-Installation Instructions

-
-Basic Installation
-==================
-
- Briefly, the shell command `./configure && make && make install'
-should configure, build, and install this package. The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package. Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below. The lack of an optional feature in a given package is not
-necessarily a bug. More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
- The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system.
-
- Running `configure' might take a while. While running, it prints
- some messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package, generally using the just-built uninstalled binaries.
-
- 4. Type `make install' to install the programs and any data files and
- documentation. When installing into a prefix owned by root, it is
- recommended that the package be configured and built as a regular
- user, and only the `make install' phase executed with root
- privileges.
-
- 5. Optionally, type `make installcheck' to repeat any self-tests, but
- this time using the binaries in their final installed location.
- This target does not install anything. Running this target as a
- regular user, particularly if the prior `make install' required
- root privileges, verifies that the installation completed
- correctly.
-
- 6. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
- 7. Often, you can also type `make uninstall' to remove the installed
- files again. In practice, not all packages have tested that
- uninstallation works correctly, even though it is required by the
- GNU Coding Standards.
-
- 8. Some packages, particularly those that use Automake, provide `make
- distcheck', which can by used by developers to test that all other
- targets like `make install' and `make uninstall' work correctly.
- This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you can use GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'. This
-is known as a "VPATH" build.
-
- With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory. After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
- On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor. Like
-this:
-
- ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CPP="gcc -E" CXXCPP="g++ -E"
-
- This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
- By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them. In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
- The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
- The first method involves providing an override variable for each
-affected directory. For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'. Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated. The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
- The second method involves providing the `DESTDIR' variable. For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names. The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters. On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
- Some packages offer the ability to configure how verbose the
-execution of `make' will be. For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
- On HP-UX, the default C compiler is not ANSI C compatible. If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
- ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
- HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved. Use GNU `make'
-instead.
-
- On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file. The option `-nodtk' can be used as
-a workaround. If GNU CC is not installed, it is therefore recommended
-to try
-
- ./configure CC="cc"
-
-and if that doesn't work, try
-
- ./configure CC="cc -nodtk"
-
- On Solaris, don't put `/usr/ucb' early in your `PATH'. This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
- On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'. It is recommended to use the following options:
-
- ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on. Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS
- KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
- Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf limitation. Until the limitation is lifted, you can use
-this workaround:
-
- CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
- Print a summary of the options unique to this package's
- `configure', and exit. The `short' variant lists options used
- only in the top level, while the `recursive' variant lists options
- also present in any nested packages.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`--prefix=DIR'
- Use DIR as the installation prefix. *note Installation Names::
- for more details, including other options available for fine-tuning
- the installation locations.
-
-`--no-create'
-`-n'
- Run the configure checks, but stop before creating any output
- files.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

+To build this source code, simply type:
+
+% make
+
+If this does not work, or if you want to change the default configuration
+(e.g., to compile for a fixed-point architecture), simply edit the options
+in the Makefile.
+
+An up-to-date implementation conforming to this standard is available in a
+Git repository at https://git.xiph.org/opus.git or on a website at:
+https://opus-codec.org/
+However, although that implementation is expected to remain conformant
+with the standard, it is the code in this RFC that shall remain normative.
+To build from the git repository instead of using this RFC, follow these
+steps:
+
+1) Clone the repository (latest implementation of this standard at the time
+of publication)
+
+% git clone https://git.xiph.org/opus.git
+% cd opus
+
+2) Compile
+
+% ./autogen.sh
+% ./configure
+% make
+
+Once you have compiled the codec, there will be a opus_demo executable in
+the top directory.
+
+Usage: opus_demo [-e] <application> <sampling rate (Hz)> <channels (1/2)>
+ <bits per second> [options] <input> <output>
+ opus_demo -d <sampling rate (Hz)> <channels (1/2)> [options]
+ <input> <output>
+
+mode: voip | audio | restricted-lowdelay
+options:
+-e : only runs the encoder (output the bit-stream)
+-d : only runs the decoder (reads the bit-stream as input)
+-cbr : enable constant bitrate; default: variable bitrate
+-cvbr : enable constrained variable bitrate; default: unconstrained
+-bandwidth <NB|MB|WB|SWB|FB> : audio bandwidth (from narrowband to fullband);
+ default: sampling rate
+-framesize <2.5|5|10|20|40|60> : frame size in ms; default: 20
+-max_payload <bytes> : maximum payload size in bytes, default: 1024
+-complexity <comp> : complexity, 0 (lowest) ... 10 (highest); default: 10
+-inbandfec : enable SILK inband FEC
+-forcemono : force mono encoding, even for stereo input
+-dtx : enable SILK DTX
+-loss <perc> : simulate packet loss, in percent (0-100); default: 0
+
+input and output are little endian signed 16-bit PCM files or opus bitstreams
+with simple opus_demo proprietary framing.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:

-Please tell bug-automake@gnu.org about your system, including the value

+This document defines the Ogg encapsulation for the Opus interactive speech and
+ audio codec.
+This allows data encoded in the Opus format to be stored in an Ogg logical
+ bitstream.

+<section anchor="intro" title="Introduction">
+<t>
+The IETF Opus codec is a low-latency audio codec optimized for both voice and
+ general-purpose audio.
+See <xref target="RFC6716"/> for technical details.
+This document defines the encapsulation of Opus in a continuous, logical Ogg
+ bitstream <xref target="RFC3533"/>.
+Ogg encapsulation provides Opus with a long-term storage format supporting
+ all of the essential features, including metadata, fast and accurate seeking,
+ corruption detection, recapture after errors, low overhead, and the ability to
+ multiplex Opus with other codecs (including video) with minimal buffering.
+It also provides a live streamable format, capable of delivery over a reliable
+ stream-oriented transport, without requiring all the data, or even the total
+ length of the data, up-front, in a form that is identical to the on-disk
+ storage format.
+</t>
+<t>
+Ogg bitstreams are made up of a series of 'pages', each of which contains data
+ from one or more 'packets'.
+Pages are the fundamental unit of multiplexing in an Ogg stream.
+Each page is associated with a particular logical stream and contains a capture
+ pattern and checksum, flags to mark the beginning and end of the logical
+ stream, and a 'granule position' that represents an absolute position in the
+ stream, to aid seeking.
+A single page can contain up to 65,025 octets of packet data from up to 255
+ different packets.
+Packets can be split arbitrarily across pages, and continued from one page to
+ the next (allowing packets much larger than would fit on a single page).
+Each page contains 'lacing values' that indicate how the data is partitioned
+ into packets, allowing a demultiplexer (demuxer) to recover the packet
+ boundaries without examining the encoded data.
+A packet is said to 'complete' on a page when the page contains the final
+ lacing value corresponding to that packet.
+</t>
+<t>
+This encapsulation defines the contents of the packet data, including
+ the necessary headers, the organization of those packets into a logical
+ stream, and the interpretation of the codec-specific granule position field.
+It does not attempt to describe or specify the existing Ogg container format.
+Readers unfamiliar with the basic concepts mentioned above are encouraged to
+ review the details in <xref target="RFC3533"/>.

