchout_tukey(n[/ov[/P]]), welch.<br />
+ For gauss(STDDEV), STDDEV is the standard deviation (0<STDDEV<=0.5).<br />
+ For tukey(P), P specifies the fraction of the window that is tapered (0<=P<=1; P=0 corresponds to "rectangle" and P=1 corresponds to "hann").<br />
+ For partial_tukey(n) and punchout_tukey(n), n apodization functions are added that span different parts of each block. Values of 2 to 6 seem to yield sane results. If necessary, an overlap can be specified, as can be the taper parameter, for example partial_tukey(2/0.2) or partial_tukey(2/0.2/0.5). ov should be smaller than 1 and can be negative.<br />
+ Please note that P, STDDEV and ov are locale specific, so a comma as decimal separator might be required instead of a dot.<br />
+ More than one -A option (up to 32) may be used. Any function that is specified erroneously is silently dropped. The encoder chooses suitable defaults in the absence of any -A options; any -A option specified replaces the default(s).<br />
+ When more than one function is specified, then for every subframe the encoder will try each of them separately and choose the window that results in the smallest compressed subframe. Multiple functions can greatly increase the encoding time.<br />

+ Set the [min,]max residual partition order. The min value defaults to 0 if unspecified.<br />
+ <br />
+ By default the encoder uses a single Rice parameter for the subframe's entire residual. With this option, the residual is iteratively partitioned into 2^min# .. 2^max# pieces, each with its own Rice parameter. Higher values of max# yield diminishing returns. The most bang for the buck is usually with <span class="argument">-r 2,2</span> (more for higher block sizes). This usually shaves off about 1.5%. The technique tends to peak out about when blocksize/(2^n)=128. Use <span class="argument">-r 0,15</span> to force the highest degree of optimization.

+ <span class="commandname">metaflac</span> is the command-line <span class="code">.flac</span> file metadata editor. You can use it to list the contents of metadata blocks, edit, delete or insert blocks, and manage padding.<br />
+ <br />
+ <span class="commandname">metaflac</span> takes a set of "options" (though some are not optional) and a set of FLAC files to operate on. There are three kinds of "options":
+ <ul>
+ <li>
+ Major operations, which specify a mode of operation like listing blocks, removing blocks, etc. These will have sub-operations describing exactly what is to be done.
+ </li>
+ <li>
+ Shorthand operations, which are convenient synonyms for major operations. For example, there is a shorthand operation <span class="argument">--show-sample-rate</span> that shows just the sample rate field from the <span class="code">STREAMINFO</span> metadata block.
+ </li>
+ <li>
+ Global options, which affect all the operations.
+ </li>
+ </ul>
+ All of these are described in the tables below. At least one shorthand or major operation must be supplied. You can use multiple shorthand operations to do more than one thing to a file or set of files. Most of the common things to do to metadata have shorthand operations. As an example, here is how to show the MD5 signatures for a set of three FLAC files:<br />
+ <br />
+ <span class="code">metaflac --show-md5sum file1.flac file2.flac file3.flac</span><br />
+ <br />
+ Another example; this removes all DESCRIPTION and COMMENT tags in a set of FLAC files, and uses the <span class="argument">--preserve-modtime</span> global option to keep the FLAC file modification times the same (usually when files are edited the modification time is set to the current time):<br />
+ <br />
+ <span class="code">metaflac --preserve-modtime --remove-tag=DESCRIPTION --remove-tag=COMMENT file1.flac file2.flac file3.flac</span><br />

+ <a name="general__what_is"><b>What is FLAC?</b></a><br />
+ <br />
+ FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see <a href="http://xiph.org/flac/links.html#hardware">supported devices</a>) just like you would an MP3 file.<br />
+ <br />
+ For more details, see <a href="features.html">What is FLAC?</a><br />
+ <br />
+ <a name="general__how_to"><b>I have a FLAC file, how do I play it?</b></a><br />
+ <b>How can I create FLAC files?</b><br />
+ <br />
+ See <a href="http://xiph.org/flac/documentation_tasks.html">Using FLAC</a> or a <a href="http://xiph.org/flac/links.html">list of hardware that supports FLAC</a>.<br />
+ <br />
+ <a name="general__license"><b>What licensing applies to the FLAC format and software?</b></a><br />
+ <br />
+ See the <a href="license.html">license page</a>.<br />
+ <br />
+ <a name="general__tagging"><b>What kinds of tags does FLAC support?</b></a><br />
+ <br />
+ FLAC has it's own native tagging system which is identical to that of Vorbis. They are called alternately "FLAC tags" and "Vorbis comments". It is the only tagging system required and guaranteed to be supported by FLAC implementations.<br />
+ <br />
+ Out of convenience, the reference decoder knows how to skip ID3 tags so that they don't interfere with decoding. But you should not expect any tags beside FLAC tags to be supported in applications; some implementations may not even be able to decode a FLAC file with ID3 tags.<br />
+ <br />
+ <a name="general__software"><b>What software support FLAC?</b></a><br />
+ <br />
+ This list is so large now it is difficult to maintain and keep up-to-date. For a partial list of open-source software that supports FLAC, see the <a href="http://xiph.org/flac/links.html#software">software section</a> of the links page. For a partial list of the most popular software used to encode, decode, play, tag, and rip FLAC files, see the <a href="http://xiph.org/flac/download.html">download page</a>.<br />
+ <br />
+ <a name="general__software_wmp"><b>How can I play FLAC in Windows Media Player?</b></a><br />
+ <br />
+ The easiest way is to use the Xiph.org Directshow Filters, <a href="http://www.xiph.org/dshow/downloads/">download them here</a><br />
+ <br />
+ <a name="general__hardware"><b>What hardware products support FLAC?</b></a><br />
+ <br />
+ See the <a href="http://xiph.org/flac/links.html#hardware">hardware section</a> of the links page.<br />
+ <br />
+ <a name="general__native_vs_ogg"><b>What is the difference between (native) FLAC and Ogg FLAC?</b></a><br />
+ <br />
+ You can think of an audio codec as having two layers. The inside layer is the raw compressed data, and the outside layer is the "container" or "transport layer" that splits and arranges the compressed data in pieces so it can be seeked through, edited, etc.<br />
+ <br />
+ "Native" FLAC is the compressed FLAC data stored in a very minimalist container, designed to be very efficient at storing single audio streams.<br />
+ <br />
+ Ogg FLAC is the compressed FLAC data stored in an <a href="http://xiph.org/vorbis/doc/oggstream.html">Ogg container</a>. Ogg is a much more powerful transport layer that enables mixing several kinds of different streams (audio, data, metadata, etc). The overhead is slightly higher than with native FLAC.<br />
+ <br />
+ In either case, the compressed FLAC data is the same and one can be converted to the other without re-encoding.<br />
+ <br />
+ <a name="general__native_or_ogg"><b>Which should I use, (native) FLAC or Ogg FLAC?</b></a><br />
+ <br />
+ The short answer right now is probably "native FLAC". If all you are doing is compressing audio to be played back later, native FLAC will do everything you need, is more widely supported, and will yield smaller files. If you plan to edit the compressed audio, or want to multiplex the audio with video later in an Ogg container, Ogg FLAC is a better choice.<br />
+ <br />
+ <a name="general__no_cuesheet_tags"><b>Why aren't PERFORMER/TITLE/etc tags stored in the FLAC CUESHEET block?</b></a><br />
+ <br />
+ This has turned out to be a pretty polarizing issue and requires a long explanation.<br />
+ <br />
+ The original purpose of a cue sheet in CD authoring software was to lay out the disc, essentially specifying how the audio will be organized on the disc; some of the information ends up as the CD table of contents: the track numbers and locations, and the index points. Later CD-TEXT was added. But CD-TEXT is a very complex spec, and actually goes in the CD subcode data. It is internationalized, not through Unicode, but with several different character sets, some of them multi-byte. It even allows for graphics. In cue sheets, the TITLE/PERFORMER/etc tags are just a limited shorthand for authoring CD-TEXT, but when you rip, you almost never parse the CD-TEXT, you get it from another database, and it doesn't really belong in the FLAC CUESHEET block.<br />
+ <br />
+ For FLAC the intention is that applications can calculate the CDDB or CDindex ID from the CUESHEET block and look it up in an online or local database just like CD rippers and players do. But if you really want it in the file itself, the track metadata should be stored separate from the CUESHEET, and already can be because of FLAC's metadata system. There just isn't a method specified yet because as soon as it is, people will say that it's not flexible enough. From experience (and you can see this come up time and time again in many lists), anyone who is going to the trouble of keeping a lossless collection in the first place will already be picky about metadata, and it is hard to come up with a standard that will please even the majority. That is the big problem with metadata and is why Xiph has deferred on it, waiting for someone to come up with a good metadata spec that can be multiplexed together with data.<br />
+ <br />
+ Some players (for example Foobar2000) allow you to store the CDDB data as FLAC tags and can parse that.<br />
+ <br />
+ <a name="general__no_wave_metadata"><b>Why doesn't FLAC store all WAVE metadata?</b></a><br />
+ <a name="general__not_wave_compressor"><b>If flac compresses WAVE files, why isn't it technically a WAVE file compressor?</b></a><br />
+ <br />
+ (By default, <span class="commandname">flac</span> does not store WAVE metadata, but it can with the <span class="argument"><a href="documentation_tools_flac.html#flac_options_keep_foreign_metadata">--keep-foreign-metadata</a></span> option described below.)<br />
+ <br />
+ FLAC is a general-purpose audio format, not just a compressed WAVE file format. There's a subtle difference. WAVE is a complicated standard; many kinds of data besides audio data can be put in it. FLAC's purpose is not to reproduce a WAVE file, including all the non-audio data that is in it, it is to losslessly compress the audio.<br />
+ <br />
+ However, if you really need to store the non-audio parts of a WAVE or AIFF file, you can use the <span class="argument"><a href="documentation_tools_flac.html#flac_options_keep_foreign_metadata">--keep-foreign-metadata</a></span> option to <span class="commandname">flac</span> when encoding to store it in FLAC metadata, then use the option again when decoding to restore in to the decoded WAVE/AIFF file.<br />
+ <br />
+ <a name="general__no_riff_subchunks"><b>Why do some lossless comparisons say FLAC does not support RIFF chunks?</b></a><br />
+ <br />
+ This is a limitation that no longer exists with FLAC (<a href="faq.html#general__no_wave_metadata">see above</a>).<br />
+ <br />
+ <a name="general__asymmetry"><b>Why do the encoder settings have a big effect on the encoding time but not the decoding time?</b></a><br />
+ <br />
+ It's hard to explain without going into the codec design, but to oversimplify, the encoder is looking for functions that approximate the signal. Higher settings make the encoder search more to find better approximations. The functions are themselves encoded in the FLAC file. Decoding only requires computing the one chosen function, and the complexity of the function is very stable. This is by design, to make decoding easier, and is one of the things that makes FLAC easy to implement in hardware.<br />
+ <br />
+ <a name="general__alternatives"><b>Why use FLAC instead of other codecs that compress more?</b></a><br />
+ <br />
+ For most users, a small difference in filesize is usually far outweighed by FLAC's advantages: open patent free codec, portable open source (BSD) reference implementation, documented API, multi-platform support, hardware support, multi-channel support, etc. Improving FLAC to get a little more compression is not worth making it more complex and more compute-intensive to decode, and hence, less likely to be supported in hardware.<br />
+ <br />
+ <a name="general__encode_faster"><b>Why can't you make FLAC encode faster?</b></a><br />
+ <br />
+ FLAC already encodes pretty fast. It is faster than real-time even on weak systems and is not much slower than even the fastest codecs. And it is faster than the CD ripping process with which it is usually paired, meaning even if it went faster, it would not speed up the ripping-encoding process anyway.<br />
+ <br />
+ Part of the reason is that FLAC is asymmetric <a href="faq.html#general__asymmetry">(see also)</a>. That means that it is optimized for decoding speed at the expense of encoding speed, because it makes it easier to decode on low-powered hardware, and because you only encode once but you decode many times. <br />
+ <br />
+ <a name="general__lossless_trust"><b>How can I be sure FLAC is lossless?</b></a><br />
+ <a name="general__testing"><b>How much testing has been done on FLAC?</b></a><br />
+ <br />
+ First, FLAC is probably the only lossless compressor that has a published and comprehensive test suite. With the others you rely on the author's personal testing or the longevity of the program. But with FLAC you can download the whole test suite and run it on any version you like, or alter it to test your own data. The test suite checks every function in the API, as well as running many thousands of streams through an encode-decode-verify process, to test every nook and cranny of the system. Even on a fast machine the full test suite takes hours. The full test suite must pass on several platforms before a release is made.<br />
+ <br />
+ Second, you can always use the <span class="argument">-V</span> option with <span class="commandname">flac</span> (also supported by most GUI frontends) to verify while encoding. With this option, a decoder is run in parallel to the encoder and its output is compared against the original input. If a difference is found <span class="commandname">flac</span> will stop with an error.<br />
+ <br />
+ Finally, FLAC is used by many people and has been judged stable enough by many software and hardware makers to be incorporated into their products.<br />
+ <br />
+ <a name="general__lowest_bitrate"><b>What is the lowest bitrate (or highest compression) achievable with FLAC?</b></a><br />
+ <br />
+ With FLAC you do not specify a bitrate like with some lossy codecs. It's more like specifying a quality with Vorbis or MPC, except with FLAC the quality is always "lossless" and the resulting bitrate is roughly proportional to the amount of information in the original signal. You cannot control the bitrate much and the result can be from around 100% of the input rate (if you are encoding noise), down to almost 0 (encoding silence).<br />
+ <br />
+ <a name="general__channels"><b>How many channels does FLAC support?</b></a><br />
+ <br />
+ FLAC supports from 1 to 8 channels per stream. Channels are only grouped in FLAC to take advantage of interchannel correlation and to define common channel assignments (like stereo L/R, 5.1 surround, et cetera). When encoding a large number of independent channels it is expected that they are coded separately and if required, multiplexed together in a suitable container like Ogg or Matroska.<br />
+ <br />
+ <a name="general__samples"><b>What kind of audio samples does FLAC support?</b></a><br />
+ <br />
+ FLAC supports linear PCM samples with a resolution between 4 and 32 bits per sample. FLAC does not support floating point samples. In some cases it is possible to losslessly transform samples from an incompatible range to a FLAC-compatible range before encoding.<br />
+ <br />
+ FLAC supports linear sample rates from 1Hz - 655350Hz in 1Hz increments.<br />
+ <br />
+ <a name="general__samples_fp"><b>Will FLAC ever support floating-point samples?</b></a><br />
+ <br />
+ It's unlikely FLAC will ever support floating-point samples natively. The main application for floating-point is audio engineering, which demands easy editing and very high speed for both encoding and decoding above everything else.<br />
+ <br />
+ FLAC is designed as a consumer audio format. It trades ease of editing for a featureful, robust transport layer more suited for playback, and encoding speed for more compression and faster decompression.

+
+ <a name="tools__eac_and_flac"><b>How do I set up EAC to rip directly to FLAC?</b></a><br />
+ <br />
+ See Case's excellent <a href="http://www.saunalahti.fi/cse/EAC/index.html">EAC configuration page</a>. Or use <a href="http://www.legroom.net/software/autoflac">AutoFLAC</a> or <a href="http://mareo.netfirms.com/">MAREO</a> to rip to FLAC or multiple formats at once.<br />
+ <br />
+ <a name="tools__runtime75"><b>Why am I getting "Run-time error '75': Path/File access error" with FLAC Frontend?</b></a><br />
+ <br />
+ You are probably using an old version of FLAC Frontend. Try downloading a new version from <a href="http://flacfrontend.sf.net/">this sourceforge page</a><br />
+ <br />
+ <a name="tools__option_blocking"><b>How do I encode a file that starts with a dash?</b></a><br />
+ <br />
+ When using <span class="commandname">flac</span> to encode on the command-line, a file that starts with a dash will be treated as an option, but there is a simple workaround. Use <span class="argument">--</span> to signal the end of options and the beginning of filenames, like so:<br />
+ <br />
+ <span class="code">flac -V -- -01-name.wav</span><br />
+ <br />
+ <a name="tools__long_meta_edits"><b>Why does it take so long to edit some FLAC files with metaflac?</b></a><br />
+ <br />
+ Since metadata is stored at the beginning of a FLAC file, changing the length of it can sometimes cause the whole file to be rewritten. You can avoid this by adding padding with <span class="commandname">flac</span> when you encode, or with <span class="commandname">metaflac</span> after encoding. By default, <span class="commandname">flac</span> adds 8k of padding; you can change this amount if you need more or less.<br />
+ <br />
+ <a name="tools__wildcards_on_windows"><b>Why don't wildcards for file names like *.flac or *.wav work with <span class="commandname">flac</span>/<span class="commandname">metaflac</span> on Windows?</b></a><br />
+ <br />
+ The Windows command shells (cmd.exe, command.com) implement wildcard handling differently than most other shells, leaving it up to the program to do everything including difficult and ambiguous cases. For an explanation of why wildcards on cmd.exe/command.com are dangerous, see <a href="http://www.hydrogenaud.io/forums/index.php?showtopic=50667&st=75&p=466078&#entry466078">here</a>. Better command shells for Windows exist, e.g. from <a href="http://cygwin.com/">Cygwin</a>. A workaround with the Windows shells is to do something like:<br />
+ <br />
+ <tt>for %F in (*.wav) do flac "%F"</tt><br />
+ <br />
+ but care must still be taken that the command will execute as intended.<br />
+ <br />
+ <a name="tools__hardware_prob"><b>I compressed a file to FLAC with verify on, and flac said "Verify FAILED!" Why?</b></a><br />
+ <br />
+ The only known cause of verify errors is faulty hardware. The dead giveaway is that if you repeat the exact same command, the error occurs in a different place or not at all. This can also happen when decoding or testing a FLAC file. If this is happening it is your hardware and not a FLAC bug.<br />
+ <br />
+ The problem is usually caused by overclocking/overheating the CPU or bad RAM. Try one of the many free programs available for testing hardware (e.g. <a href="http://www.memtest.org/">Memtest</a>).<br />

+ If you ever have a verify error that fails at the same place every time, please <a href="faq.html#project__submit_bug">file a bug</a>, uploading a sample according to <a href="http://sourceforge.net/p/flac/bugs/42/">the instructions found at the bottom of this bug report</a>.<br />
+ <br />
+ <a name="tools__wave_flac_wave"><b>I compressed a WAVE file to FLAC, then decompressed to WAVE, and the two weren't identical. Why?</b></a><br />
+ <a name="tools__skipped_subchunk"><b>I compressed a WAVE file to FLAC and it said "warning: skipping unknown sub-chunk LIST". Why?</b></a><br />
+ <br />
+ WAVE is a complicated standard; many kinds of data besides audio data can be put in it. Most likely what has happened is that the application that created the original WAVE file also added some extra information for it's own use, which FLAC does not store or recreate by default (but can with the <span class="argument"><a href="documentation_tools_flac.html#flac_options_keep_foreign_metadata">--keep-foreign-metadata</a></span> option) (<a href="faq.html#tools__two_bytes_short">see also</a>). The audio data in the two WAVE files will be identical. There are other tools to compare just the audio content of two WAVE files; <a href="http://www.exactaudiocopy.de/">ExactAudioCopy</a> has such a feature.<br />
+ <br />
+ For the more technically inclined, by default FLAC only stores what is in the 'fmt ' and 'data' sub-chunks of a WAVE file. <a href="faq.html#general__no_wave_metadata">(see also)</a><br />
+ <br />
+ <a name="tools__two_bytes_short"><b>I decoded a FLAC file and the WAVE is 2 bytes shorter than the original. Why?</b></a><br />
+ <br />
+ The difference is probably that between an 18-byte 'fmt ' subchunk in the original WAVE vs. a 16-byte one in the decoded WAVE. With WAVE there is more than one way to write identical formatting information, but FLAC always writes the most common legal form. <a href="faq.html#tools__wave_flac_wave">(see also)</a><br />
+ <br />
+ <a name="tools__not_streamable"><b>Why did I get "ERROR initializing encoder, state = FLAC__STREAM_ENCODER_NOT_STREAMABLE"?</b></a><br />
+ <br />
+ You specified encoding options that are outside the <a href="format.html#subset">Streamable subset</a>. If that is what you really wanted and you understand the consequences, you can use <span class="code">flac --lax</span> to generate a non-Subset stream. The resulting file may not be streamable or play in all players.<br />
+ <br />
+ <a name="tools__different_sizes"><b>Why doesn't the same file compressed on different machines with the same options yield the same FLAC file?</b></a><br />
+ <br />
+ It's not supposed to, and neither does it mean either encoding was bad. There are many variations between different machines or even different builds of <span class="commandname">flac</span> on the same machine that can lead to small differences in the FLAC file, even if they have the exact same final size. This is normal.
+
+ <h2>
+ <b>API</b>
+ </h2>
+
+ <a name="api__release_versioning"><b>Why does your API change for point releases?</b></a><br />
+ <br />
+ The FLAC release numbering scheme of MAJOR.MINOR.MICRO reflects the state of the FLAC format, not the API. This is most intuitive for users, at the expense of flustering developers. The shared library number (derived from the libtool current:revision:age number) is the indicator of binary API compatibility. As of FLAC 1.1.3, the current, revision, and age numbers are also <tt>#define</tt>d in the library headers to make porting easier; see the <a href="api/group__porting.html">porting guide</a>.<br />
+ <br />
+ <a name="api__frame_length"><b>How can I determine the encoded frame length?</b></a><br />
+ <br />
+ With native FLAC, it is not possible to determine the frame length without decoding. Probably if I had it all to do again I would have constrained the possible block sizes, which would have made it more practical to put the frame length in the frame header. For an example of how to find the frame boundaries in a stream, see the source code to <span class="commandname">metaflac</span>, in the functionality that adds seek points.<br />
+ <br />
+ With Ogg FLAC, it can be calculated from the Ogg page header.
+
+ <h2>
+ <b>Project</b>
+ </h2>
+
+ <a name="project__lists"><b>Where are the mailing lists, forums, discussion areas, etc.?</b></a><br />
+ <br />
+ There are a few places. The main discussions happen on <a href="http://lists.xiph.org/mailman/listinfo">the official FLAC mailing lists</a> (you must subscribe to post). Also, there is a lot of discussion relating to FLAC on <a href="http://www.hydrogenaud.io/">Hydrogen Audio</a>.<br />
+ <br />
+ <a name="project__submit_bug"><b>How do I submit a bug report?</b></a><br />
+ <br />
+ First, <a href="http://sourceforge.net/p/flac/bugs/">visit the bug tracking page</a> and do a little searching of both open and closed bugs to see if yours is already there. If you have something truly new submit a new bug there. <b>Make sure</b> to monitor the bug or include your email address in the description. Include as much information as possible: the version of FLAC that you are running, the name and version of any frontend you are running, your operating system and version, your CPU type and speed, the amount of memory you have, where you downloaded FLAC from, the exact error message (if any) copied from the console, and anything else you may think will help.

+ FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see <a href="http://xiph.org/flac/links.html#hardware">supported devices</a>) just like you would an MP3 file.<br />
+ <br />
+ FLAC stands out as the <a href="http://xiph.org/flac/comparison.html">fastest and most widely supported lossless audio codec</a>, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.<br />
+ <br />
+ FLAC supports tagging, cover art, and fast seeking. FLAC is freely available and supported on most operating systems, including Windows, "unix" (Linux, *BSD, Solaris, OS X, IRIX), BeOS, OS/2, and Amiga.<br />
+ <br />
+ There are <a href="http://xiph.org/flac/links.html">many programs and devices that support FLAC</a>, but the core FLAC project here maintains the format and provides <a href="documentation_tools.html">programs</a> and <a href="developers.html">libraries</a> for working with FLAC files. See <a href="http://xiph.org/flac/download.html">Getting FLAC</a> for instructions on downloading and installing the official FLAC tools, or <a href="http://xiph.org/flac/documentation_tasks.html">Using FLAC</a> for instructions and guides on playing FLAC files, ripping CDs to FLAC, etc.<br />
+ <br />
+ When we say that FLAC is "Free" it means more than just that it is available at no cost. It means that the specification of the format is fully open to the public to be used for any purpose (the FLAC project reserves the right to set the FLAC specification and certify compliance), and that neither the FLAC format nor any of the implemented encoding/decoding methods are covered by any known patent. It also means that all the source code is available under open-source licenses. It is the first truly open and free lossless audio format. (For more information, see the <a href="license.html">license page</a>.)<br />
+ <br />
+ Notable features of FLAC:
+ <ul>
+ <li>
+ <b>Lossless</b>: The encoding of audio (PCM) data incurs no loss of information, and the decoded audio is bit-for-bit identical to what went into the encoder. Each frame contains a 16-bit CRC of the frame data for detecting transmission errors. The integrity of the audio data is further insured by storing an <a href="http://userpages.umbc.edu/~mabzug1/cs/md5/md5.html">MD5 signature</a> of the original unencoded audio data in the file header, which can be compared against later during decoding or testing.
+ </li>
+ <li>
+ <b>Fast</b>: FLAC is asymmetric in favor of decode speed. Decoding requires only integer arithmetic, and is much less compute-intensive than for most perceptual codecs. Real-time decode performance is easily achievable on even modest hardware.
+ </li>
+ <li>
+ <b>Hardware support</b>: FLAC is supported by <a href="http://xiph.org/flac/links.html#hardware">dozens of consumer electronic devices</a>, from portable players, to home stereo equipment, to car stereo.
+ </li>
+ <li>
+ <b>Flexible metadata</b>: FLAC's metadata system supports tags, cover art, seek tables, and cue sheets. Applications can write their own <a href="format.html#def_APPLICATION">APPLICATION</a> metadata once they <a href="id.html">register an ID</a>. New metadata blocks can be defined and implemented in future versions of FLAC without breaking older streams or decoders.
+ </li>
+ <li>
+ <b>Seekable</b>: FLAC supports fast sample-accurate seeking. Not only is this useful for playback, it makes FLAC files suitable for use in editing applications.
+ </li>
+ <li>
+ <b>Streamable</b>: Each FLAC frame contains enough data to decode that frame. FLAC does not even rely on previous or following frames. FLAC uses sync codes and CRCs (similar to MPEG and other formats), which, along with framing, allow decoders to pick up in the middle of a stream with a minimum of delay.
+ </li>
+ <li>
+ <b>Suitable for archiving</b>: FLAC is an open format, and there is no generation loss if you need to convert your data to another format in the future. In addition to the frame CRCs and MD5 signature, <span class="commandname">flac</span> has a verify option that decodes the encoded stream in parallel with the encoding process and compares the result to the original, aborting with an error if there is a mismatch.
+ </li>
+ <li>
+ <b>Convenient CD archiving</b>: FLAC has a <a href="format.html#def_CUESHEET">"cue sheet"</a> metadata block for storing a CD table of contents and all track and index points. For instance, you can rip a CD to a single file, then import the CD's extracted cue sheet while encoding to yield a single file representation of the entire CD. If your original CD is damaged, the cue sheet can be exported later in order to burn an exact copy.
+ </li>
+ <li>
+ <b>Error resistant</b>: Because of FLAC's framing, stream errors limit the damage to the frame in which the error occurred, typically a small fraction of a second worth of data. Contrast this with some other lossless codecs, in which a single error destroys the remainder of the stream.
+ </li>
+ </ul>
+ What FLAC is <b>not</b>:
+ <ul>
+ <li>
+ Lossy. FLAC is intended for lossless compression only, as there are many good lossy formats already, such as <a href="http://xiph.org/vorbis">Vorbis</a>, <a href="http://www.musepack.net/">MPC</a>, and <a href="http://www.mp3-tech.org/">MP3</a> (see <a href="http://lame.sourceforge.net/">LAME</a> for an excellent open-source implementation).
+ </li>
+ <li>
+ DRM. There is no intention to add any copy prevention methods. Of course, we can't stop someone from encrypting a FLAC stream in another container (e.g. the way Apple encrypts AAC in MP4 with FairPlay), that is the choice of the user.
+ </li>
+ </ul>