+</figure>
+
+<t>
+There are two mandatory header packets.
+The first packet in the logical Ogg bitstream MUST contain the identification
+ (ID) header, which uniquely identifies a stream as Opus audio.
+The format of this header is defined in <xref target="id_header"/>.
+It is placed alone (without any other packet data) on the first page of
+ the logical Ogg bitstream, and completes on that page.
+This page has its 'beginning of stream' flag set.
+</t>
+<t>
+The second packet in the logical Ogg bitstream MUST contain the comment header,
+ which contains user-supplied metadata.
+The format of this header is defined in <xref target="comment_header"/>.
+It MAY span multiple pages, beginning on the second page of the logical
+ stream.
+However many pages it spans, the comment header packet MUST finish the page on
+ which it completes.
+</t>
+<t>
+All subsequent pages are audio data pages, and the Ogg packets they contain are
+ audio data packets.
+Each audio data packet contains one Opus packet for each of N different
+ streams, where N is typically one for mono or stereo, but MAY be greater than
+ one for multichannel audio.
+The value N is specified in the ID header (see
+ <xref target="channel_mapping"/>), and is fixed over the entire length of the
+ logical Ogg bitstream.
+</t>
+<t>
+The first (N - 1) Opus packets, if any, are packed one after another
+ into the Ogg packet, using the self-delimiting framing from Appendix B of
+ <xref target="RFC6716"/>.
+The remaining Opus packet is packed at the end of the Ogg packet using the
+ regular, undelimited framing from Section 3 of <xref target="RFC6716"/>.
+All of the Opus packets in a single Ogg packet MUST be constrained to have the
+ same duration.
+An implementation of this specification SHOULD treat any Opus packet whose
+ duration is different from that of the first Opus packet in an Ogg packet as
+ if it were a malformed Opus packet with an invalid Table Of Contents (TOC)
+ sequence.
+</t>
+<t>
+The TOC sequence at the beginning of each Opus packet indicates the coding
+ mode, audio bandwidth, channel count, duration (frame size), and number of
+ frames per packet, as described in Section 3.1
+ of <xref target="RFC6716"/>.
+The coding mode is one of SILK, Hybrid, or Constrained Energy Lapped Transform
+ (CELT).
+The combination of coding mode, audio bandwidth, and frame size is referred to
+ as the configuration of an Opus packet.
+</t>
+<t>
+Packets are placed into Ogg pages in order until the end of stream.
+Audio data packets might span page boundaries.
+The first audio data page could have the 'continued packet' flag set
+ (indicating the first audio data packet is continued from a previous page) if,
+ for example, it was a live stream joined mid-broadcast, with the headers
+ pasted on the front.
+If a page has the 'continued packet' flag set and one of the following
+ conditions is also true:
+<list style="symbols">
+<t>the previous page with packet data does not end in a continued packet (does
+ not end with a lacing value of 255) OR</t>
+<t>the page sequence numbers are not consecutive,</t>
+</list>
+ then a demuxer MUST NOT attempt to decode the data for the first packet on the
+ page unless the demuxer has some special knowledge that would allow it to
+ interpret this data despite the missing pieces.
+An implementation MUST treat a zero-octet audio data packet as if it were a
+ malformed Opus packet as described in
+ Section 3.4 of <xref target="RFC6716"/>.
+</t>
+<t>
+A logical stream ends with a page with the 'end of stream' flag set, but
+ implementations need to be prepared to deal with truncated streams that do not
+ have a page marked 'end of stream'.
+There is no reason for the final packet on the last page to be a continued
+ packet, i.e., for the final lacing value to be 255.
+However, demuxers might encounter such streams, possibly as the result of a
+ transfer that did not complete or of corruption.
+If a packet continues onto a subsequent page (i.e., when the page ends with a
+ lacing value of 255) and one of the following conditions is also true:
+<list style="symbols">
+<t>the next page with packet data does not have the 'continued packet' flag
+ set OR</t>
+<t>there is no next page with packet data OR</t>
+<t>the page sequence numbers are not consecutive,</t>
+</list>
+ then a demuxer MUST NOT attempt to decode the data from that packet unless the
+ demuxer has some special knowledge that would allow it to interpret this data
+ despite the missing pieces.
+There MUST NOT be any more pages in an Opus logical bitstream after a page
+ marked 'end of stream'.
+</t>
+</section>
+
+<section anchor="granpos" title="Granule Position">
+<t>
+The granule position MUST be zero for the ID header page and the
+ page where the comment header completes.
+That is, the first page in the logical stream, and the last header
+ page before the first audio data page both have a granule position of zero.
+</t>
+<t>
+The granule position of an audio data page encodes the total number of PCM
+ samples in the stream up to and including the last fully-decodable sample from
+ the last packet completed on that page.
+The granule position of the first audio data page will usually be larger than
+ zero, as described in <xref target="start_granpos_restrictions"/>.
+</t>
+
+<t>
+A page that is entirely spanned by a single packet (that completes on a
+ subsequent page) has no granule position, and the granule position field is
+ set to the special value '-1' in two's complement.
+</t>
+
+<t>
+The granule position of an audio data page is in units of PCM audio samples at
+ a fixed rate of 48 kHz (per channel; a stereo stream's granule position
+ does not increment at twice the speed of a mono stream).
+It is possible to run an Opus decoder at other sampling rates,
+ but all Opus packets encode samples at a sampling rate that evenly divides
+ 48 kHz.
+Therefore, the value in the granule position field always counts samples
+ assuming a 48 kHz decoding rate, and the rest of this specification makes
+ the same assumption.
+</t>
+
+<t>
+The duration of an Opus packet as defined in <xref target="RFC6716"/> can be
+ any multiple of 2.5 ms, up to a maximum of 120 ms.
+This duration is encoded in the TOC sequence at the beginning of each packet.
+The number of samples returned by a decoder corresponds to this duration
+ exactly, even for the first few packets.
+For example, a 20 ms packet fed to a decoder running at 48 kHz will
+ always return 960 samples.
+A demuxer can parse the TOC sequence at the beginning of each Ogg packet to
+ work backwards or forwards from a packet with a known granule position (i.e.,
+ the last packet completed on some page) in order to assign granule positions
+ to every packet, or even every individual sample.
+The one exception is the last page in the stream, as described below.
+</t>
+
+<t>
+All other pages with completed packets after the first MUST have a granule
+ position equal to the number of samples contained in packets that complete on
+ that page plus the granule position of the most recent page with completed
+ packets.
+This guarantees that a demuxer can assign individual packets the same granule
+ position when working forwards as when working backwards.
+For this to work, there cannot be any gaps.
+</t>
+
+<section anchor="gap-repair" title="Repairing Gaps in Real-time Streams">
+<t>
+In order to support capturing a real-time stream that has lost or not
+ transmitted packets, a multiplexer (muxer) SHOULD emit packets that explicitly
+ request the use of Packet Loss Concealment (PLC) in place of the missing
+ packets.
+Implementations that fail to do so still MUST NOT increment the granule
+ position for a page by anything other than the number of samples contained in
+ packets that actually complete on that page.
+</t>
+<t>
+Only gaps that are a multiple of 2.5 ms are repairable, as these are the
+ only durations that can be created by packet loss or discontinuous
+ transmission.
+Muxers need not handle other gap sizes.
+Creating the necessary packets involves synthesizing a TOC byte (defined in
+Section 3.1 of <xref target="RFC6716"/>)—and whatever
+ additional internal framing is needed—to indicate the packet duration
+ for each stream.
+The actual length of each missing Opus frame inside the packet is zero bytes,
+ as defined in Section 3.2.1 of <xref target="RFC6716"/>.
+</t>
+
+<t>
+Zero-byte frames MAY be packed into packets using any of codes 0, 1,
+ 2, or 3.
+When successive frames have the same configuration, the higher code packings
+ reduce overhead.
+Likewise, if the TOC configuration matches, the muxer MAY further combine the
+ empty frames with previous or subsequent non-zero-length frames (using
+ code 2 or VBR code 3).
+</t>
+
+<t>
+<xref target="RFC6716"/> does not impose any requirements on the PLC, but this
+ section outlines choices that are expected to have a positive influence on
+ most PLC implementations, including the reference implementation.
+Synthesized TOC sequences SHOULD maintain the same mode, audio bandwidth,
+ channel count, and frame size as the previous packet (if any).
+This is the simplest and usually the most well-tested case for the PLC to
+ handle and it covers all losses that do not include a configuration switch,
+ as defined in Section 4.5 of <xref target="RFC6716"/>.
+</t>
+
+<t>
+When a previous packet is available, keeping the audio bandwidth and channel
+ count the same allows the PLC to provide maximum continuity in the concealment
+ data it generates.
+However, if the size of the gap is not a multiple of the most recent frame
+ size, then the frame size will have to change for at least some frames.
+Such changes SHOULD be delayed as long as possible to simplify
+ things for PLC implementations.
+</t>
+
+<t>
+As an example, a 95 ms gap could be encoded as nineteen 5 ms frames
+ in two bytes with a single CBR code 3 packet.
+If the previous frame size was 20 ms, using four 20 ms frames
+ followed by three 5 ms frames requires 4 bytes (plus an extra byte
+ of Ogg lacing overhead), but allows the PLC to use its well-tested steady
+ state behavior for as long as possible.
+The total bitrate of the latter approach, including Ogg overhead, is about
+ 0.4 kbps, so the impact on file size is minimal.
+</t>
+
+<t>
+Changing modes is discouraged, since this causes some decoder implementations
+ to reset their PLC state.
+However, SILK and Hybrid mode frames cannot fill gaps that are not a multiple
+ of 10 ms.
+If switching to CELT mode is needed to match the gap size, a muxer SHOULD do
+ so at the end of the gap to allow the PLC to function for as long as possible.
+</t>
+
+<t>
+In the example above, if the previous frame was a 20 ms SILK mode frame,
+ the better solution is to synthesize a packet describing four 20 ms SILK
+ frames, followed by a packet with a single 10 ms SILK
+ frame, and finally a packet with a 5 ms CELT frame, to fill the 95 ms
+ gap.
+This also requires four bytes to describe the synthesized packet data (two
+ bytes for a CBR code 3 and one byte each for two code 0 packets) but three
+ bytes of Ogg lacing overhead are needed to mark the packet boundaries.
+At 0.6 kbps, this is still a minimal bitrate impact over a naive, low quality
+ solution.
+</t>
+
+<t>
+Since medium-band audio is an option only in the SILK mode, wideband frames
+ SHOULD be generated if switching from that configuration to CELT mode, to
+ ensure that any PLC implementation which does try to migrate state between
+ the modes will be able to preserve all of the available audio bandwidth.
+</t>
+
+</section>
+
+<section anchor="preskip" title="Pre-skip">
+<t>
+There is some amount of latency introduced during the decoding process, to
+ allow for overlap in the CELT mode, stereo mixing in the SILK mode, and
+ resampling.
+The encoder might have introduced additional latency through its own resampling
+ and analysis (though the exact amount is not specified).
+Therefore, the first few samples produced by the decoder do not correspond to
+ real input audio, but are instead composed of padding inserted by the encoder
+ to compensate for this latency.
+These samples need to be stored and decoded, as Opus is an asymptotically
+ convergent predictive codec, meaning the decoded contents of each frame depend
+ on the recent history of decoder inputs.
+However, a player will want to skip these samples after decoding them.
+</t>
+
+<t>
+A 'pre-skip' field in the ID header (see <xref target="id_header"/>) signals
+ the number of samples that SHOULD be skipped (decoded but discarded) at the
+ beginning of the stream, though some specific applications might have a reason
+ for looking at that data.
+This amount need not be a multiple of 2.5 ms, MAY be smaller than a single
+ packet, or MAY span the contents of several packets.
+These samples are not valid audio.
+</t>
+
+<t>
+For example, if the first Opus frame uses the CELT mode, it will always
+ produce 120 samples of windowed overlap-add data.
+However, the overlap data is initially all zeros (since there is no prior
+ frame), meaning this cannot, in general, accurately represent the original
+ audio.
+The SILK mode requires additional delay to account for its analysis and
+ resampling latency.
+The encoder delays the original audio to avoid this problem.
+</t>
+
+<t>
+The pre-skip field MAY also be used to perform sample-accurate cropping of
+ already encoded streams.
+In this case, a value of at least 3840 samples (80 ms) provides
+ sufficient history to the decoder that it will have converged
+ before the stream's output begins.

+The initial PCM sample position before any samples are played is normally '0'.

+Vorbis streams use a granule position smaller than the number of audio samples

+However, to do so, Vorbis requires that the first audio data page contains
+ exactly two packets, in order to allow the decoder to perform PCM position
+ adjustments before needing to return any PCM data.
+Opus uses the pre-skip mechanism for this purpose instead, since the encoder

+The granule position of the most recent audio data page with completed packets

+The granule position of the first audio data page with a completed packet MAY

+Allowing a granule position larger than the number of samples allows the

+ rewriting the granule position of all the remaining pages.
+This means that the PCM sample position just before the first sample to be
+ played MAY be larger than '0'.
+Synchronization when multiplexing with other logical streams still uses the PCM
+ sample position relative to '0' to compute sample times.
+This does not affect the behavior of pre-skip: exactly 'pre-skip' samples
+ SHOULD be skipped from the beginning of the decoded output, even if the
+ initial PCM sample position is greater than zero.
+</t>
+
+<t>
+On the other hand, a granule position that is smaller than the number of
+ decoded samples prevents a demuxer from working backwards to assign each
+ packet or each individual sample a valid granule position, since granule
+ positions are non-negative.
+An implementation MUST treat any stream as invalid if the granule position
+ is smaller than the number of samples contained in packets that complete on
+ the first audio data page with a completed packet, unless that page has the
+ 'end of stream' flag set.
+It MAY defer this action until it decodes the last packet completed on that

+</t>
+
+<t>
+If that page has the 'end of stream' flag set, a demuxer MUST treat any stream
+ as invalid if its granule position is smaller than the 'pre-skip' amount.
+This would indicate that there are more samples to be skipped from the initial
+ decoded output than exist in the stream.
+If the granule position is smaller than the number of decoded samples produced
+ by the packets that complete on that page, then a demuxer MUST use an initial
+ granule position of '0', and can work forwards from '0' to timestamp
+ individual packets.
+If the granule position is larger than the number of decoded samples available,
+ then the demuxer MUST still work backwards as described above, even if the

+The version number MUST always be '1' for this version of the encapsulation

+Implementations SHOULD treat streams where the upper four bits of the version
+ number match that of a recognized specification as backwards-compatible with
+ that specification.
+That is, the version number can be split into "major" and "minor" version
+ sub-fields, with changes to the "minor" sub-field (in the lower four bits)
+ signaling compatible changes.
+For example, an implementation of this specification SHOULD accept any stream
+ with a version number of '15' or less, and SHOULD assume any stream with a
+ version number '16' or greater is incompatible.
+The initial version '1' was chosen to keep implementations from relying on this
+ octet as a null terminator for the "OpusHead" string.
+<vspace blankLines="1"/>
+</t>
+<t>Output Channel Count 'C' (8 bits, unsigned):
+<vspace blankLines="1"/>
+This is the number of output channels.
+This might be different than the number of encoded channels, which can change
+ on a packet-by-packet basis.
+This value MUST NOT be zero.
+The maximum allowable value depends on the channel mapping family, and might be
+ as large as 255.
+See <xref target="channel_mapping"/> for details.
+<vspace blankLines="1"/>
+</t>
+<t>Pre-skip (16 bits, unsigned, little
+ endian):
+<vspace blankLines="1"/>
+This is the number of samples (at 48 kHz) to discard from the decoder
+ output when starting playback, and also the number to subtract from a page's
+ granule position to calculate its PCM sample position.
+When cropping the beginning of existing Ogg Opus streams, a pre-skip of at
+ least 3,840 samples (80 ms) is RECOMMENDED to ensure complete
+ convergence in the decoder.
+<vspace blankLines="1"/>

+<t>Input Sample Rate (32 bits, unsigned, little
+ endian):
+<vspace blankLines="1"/>
+This is the sample rate of the original input (before encoding), in Hz.
+This field is <spanx style="emph">not</spanx> the sample rate to use for
+ playback of the encoded data.
+<vspace blankLines="1"/>
+Opus can switch between internal audio bandwidths of 4, 6, 8, 12, and
+ 20 kHz.
+Each packet in the stream can have a different audio bandwidth.
+Regardless of the audio bandwidth, the reference decoder supports decoding any
+ stream at a sample rate of 8, 12, 16, 24, or 48 kHz.
+The original sample rate of the audio passed to the encoder is not preserved
+ by the lossy compression.
+<vspace blankLines="1"/>
+An Ogg Opus player SHOULD select the playback sample rate according to the
+ following procedure:
+<list style="numbers">
+<t>If the hardware supports 48 kHz playback, decode at 48 kHz.</t>
+<t>Otherwise, if the hardware's highest available sample rate is a supported
+ rate, decode at this sample rate.</t>
+<t>Otherwise, if the hardware's highest available sample rate is less than
+ 48 kHz, decode at the next higher Opus supported rate above the highest
+ available hardware rate and resample.</t>
+<t>Otherwise, decode at 48 kHz and resample.</t>
+</list>
+However, the 'Input Sample Rate' field allows the muxer to pass the sample
+ rate of the original input stream as metadata.
+This is useful when the user requires the output sample rate to match the
+ input sample rate.
+For example, when not playing the output, an implementation writing PCM format
+ samples to disk might choose to resample the audio back to the original input
+ sample rate to reduce surprise to the user, who might reasonably expect to get
+ back a file with the same sample rate.
+<vspace blankLines="1"/>
+A value of zero indicates 'unspecified'.
+Muxers SHOULD write the actual input sample rate or zero, but implementations
+ which do something with this field SHOULD take care to behave sanely if given
+ crazy values (e.g., do not actually upsample the output to 10 MHz if
+ requested).
+Implementations SHOULD support input sample rates between 8 kHz and
+ 192 kHz (inclusive).
+Rates outside this range MAY be ignored by falling back to the default rate of
+ 48 kHz instead.
+<vspace blankLines="1"/>
+</t>
+<t>Output Gain (16 bits, signed, little endian):
+<vspace blankLines="1"/>
+This is a gain to be applied when decoding.
+It is 20*log10 of the factor by which to scale the decoder output to achieve
+ the desired playback volume, stored in a 16-bit, signed, two's complement
+ fixed-point value with 8 fractional bits (i.e.,
+ Q7.8 <xref target="q-notation"/>).
+<vspace blankLines="1"/>
+To apply the gain, an implementation could use
+<figure align="center">
+<artwork align="center"><![CDATA[
+sample *= pow(10, output_gain/(20.0*256)) ,
+]]></artwork>
+</figure>
+ where output_gain is the raw 16-bit value from the header.
+<vspace blankLines="1"/>
+Players and media frameworks SHOULD apply it by default.
+If a player chooses to apply any volume adjustment or gain modification, such
+ as the R128_TRACK_GAIN (see <xref target="comment_header"/>), the adjustment
+ MUST be applied in addition to this output gain in order to achieve playback
+ at the normalized volume.
+<vspace blankLines="1"/>
+A muxer SHOULD set this field to zero, and instead apply any gain prior to
+ encoding, when this is possible and does not conflict with the user's wishes.
+A nonzero output gain indicates the gain was adjusted after encoding, or that
+ a user wished to adjust the gain for playback while preserving the ability
+ to recover the original signal amplitude.
+<vspace blankLines="1"/>
+Although the output gain has enormous range (+/- 128 dB, enough to amplify
+ inaudible sounds to the threshold of physical pain), most applications can
+ only reasonably use a small portion of this range around zero.
+The large range serves in part to ensure that gain can always be losslessly
+ transferred between OpusHead and R128 gain tags (see below) without
+ saturating.