+ <br />
+ It is a known fact that no algorithm can losslessly compress all possible input, so most compressors restrict themselves to a useful domain and try to work as well as possible within that domain. FLAC's domain is audio data. Though it can losslessly <b>code</b> any input, only certain kinds of input will get smaller. FLAC exploits the fact that audio data typically has a high degree of sample-to-sample correlation.<br />
+ <br />
+ Within the audio domain, there are many possible subdomains. For example: low bitrate speech, high-bitrate multi-channel music, etc. FLAC itself does not target a specific subdomain but many of the default parameters of the reference encoder are tuned to CD-quality music data (i.e. 44.1kHz, 2 channel, 16 bits per sample). The effect of the encoding parameters on different kinds of audio data will be examined later.<br />
+ <br />
+ <a name="architecture"><font size="+1"><b><u>Architecture</u></b></font></a><br />
+ <br />
+ Similar to many audio coders, a FLAC encoder has the following stages:
+ <ul>
+ <li>
+ <a href="#blocking">Blocking</a>. The input is broken up into many contiguous blocks. With FLAC, the blocks may vary in size. The optimal size of the block is usually affected by many factors, including the sample rate, spectral characteristics over time, etc. Though FLAC allows the block size to vary within a stream, the reference encoder uses a fixed block size.
+ </li>
+ <li>
+ <a href="#interchannel">Interchannel Decorrelation</a>. In the case of stereo streams, the encoder will create mid and side signals based on the average and difference (respectively) of the left and right channels. The encoder will then pass the best form of the signal to the next stage.
+ </li>
+ <li>
+ <a href="#prediction">Prediction</a>. The block is passed through a prediction stage where the encoder tries to find a mathematical description (usually an approximate one) of the signal. This description is typically much smaller than the raw signal itself. Since the methods of prediction are known to both the encoder and decoder, only the parameters of the predictor need be included in the compressed stream. FLAC currently uses four different classes of predictors (described in the <a href="#prediction">prediction</a> section), but the format has reserved space for additional methods. FLAC allows the class of predictor to change from block to block, or even within the channels of a block.
+ </li>
+ <li>
+ <a href="#residualcoding">Residual coding</a>. If the predictor does not describe the signal exactly, the difference between the original signal and the predicted signal (called the error or residual signal) must be coded losslessy. If the predictor is effective, the residual signal will require fewer bits per sample than the original signal. FLAC currently uses only one method for encoding the residual (see the <a href="#residualcoding">Residual coding</a> section), but the format has reserved space for additional methods. FLAC allows the residual coding method to change from block to block, or even within the channels of a block.
+ </li>
+ </ul>
+ In addition, FLAC specifies a metadata system, which allows arbitrary information about the stream to be included at the beginning of the stream.<br />
+ <br />
+ <a name="definitions"><font size="+1"><b><u>Definitions</u></b></font></a><br />
+ <br />
+ Many terms like "block" and "frame" are used to mean different things in different encoding schemes. For example, a frame in MP3 corresponds to many samples across several channels, whereas an S/PDIF frame represents just one sample for each channel. The definitions we use for FLAC follow. Note that when we talk about blocks and subblocks we are referring to the raw unencoded audio data that is the input to the encoder, and when we talk about frames and subframes, we are referring to the FLAC-encoded data.
+ <ul>
+ <li>
+ <b>Block</b>: One or more audio samples that span several channels.
+ </li>
+ <li>
+ <b>Subblock</b>: One or more audio samples within a channel. So a block contains one subblock for each channel, and all subblocks contain the same number of samples.
+ </li>
+ <li>
+ <b>Blocksize</b>: The number of samples in any of a block's subblocks. For example, a one second block sampled at 44.1KHz has a blocksize of 44100, regardless of the number of channels.
+ </li>
+ <li>
+ <b>Frame</b>: A frame header plus one or more subframes.
+ </li>
+ <li>
+ <b>Subframe</b>: A subframe header plus one or more encoded samples from a given channel. All subframes within a frame will contain the same number of samples.
+ </li>
+ </ul>
+ <a name="blocking"><font size="+1"><b><u>Blocking</u></b></font></a><br />
+ <br />
+ The size used for blocking the audio data has a direct effect on the compression ratio. If the block size is too small, the resulting large number of frames mean that excess bits will be wasted on frame headers. If the block size is too large, the characteristics of the signal may vary so much that the encoder will be unable to find a good predictor. In order to simplify encoder/decoder design, FLAC imposes a minimum block size of 16 samples, and a maximum block size of 65535 samples. This range covers the optimal size for all of the audio data FLAC supports.<br />
+ <br />
+ Currently the reference encoder uses a fixed block size, optimized on the sample rate of the input. Future versions may vary the block size depending on the characteristics of the signal.<br />
+ <br />
+ Blocked data is passed to the predictor stage one subblock (channel) at a time. Each subblock is independently coded into a subframe, and the subframes are concatenated into a frame. Because each channel is coded separately, it means that one channel of a stereo frame may be encoded as a constant subframe, and the other an LPC subframe.<br />
+ <br />
+ <a name="interchannel"><font size="+1"><b><u>Interchannel Decorrelation</u></b></font></a><br />
+ <br />
+ In stereo streams, many times there is an exploitable amount of correlation between the left and right channels. FLAC allows the frames of stereo streams to have different channel assignments, and an encoder may choose to use the best representation on a frame-by-frame basis.
+ <ul>
+ <li>
+ <b>Independent</b>. The left and right channels are coded independently.
+ </li>
+ <li>
+ <b>Mid-side</b>. The left and right channels are transformed into mid and side channels. The mid channel is the midpoint (average) of the left and right signals, and the side is the difference signal (left minus right).
+ </li>
+ <li>
+ <b>Left-side</b>. The left channel and side channel are coded.
+ </li>
+ <li>
+ <b>Right-side</b>. The right channel and side channel are coded
+ </li>
+ </ul>
+ Surprisingly, the left-side and right-side forms can be the most efficient in many frames, even though the raw number of bits per sample needed for the original signal is slightly more than that needed for independent or mid-side coding.<br />
+ <br />
+ <a name="prediction"><font size="+1"><b><u>Prediction</u></b></font></a><br />
+ <br />
+ FLAC uses four methods for modeling the input signal:
+ <ul>
+ <li>
+ <b>Verbatim</b>. This is essentially a zero-order predictor of the signal. The predicted signal is zero, meaning the residual is the signal itself, and the compression is zero. This is the baseline against which the other predictors are measured. If you feed random data to the encoder, the verbatim predictor will probably be used for every subblock. Since the raw signal is not actually passed through the residual coding stage (it is added to the stream 'verbatim'), the encoding results will not be the same as a zero-order linear predictor.
+ </li>
+ <li>
+ <b>Constant</b>. This predictor is used whenever the subblock is pure DC ("digital silence"), i.e. a constant value throughout. The signal is run-length encoded and added to the stream.
+ </li>
+ <li>
+ <b>Fixed linear predictor</b>. FLAC uses a class of computationally-efficient fixed linear predictors (for a good description, see <a href="http://www.hpl.hp.com/techreports/1999/HPL-1999-144.pdf">audiopak</a> and <a href="http://svr-www.eng.cam.ac.uk/reports/abstracts/robinson_tr156.html">shorten</a>). FLAC adds a fourth-order predictor to the zero-to-third-order predictors used by Shorten. Since the predictors are fixed, the predictor order is the only parameter that needs to be stored in the compressed stream. The error signal is then passed to the residual coder.
+ </li>
+ <li>
+ <b>FIR Linear prediction</b>. For more accurate modeling (at a cost of slower encoding), FLAC supports up to 32nd order FIR linear prediction (again, for information on linear prediction, see <a href="http://www.hpl.hp.com/techreports/1999/HPL-1999-144.pdf">audiopak</a> and <a href="http://svr-www.eng.cam.ac.uk/reports/abstracts/robinson_tr156.html">shorten</a>). The reference encoder uses the Levinson-Durbin method for calculating the LPC coefficients from the autocorrelation coefficients, and the coefficients are quantized before computing the residual. Whereas encoders such as Shorten used a fixed quantization for the entire input, FLAC allows the quantized coefficient precision to vary from subframe to subframe. The FLAC reference encoder estimates the optimal precision to use based on the block size and dynamic range of the original signal.
+ </li>
+ </ul>
+ <a name="residualcoding"><font size="+1"><b><u>Residual Coding</u></b></font></a><br />
+ <br />
+ FLAC currently defines two similar methods for the coding of the error signal from the prediction stage. The error signal is coded using Rice codes in one of two ways: 1) the encoder estimates a single Rice parameter based on the variance of the residual and Rice codes the entire residual using this parameter; 2) the residual is partitioned into several equal-length regions of contiguous samples, and each region is coded with its own Rice parameter based on the region's mean. (Note that the first method is a special case of the second method with one partition, except the Rice parameter is based on the residual variance instead of the mean.)<br />
+ <br />
+ The FLAC format has reserved space for other coding methods. Some possibilities for volunteers would be to explore better context-modeling of the Rice parameter, or Huffman coding. See <a href="http://www.hpl.hp.com/techreports/98/HPL-98-193.html">LOCO-I</a> and <a href="http://www.cs.tut.fi/~albert/Dev/pucrunch/packing.html">pucrunch</a> for descriptions of several universal codes.<br />
+ <br />
+ <a name="format_overview"><font size="+1"><b><u>Format</u></b></font></a><br />
+ <br />
+ This section specifies the FLAC bitstream format. FLAC has no format version information, but it does contain reserved space in several places. Future versions of the format may use this reserved space safely without breaking the format of older streams. Older decoders may choose to abort decoding or skip data encoded with newer methods. Apart from reserved patterns, in places the format specifies invalid patterns, meaning that the patterns may never appear in any valid bitstream, in any prior, present, or future versions of the format. These invalid patterns are usually used to make the synchronization mechanism more robust.<br />
+ <br />
+ All numbers used in a FLAC bitstream are integers; there are no floating-point representations. All numbers are big-endian coded. All numbers are unsigned unless otherwise specified.<br />
+ <br />
+ Before the formal description of the stream, an overview might be helpful.
+ <ul>
+ <li>
+ A FLAC bitstream consists of the "fLaC" marker at the beginning of the stream, followed by a mandatory metadata block (called the STREAMINFO block), any number of other metadata blocks, then the audio frames.
+ </li>
+ <li>
+ FLAC supports up to 128 kinds of metadata blocks; currently the following are defined:
+ <ul>
+ <li><a name="def_STREAMINFO"><b>STREAMINFO</b></a>: This block has information about the whole stream, like sample rate, number of channels, total number of samples, etc. It must be present as the first metadata block in the stream. Other metadata blocks may follow, and ones that the decoder doesn't understand, it will skip.</li>
+ <li><a name="def_APPLICATION"><b>APPLICATION</b></a>: This block is for use by third-party applications. The only mandatory field is a 32-bit identifier. This ID is granted upon request to an application by the FLAC maintainers. The remainder is of the block is defined by the registered application. Visit the <a href="id.html">registration page</a> if you would like to register an ID for your application with FLAC.</li>
+ <li><a name="def_PADDING"><b>PADDING</b></a>: This block allows for an arbitrary amount of padding. The contents of a PADDING block have no meaning. This block is useful when it is known that metadata will be edited after encoding; the user can instruct the encoder to reserve a PADDING block of sufficient size so that when metadata is added, it will simply overwrite the padding (which is relatively quick) instead of having to insert it into the right place in the existing file (which would normally require rewriting the entire file).</li>
+ <li><a name="def_SEEKTABLE"><b>SEEKTABLE</b></a>: This is an optional block for storing seek points. It is possible to seek to any given sample in a FLAC stream without a seek table, but the delay can be unpredictable since the bitrate may vary widely within a stream. By adding seek points to a stream, this delay can be significantly reduced. Each seek point takes 18 bytes, so 1% resolution within a stream adds less than 2k. There can be only one SEEKTABLE in a stream, but the table can have any number of seek points. There is also a special 'placeholder' seekpoint which will be ignored by decoders but which can be used to reserve space for future seek point insertion.</li>
+ <li><a name="def_VORBIS_COMMENT"><b>VORBIS_COMMENT</b></a>: This block is for storing a list of human-readable name/value pairs. Values are encoded using UTF-8. It is an implementation of the <a href="http://xiph.org/vorbis/doc/v-comment.html">Vorbis comment specification</a> (without the framing bit). This is the only officially supported tagging mechanism in FLAC. There may be only one VORBIS_COMMENT block in a stream. In some external documentation, Vorbis comments are called FLAC tags to lessen confusion.</li>
+ <li><a name="def_CUESHEET"><b>CUESHEET</b></a>: This block is for storing various information that can be used in a cue sheet. It supports track and index points, compatible with Red Book CD digital audio discs, as well as other CD-DA metadata such as media catalog number and track ISRCs. The CUESHEET block is especially useful for backing up CD-DA discs, but it can be used as a general purpose cueing mechanism for playback.</li>
+ <li><a name="def_PICTURE"><b>PICTURE</b></a>: This block is for storing pictures associated with the file, most commonly cover art from CDs. There may be more than one PICTURE block in a file. The picture format is similar to the <a href="http://www.id3.org/id3v2.4.0-frames">APIC frame in ID3v2</a>. The PICTURE block has a type, MIME type, and UTF-8 description like ID3v2, and supports external linking via URL (though this is discouraged). The differences are that there is no uniqueness constraint on the description field, and the MIME type is mandatory. The FLAC PICTURE block also includes the resolution, color depth, and palette size so that the client can search for a suitable picture without having to scan them all.</li>
+ </ul>
+ </li>
+ <li>
+ The audio data is composed of one or more audio frames. Each frame consists of a frame header, which contains a sync code, information about the frame like the block size, sample rate, number of channels, et cetera, and an 8-bit CRC. The frame header also contains either the sample number of the first sample in the frame (for variable-blocksize streams), or the frame number (for fixed-blocksize streams). This allows for fast, sample-accurate seeking to be performed. Following the frame header are encoded subframes, one for each channel, and finally, the frame is zero-padded to a byte boundary. Each subframe has its own header that specifies how the subframe is encoded.
+ </li>
+ <li>
+ Since a decoder may start decoding in the middle of a stream, there must be a method to determine the start of a frame. A 14-bit sync code begins each frame. The sync code will not appear anywhere else in the frame header. However, since it may appear in the subframes, the decoder has two other ways of ensuring a correct sync. The first is to check that the rest of the frame header contains no invalid data. Even this is not foolproof since valid header patterns can still occur within the subframes. The decoder's final check is to generate an 8-bit CRC of the frame header and compare this to the CRC stored at the end of the frame header.
+ </li>
+ <li>
+ Again, since a decoder may start decoding at an arbitrary frame in the stream, each frame header must contain some basic information about the stream because the decoder may not have access to the STREAMINFO metadata block at the start of the stream. This information includes sample rate, bits per sample, number of channels, etc. Since the frame header is pure overhead, it has a direct effect on the compression ratio. To keep the frame header as small as possible, FLAC uses lookup tables for the most commonly used values for frame parameters. For instance, the sample rate part of the frame header is specified using 4 bits. Eight of the bit patterns correspond to the commonly used sample rates of 8/16/22.05/24/32/44.1/48/96 kHz. However, odd sample rates can be specified by using one of the 'hint' bit patterns, directing the decoder to find the exact sample rate at the end of the frame header. The same method is used for specifying the block size and bits per sample. In this way, the frame header size stays small for all of the most common forms of audio data.
+ </li>
+ <li>
+ Individual subframes (one for each channel) are coded separately within a frame, and appear serially in the stream. In other words, the encoded audio data is NOT channel-interleaved. This reduces decoder complexity at the cost of requiring larger decode buffers. Each subframe has its own header specifying the attributes of the subframe, like prediction method and order, residual coding parameters, etc. The header is followed by the encoded audio data for that channel.
+ </li>
+ <li>
+ <a name="subset">FLAC</a> specifies a subset of itself as the Subset format. The purpose of this is to ensure that any streams encoded according to the Subset are truly "streamable", meaning that a decoder that cannot seek within the stream can still pick up in the middle of the stream and start decoding. It also makes hardware decoder implementations more practical by limiting the encoding parameters such that decoder buffer sizes and other resource requirements can be easily determined. <span class="commandname">flac</span> generates Subset streams by default unless the "--lax" command-line option is used. The Subset makes the following limitations on what may be used in the stream:
+ <ul>
+ <li>
+ The blocksize bits in the <a href="#frame_header">frame header</a> must be 0001-1110. The blocksize must be <=16384; if the sample rate is <= 48000Hz, the blocksize must be <=4608.
+ </li>
+ <li>
+ The sample rate bits in the <a href="#frame_header">frame header</a> must be 0001-1110.
+ </li>
+ <li>
+ The bits-per-sample bits in the <a href="#frame_header">frame header</a> must be 001-111.
+ </li>
+ <li>
+ If the sample rate is <= 48000Hz, the filter order in <a href="#subframe_lpc">LPC subframes</a> must be less than or equal to 12, i.e. the subframe type bits in the <a href="#subframe_header">subframe header</a> may not be 101100-111111.
+ </li>
+ <li>
+ The Rice partition order in a <a href="#partitioned_rice">Rice-coded residual section</a> must be less than or equal to 8.
+ </li>
+ </ul>
+ </li>
+ </ul>
+
+ The following tables constitute a formal description of the FLAC format. Numbers in angle brackets indicate how many bits are used for a given field.<br />

According to the Red Book, the lead-in must be silence and CD grabbing software does not usually store it; additionally, the lead-in must be at least two seconds but may be longer. For these reasons the lead-in length is stored here so that the absolute position of the first track can be computed. Note that the lead-in stored here is the number of samples up to the first index point of the first track, not necessarily to INDEX 01 of the first track; even the first track may have INDEX 00 data.

If it is <tt>1</tt> (variable-blocksize), the frame header encodes the frame's starting sample number itself. (In the case of a fixed-blocksize stream, only the last block may be shorter than the stream blocksize; its starting sample number will be calculated as the frame number times the previous frame's blocksize, or zero if it is the first frame).

+ FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see <a href="http://xiph.org/flac/links.html#hardware">supported devices</a>) just like you would an MP3 file.<br />
+ <br />
+ FLAC stands out as the <a href="http://xiph.org/flac/comparison.html">fastest and most widely supported lossless audio codec</a>, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.<br />

+ ogg mapping
+ </div>
+ <div class="box_header"></div>
+ <div class="box_body">
+ This page specifies the way in which compressed FLAC data is encapsulated in an Ogg transport layer. It assumes basic knowledge of the <a href="format.html">FLAC format</a> and <a href="http://xiph.org/vorbis/doc/oggstream.html">Ogg structure</a> and <a href="http://xiph.org/vorbis/doc/framing.html">framing</a>.<br />
+ <br />
+ The original FLAC format includes a very thin transport system. This system of compressed FLAC audio data mixed with a thin transport has come to be known as 'native FLAC'. The transport consists of audio frame headers and footers which contain synchronization patterns, timecodes, and checksums (but notably not frame lengths), and a metadata system. It is very lightweight and does not support more elaborate transport mechanisms such as multiple logical streams, but it has served its purpose well.<br />
+ <br />
+ The native FLAC transport is not a transport "layer" in the way of standard codec design because it cannot be entirely separated from the payload. Though the metadata system can be separated, the frame header includes both data that belongs in the transport (sync pattern, timecode, checksum) and data that belongs in the compressed packets (audio parameters like channel assignments, sample rate, etc).<br />
+ <br />
+ This presents a problem when trying to encapsulate FLAC in other true transport layers; the choice has to be made between redundancy and complexity. In pursuit of correctness, a mapping could be created that removed from native FLAC the transport data, and merged the remaining frame header information into the audio packets. The disadvantage is that current native FLAC decoder software could not be used to decode because of the tight coupling with the transport. Either a separate decoding implementation would have to be created and maintained, or an Ogg FLAC decoder would have to synthesize native FLAC frames from Ogg FLAC packets and feed them to a native FLAC decoder.<br />
+ <br />
+ The alternative is to treat native FLAC frames as Ogg packets and accept the transport redundancy. It turns out that this is not much of a penalty; a maximum of 12 bytes per frame will be wasted. Given the common case of stereo CD audio encoded with a blocksize of 4096 samples, a compressed frame will be 4-16 Kbytes. The redundancy amounts to a fraction of a percent.<br />
+ <br />
+ In the interest of simplicity and expediency, the second method was chosen for the first official FLAC->Ogg mapping. A mapping version is included in the first packet so that a less redundant mapping can be defined in the future.<br />
+ <br />
+ It should also be noted that support for encapsulating FLAC in Ogg has been present in the FLAC tools since version 1.0.1. However, the mappings used were never formalized and have insurmountable problems. For that reason, Ogg FLAC streams created with <span class="commandname">flac</span> versions before 1.1.1 should be decoded and re-encoded with <span class="commandname">flac</span> 1.1.1 or later (<span class="commandname">flac</span> 1.1.1 can decode all previous Ogg FLAC files, but files made prior to 1.1.0 don't support seeking). Since the support for Ogg FLAC before FLAC 1.1.1 was limited, we hope this will not result in too much inconvenience.<br />
+ <br />
+ Version 1.0 of the FLAC-to-Ogg mapping then is a simple identifying header followed by pure native FLAC data, as follows:
+ <ul>
+ <li>
+ The first packet of a stream consists of:
+ <ul>
+ <li>The one-byte packet type 0x7F</li>
+ <li>The four-byte ASCII signature "FLAC", i.e. 0x46, 0x4C, 0x41, 0x43</li>
+ <li>A one-byte binary major version number for the mapping, e.g. 0x01 for mapping version 1.0</li>
+ <li>A one-byte binary minor version number for the mapping, e.g. 0x00 for mapping version 1.0</li>
+ <li>A two-byte, big-endian binary number signifying the number of header (non-audio) packets, not including this one. This number may be zero (0x0000) to signify 'unknown' but be aware that some decoders may not be able to handle such streams.</li>
+ <li>The four-byte ASCII native FLAC signature "fLaC" according to the <a href="format.html#stream">FLAC format specification</a></li>
+ <li>The <a href="format.html#metadata_block">STREAMINFO</a> metadata block for the stream.</li>
+ </ul>
+ This first packet is the only packet in the first page of the stream. This results in a first Ogg page of exactly 79 bytes at the very beginning of the logical stream.
+ </li>
+ <li>
+ This first page is marked 'beginning of stream' in the page flags.
+ </li>
+ <li>
+ The first packet is followed by one or more header packets. Each such packet will contain a single <a href="format.html#metadata_block">native FLAC metadata block</a>. The first of these must be a VORBIS_COMMENT block. These packets may span page boundaries but the last will finish the page on which it ends, so that the first audio packet begins a page. The first byte of these metadata packets serves also as the packet type, and has a legal range of (0x01-0x7E,0x81-0xFE).
+ </li>
+ <li>
+ The granule position of these first pages containing only headers is zero.
+ </li>
+ <li>
+ The first audio packet of the logical stream begins a fresh Ogg page.
+ </li>
+ <li>
+ Native FLAC audio frames appear as subsequent packets in the stream. Each packet corresponds to one FLAC audio frame. The first byte of each packet serves as the packet type. Since audio packets are native FLAC frames, this first byte will be always 0xFF according to the <a href="format.html#frame_header">native FLAC format specification</a>.
+ </li>
+ <li>
+ The last page is marked 'end of stream' in the page flags.
+ </li>
+ <li>
+ FLAC packets may span page boundaries.
+ </li>
+ <li>
+ The granule position of pages containing FLAC audio follows the same semantics as that for Ogg-encapsulated Vorbis as described <a href="http://xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-126000A">here</a>.
+ </li>
+ <li>
+ Redundant fields in the STREAMINFO packet may be set to zero (indicating "unknown" in native FLAC), which also facilitates single-pass encoding. These fields are: the minimum and maximum frame sizes, the total samples count, and the MD5 signature. "Unknown" values for these fields will not prevent a compliant native FLAC or Ogg FLAC decoder from decoding the stream.

+ It is intended that the first six bytes of any version of FLAC-to-Ogg mapping will share the same structure, namely, the four-byte signature and two-byte version number.<br />
+ <br />
+ There is an implicit hint to the decoder in the mapping version number; mapping versions which share the same major version number should be decodable by decoders of the same major version number, e.g. a 1.x Ogg FLAC decoder should be able to decode any 1.y Ogg FLAC stream, even when x<y. If a mapping breaks this forward compatibility the major version number will be incremented.