+The comment header can be arbitrarily large and might be spread over a large

+<t>Second, an optional gain for album normalization:</t>
+<figure align="center">

+</figure>
+<t>
+ representing the volume shift needed to normalize the overall volume when

+The gain is also a Q7.8 fixed point number in dB, as in the ID header's
+ 'output gain' field.
+The values '-573' and '111' given here are just examples.
+</t>
+<t>
+An Ogg Opus stream MUST NOT have more than one of each of these tags, and if
+ present their values MUST be an integer from -32768 to 32767, inclusive,
+ represented in ASCII as a base 10 number with no whitespace.
+A leading '+' or '-' character is valid.
+Leading zeros are also permitted, but the value MUST be represented by
+ no more than 6 characters.
+Other non-digit characters MUST NOT be present.
+</t>
+<t>
+If present, R128_TRACK_GAIN and R128_ALBUM_GAIN MUST correctly represent
+ the R128 normalization gain relative to the 'output gain' field specified
+ in the ID header.
+If a player chooses to make use of the R128_TRACK_GAIN tag or the
+ R128_ALBUM_GAIN tag, it MUST apply those gains
+ <spanx style="emph">in addition</spanx> to the 'output gain' value.
+If a tool modifies the ID header's 'output gain' field, it MUST also update or

+To avoid confusion with multiple normalization schemes, an Opus comment header
+ SHOULD NOT contain any of the REPLAYGAIN_TRACK_GAIN, REPLAYGAIN_TRACK_PEAK,
+ REPLAYGAIN_ALBUM_GAIN, or REPLAYGAIN_ALBUM_PEAK tags, unless they are only
+ to be used in some context where there is guaranteed to be no such confusion.
+<xref target="EBU-R128"/> normalization is preferred to the earlier

+<section anchor="packet_size_limits" title="Packet Size Limits">
+<t>
+Technically, valid Opus packets can be arbitrarily large due to the padding
+ format, although the amount of non-padding data they can contain is bounded.
+These packets might be spread over a similarly enormous number of Ogg pages.
+When encoding, implementations SHOULD limit the use of padding in audio data
+ packets to no more than is necessary to make a variable bitrate (VBR) stream
+ constant bitrate (CBR), unless they have no reasonable way to determine what
+ is necessary.
+Demuxers SHOULD treat audio data packets as invalid (treat them as if they were
+ malformed Opus packets with an invalid TOC sequence) if they are larger than
+ 61,440 octets per Opus stream, unless they have a specific reason for
+ allowing extra padding.
+Such packets necessarily contain more padding than needed to make a stream CBR.
+Demuxers MUST avoid attempting to allocate excessive amounts of memory when
+ presented with a very large packet.
+Demuxers MAY treat audio data packets as invalid or partially process them if
+ they are larger than 61,440 octets in an Ogg Opus stream with channel
+ mapping families 0 or 1.
+Demuxers MAY treat audio data packets as invalid or partially process them in
+ any Ogg Opus stream if the packet is larger than 61,440 octets and also
+ larger than 7,680 octets per Opus stream.
+The presence of an extremely large packet in the stream could indicate a
+ memory exhaustion attack or stream corruption.
+</t>
+<t>
+In an Ogg Opus stream, the largest possible valid packet that does not use
+ padding has a size of (61,298*N - 2) octets.
+With 255 streams, this is 15,630,988 octets and can
+ span up to 61,298 Ogg pages, all but one of which will have a granule
+ position of -1.
+This is of course a very extreme packet, consisting of 255 streams, each
+ containing 120 ms of audio encoded as 2.5 ms frames, each frame
+ using the maximum possible number of octets (1275) and stored in the least
+ efficient manner allowed (a VBR code 3 Opus packet).
+Even in such a packet, most of the data will be zeros as 2.5 ms frames
+ cannot actually use all 1275 octets.
+</t>
+<t>
+The largest packet consisting of entirely useful data is
+ (15,326*N - 2) octets.
+This corresponds to 120 ms of audio encoded as 10 ms frames in either
+ SILK or Hybrid mode, but at a data rate of over 1 Mbps, which makes little
+ sense for the quality achieved.
+</t>
+<t>
+A more reasonable limit is (7,664*N - 2) octets.
+This corresponds to 120 ms of audio encoded as 20 ms stereo CELT mode
+ frames, with a total bitrate just under 511 kbps (not counting the Ogg
+ encapsulation overhead).
+For channel mapping family 1, N=8 provides a reasonable upper bound, as it
+ allows for each of the 8 possible output channels to be decoded from a
+ separate stereo Opus stream.
+This gives a size of 61,310 octets, which is rounded up to a multiple of
+ 1,024 octets to yield the audio data packet size of 61,440 octets
+ that any implementation is expected to be able to process successfully.

+<section anchor="encoder" title="Encoder Guidelines">
+<t>
+When encoding Opus streams, Ogg muxers SHOULD take into account the
+ algorithmic delay of the Opus encoder.
+</t>
+<t>
+In encoders derived from the reference
+ implementation <xref target="RFC6716"/>, the number of samples can be
+ queried with:
+</t>
+<figure align="center">
+<artwork align="center"><![CDATA[
+ opus_encoder_ctl(encoder_state, OPUS_GET_LOOKAHEAD(&delay_samples));
+]]></artwork>
+</figure>
+<t>
+To achieve good quality in the very first samples of a stream, implementations
+ MAY use linear predictive coding (LPC) extrapolation to generate at least 120
+ extra samples at the beginning to avoid the Opus encoder having to encode a
+ discontinuous signal.
+For more information on linear prediction, see
+ <xref target="linear-prediction"/>.
+For an input file containing 'length' samples, the implementation SHOULD set
+ the pre-skip header value to (delay_samples + extra_samples), encode
+ at least (length + delay_samples + extra_samples)
+ samples, and set the granule position of the last page to
+ (length + delay_samples + extra_samples).
+This ensures that the encoded file has the same duration as the original, with
+ no time offset. The best way to pad the end of the stream is to also use LPC
+ extrapolation, but zero-padding is also acceptable.
+</t>
+
+<section anchor="lpc" title="LPC Extrapolation">
+<t>
+The first step in LPC extrapolation is to compute linear prediction
+ coefficients. <xref target="lpc-sample"/>
+When extending the end of the signal, order-N (typically with N ranging from 8
+ to 40) LPC analysis is performed on a window near the end of the signal.
+The last N samples are used as memory to an infinite impulse response (IIR)
+ filter.
+</t>
+<t>
+The filter is then applied on a zero input to extrapolate the end of the signal.
+Let a(k) be the kth LPC coefficient and x(n) be the nth sample of the signal,
+ each new sample past the end of the signal is computed as:

+x(n) = \ a(k)*x(n-k)
+ /

+ k=1
+]]></artwork>
+</figure>
+<t>
+The process is repeated independently for each channel.
+It is possible to extend the beginning of the signal by applying the same
+ process backward in time.
+When extending the beginning of the signal, it is best to apply a "fade in" to
+ the extrapolated signal, e.g. by multiplying it by a half-Hanning window
+ <xref target="hanning"/>.