+
+3 Design Rules of Encapsulation
+
+ 3.1 File Type Identification
+
+ This specification does not define any brand to declare files
+ which conform to this specification. Files which conform to
+ this specification shall contain at least one brand which
+ supports the requirements and the requirements described in
+ this clause without contradiction in the compatible brands
+ list of the File Type Box. The minimal support of the
+ encapsulation of FLAC bitstreams in ISO Base Media file format
+ requires the 'isom' brand.
+
+ 3.2 Overview of Track Structure
+
+ FLAC coded audio shall be encapsulated into the ISO Base
+ Media File Format as media data within an audio track.
+
+ + The handler_type field in the Handler Reference Box
+ shall be set to 'soun'.
+
+ + The Media Information Box shall contain the Sound Media
+ Header Box.
+
+ + The codingname of the sample entry is 'fLaC'.
+
+ This specification does not define any encapsulation
+ using MP4AudioSampleEntry with objectTypeIndication
+ specified by the MPEG-4 Registration Authority
+ (http://www.mp4ra.org/). See section 'Sample entry
+ format' for the definition of the sample entry.
+
+ + The 'dfLa' box is added to the sample entry to convey
+ initializing information for the decoder.
+
+ See section 'FLAC Specific Box' for the definition of
+ the box contents.
+
+ + A FLAC sample is exactly one FLAC frame as described
+ in the format specification[3]. See section
+ 'Sample format' for details of the frame contents.
+
+ + Every FLAC sample is a sync sample. No pre-roll or
+ lapping is required. See section 'Random Access' for
+ further details.
+
+ 3.3 Definition of a FLAC sample
+
+ 3.3.1 Sample entry format
+
+ For any track containing one or more FLAC bitstreams, a
+ sample entry describing the corresponding FLAC bitstream
+ shall be present inside the Sample Table Box. This version
+ of the specification defines only one sample entry format
+ named FLACSampleEntry whose codingname is 'fLaC'. This
+ sample entry includes exactly one FLAC Specific Box
+ defined in section 'FLAC specific box' as a mandatory box
+ and indicates that FLAC samples described by this sample
+ entry are stored by the sample format described in section
+ 'Sample format'.
+
+ The syntax and semantics of the FLACSampleEntry is shown
+ as follows. The data fields of this box and native
+ FLAC[3] structures encoded within FLAC blocks are both
+ stored in big-endian format, though for purposes of the
+ ISO BMFF container, FLAC native metadata and data blocks
+ are treated as unstructured octet streams.
+
+ class FLACSampleEntry() extends AudioSampleEntry ('fLaC'){
+ FLACSpecificBox();
+ }
+
+ The fields of the AudioSampleEntry portion shall be set as
+ follows:
+
+ + channelcount:
+
+ The channelcount field shall be set equal to the
+ channel count specified by the FLAC bitstream's native
+ METADATA_BLOCK_STREAMINFO header as described in [3].
+ Note that the FLAC FRAME_HEADER structure that begins
+ each FLAC sample redundantly encodes channel number;
+ the number of channels declared in each FRAME_HEADER
+ MUST match the number of channels declared here and in
+ the METADATA_BLOCK_STREAMINFO header.
+
+ + samplesize:
+
+ The samplesize field shall be set equal to the bits
+ per sample specified by the FLAC bitstream's native
+ METADATA_BLOCK_STREAMINFO header as described in [3].
+ Note that the FLAC FRAME_HEADER structure that begins
+ each FLAC sample redundantly encodes the number of
+ bits per sample; the bits per sample declared in each
+ FRAME_HEADER MUST match the samplesize declared here
+ and the bits per sample field declared in the
+ METADATA_BLOCK_STREAMINFO header.
+
+ + samplerate:
+
+ When possible, the samplerate field shall be set
+ equal to the sample rate specified by the FLAC
+ bitstream's native METADATA_BLOCK_STREAMINFO header
+ as described in [3], left-shifted by 16 bits to
+ create the appropriate 16.16 fixed-point
+ representation.
+
+ When the bitstream's native sample rate is greater
+ than the maximum expressible value of 65535 Hz,
+ the samplerate field shall hold the greatest
+ expressible regular division of that rate. I.e.
+ the samplerate field shall hold 48000.0 for
+ native sample rates of 96 and 192 kHz. In the
+ case of unusual sample rates which do not have
+ an expressible regular division, the maximum value
+ of 65535.0 Hz should be used.
+
+ High-rate FLAC bitstreams are common, and the native
+ value from the METADATA_BLOCK_STREAMINFO header in
+ the FLACSpecificBox MUST be read to determine the
+ correct sample rate of the bitstream.
+
+ Note that the FLAC FRAME_HEADER structure that begins
+ each FLAC sample redundantly encodes the sample rate;
+ the sample rate declared in each FRAME_HEADER MUST
+ match the sample rate declared in the
+ METADATA_BLOCK_STREAMINFO header, and here in the
+ AudioSampleEntry portion of the FLACSampleEntry
+ as much as is allowed by the encoding restrictions
+ described above.
+
+ Finally, the FLACSpecificBox carries codec headers:
+
+ + FLACSpecificBox
+
+ This box contains initializing information for the
+ decoder as defined in section 'FLAC specific box'.
+
+ 3.3.2 FLAC Specific Box
+
+ Exactly one FLAC Specific Box shall be present in each
+ FLACSampleEntry. This specification defines version 0
+ of this box. If incompatible changes occur in future
+ versions of this specification, another version number
+ will be defined. The data fields of this box and native
+ FLAC[3] structures encoded within FLAC blocks are both
+ stored in big-endian format, though for purposes of the
+ ISO BMFF container, FLAC native metadata and data blocks
+ are treated as unstructured octet streams.
+
+ The syntax and semantics of the FLAC Specific Box is shown
+ as follows.
+
+ class FLACMetadataBlock {
+ unsigned int(1) LastMetadataBlockFlag;
+ unsigned int(7) BlockType;
+ unsigned int(24) Length;
+ unsigned int(8) BlockData[Length];
+ }
+
+ aligned(8) class FLACSpecificBox
+ extends FullBox('dfLa', version=0, 0){
+ for (i=0; ; i++) { // to end of box
+ FLACMetadataBlock();
+ }
+ }
+
+ + Version:
+
+ The Version field shall be set to 0.
+
+ In the future versions of this specification, this
+ field may be set to other values. And without support
+ of those values, the reader shall not read the fields
+ after this within the FLACSpecificBox.
+
+ + Flags:
+
+ The Flags field shall be set to 0.
+
+ After the FullBox header, the box contains a sequence of
+ FLAC[3] native-metadata block structures that fill the
+ remainder of the box.
+
+ Each FLACMetadataBlock structure consists of three fields
+ filling a total of four bytes that form a FLAC[3] native
+ METADATA_BLOCK_HEADER, followed by raw octet bytes that
+ comprise the FLAC[3] native METADATA_BLOCK_DATA.
+
+ + LastMetadataBlockFlag:
+
+ The LastMetadataBlockFlag field maps semantically to
+ the FLAC[3] native METADATA_BLOCK_HEADER
+ Last-metadata-block flag as defined in the FLAC[3]
+ file specification.
+
+ The LastMetadataBlockFlag is set to 1 if this
+ MetadataBlock is the last metadata block in the
+ FLACSpecificBox. It is set to 0 otherwise.
+
+ + BlockType:
+
+ The BlockType field maps semantically to the FLAC[3]
+ native METADATA_BLOCK_HEADER BLOCK_TYPE field as
+ defined in the FLAC[3] file specification.
+
+ The BlockType is set to a valid FLAC[3] BLOCK_TYPE
+ value that identifies the type of this native metadata
+ block. The BlockType of the first FLACMetadataBlock
+ must be set to 0, signifying this is a FLAC[3] native
+ METADATA_BLOCK_STREAMINFO block.
+
+ + Length:
+
+ The Length field maps semantically to the FLAC[3]
+ native METADATA_BLOCK_HEADER Length field as
+ defined in the FLAC[3] file specification.
+
+ The length field specifies the number of bytes of
+ MetadataBlockData to follow.
+
+ + BlockData
+
+ The BlockData field maps semantically to the FLAC[3]
+ native METADATA_BLOCK_HEADER METADATA_BLOCK_DATA as
+ defined in the FLAC[3] file specification.
+
+ Taken together, the bytes of the FLACMetadataBlock form a
+ complete FLAC[3] native METADATA_BLOCK structure.
+
+ Note that a minimum of a single FLACMetadataBlock,
+ consisting of a FLAC[3] native METADATA_BLOCK_STREAMINFO
+ structure, is required. Should the FLACSpecificBox
+ contain more than a single FLACMetadataBlock structure,
+ the FLACMetadataBlock containing the FLAC[3] native
+ METADATA_BLOCK_STREAMINFO must occur first in the list.
+
+ Other containers that package FLAC audio streams, such as
+ Ogg[4] and Matroska[5], wrap FLAC[3] native metadata without
+ modification similar to this specification. When
+ repackaging or remuxing FLAC[3] streams from another
+ format that contains FLAC[3] native metadata into an ISO
+ BMFF file, the complete FLAC[3] native metadata should be
+ preserved in the ISO BMFF stream as described above. It
+ is also allowed to parse this native metadata and include
+ contextually redundant ISO BMFF-native repackagings and/or
+ reparsings of FLAC[3] native metadata, so long as the
+ native metadata is also preserved.
+
+ 3.3.3 Sample format
+
+ A FLAC sample is exactly one FLAC audio FRAME (as defined
+ in the FLAC[3] file specification) belonging to a FLAC
+ bitstreams. The FLAC sample data begins with a complete
+ FLAC FRAME_HEADER, followed by one FLAC SUBFRAME per
+ channel, any necessary bit padding, and ends with the
+ usual FLAC FRAME_FOOTER.
+
+ Note that the FLAC native FRAME_HEADER structure that
+ begins each FLAC sample redundantly encodes channel count,
+ sample rate, and sample size. The values of these fields
+ must agree both with the values declared in the FLAC
+ METADATA_BLOCK_STREAMINFO structure as well as the
+ FLACSampleEntry box.
+
+ 3.3.4 Duration of a FLAC sample
+
+ The duration of any given FLAC sample is determined by
+ dividing the decoded block size of a FLAC frame, as
+ encoded in the FLAC FRAME's FRAME_HEADER structure, by the
+ value of the timescale field in the Media Header Box.
+ FLAC samples are permitted to have variable durations
+ within a given audio stream. FLAC does not use padding
+ values.
+
+ 3.3.5 Sub-sample
+
+ Sub-samples are not defined for FLAC samples in this
+ specification.
+
+ 3.3.6 Random Access
+
+ This subclause describes the nature of the random access
+ of FLAC sample.
+
+ 3.3.6.1 Random Access Point
+
+ All FLAC samples can be independently decoded
+ i.e. every FLAC sample is a sync sample. The Sync
+ Sample Box shall not be present as long as there are
+ no samples other than FLAC samples in the same
+ track. The sample_is_non_sync_sample field for FLAC
+ samples shall be set to 0.
+
+ 3.4 Basic Structure (informative)

+# Fuzzer for libFLAC decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for FLAC decoder is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+FLAC supports the following two decoder API's for native mode:
+1. FLAC__stream_decoder_process_single (frame by frame decoding)
+2. FLAC__stream_decoder_process_until_end_of_stream (decoding entire stream)
+
+One of these two decoder API's will be called based on LSB of 5th byte of data.
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the input data to the codec using a read_callback as and when
+requested by the decoder. The read_callback feeds the input data to the decoder
+until the end of stream.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build flac_dec_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+ $ mm -j$(nproc) flac_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some flac files to that folder
+Push this directory to device.
+
+To run on device
+```
+ $ adb sync data
+ $ adb shell /data/fuzz/arm64/flac_dec_fuzzer/flac_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```

+
+## Plugin Design Considerations
+The fuzzer plugin for flac encoder is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+Follwing functions were called in initEncoder to configure the encoder:

+| `FLAC__stream_encoder_set_channels` | mChannels |`1 ` `2 ` | bit 0 of 4th byte of data |
+| `FLAC__stream_encoder_set_compression_level` | compression |`1 ` `2 ` | bit 0 of 5th byte of data |

+| `FLAC__stream_encoder_set_total_samples_estimate` | - |`0 ` `1 ` | bit 0 of 19th byte of data|
+
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec and continues with the encoding even on a failure. This ensures that the plugin tolerates any kind of input (empty, huge, malformed, etc) and doesn't `exit()` on any input and thereby increasing the chance of identifying vulnerabilities.

+ * FLAC::Encoder::Stream.
+ *
+ * The usage of this class is similar to FLAC__StreamEncoder,
+ * except instead of providing callbacks to
+ * FLAC__stream_encoder_init*_FILE() or
+ * FLAC__stream_encoder_init*_file(), you will inherit from this
+ * class and override the virtual callback functions with your
+ * own implementations, then call init() or init_ogg(). The rest
+ * of the calls work the same as in the C layer.
+ *
+ * There are no mandatory callbacks; all the callbacks from
+ * FLAC::Encoder::Stream are implemented here fully and support
+ * full post-encode STREAMINFO and SEEKTABLE updating. There is
+ * only an optional progress callback which you may override to
+ * get periodic reports on the progress of the encode.

+ * \brief
+ * Level 2 metadata iterator.
+ *
+ * The flow through the iterator in the C++ layer is similar
+ * to the C layer:
+ * - Create a Chain instance
+ * - Check Chain::is_valid()
+ * - Call Chain::read() and check the return
+ * - Traverse and/or edit with an Iterator or with
+ * Chain::merge_padding() or Chain::sort_padding()
+ * - Write changes back to FLAC file with Chain::write()
+ * - Destroy the Chain instance
+ *
+ * The ownership of pointers in the C++ layer is slightly
+ * different than in the C layer, i.e.
+ * - The objects returned by Iterator::get_block() are NOT
+ * owned by the iterator and should be deleted by the
+ * caller when finished, BUT, when you modify the block,
+ * it will directly edit what's in the chain and you do
+ * not need to call Iterator::set_block(). However the
+ * changes will not be reflected in the FLAC file until
+ * the chain is written with Chain::write().
+ * - When you pass an object to Iterator::set_block(),
+ * Iterator::insert_block_before(), or
+ * Iterator::insert_block_after(), the iterator takes
+ * ownership of the block and it will be deleted by the
+ * chain.
+ *
+ * See the \link flac_metadata_level2 C layer equivalent \endlink
+ * for more.

- * This code implements the MD5 message-digest algorithm.
- * The algorithm is due to Ron Rivest. This code was

- * This code is in the public domain; do with it what you wish.
- *
- * Equivalent code is available from RSA Data Security, Inc.
- * This code has been tested against that, and is equivalent,
- * except that you don't need to include two pages of legalese
- * with every copy.
- *
- * To compute the message digest of a chunk of bytes, declare an
- * MD5Context structure, pass it to MD5Init, call MD5Update as
- * needed on buffers full of bytes, and then call MD5Final, which
- * will fill a supplied 16-byte array with the digest.
- *
- * Changed so as no longer to depend on Colin Plumb's `usual.h' header
- * definitions; now uses stuff from dpkg's config.h.
- * - Ian Jackson <ijackson@nyx.cs.du.edu>.
- * Still in the public domain.
- *
- * Josh Coalson: made some changes to integrate with libFLAC.

- * directory name belonging to a different partition in
- * 'tempfile_path_prefix'. Note that you should use the forward slash

- * but how much it asks for depends on how much free space it has in
- * its internal buffer. It does not try to grow its internal buffer
- * to accomodate a whole frame because then the internal buffer size
- * could not be limited, which is necessary in embedded applications.
- *
- * Ogg however grows its internal buffer until a whole page is present;
- * only then can you get decoded data out. So we can't just ask for
- * the same number of bytes from Ogg, then pass what's decoded down to
- * libFLAC. If what libFLAC is asking for will not contain a whole
- * page, then we will get no data from ogg_sync_pageout(), and at the
- * same time cannot just read more data from the client for the purpose
- * of getting a whole decoded page because the decoded size might be
- * larger than libFLAC's internal buffer.
- *
- * Instead, whenever this read callback wrapper is called, we will
- * continually request data from the client until we have at least one
- * page, and manage pages internally so that we can send pieces of
- * pages down to libFLAC in such a way that we obey its size
- * requirement. To limit the amount of callbacks, we will always try
- * to read in enough pages to return the full number of bytes

+# AX_ADD_FORTIFY_SOURCE
+#
+# DESCRIPTION
+#
+# Check whether -D_FORTIFY_SOURCE=2 can be added to CPPFLAGS without macro
+# redefinition warnings. Some distributions (such as Gentoo Linux) enable
+# _FORTIFY_SOURCE globally in their compilers, leading to unnecessary
+# warnings in the form of
+#
+# <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
+# <built-in>: note: this is the location of the previous definition
+#
+# which is a problem if -Werror is enabled. This macro checks whether
+# _FORTIFY_SOURCE is already defined, and if not, adds -D_FORTIFY_SOURCE=2
+# to CPPFLAGS.

+# SYNOPSIS
+#
+# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
+#
+# DESCRIPTION
+#
+# Check for the presence of an --enable-debug option to configure, with
+# the specified default value used when the option is not present. Return
+# the value in the variable $ax_enable_debug.
+#
+# Specifying 'yes' adds '-g -O0' to the compilation flags for all
+# languages. Specifying 'info' adds '-g' to the compilation flags.
+# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
+# the linking flags. Otherwise, nothing is added.
+#
+# Define the variables listed in the second argument if debug is enabled,
+# defaulting to no variables. Defines the variables listed in the third
+# argument if debug is disabled, defaulting to NDEBUG. All lists of
+# variables should be space-separated.
+#
+# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
+# Should be invoked prior to any AC_PROG_* compiler checks.
+#
+# IS-RELEASE can be used to change the default to 'no' when making a
+# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
+# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
+# macro, there is no need to pass this parameter.