+
+<section anchor="continuous_chaining" title="Continuous Chaining">
+<t>
+In some applications, such as Internet radio, it is desirable to cut a long
+ stream into smaller chains, e.g. so the comment header can be updated.
+This can be done simply by separating the input streams into segments and
+ encoding each segment independently.
+The drawback of this approach is that it creates a small discontinuity
+ at the boundary due to the lossy nature of Opus.
+A muxer MAY avoid this discontinuity by using the following procedure:
+<list style="numbers">
+<t>Encode the last frame of the first segment as an independent frame by
+ turning off all forms of inter-frame prediction.
+De-emphasis is allowed.</t>
+<t>Set the granule position of the last page to a point near the end of the
+ last frame.</t>
+<t>Begin the second segment with a copy of the last frame of the first
+ segment.</t>
+<t>Set the pre-skip value of the second stream in such a way as to properly
+ join the two streams.</t>
+<t>Continue the encoding process normally from there, without any reset to
+ the encoder.</t>
+</list>
+</t>
+<t>
+In encoders derived from the reference implementation, inter-frame prediction

+
+<section anchor="security" title="Security Considerations">
+<t>
+Implementations of the Opus codec need to take appropriate security
+ considerations into account, as outlined in <xref target="RFC4732"/>.
+This is just as much a problem for the container as it is for the codec itself.
+Malicious payloads and/or input streams can be used to attack codec
+ implementations.
+Implementations MUST NOT overrun their allocated memory nor consume excessive
+ resources when decoding payloads or processing input streams.
+Although problems in encoding applications are typically rarer, this still
+ applies to a muxer, as vulnerabilities would allow an attacker to attack
+ transcoding gateways.
+</t>
+
+<t>
+Header parsing code contains the most likely area for potential overruns.
+It is important for implementations to ensure their buffers contain enough
+ data for all of the required fields before attempting to read it (for example,
+ for all of the channel map data in the ID header).
+Implementations would do well to validate the indices of the channel map, also,
+ to ensure they meet all of the restrictions outlined in
+ <xref target="channel_mapping"/>, in order to avoid attempting to read data
+ from channels that do not exist.
+</t>
+
+<t>
+To avoid excessive resource usage, we advise implementations to be especially
+ wary of streams that might cause them to process far more data than was
+ actually transmitted.
+For example, a relatively small comment header may contain values for the
+ string lengths or user comment list length that imply that it is many
+ gigabytes in size.
+Even computing the size of the required buffer could overflow a 32-bit integer,
+ and actually attempting to allocate such a buffer before verifying it would be
+ a reasonable size is a bad idea.
+After reading the user comment list length, implementations might wish to
+ verify that the header contains at least the minimum amount of data for that
+ many comments (4 additional octets per comment, to indicate each has a
+ length of zero) before proceeding any further, again taking care to avoid
+ overflow in these calculations.
+If allocating an array of pointers to point at these strings, the size of the
+ pointers may be larger than 4 octets, potentially requiring a separate
+ overflow check.
+</t>
+
+<t>
+Another bug in this class we have observed more than once involves the handling
+ of invalid data at the end of a stream.
+Often, implementations will seek to the end of a stream to locate the last
+ timestamp in order to compute its total duration.
+If they do not find a valid capture pattern and Ogg page from the desired
+ logical stream, they will back up and try again.
+If care is not taken to avoid re-scanning data that was already scanned, this
+ search can quickly devolve into something with a complexity that is quadratic
+ in the amount of invalid data.
+</t>
+
+<t>
+In general when seeking, implementations will wish to be cautious about the
+ effects of invalid granule position values, and ensure all algorithms will
+ continue to make progress and eventually terminate, even if these are missing
+ or out-of-order.
+</t>
+
+<t>
+Like most other container formats, Ogg Opus streams SHOULD NOT be used with
+ insecure ciphers or cipher modes that are vulnerable to known-plaintext
+ attacks.
+Elements such as the Ogg page capture pattern and the magic signatures in the
+ ID header and the comment header all have easily predictable values, in
+ addition to various elements of the codec data itself.

+ <section title="Introduction">
+ <t>This document addresses minor issues that were discovered in the reference
+ implementation of the Opus codec that serves as the specification in
+ <xref target="RFC6716">RFC 6716</xref>. Only issues affecting the decoder are
+ listed here. An up-to-date implementation of the Opus encoder can be found at
+ http://opus-codec.org/. The updated specification remains fully compatible with
+ the original specification and only one of the changes results in any difference
+ in the audio output.

+ <t>The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",

+ </section>
+
+ <section title="Stereo State Reset in SILK">
+ <t>The reference implementation does not reinitialize the stereo state
+ during a mode switch. The old stereo memory can produce a brief impulse
+ (i.e. single sample) in the decoded audio. This can be fixed by changing
+ silk/dec_API.c at line 72:

++ sizeof(((silk_decoder *)decState)->sStereo));
++ /* Not strictly needed, but it's cleaner that way */
++ ((silk_decoder *)decState)->prev_decode_only_middle = 0;
+
+ return ret;
+ }
+]]></artwork>
+</figure>
+ <t>
+ This change affects the normative part of the decoder, although the
+ amount of change is too small to make a significant impact on testvectors.
+ </t>
+ </section>
+
+ <section anchor="padding" title="Parsing of the Opus Packet Padding">
+ <t>It was discovered that some invalid packets of very large size could trigger
+ an out-of-bounds read in the Opus packet parsing code responsible for padding.
+ This is due to an integer overflow if the signaled padding exceeds 2^31-1 bytes
+ (the actual packet may be smaller). The code can be fixed by applying the following
+ changes at line 596 of src/opus_decoder.c:
+ </t>
+<figure>
+<artwork><![CDATA[
+ /* Padding flag is bit 6 */
+ if (ch&0x40)
+ {
+- int padding=0;
+ int p;
+ do {
+ if (len<=0)
+ return OPUS_INVALID_PACKET;
+ p = *data++;
+ len--;
+- padding += p==255 ? 254: p;
++ len -= p==255 ? 254: p;
+ } while (p==255);
+- len -= padding;
+ }
+]]></artwork>
+</figure>
+ <t>This packet parsing issue is limited to reading memory up
+ to about 60 kB beyond the compressed buffer. This can only be triggered
+ by a compressed packet more than about 16 MB long, so it's not a problem
+ for RTP. In theory, it <spanx style="emph">could</spanx> crash a file
+ decoder (e.g. Opus in Ogg) if the memory just after the incoming packet
+ is out-of-range, but our attempts to trigger such a crash in a production
+ application built using an affected version of the Opus decoder failed.</t>
+ </section>
+
+ <section anchor="resampler" title="Resampler buffer">
+ <t>The SILK resampler had the following issues:
+ <list style="numbers">
+ <t>The calls to memcpy() were using sizeof(opus_int32), but the type of the
+ local buffer was opus_int16.</t>
+ <t>Because the size was wrong, this potentially allowed the source
+ and destination regions of the memcpy() to overlap.
+ We <spanx style="emph">believe</spanx> that nSamplesIn is at least fs_in_khZ,
+ which is at least 8.
+ Since RESAMPLER_ORDER_FIR_12 is only 8, that should not be a problem once
+ the type size is fixed.</t>
+ <t>The size of the buffer used RESAMPLER_MAX_BATCH_SIZE_IN, but the
+ data stored in it was actually _twice_ the input batch size
+ (nSamplesIn<<1).</t>
+ </list></t>
+ <t>
+ The fact that the code never produced any error in testing (including when run under the
+ Valgrind memory debugger), suggests that in practice
+ the batch sizes are reasonable enough that none of the issues above
+ was ever a problem. However, proving that is non-obvious.

+ <section title="Downmix to Mono" anchor="stereo">
+ <t>The last issue is not strictly a bug, but it is an issue that has been reported
+ when downmixing an Opus decoded stream to mono, whether this is done inside the decoder
+ or as a post-processing step on the stereo decoder output. Opus intensity stereo allows
+ optionally coding the two channels 180-degrees out of phase on a per-band basis.
+ This provides better stereo quality than forcing the two channels to be in phase,
+ but when the output is downmixed to mono, the energy in the affected bands is cancelled
+ sometimes resulting in audible artefacts.
+ </t>
+ <t>As a work-around for this issue, the decoder MAY choose not to apply the 180-degree
+ phase shift when the output is meant to be downmixed (inside or
+ outside of the decoder).
+ </t>
+ </section>
+
+ <section title="Hybrid Folding" anchor="folding">
+ <t>When encoding in hybrid mode at low bitrate, we sometimes only have
+ enough bits to code a single CELT band (8 - 9.6 kHz). When that happens,
+ the second band (CELT band 18, from 9.6 to 12 kHz) cannot use folding
+ because it is wider than the amount already coded, and falls back to
+ LCG noise. Because it can also happen on transients (e.g. stops), it
+ can cause audible pre-echo.
+ </t>
+ <t>
+ To address the issue, we change the folding behaviour so that it is
+ never forced to fall back to LCG due to the first band not containing
+ enough coefficients to fold onto the second band. This
+ is achieved by simply repeating part of the first band in the folding
+ of the second band. This changes the code in celt/bands.c around line 1237:

+ The fix does not impact compatibility, because the improvement does

+ <section title="New Test Vectors">
+ <t>Changes in <xref target="stereo"/> and <xref target="folding"/> have
+ sufficient impact on the testvectors to make them fail. For this reason,

+ include two decoded outputs for the same bitstream. The outputs with
+ suffix 'm' do not apply the CELT 180-degree phase shift as allowed in
+ <xref target="stereo"/>, while the outputs with suffix 's' do. An
+ implementation is compliant as long as it passes either the 'm' or the
+ 's' set of vectors.
+ </t>
+ <t>
+ In addition, any Opus implementation
+ that passes the original test vectors from <xref target="RFC6716">RFC 6716</xref>

+This document defines the Opus interactive speech and audio codec.
+Opus is designed to handle a wide range of interactive audio applications,
+ including Voice over IP, videoconferencing, in-game chat, and even live,
+ distributed music performances.
+It scales from low bitrate narrowband speech at 6 kb/s to very high quality
+ stereo music at 510 kb/s.
+Opus uses both linear prediction (LP) and the Modified Discrete Cosine
+ Transform (MDCT) to achieve good compression of both speech and music.
+</t>
+</abstract>
+</front>
+
+<middle>
+
+<section anchor="introduction" title="Introduction">
+<t>
+The Opus codec is a real-time interactive audio codec designed to meet the requirements
+described in <xref target="requirements"></xref>.
+It is composed of a linear
+ prediction (LP)-based <xref target="LPC"/> layer and a Modified Discrete Cosine Transform
+ (MDCT)-based <xref target="MDCT"/> layer.
+The main idea behind using two layers is that in speech, linear prediction
+ techniques (such as Code-Excited Linear Prediction, or CELP) code low frequencies more efficiently than transform
+ (e.g., MDCT) domain techniques, while the situation is reversed for music and
+ higher speech frequencies.
+Thus a codec with both layers available can operate over a wider range than
+ either one alone and, by combining them, achieve better quality than either
+ one individually.
+</t>
+
+<t>
+The primary normative part of this specification is provided by the source code
+ in <xref target="ref-implementation"></xref>.
+Only the decoder portion of this software is normative, though a
+ significant amount of code is shared by both the encoder and decoder.
+<xref target="conformance"/> provides a decoder conformance test.
+The decoder contains a great deal of integer and fixed-point arithmetic which
+ needs to be performed exactly, including all rounding considerations, so any
+ useful specification requires domain-specific symbolic language to adequately
+ define these operations.
+Additionally, any
+conflict between the symbolic representation and the included reference
+implementation must be resolved. For the practical reasons of compatibility and
+testability it would be advantageous to give the reference implementation
+priority in any disagreement. The C language is also one of the most
+widely understood human-readable symbolic representations for machine
+behavior.
+For these reasons this RFC uses the reference implementation as the sole
+ symbolic representation of the codec.
+</t>
+
+<t>While the symbolic representation is unambiguous and complete it is not
+always the easiest way to understand the codec's operation. For this reason
+this document also describes significant parts of the codec in English and
+takes the opportunity to explain the rationale behind many of the more
+surprising elements of the design. These descriptions are intended to be
+accurate and informative, but the limitations of common English sometimes
+result in ambiguity, so it is expected that the reader will always read
+them alongside the symbolic representation. Numerous references to the
+implementation are provided for this purpose. The descriptions sometimes
+differ from the reference in ordering or through mathematical simplification
+wherever such deviation makes an explanation easier to understand.
+For example, the right shift and left shift operations in the reference
+implementation are often described using division and multiplication in the text.
+In general, the text is focused on the "what" and "why" while the symbolic
+representation most clearly provides the "how".