+.SH "DESCRIPTION"
+.PP
+\fBflac\fR is a command-line tool for encoding, decoding, testing and analyzing FLAC streams.
+.SH "OPTIONS"
+.PP
+A summary of options is included below. For a complete
+description, see the HTML documentation.
+.SS "GENERAL OPTIONS"
+.TP
+\fB-v, --version\fR
+Show the flac version number
+.TP
+\fB-h, --help \fR
+Show basic usage and a list of all options
+.TP
+\fB-H, --explain \fR
+Show detailed explanation of usage and all options
+.TP
+\fB-d, --decode \fR
+Decode (the default behavior is to encode)
+.TP
+\fB-t, --test \fR
+Test a flac encoded file (same as -d except no decoded file is written)
+.TP
+\fB-a, --analyze \fR
+Analyze a FLAC encoded file (same as -d except an analysis file is written)
+.TP
+\fB-c, --stdout \fR
+Write output to stdout
+.TP
+\fB-s, --silent \fR
+Silent mode (do not write runtime encode/decode statistics to stderr)
+.TP
+\fB--totally-silent \fR
+Do not print anything of any kind, including warnings or errors. The exit code will be the only way to determine successful completion.
+.TP
+\fB--no-utf8-convert \fR
+Do not convert tags from local charset to UTF-8. This is useful for scripts, and setting tags in situations where the locale is wrong. This option must appear before any tag options!
+.TP
+\fB-w, --warnings-as-errors \fR
+Treat all warnings as errors (which cause flac to terminate with a non-zero exit code).
+.TP
+\fB-f, --force \fR
+Force overwriting of output files. By default, flac warns that the output file already exists and continues to the next file.
+.TP
+\fB-o \fIfilename\fB, --output-name=\fIfilename\fB\fR
+Force the output file name (usually flac just changes the extension). May only be used when encoding a single file. May not be used in conjunction with --output-prefix.
+.TP
+\fB--output-prefix=\fIstring\fB\fR
+Prefix each output file name with the given string. This can be useful for encoding or decoding files to a different directory. Make sure if your string is a path name that it ends with a trailing `/' (slash).
+.TP
+\fB--delete-input-file \fR
+Automatically delete the input file after a successful encode or decode. If there was an error (including a verify error) the input file is left intact.
+.TP
+\fB--preserve-modtime \fR
+Output files have their timestamps/permissions set to match those of their inputs (this is default). Use --no-preserve-modtime to make output files have the current time and default permissions.
+.TP
+\fB--keep-foreign-metadata \fR
+If encoding, save WAVE, RF64, or AIFF non-audio chunks in FLAC metadata. If decoding, restore any saved non-audio chunks from FLAC metadata when writing the decoded file. Foreign metadata cannot be transcoded, e.g. WAVE chunks saved in a FLAC file cannot be restored when decoding to AIFF. Input and output must be regular files (not stdin or stdout).
+.TP
+\fB--skip={\fI#\fB|\fImm:ss.ss\fB}\fR
+Skip over the first number of samples of the input. This works for both encoding and decoding, but not testing. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second.
+.TP
+\fB--until={\fI#\fB|[\fI+\fB|\fI-\fB]\fImm:ss.ss\fB}\fR
+Stop at the given sample number for each input file. This works for both encoding and decoding, but not testing. The given sample number is not included in the decoded output. The alternative form mm:ss.ss can be used to specify minutes, seconds, and fractions of a second. If a `+' (plus) sign is at the beginning, the --until point is relative to the --skip point. If a `-' (minus) sign is at the beginning, the --until point is relative to end of the audio.
+.TP
+\fB--ogg\fR
+When encoding, generate Ogg FLAC output instead of native FLAC. Ogg FLAC streams are FLAC streams wrapped in an Ogg transport layer. The resulting file should have an '.oga' extension and will still be decodable by flac.
+
+When decoding, force the input to be treated as Ogg FLAC. This is useful when piping input from stdin or when the filename does not end in '.oga' or '.ogg'.
+.TP
+\fB--serial-number=\fI#\fB\fR
+When used with --ogg, specifies the serial number to use for the first Ogg FLAC stream, which is then incremented for each additional stream. When encoding and no serial number is given, flac uses a random number for the first stream, then increments it for each additional stream. When decoding and no number is given, flac uses the serial number of the first page.
+.SS "ANALYSIS OPTIONS"
+.TP
+\fB--residual-text \fR
+Includes the residual signal in the analysis file. This will make the file very big, much larger than even the decoded file.
+.TP
+\fB--residual-gnuplot \fR
+Generates a gnuplot file for every subframe; each file will contain the residual distribution of the subframe. This will create a lot of files.
+.SS "DECODING OPTIONS"
+.TP
+\fB--cue=[\fI#.#\fB][-[\fI#.#\fB]]\fR
+Set the beginning and ending cuepoints to decode. The optional first #.# is the track and index point at which decoding will start; the default is the beginning of the stream. The optional second #.# is the track and index point at which decoding will end; the default is the end of the stream. If the cuepoint does not exist, the closest one before it (for the start point) or after it (for the end point) will be used. If those don't exist, the start of the stream (for the start point) or end of the stream (for the end point) will be used. The cuepoints are merely translated into sample numbers then used as --skip and --until. A CD track can always be cued by, for example, --cue=9.1-10.1 for track 9, even if the CD has no 10th track.
+.TP
+\fB-F, --decode-through-errors \fR
+By default flac stops decoding with an error and removes the partially decoded file if it encounters a bitstream error. With -F, errors are still printed but flac will continue decoding to completion. Note that errors may cause the decoded audio to be missing some samples or have silent sections.
+.TP
+\fB--apply-replaygain-which-is-not-lossless[=<specification>] \fR
+Applies ReplayGain values while decoding.
+
+WARNING: THIS IS NOT LOSSLESS. DECODED AUDIO WILL NOT BE IDENTICAL TO THE ORIGINAL WITH THIS OPTION.
+
+The equals sign and <specification> is optional. If omitted, the default is 0aLn1.
+
+The <specification> is a shorthand notation for describing how to apply ReplayGain. All components are optional but order is important. '[]' means 'optional'. '|' means 'or'. '{}' means required. The format is:
+
+[<preamp>][a|t][l|L][n{0|1|2|3}]
+.RS
+.TP
+\fBpreamp\fR
+A floating point number in dB. This is added to the existing gain value.
+.TP
+\fBa|t\fR
+Specify 'a' to use the album gain, or 't' to use the track gain. If tags for the preferred kind (album/track) do not exist but tags for the other (track/album) do, those will be used instead.
+.TP
+\fBl|L\fR
+Specify 'l' to peak-limit the output, so that the ReplayGain peak value is full-scale. Specify 'L' to use a 6dB hard limiter that kicks in when the signal approaches full-scale.
+.TP
+\fBn{0|1|2|3}\fR
+Specify the amount of noise shaping. ReplayGain synthesis happens in floating point; the result is dithered before converting back to integer. This quantization adds noise. Noise shaping tries to move the noise where you won't hear it as much. 0 means no noise shaping, 1 means 'low', 2 means 'medium', 3 means 'high'.
+.RE
+
+For example, the default of 0aLn1 means 0dB preamp, use album gain, 6dB hard limit, low noise shaping.
+
+--apply-replaygain-which-is-not-lossless=3 means 3dB preamp, use album gain, no limiting, no noise shaping.
+
+flac uses the ReplayGain tags for the calculation. If a stream does not have the required tags or they can't be parsed, decoding will continue with a warning, and no ReplayGain is applied to that stream.
+.SS "ENCODING OPTIONS"
+.TP
+\fB-V, --verify\fR
+Verify a correct encoding by decoding the output in parallel and comparing to the original
+.TP
+\fB--lax\fR
+Allow encoder to generate non-Subset files. The resulting FLAC file may not be streamable or might have trouble being played in all players (especially hardware devices), so you should only use this option in combination with custom encoding options meant for archival.
+.TP
+\fB--replay-gain\fR
+Calculate ReplayGain values and store them as FLAC tags, similar to vorbisgain. Title gains/peaks will be computed for each input file, and an album gain/peak will be computed for all files. All input files must have the same resolution, sample rate, and number of channels. Only mono and stereo files are allowed, and the sample rate must be one of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48 kHz. Also note that this option may leave a few extra bytes in a PADDING block as the exact size of the tags is not known until all files are processed. Note that this option cannot be used when encoding to standard output (stdout).
+.TP
+\fB--cuesheet=\fIfilename\fB\fR
+Import the given cuesheet file and store it in a CUESHEET metadata block. This option may only be used when encoding a single file. A seekpoint will be added for each index point in the cuesheet to the SEEKTABLE unless --no-cued-seekpoints is specified.
+.TP
+\fB--picture={\fIFILENAME\fB|\fISPECIFICATION\fB}\fR
+Import a picture and store it in a PICTURE metadata block. More than one --picture command can be specified. Either a filename for the picture file or a more complete specification form can be used. The SPECIFICATION is a string whose parts are separated by | (pipe) characters. Some parts may be left empty to invoke default values. FILENAME is just shorthand for "||||FILENAME". The format of SPECIFICATION is
+
+[TYPE]|[MIME-TYPE]|[DESCRIPTION]|[WIDTHxHEIGHTxDEPTH[/COLORS]]|FILE
+
+TYPE is optional; it is a number from one of:
+
+0: Other
+
+1: 32x32 pixels 'file icon' (PNG only)
+
+2: Other file icon
+
+3: Cover (front)
+
+4: Cover (back)
+
+5: Leaflet page
+
+6: Media (e.g. label side of CD)
+
+7: Lead artist/lead performer/soloist
+
+8: Artist/performer
+
+9: Conductor
+
+10: Band/Orchestra
+
+11: Composer
+
+12: Lyricist/text writer
+
+13: Recording Location
+
+14: During recording
+
+15: During performance
+
+16: Movie/video screen capture
+
+17: A bright coloured fish
+
+18: Illustration
+
+19: Band/artist logotype
+
+20: Publisher/Studio logotype
+
+The default is 3 (front cover). There may only be one picture each of type 1 and 2 in a file.
+
+MIME-TYPE is optional; if left blank, it will be detected from the file. For best compatibility with players, use pictures with MIME type image/jpeg or image/png. The MIME type can also be --> to mean that FILE is actually a URL to an image, though this use is discouraged.
+
+DESCRIPTION is optional; the default is an empty string.
+
+The next part specifies the resolution and color information. If the MIME-TYPE is image/jpeg, image/png, or image/gif, you can usually leave this empty and they can be detected from the file. Otherwise, you must specify the width in pixels, height in pixels, and color depth in bits-per-pixel. If the image has indexed colors you should also specify the number of colors used. When manually specified, it is not checked against the file for accuracy.
+
+FILE is the path to the picture file to be imported, or the URL if MIME type is -->
+
+For example, "|image/jpeg|||../cover.jpg" will embed the JPEG file at ../cover.jpg, defaulting to type 3 (front cover) and an empty description. The resolution and color info will be retrieved from the file itself.
+
+The specification "4|-->|CD|320x300x24/173|http://blah.blah/backcover.tiff" will embed the given URL, with type 4 (back cover), description "CD", and a manually specified resolution of 320x300, 24 bits-per-pixel, and 173 colors. The file at the URL will not be fetched; the URL itself is stored in the PICTURE metadata block.
+.TP
+\fB--sector-align\fR
+Align encoding of multiple CD format files on sector boundaries. See the HTML documentation for more information. This option is DEPRECATED and may not exist in future versions of flac.
+.TP
+\fB--ignore-chunk-sizes\fR
+When encoding to flac, ignore the file size headers in WAV and AIFF files to attempt to work around problems with over-sized or malformed files.
+
+WAV and AIFF files both have an unsigned 32 bit numbers in the file header which specifes the length of audio data. Since this number is unsigned 32 bits, that limits the size of a valid file to being just over 4 Gigabytes. Files larger than this are mal-formed, but should be read correctly using this option.
+.TP
+\fB-S {\fI#\fB|\fIX\fB|\fI#x\fB|\fI#s\fB}, --seekpoint={\fI#\fB|\fIX\fB|\fI#x\fB|\fI#s\fB}\fR
+Include a point or points in a SEEKTABLE. Using #, a seek point at that sample number is added. Using X, a placeholder point is added at the end of a the table. Using #x, # evenly spaced seek points will be added, the first being at sample 0. Using #s, a seekpoint will be added every # seconds (# does not have to be a whole number; it can be, for example, 9.5, meaning a seekpoint every 9.5 seconds). You may use many -S options; the resulting SEEKTABLE will be the unique-ified union of all such values. With no -S options, flac defaults to '-S 10s'. Use --no-seektable for no SEEKTABLE. Note: '-S #x' and '-S #s' will not work if the encoder can't determine the input size before starting. Note: if you use '-S #' and # is >= samples in the input, there will be either no seek point entered (if the input size is determinable before encoding starts) or a placeholder point (if input size is not determinable).
+.TP
+\fB-P \fI#\fB, --padding=\fI#\fB\fR
+Tell the encoder to write a PADDING metadata block of the given length (in bytes) after the STREAMINFO block. This is useful if you plan to tag the file later with an APPLICATION block; instead of having to rewrite the entire file later just to insert your block, you can write directly over the PADDING block. Note that the total length of the PADDING block will be 4 bytes longer than the length given because of the 4 metadata block header bytes. You can force no PADDING block at all to be written with --no-padding. The encoder writes a PADDING block of 8192 bytes by default (or 65536 bytes if the input audio stream is more that 20 minutes long).
+.TP
+\fB-T \fIFIELD=VALUE\fB, --tag=\fIFIELD=VALUE\fB\fR
+Add a FLAC tag. The comment must adhere to the Vorbis comment spec; i.e. the FIELD must contain only legal characters, terminated by an 'equals' sign. Make sure to quote the comment if necessary. This option may appear more than once to add several comments. NOTE: all tags will be added to all encoded files.
+.TP
+\fB--tag-from-file=\fIFIELD=FILENAME\fB\fR
+Like --tag, except FILENAME is a file whose contents will be read verbatim to set the tag value. The contents will be converted to UTF-8 from the local charset. This can be used to store a cuesheet in a tag (e.g. --tag-from-file="CUESHEET=image.cue"). Do not try to store binary data in tag fields! Use APPLICATION blocks for that.
+.TP
+\fB-b \fI#\fB, --blocksize=\fI#\fB\fR
+Specify the block size in samples. Subset streams must use one of 192, 576, 1152, 2304, 4608, 256, 512, 1024, 2048, 4096 (and 8192 or 16384 if the sample rate is >48kHz).
+.TP
+\fB-m, --mid-side\fR
+Try mid-side coding for each frame (stereo input only)
+.TP
+\fB-M, --adaptive-mid-side\fR
+Adaptive mid-side coding for all frames (stereo input only)
+.TP
+\fB-0\&..-8, --compression-level-0\&..--compression-level-8\fR
+Fastest compression..highest compression (default is -5). These are synonyms for other options:
+.RS
+.TP
+\fB-0, --compression-level-0\fR
+Synonymous with -l 0 -b 1152 -r 3 --no-mid-side
+.TP
+\fB-1, --compression-level-1\fR
+Synonymous with -l 0 -b 1152 -M -r 3
+.TP
+\fB-2, --compression-level-2\fR
+Synonymous with -l 0 -b 1152 -m -r 3
+.TP
+\fB-3, --compression-level-3\fR
+Synonymous with -l 6 -b 4096 -r 4 --no-mid-side
+.TP
+\fB-4, --compression-level-4\fR
+Synonymous with -l 8 -b 4096 -M -r 4
+.TP
+\fB-5, --compression-level-5\fR
+Synonymous with -l 8 -b 4096 -m -r 5
+.TP
+\fB-6, --compression-level-6\fR
+Synonymous with -l 8 -b 4096 -m -r 6 -A tukey(0.5) -A partial_tukey(2)
+.TP
+\fB-7, --compression-level-7\fR
+Synonymous with -l 12 -b 4096 -m -r 6 -A tukey(0.5) -A partial_tukey(2)
+.TP
+\fB-8, --compression-level-8\fR
+Synonymous with -l 12 -b 4096 -m -r 6 -A tukey(0.5) -A partial_tukey(2) -A punchout_tukey(3)
+.RE
+.TP
+\fB--fast\fR
+Fastest compression. Currently synonymous with -0.
+.TP
+\fB--best\fR
+Highest compression. Currently synonymous with -8.
+.TP
+\fB-e, --exhaustive-model-search\fR
+Do exhaustive model search (expensive!)
+.TP
+\fB-A \fIfunction\fB, --apodization=\fIfunction\fB\fR
+Window audio data with given the apodization function. The functions are: bartlett, bartlett_hann, blackman, blackman_harris_4term_92db, connes, flattop, gauss(STDDEV), hamming, hann, kaiser_bessel, nuttall, rectangle, triangle, tukey(P), partial_tukey(n[/ov[/P]]), punchout_tukey(n[/ov[/P]]), welch.
+
+For gauss(STDDEV), STDDEV is the standard deviation (0<STDDEV<=0.5).
+
+For tukey(P), P specifies the fraction of the window that is tapered (0<=P<=1; P=0 corresponds to "rectangle" and P=1 corresponds to "hann").
+
+For partial_tukey(n) and punchout_tukey(n), n apodization functions are added that span different parts of each block. Values of 2 to 6 seem to yield sane results. If necessary, an overlap can be specified, as can be the taper parameter, for example partial_tukey(2/0.2) or partial_tukey(2/0.2/0.5). ov should be smaller than 1 and can be negative.
+
+Please note that P, STDDEV and ov are locale specific, so a comma as decimal separator might be required instead of a dot.
+
+More than one -A option (up to 32) may be used. Any function that is specified erroneously is silently dropped. The encoder chooses suitable defaults in the absence of any -A options; any -A option specified replaces the default(s).
+
+When more than one function is specified, then for every subframe the encoder will try each of them separately and choose the window that results in the smallest compressed subframe. Multiple functions can greatly increase the encoding time.
+.TP
+\fB-l \fI#\fB, --max-lpc-order=\fI#\fB\fR
+Specifies the maximum LPC order. This number must be <= 32. For Subset streams, it must be <=12 if the sample rate is <=48kHz. If 0, the encoder will not attempt generic linear prediction, and use only fixed predictors. Using fixed predictors is faster but usually results in files being 5-10% larger.
+.TP
+\fB-p, --qlp-coeff-precision-search\fR
+Do exhaustive search of LP coefficient quantization (expensive!). Overrides -q; does nothing if using -l 0
+.TP
+\fB-q \fI#\fB, --qlp-coeff-precision=\fI#\fB\fR
+Precision of the quantized linear-predictor coefficients, 0 => let encoder decide (min is 5, default is 0)
+.TP
+\fB-r [\fI#\fB,]\fI#\fB, --rice-partition-order=[\fI#\fB,]\fI#\fB\fR
+Set the [min,]max residual partition order (0..15). min defaults to 0 if unspecified. Default is -r 5.
+.SS "FORMAT OPTIONS"
+.TP
+\fB--endian={\fIbig\fB|\fIlittle\fB}\fR
+Set the byte order for samples
+.TP
+\fB--channels=\fI#\fB\fR
+Set number of channels.
+.TP
+\fB--bps=\fI#\fB\fR
+Set bits per sample.
+.TP
+\fB--sample-rate=\fI#\fB\fR
+Set sample rate (in Hz).
+.TP
+\fB--sign={\fIsigned\fB|\fIunsigned\fB}\fR
+Set the sign of samples (the default is signed).
+.TP
+\fB--input-size=\fI#\fB\fR
+Specify the size of the raw input in bytes. If you are encoding raw samples from stdin, you must set this option in order to be able to use --skip, --until, --cuesheet, or other options that need to know the size of the input beforehand. If the size given is greater than what is found in the input stream, the encoder will complain about an unexpected end-of-file. If the size given is less, samples will be truncated.
+.TP
+\fB--force-raw-format\fR
+Force input (when encoding) or output (when decoding) to be treated as raw samples (even if filename ends in \fI\&.wav\fR).
+.TP
+\fB--force-aiff-format\fR
+Force the decoder to output AIFF format. This option is not needed if the output filename (as set by -o) ends with \fI\&.aif\fR or \fI\&.aiff\fR\&. Also, this option has no effect when encoding since input AIFF is auto-detected.
+.TP
+\fB--force-rf64-format\fR
+Force the decoder to output RF64 format. This option is not needed if the output filename (as set by -o) ends with \fI\&.rf64\fR\&. Also, this option has no effect when encoding since input RF64 is auto-detected.
+.TP
+\fB--force-wave64-format\fR
+Force the decoder to output Wave64 format. This option is not needed if the output filename (as set by -o) ends with \fI\&.w64\fR\&. Also, this option has no effect when encoding since input Wave64 is auto-detected.