+<section anchor="overview" title="Opus Codec Overview">
+
+<t>
+The Opus codec scales from 6 kb/s narrowband mono speech to 510 kb/s
+ fullband stereo music, with algorithmic delays ranging from 5 ms to
+ 65.2 ms.
+At any given time, either the LP layer, the MDCT layer, or both, may be active.
+It can seamlessly switch between all of its various operating modes, giving it
+ a great deal of flexibility to adapt to varying content and network
+ conditions without renegotiating the current session.
+The codec allows input and output of various audio bandwidths, defined as
+ follows:
+</t>
+<texttable anchor="audio-bandwidth">
+<ttcol>Abbreviation</ttcol>
+<ttcol align="right">Audio Bandwidth</ttcol>
+<ttcol align="right">Sample Rate (Effective)</ttcol>
+<c>NB (narrowband)</c> <c>4 kHz</c> <c>8 kHz</c>
+<c>MB (medium-band)</c> <c>6 kHz</c> <c>12 kHz</c>
+<c>WB (wideband)</c> <c>8 kHz</c> <c>16 kHz</c>
+<c>SWB (super-wideband)</c> <c>12 kHz</c> <c>24 kHz</c>
+<c>FB (fullband)</c> <c>20 kHz (*)</c> <c>48 kHz</c>
+</texttable>
+<t>
+(*) Although the sampling theorem allows a bandwidth as large as half the
+ sampling rate, Opus never codes audio above 20 kHz, as that is the
+ generally accepted upper limit of human hearing.
+</t>
+
+<t>
+Opus defines super-wideband (SWB) with an effective sample rate of 24 kHz,
+ unlike some other audio coding standards that use 32 kHz.
+This was chosen for a number of reasons.
+The band layout in the MDCT layer naturally allows skipping coefficients for
+ frequencies over 12 kHz, but does not allow cleanly dropping just those
+ frequencies over 16 kHz.
+A sample rate of 24 kHz also makes resampling in the MDCT layer easier,
+ as 24 evenly divides 48, and when 24 kHz is sufficient, it can save
+ computation in other processing, such as Acoustic Echo Cancellation (AEC).
+Experimental changes to the band layout to allow a 16 kHz cutoff
+ (32 kHz effective sample rate) showed potential quality degradations at
+ other sample rates, and at typical bitrates the number of bits saved by using
+ such a cutoff instead of coding in fullband (FB) mode is very small.
+Therefore, if an application wishes to process a signal sampled at 32 kHz,
+ it should just use FB.
+</t>
+
+<t>
+The LP layer is based on the SILK codec
+ <xref target="SILK"></xref>.
+It supports NB, MB, or WB audio and frame sizes from 10 ms to 60 ms,
+ and requires an additional 5 ms look-ahead for noise shaping estimation.
+A small additional delay (up to 1.5 ms) may be required for sampling rate
+ conversion.
+Like Vorbis <xref target='Vorbis-website'/> and many other modern codecs, SILK is inherently designed for
+ variable-bitrate (VBR) coding, though the encoder can also produce
+ constant-bitrate (CBR) streams.
+The version of SILK used in Opus is substantially modified from, and not
+ compatible with, the stand-alone SILK codec previously deployed by Skype.
+This document does not serve to define that format, but those interested in the
+ original SILK codec should see <xref target="SILK"/> instead.
+</t>
+
+<t>
+The MDCT layer is based on the CELT codec <xref target="CELT"></xref>.
+It supports NB, WB, SWB, or FB audio and frame sizes from 2.5 ms to
+ 20 ms, and requires an additional 2.5 ms look-ahead due to the
+ overlapping MDCT windows.
+The CELT codec is inherently designed for CBR coding, but unlike many CBR
+ codecs it is not limited to a set of predetermined rates.
+It internally allocates bits to exactly fill any given target budget, and an
+ encoder can produce a VBR stream by varying the target on a per-frame basis.
+The MDCT layer is not used for speech when the audio bandwidth is WB or less,
+ as it is not useful there.
+On the other hand, non-speech signals are not always adequately coded using
+ linear prediction, so for music only the MDCT layer should be used.
+</t>
+
+<t>
+A "Hybrid" mode allows the use of both layers simultaneously with a frame size
+ of 10 or 20 ms and a SWB or FB audio bandwidth.
+The LP layer codes the low frequencies by resampling the signal down to WB.
+The MDCT layer follows, coding the high frequency portion of the signal.
+The cutoff between the two lies at 8 kHz, the maximum WB audio bandwidth.
+In the MDCT layer, all bands below 8 kHz are discarded, so there is no
+ coding redundancy between the two layers.
+</t>
+
+<t>
+The sample rate (in contrast to the actual audio bandwidth) can be chosen
+ independently on the encoder and decoder side, e.g., a fullband signal can be
+ decoded as wideband, or vice versa.
+This approach ensures a sender and receiver can always interoperate, regardless
+ of the capabilities of their actual audio hardware.
+Internally, the LP layer always operates at a sample rate of twice the audio
+ bandwidth, up to a maximum of 16 kHz, which it continues to use for SWB
+ and FB.
+The decoder simply resamples its output to support different sample rates.
+The MDCT layer always operates internally at a sample rate of 48 kHz.
+Since all the supported sample rates evenly divide this rate, and since the
+ the decoder may easily zero out the high frequency portion of the spectrum in
+ the frequency domain, it can simply decimate the MDCT layer output to achieve
+ the other supported sample rates very cheaply.
+</t>
+
+<t>
+After conversion to the common, desired output sample rate, the decoder simply
+ adds the output from the two layers together.
+To compensate for the different look-ahead required by each layer, the CELT
+ encoder input is delayed by an additional 2.7 ms.
+This ensures that low frequencies and high frequencies arrive at the same time.
+This extra delay may be reduced by an encoder by using less look-ahead for noise
+ shaping or using a simpler resampler in the LP layer, but this will reduce
+ quality.
+However, the base 2.5 ms look-ahead in the CELT layer cannot be reduced in
+ the encoder because it is needed for the MDCT overlap, whose size is fixed by
+ the decoder.
+</t>
+
+<t>
+Both layers use the same entropy coder, avoiding any waste from "padding bits"
+ between them.
+The hybrid approach makes it easy to support both CBR and VBR coding.
+Although the LP layer is VBR, the bit allocation of the MDCT layer can produce
+ a final stream that is CBR by using all the bits left unused by the LP layer.
+</t>
+
+<section title="Control Parameters">
+<t>
+The Opus codec includes a number of control parameters which can be changed dynamically during
+regular operation of the codec, without interrupting the audio stream from the encoder to the decoder.
+These parameters only affect the encoder since any impact they have on the bit-stream is signaled
+in-band such that a decoder can decode any Opus stream without any out-of-band signaling. Any Opus
+implementation can add or modify these control parameters without affecting interoperability. The most
+important encoder control parameters in the reference encoder are listed below.
+</t>
+
+<section title="Bitrate" toc="exlcude">
+<t>
+Opus supports all bitrates from 6 kb/s to 510 kb/s. All other parameters being
+equal, higher bitrate results in higher quality. For a frame size of 20 ms, these
+are the bitrate "sweet spots" for Opus in various configurations:
+<list style="symbols">
+<t>8-12 kb/s for NB speech,</t>
+<t>16-20 kb/s for WB speech,</t>
+<t>28-40 kb/s for FB speech,</t>
+<t>48-64 kb/s for FB mono music, and</t>
+<t>64-128 kb/s for FB stereo music.</t>
+</list>
+</t>
+</section>
+
+<section title="Number of Channels (Mono/Stereo)" toc="exlcude">
+<t>
+Opus can transmit either mono or stereo frames within a single stream.
+When decoding a mono frame in a stereo decoder, the left and right channels are
+ identical, and when decoding a stereo frame in a mono decoder, the mono output
+ is the average of the left and right channels.
+In some cases, it is desirable to encode a stereo input stream in mono (e.g.,
+ because the bitrate is too low to encode stereo with sufficient quality).
+The number of channels encoded can be selected in real-time, but by default the
+ reference encoder attempts to make the best decision possible given the
+ current bitrate.
+</t>
+</section>
+
+<section title="Audio Bandwidth" toc="exlcude">
+<t>
+The audio bandwidths supported by Opus are listed in
+ <xref target="audio-bandwidth"/>.
+Just like for the number of channels, any decoder can decode audio encoded at
+ any bandwidth.
+For example, any Opus decoder operating at 8 kHz can decode a FB Opus
+ frame, and any Opus decoder operating at 48 kHz can decode a NB frame.
+Similarly, the reference encoder can take a 48 kHz input signal and
+ encode it as NB.
+The higher the audio bandwidth, the higher the required bitrate to achieve
+ acceptable quality.
+The audio bandwidth can be explicitly specified in real-time, but by default
+ the reference encoder attempts to make the best bandwidth decision possible
+ given the current bitrate.
+</t>
+</section>
+
+
+<section title="Frame Duration" toc="exlcude">
+<t>
+Opus can encode frames of 2.5, 5, 10, 20, 40 or 60 ms.
+It can also combine multiple frames into packets of up to 120 ms.
+For real-time applications, sending fewer packets per second reduces the
+ bitrate, since it reduces the overhead from IP, UDP, and RTP headers.
+However, it increases latency and sensitivity to packet losses, as losing one
+ packet constitutes a loss of a bigger chunk of audio.
+Increasing the frame duration also slightly improves coding efficiency, but the
+ gain becomes small for frame sizes above 20 ms.
+For this reason, 20 ms frames are a good choice for most applications.
+</t>
+</section>
+
+<section title="Complexity" toc="exlcude">
+<t>
+There are various aspects of the Opus encoding process where trade-offs
+can be made between CPU complexity and quality/bitrate. In the reference
+encoder, the complexity is selected using an integer from 0 to 10, where
+0 is the lowest complexity and 10 is the highest. Examples of
+computations for which such trade-offs may occur are:
+<list style="symbols">
+<t>The order of the pitch analysis whitening filter <xref target="Whitening"/>,</t>
+<t>The order of the short-term noise shaping filter,</t>
+<t>The number of states in delayed decision quantization of the
+residual signal, and</t>
+<t>The use of certain bit-stream features such as variable time-frequency
+resolution and the pitch post-filter.</t>
+</list>
+</t>
+</section>
+
+<section title="Packet Loss Resilience" toc="exlcude">
+<t>
+Audio codecs often exploit inter-frame correlations to reduce the
+bitrate at a cost in error propagation: after losing one packet
+several packets need to be received before the decoder is able to
+accurately reconstruct the speech signal. The extent to which Opus
+exploits inter-frame dependencies can be adjusted on the fly to
+choose a trade-off between bitrate and amount of error propagation.
+</t>
+</section>
+
+<section title="Forward Error Correction (FEC)" toc="exlcude">
+<t>
+ Another mechanism providing robustness against packet loss is the in-band
+ Forward Error Correction (FEC). Packets that are determined to
+ contain perceptually important speech information, such as onsets or
+ transients, are encoded again at a lower bitrate and this re-encoded
+ information is added to a subsequent packet.
+</t>
+</section>
+
+<section title="Constant/Variable Bitrate" toc="exlcude">
+<t>
+Opus is more efficient when operating with variable bitrate (VBR), which is
+the default. However, in some (rare) applications, constant bitrate (CBR)
+is required. There are two main reasons to operate in CBR mode:
+<list style="symbols">
+<t>When the transport only supports a fixed size for each compressed frame</t>
+<t>When encryption is used for an audio stream that is either highly constrained
+ (e.g. yes/no, recorded prompts) or highly sensitive <xref target="SRTP-VBR"></xref> </t>
+</list>
+
+When low-latency transmission is required over a relatively slow connection, then
+constrained VBR can also be used. This uses VBR in a way that simulates a
+"bit reservoir" and is equivalent to what MP3 (MPEG 1, Layer 3) and
+AAC (Advanced Audio Coding) call CBR (i.e., not true
+CBR due to the bit reservoir).
+</t>
+</section>
+
+<section title="Discontinuous Transmission (DTX)" toc="exlcude">
+<t>
+ Discontinuous Transmission (DTX) reduces the bitrate during silence
+ or background noise. When DTX is enabled, only one frame is encoded
+ every 400 milliseconds.
+</t>
+</section>
+