+ <term><option>--cue=[<replaceable>#.#</replaceable>][-[<replaceable>#.#</replaceable>]]</option></term>
+ <listitem>
+ <para>Set the beginning and ending cuepoints to decode. The optional first #.# is the track and index point at which decoding will start; the default is the beginning of the stream. The optional second #.# is the track and index point at which decoding will end; the default is the end of the stream. If the cuepoint does not exist, the closest one before it (for the start point) or after it (for the end point) will be used. If those don't exist, the start of the stream (for the start point) or end of the stream (for the end point) will be used. The cuepoints are merely translated into sample numbers then used as --skip and --until. A CD track can always be cued by, for example, --cue=9.1-10.1 for track 9, even if the CD has no 10th track.</para>

+ <term><option>-F</option>, <option>--decode-through-errors</option>
+ </term>
+ <listitem>
+ <para>By default flac stops decoding with an error and removes the partially decoded file if it encounters a bitstream error. With -F, errors are still printed but flac will continue decoding to completion. Note that errors may cause the decoded audio to be missing some samples or have silent sections.</para>

+ <para>WARNING: THIS IS NOT LOSSLESS. DECODED AUDIO WILL NOT BE IDENTICAL TO THE ORIGINAL WITH THIS OPTION.</para>
+ <para>The equals sign and <specification> is optional. If omitted, the default is 0aLn1.</para>
+ <para>The <specification> is a shorthand notation for describing how to apply ReplayGain. All components are optional but order is important. '[]' means 'optional'. '|' means 'or'. '{}' means required. The format is:</para>

+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><option>l|L</option></term>
+ <listitem>
+ <para>Specify 'l' to peak-limit the output, so that the ReplayGain peak value is full-scale. Specify 'L' to use a 6dB hard limiter that kicks in when the signal approaches full-scale.</para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><option>n{0|1|2|3}</option></term>
+ <listitem>
+ <para>Specify the amount of noise shaping. ReplayGain synthesis happens in floating point; the result is dithered before converting back to integer. This quantization adds noise. Noise shaping tries to move the noise where you won't hear it as much. 0 means no noise shaping, 1 means 'low', 2 means 'medium', 3 means 'high'.</para>
+ </listitem>
+ </varlistentry>
+
+ </variablelist>
+
+ <para>For example, the default of 0aLn1 means 0dB preamp, use album gain, 6dB hard limit, low noise shaping.</para>
+ <para>--apply-replaygain-which-is-not-lossless=3 means 3dB preamp, use album gain, no limiting, no noise shaping.</para>
+ <para>flac uses the ReplayGain tags for the calculation. If a stream does not have the required tags or they can't be parsed, decoding will continue with a warning, and no ReplayGain is applied to that stream.</para>

+
+ <listitem>
+ <para>Calculate ReplayGain values and store them as FLAC tags, similar to vorbisgain. Title gains/peaks will be computed for each input file, and an album gain/peak will be computed for all files. All input files must have the same resolution, sample rate, and number of channels. Only mono and stereo files are allowed, and the sample rate must be one of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48 kHz. Also note that this option may leave a few extra bytes in a PADDING block as the exact size of the tags is not known until all files are processed. Note that this option cannot be used when encoding to standard output (stdout).</para>

Either a filename for the picture file or a more complete specification form can be used. The SPECIFICATION is a string whose parts are separated by | (pipe) characters. Some parts may be left empty to invoke default values. FILENAME is just shorthand for "||||FILENAME". The format of SPECIFICATION is</para>
+ <para>[TYPE]|[MIME-TYPE]|[DESCRIPTION]|[WIDTHxHEIGHTxDEPTH[/COLORS]]|FILE</para>
+ <para>TYPE is optional; it is a number from one of:</para>
+ <para>0: Other</para>
+ <para>1: 32x32 pixels 'file icon' (PNG only)</para>
+ <para>2: Other file icon</para>

+ <para>20: Publisher/Studio logotype</para>
+ <para>The default is 3 (front cover). There may only be one picture each of type 1 and 2 in a file.</para>
+
+ <para>MIME-TYPE is optional; if left blank, it will be detected from the file. For best compatibility with players, use pictures with MIME type image/jpeg or image/png. The MIME type can also be --> to mean that FILE is actually a URL to an image, though this use is discouraged.</para>
+
+ <para>DESCRIPTION is optional; the default is an empty string.</para>
+
+ <para>The next part specifies the resolution and color information. If the MIME-TYPE is image/jpeg, image/png, or image/gif, you can usually leave this empty and they can be detected from the file. Otherwise, you must specify the width in pixels, height in pixels, and color depth in bits-per-pixel. If the image has indexed colors you should also specify the number of colors used. When manually specified, it is not checked against the file for accuracy.</para>
+
+ <para>FILE is the path to the picture file to be imported, or the URL if MIME type is --></para>
+
+ <para>For example, "|image/jpeg|||../cover.jpg" will embed the JPEG file at ../cover.jpg, defaulting to type 3 (front cover) and an empty description. The resolution and color info will be retrieved from the file itself.</para>
+
+ <para>The specification "4|-->|CD|320x300x24/173|http://blah.blah/backcover.tiff" will embed the given URL, with type 4 (back cover), description "CD", and a manually specified resolution of 320x300, 24 bits-per-pixel, and 173 colors. The file at the URL will not be fetched; the URL itself is stored in the PICTURE metadata block.</para>

+
+ <listitem>
+ <para>When encoding to flac, ignore the file size headers in WAV and AIFF files to attempt to work around problems with over-sized or malformed files.</para>
+ <para>WAV and AIFF files both have an unsigned 32 bit numbers in the file header which specifes the length of audio data. Since this number is unsigned 32 bits, that limits the size of a valid file to being just over 4 Gigabytes. Files larger than this are mal-formed, but should be read correctly using this option.</para>

+
+ <listitem>
+ <para>Include a point or points in a SEEKTABLE. Using #, a seek point at that sample number is added. Using X, a placeholder point is added at the end of a the table. Using #x, # evenly spaced seek points will be added, the first being at sample 0. Using #s, a seekpoint will be added every # seconds (# does not have to be a whole number; it can be, for example, 9.5, meaning a seekpoint every 9.5 seconds). You may use many -S options; the resulting SEEKTABLE will be the unique-ified union of all such values. With no -S options, flac defaults to '-S 10s'. Use --no-seektable for no SEEKTABLE. Note: '-S #x' and '-S #s' will not work if the encoder can't determine the input size before starting. Note: if you use '-S #' and # is >= samples in the input, there will be either no seek point entered (if the input size is determinable before encoding starts) or a placeholder point (if input size is not determinable).</para>

+
+ <listitem>
+ <para>Tell the encoder to write a PADDING metadata block of the given length (in bytes) after the STREAMINFO block. This is useful if you plan to tag the file later with an APPLICATION block; instead of having to rewrite the entire file later just to insert your block, you can write directly over the PADDING block. Note that the total length of the PADDING block will be 4 bytes longer than the length given because of the 4 metadata block header bytes. You can force no PADDING block at all to be written with --no-padding. The encoder writes a PADDING block of 8192 bytes by default (or 65536 bytes if the input audio stream is more that 20 minutes long).</para>

The functions are: bartlett, bartlett_hann, blackman, blackman_harris_4term_92db, connes, flattop, gauss(STDDEV), hamming, hann, kaiser_bessel, nuttall, rectangle, triangle, tukey(P), partial_tukey(n[/ov[/P]]), punchout_tukey(n[/ov[/P]]), welch.</para>
+ <para>For gauss(STDDEV), STDDEV is the standard deviation (0<STDDEV<=0.5).</para>
+ <para>For tukey(P), P specifies the fraction of the window that is tapered (0<=P<=1; P=0 corresponds to "rectangle" and P=1 corresponds to "hann").</para>
+ <para>For partial_tukey(n) and punchout_tukey(n), n apodization functions are added that span different parts of each block. Values of 2 to 6 seem to yield sane results. If necessary, an overlap can be specified, as can be the taper parameter, for example partial_tukey(2/0.2) or partial_tukey(2/0.2/0.5). ov should be smaller than 1 and can be negative.</para>

+.TH "METAFLAC" "1" "2013/04/30" "" ""
+
+.SH NAME
+metaflac \- program to list, add, remove, or edit metadata in one or more FLAC files.
+.SH SYNOPSIS
+
+\fBmetaflac\fR [ \fB\fIoptions\fB\fR ] [ \fB\fIoperations\fB\fR ] \fB\fIFLACfile\fB\fR\fI ...\fR
+
+.SH "DESCRIPTION"
+.PP
+Use \fBmetaflac\fR to list, add, remove, or edit
+metadata in one or more FLAC files. You may perform one major operation,
+or many shorthand operations at a time.
+.SH "OPTIONS"
+.TP
+\fB--preserve-modtime\fR
+Preserve the original modification time in spite of edits.
+.TP
+\fB--with-filename\fR
+Prefix each output line with the FLAC file name (the default if
+more than one FLAC file is specified).
+.TP
+\fB--no-filename\fR
+Do not prefix each output line with the FLAC file name (the default
+if only one FLAC file is specified).
+.TP
+\fB--no-utf8-convert\fR
+Do not convert tags from UTF-8 to local charset, or vice versa. This is
+useful for scripts, and setting tags in situations where the locale is wrong.
+.TP
+\fB--dont-use-padding\fR
+By default metaflac tries to use padding where possible to avoid
+rewriting the entire file if the metadata size changes. Use this
+option to tell metaflac to not take advantage of padding this way.
+.SH "SHORTHAND OPERATIONS"
+.TP
+\fB--show-md5sum\fR
+Show the MD5 signature from the STREAMINFO block.
+.TP
+\fB--show-min-blocksize\fR
+Show the minimum block size from the STREAMINFO block.
+.TP
+\fB--show-max-blocksize\fR
+Show the maximum block size from the STREAMINFO block.
+.TP
+\fB--show-min-framesize\fR
+Show the minimum frame size from the STREAMINFO block.
+.TP
+\fB--show-max-framesize\fR
+Show the maximum frame size from the STREAMINFO block.
+.TP
+\fB--show-sample-rate\fR
+Show the sample rate from the STREAMINFO block.
+.TP
+\fB--show-channels\fR
+Show the number of channels from the STREAMINFO block.
+.TP
+\fB--show-bps\fR
+Show the # of bits per sample from the STREAMINFO block.
+.TP
+\fB--show-total-samples\fR
+Show the total # of samples from the STREAMINFO block.
+.TP
+\fB--show-vendor-tag\fR
+Show the vendor string from the VORBIS_COMMENT block.
+.TP
+\fB--show-tag=name\fR
+Show all tags where the field name matches 'name'.
+.TP
+\fB--remove-tag=name\fR
+Remove all tags whose field name is 'name'.
+.TP
+\fB--remove-first-tag=name\fR
+Remove first tag whose field name is 'name'.
+.TP
+\fB--remove-all-tags\fR
+Remove all tags, leaving only the vendor string.
+.TP
+\fB--set-tag=field\fR
+Add a tag. The field must comply with the
+Vorbis comment spec, of the form "NAME=VALUE". If there is
+currently no tag block, one will be created.
+.TP
+\fB--set-tag-from-file=field\fR
+Like --set-tag, except the VALUE is a filename whose
+contents will be read verbatim to set the tag value.
+Unless --no-utf8-convert is specified, the contents will be
+converted to UTF-8 from the local charset. This can be used
+to store a cuesheet in a tag (e.g.
+--set-tag-from-file="CUESHEET=image.cue"). Do not try to
+store binary data in tag fields! Use APPLICATION blocks for
+that.
+.TP
+\fB--import-tags-from=file\fR
+Import tags from a file. Use '-' for stdin. Each
+line should be of the form NAME=VALUE. Multi-line comments
+are currently not supported. Specify --remove-all-tags and/or
+--no-utf8-convert before --import-tags-from if necessary. If
+FILE is '-' (stdin), only one FLAC file may be specified.
+.TP
+\fB--export-tags-to=file\fR
+Export tags to a file. Use '-' for stdout. Each
+line will be of the form NAME=VALUE. Specify
+--no-utf8-convert if necessary.
+.TP
+\fB--import-cuesheet-from=file\fR
+Import a cuesheet from a file. Use '-' for stdin. Only one
+FLAC file may be specified. A seekpoint will be added for each
+index point in the cuesheet to the SEEKTABLE unless
+--no-cued-seekpoints is specified.
+.TP
+\fB--export-cuesheet-to=file\fR
+Export CUESHEET block to a cuesheet file, suitable for use by
+CD authoring software. Use '-' for stdout. Only one FLAC file
+may be specified on the command line.
+.TP
+\fB--import-picture-from={\fIFILENAME\fB|\fISPECIFICATION\fB}\fR
+Import a picture and store it in a PICTURE metadata block. More than one --import-picture-from command can be specified. Either a filename for the picture file or a more complete specification form can be used. The SPECIFICATION is a string whose parts are separated by | (pipe) characters. Some parts may be left empty to invoke default values. FILENAME is just shorthand for "||||FILENAME". The format of SPECIFICATION is
+
+[TYPE]|[MIME-TYPE]|[DESCRIPTION]|[WIDTHxHEIGHTxDEPTH[/COLORS]]|FILE
+
+TYPE is optional; it is a number from one of:
+
+0: Other
+
+1: 32x32 pixels 'file icon' (PNG only)
+
+2: Other file icon
+
+3: Cover (front)
+
+4: Cover (back)
+
+5: Leaflet page
+
+6: Media (e.g. label side of CD)
+
+7: Lead artist/lead performer/soloist
+
+8: Artist/performer
+
+9: Conductor
+
+10: Band/Orchestra
+
+11: Composer
+
+12: Lyricist/text writer
+
+13: Recording Location
+
+14: During recording
+
+15: During performance
+
+16: Movie/video screen capture
+
+17: A bright coloured fish
+
+18: Illustration
+
+19: Band/artist logotype
+
+20: Publisher/Studio logotype
+
+The default is 3 (front cover). There may only be one picture each of type 1 and 2 in a file.
+
+MIME-TYPE is optional; if left blank, it will be detected from the file. For best compatibility with players, use pictures with MIME type image/jpeg or image/png. The MIME type can also be --> to mean that FILE is actually a URL to an image, though this use is discouraged.
+
+DESCRIPTION is optional; the default is an empty string.
+
+The next part specifies the resolution and color information. If the MIME-TYPE is image/jpeg, image/png, or image/gif, you can usually leave this empty and they can be detected from the file. Otherwise, you must specify the width in pixels, height in pixels, and color depth in bits-per-pixel. If the image has indexed colors you should also specify the number of colors used. When manually specified, it is not checked against the file for accuracy.
+
+FILE is the path to the picture file to be imported, or the URL if MIME type is -->
+
+For example, "|image/jpeg|||../cover.jpg" will embed the JPEG file at ../cover.jpg, defaulting to type 3 (front cover) and an empty description. The resolution and color info will be retrieved from the file itself.
+
+The specification "4|-->|CD|320x300x24/173|http://blah.blah/backcover.tiff" will embed the given URL, with type 4 (back cover), description "CD", and a manually specified resolution of 320x300, 24 bits-per-pixel, and 173 colors. The file at the URL will not be fetched; the URL itself is stored in the PICTURE metadata block.
+.TP
+\fB--export-picture-to=file\fR
+Export PICTURE block to a file. Use '-' for stdout. Only one FLAC file may be specified on the command line. The first PICTURE block will be exported unless --export-picture-to is preceded by a --block-number=# option to specify the exact metadata block to extract. Note that the block number is the one shown by --list.
+.TP
+\fB--add-replay-gain\fR
+Calculates the title and album gains/peaks of the given FLAC
+files as if all the files were part of one album, then stores
+them as FLAC tags. The tags are the same as
+those used by vorbisgain. Existing ReplayGain tags will be
+replaced. If only one FLAC file is given, the album and title
+gains will be the same. Since this operation requires two
+passes, it is always executed last, after all other operations
+have been completed and written to disk. All FLAC files
+specified must have the same resolution, sample rate, and
+number of channels. The sample rate must be one of 8, 11.025,
+12, 16, 18.9, 22.05, 24, 28, 32, 37.8, 44.1, 48, 56, 64, 88.2,
+96, 112, 128, 144, 176.4, or 192kHz.
+.TP
+\fB--scan-replay-gain\fR
+Like --add-replay-gain, but only analyzes the files rather than
+writing them to the tags.
+.TP
+\fB--remove-replay-gain\fR
+Removes the ReplayGain tags.
+.TP
+\fB--add-seekpoint={\fI#\fB|\fIX\fB|\fI#x\fB|\fI#s\fB}\fR
+Add seek points to a SEEKTABLE block. Using #, a seek point at
+that sample number is added. Using X, a placeholder point is
+added at the end of a the table. Using #x, # evenly spaced seek
+points will be added, the first being at sample 0. Using #s, a
+seekpoint will be added every # seconds (# does not have to be a
+whole number; it can be, for example, 9.5, meaning a seekpoint
+every 9.5 seconds). If no SEEKTABLE block exists, one will be
+created. If one already exists, points will be added to the
+existing table, and any duplicates will be turned into placeholder
+points. You may use many --add-seekpoint options; the resulting
+SEEKTABLE will be the unique-ified union of all such values.
+Example: --add-seekpoint=100x --add-seekpoint=3.5s will add 100
+evenly spaced seekpoints and a seekpoint every 3.5 seconds.
+.TP
+\fB--add-padding=length\fR
+Add a padding block of the given length (in bytes). The overall
+length of the new block will be 4 + length; the extra 4 bytes is
+for the metadata block header.
+.SH "MAJOR OPERATIONS"
+.TP
+\fB--list\fR
+List the contents of one or more metadata blocks to stdout. By
+default, all metadata blocks are listed in text format. Use the
+following options to change this behavior:
+.RS
+.TP
+\fB--block-number=#[,#[...]]\fR
+An optional comma-separated list of block numbers to display.
+The first block, the STREAMINFO block, is block 0.
+.TP
+\fB--block-type=type[,type[...]]\fR
+.TP
+\fB--except-block-type=type[,type[...]]\fR
+An optional comma-separated list of block types to be included
+or ignored with this option. Use only one of --block-type or
+--except-block-type. The valid block types are: STREAMINFO,
+PADDING, APPLICATION, SEEKTABLE, VORBIS_COMMENT, PICTURE. You
+may narrow down the types of APPLICATION blocks displayed as
+follows:
+
+APPLICATION:abcd The APPLICATION block(s) whose textual repre-
+sentation of the 4-byte ID is "abcd"
+APPLICATION:0xXXXXXXXX The APPLICATION block(s) whose hexadecimal big-
+endian representation of the 4-byte ID is
+"0xXXXXXXXX". For the example "abcd" above the
+hexadecimal equivalalent is 0x61626364
+.sp
+.RS
+.B "Note:"
+if both --block-number and --[except-]block-type are
+specified, the result is the logical AND of both
+arguments.
+.RE
+.TP
+\fB--application-data-format=hexdump|text\fR
+If the application block you are displaying contains binary
+data but your --data-format=text, you can display a hex dump
+of the application data contents instead using
+--application-data-format=hexdump.
+.RE
+.TP
+\fB--remove\fR
+Remove one or more metadata blocks from the metadata. Unless
+--dont-use-padding is specified, the blocks will be replaced with
+padding. You may not remove the STREAMINFO block.
+.RS
+.TP
+\fB--block-number=#[,#[...]]\fR
+.TP
+\fB--block-type=type[,type[...]]\fR
+.TP
+\fB--except-block-type=type[,type[...]]\fR
+See --list above for usage.
+.sp
+.RS
+.B "Note:"
+if both --block-number and --[except-]block-type are
+specified, the result is the logical AND of both arguments.
+.RE
+.RE
+.TP
+\fB--remove-all\fR
+Remove all metadata blocks (except the STREAMINFO block) from the
+metadata. Unless --dont-use-padding is specified, the blocks will
+be replaced with padding.
+.TP
+\fB--merge-padding\fR
+Merge adjacent PADDING blocks into single blocks.
+.TP
+\fB--sort-padding\fR
+Move all PADDING blocks to the end of the metadata and merge them
+into a single block.

+ * This code implements the MD5 message-digest algorithm.
+ * The algorithm is due to Ron Rivest. This code was
+ * written by Colin Plumb in 1993, no copyright is claimed.
+ * This code is in the public domain; do with it what you wish.
+ *
+ * Equivalent code is available from RSA Data Security, Inc.
+ * This code has been tested against that, and is equivalent,
+ * except that you don't need to include two pages of legalese
+ * with every copy.
+ *
+ * To compute the message digest of a chunk of bytes, declare an
+ * MD5Context structure, pass it to MD5Init, call MD5Update as
+ * needed on buffers full of bytes, and then call MD5Final, which
+ * will fill a supplied 16-byte array with the digest.
+ *
+ * Changed so as no longer to depend on Colin Plumb's `usual.h' header
+ * definitions; now uses stuff from dpkg's config.h.
+ * - Ian Jackson <ijackson@nyx.cs.du.edu>.
+ * Still in the public domain.
+ *
+ * Josh Coalson: made some changes to integrate with libFLAC.

+ given in OPTSTRING.
+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If `share__getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `share__getopt' finds another option character, it returns that character,
+ updating `share__optind' and `nextchar' so that the next call to `share__getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `share__getopt' returns -1.
+ Then `share__optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `share__opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `share__optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `share__optarg', otherwise `share__optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `share__getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct share__option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+ long-named options. */

+/*
+ * Here's the deal. Call
+ *
+ * InitGainAnalysis ( long samplefreq );
+ *
+ * to initialize everything. Call
+ *
+ * AnalyzeSamples ( const flac_float_t* left_samples,
+ * const flac_float_t* right_samples,
+ * size_t num_samples,
+ * int num_channels );
+ *
+ * as many times as you want, with as many or as few samples as you want.
+ * If mono, pass the sample buffer in through left_samples, leave
+ * right_samples NULL, and make sure num_channels = 1.
+ *
+ * GetTitleGain()
+ *
+ * will return the recommended dB level change for all samples analyzed
+ * SINCE THE LAST TIME you called GetTitleGain() OR InitGainAnalysis().
+ *
+ * GetAlbumGain()
+ *
+ * will return the recommended dB level change for all samples analyzed
+ * since InitGainAnalysis() was called and finalized with GetTitleGain().
+ *
+ * Pseudo-code to process an album:
+ *
+ * flac_float_t l_samples [4096];
+ * flac_float_t r_samples [4096];
+ * size_t num_samples;
+ * uint32_t num_songs;
+ * uint32_t i;
+ *
+ * InitGainAnalysis ( 44100 );
+ * for ( i = 1; i <= num_songs; i++ ) {
+ * while ( ( num_samples = getSongSamples ( song[i], left_samples, right_samples ) ) > 0 )
+ * AnalyzeSamples ( left_samples, right_samples, num_samples, 2 );
+ * fprintf ("Recommended dB change for song %2d: %+6.2f dB\n", i, GetTitleGain() );
+ * }
+ * fprintf ("Recommended dB change for whole album: %+6.2f dB\n", GetAlbumGain() );
+ */
+
+/*
+ * So here's the main source of potential code confusion:
+ *
+ * The filters applied to the incoming samples are IIR filters,
+ * meaning they rely on up to <filter order> number of previous samples
+ * AND up to <filter order> number of previous filtered samples.
+ *
+ * I set up the AnalyzeSamples routine to minimize memory usage and interface
+ * complexity. The speed isn't compromised too much (I don't think), but the
+ * internal complexity is higher than it should be for such a relatively
+ * simple routine.
+ *
+ * Optimization/clarity suggestions are welcome.