+
+</section>
+
+<section anchor="modes" title="Internal Framing">
+
+<t>
+The Opus encoder produces "packets", which are each a contiguous set of bytes
+ meant to be transmitted as a single unit.
+The packets described here do not include such things as IP, UDP, or RTP
+ headers which are normally found in a transport-layer packet.
+A single packet may contain multiple audio frames, so long as they share a
+ common set of parameters, including the operating mode, audio bandwidth, frame
+ size, and channel count (mono vs. stereo).
+This section describes the possible combinations of these parameters and the
+ internal framing used to pack multiple frames into a single packet.
+This framing is not self-delimiting.
+Instead, it assumes that a higher layer (such as UDP or RTP <xref target='RFC3550'/>
+or Ogg <xref target='RFC3533'/> or Matroska <xref target='Matroska-website'/>)
+ will communicate the length, in bytes, of the packet, and it uses this
+ information to reduce the framing overhead in the packet itself.
+A decoder implementation MUST support the framing described in this section.
+An alternative, self-delimiting variant of the framing is described in
+ <xref target="self-delimiting-framing"/>.
+Support for that variant is OPTIONAL.

+<section title="Code 3: A Signaled Number of Frames in the Packet">
+<t anchor="R5">
+Code 3 packets signal the number of frames, as well as additional
+ padding, called "Opus padding" to indicate that this padding is added at the
+ Opus layer, rather than at the transport layer.
+Code 3 packets MUST have at least 2 bytes [R6,R7].
+The TOC byte is followed by a byte encoding the number of frames in the packet
+ in bits 2 to 7 (marked "M" in <xref target='frame_count_byte'/>), with bit 1 indicating whether
+ or not Opus padding is inserted (marked "p" in <xref target='frame_count_byte'/>), and bit 0
+ indicating VBR (marked "v" in <xref target='frame_count_byte'/>).
+M MUST NOT be zero, and the audio duration contained within a packet MUST NOT
+ exceed 120 ms [R5].
+This limits the maximum frame count for any frame size to 48 (for 2.5 ms
+ frames), with lower limits for longer frame sizes.

+ byte.

+<t>
+When Opus padding is used, the number of bytes of padding is encoded in the
+ bytes following the frame count byte.
+Values from 0...254 indicate that 0...254 bytes of padding are included,
+ in addition to the byte(s) used to indicate the size of the padding.
+If the value is 255, then the size of the additional padding is 254 bytes,
+ plus the padding value encoded in the next byte.
+There MUST be at least one more byte in the packet in this case [R6,R7].
+The additional padding bytes appear at the end of the packet, and MUST be set
+ to zero by the encoder to avoid creating a covert channel.
+The decoder MUST accept any value for the padding bytes, however.
+</t>
+<t>
+Although this encoding provides multiple ways to indicate a given number of
+ padding bytes, each uses a different number of bytes to indicate the padding
+ size, and thus will increase the total packet size by a different amount.
+For example, to add 255 bytes to a packet, set the padding bit, p, to 1, insert
+ a single byte after the frame count byte with a value of 254, and append 254
+ padding bytes with the value zero to the end of the packet.
+To add 256 bytes to a packet, set the padding bit to 1, insert two bytes after
+ the frame count byte with the values 255 and 0, respectively, and append 254
+ padding bytes with the value zero to the end of the packet.
+By using the value 255 multiple times, it is possible to create a packet of any
+ specific, desired size.
+Let P be the number of header bytes used to indicate the padding size plus the
+ number of padding bytes themselves (i.e., P is the total number of bytes added
+ to the packet).
+Then P MUST be no more than N-2 [R6,R7].
+</t>
+<t anchor="R6">
+In the CBR case, let R=N-2-P be the number of bytes remaining in the packet
+ after subtracting the (optional) padding.
+Then the compressed length of each frame in bytes is equal to R/M.
+The value R MUST be a non-negative integer multiple of M [R6].
+The compressed data for all M frames follows, each of size
+ R/M bytes, as illustrated in <xref target="code3cbr_packet"/>.

+The context is described by a single parameter, logp, which is the absolute
+ value of the base-2 logarithm of the probability of a "1".
+It is mathematically equivalent to calling ec_decode() with

+</t>
+</section>
+<section anchor="ec_dec_icdf" title="ec_dec_icdf()">
+<t>
+The last is ec_dec_icdf() (entdec.c), which decodes a single symbol with a
+ table-based context of up to 8 bits, also replacing both the ec_decode() and
+ ec_dec_update() steps, as well as the search for the decoded symbol in between.
+The context is described by two parameters, an icdf
+ ("inverse" cumulative distribution function) table and ftb.
+As with ec_decode_bin(), (1<<ftb) is equivalent to ft.
+idcf[k], on the other hand, stores (1<<ftb)-fh[k], which is equal to
+ (1<<ftb) - fl[k+1].
+fl[0] is assumed to be 0, and the table is terminated by a value of 0 (where
+ fh[k] == ft).
+</t>
+<t>
+The function is mathematically equivalent to calling ec_decode() with
+ ft = (1<<ftb), using the returned value fs to search the table
+ for the first entry where fs < (1<<ftb)-icdf[k], and
+ calling ec_dec_update() with
+ fl[k] = (1<<ftb) - icdf[k-1] (or 0
+ if k == 0), fh[k] = (1<<ftb) - idcf[k],
+ and ft = (1<<ftb).
+Combining the search with the update allows the division to be replaced by a
+ series of multiplications (which are usually much cheaper), and using an

+Although icdf[k] is more convenient for the code, the frequency counts, f[k],
+ are a more natural representation of the probability distribution function
+ (PDF) for a given symbol.
+Therefore this draft lists the latter, not the former, when describing the
+ context in which a symbol is coded as a list, e.g., {4, 4, 4, 4}/16 for a
+ uniform context with four possible values and ft = 16.
+The value of ft after the slash is always the sum of the entries in the PDF,
+ but is included for convenience.
+Contexts with identical probabilities, f[k]/ft, but different values of ft
+ (or equivalently, ftb) are not the same, and cannot, in general, be used in
+ place of one another.
+An icdf table is also not capable of representing a PDF where the first symbol
+ has 0 probability.
+In such contexts, ec_dec_icdf() can decode the symbol by using a table that
+ drops the entries for any initial zero-probability values and adding the
+ constant offset of the first value with a non-zero probability to its return
+ value.

+<section anchor="decoding-bits" title="Decoding Raw Bits">
+<t>
+The raw bits used by the CELT layer are packed at the end of the packet, with
+ the least significant bit of the first value packed in the least significant
+ bit of the last byte, filling up to the most significant bit in the last byte,
+ continuing on to the least significant bit of the penultimate byte, and so on.
+The reference implementation reads them using ec_dec_bits() (entdec.c).
+Because the range decoder must read several bytes ahead in the stream, as
+ described in <xref target="range-decoder-renorm"/>, the input consumed by the
+ raw bits may overlap with the input consumed by the range coder, and a decoder
+ MUST allow this.
+The format should render it impossible to attempt to read more raw bits than
+ there are actual bits in the frame, though a decoder may wish to check for
+ this and report an error.
+</t>

+
+<section anchor="ec_dec_uint" title="Decoding Uniformly Distributed Integers">
+<t>
+The function ec_dec_uint() (entdec.c) decodes one of ft equiprobable values in
+ the range 0 to (ft - 1), inclusive, each with a frequency of 1,
+ where ft may be as large as (2**32 - 1).
+Because ec_decode() is limited to a total frequency of (2**16 - 1),
+ it splits up the value into a range coded symbol representing up to 8 of the
+ high bits, and, if necessary, raw bits representing the remainder of the
+ value.
+The limit of 8 bits in the range coded symbol is a trade-off between
+ implementation complexity, modeling error (since the symbols no longer truly
+ have equal coding cost), and rounding error introduced by the range coder
+ itself (which gets larger as more bits are included).
+Using raw bits reduces the maximum number of divisions required in the worst
+ case, but means that it may be possible to decode a value outside the range
+ 0 to (ft - 1), inclusive.
+</t>
+
+<t>
+ec_dec_uint() takes a single, positive parameter, ft, which is not necessarily
+ a power of two, and returns an integer, t, whose value lies between 0 and
+ (ft - 1), inclusive.
+Let ftb = ilog(ft - 1), i.e., the number of bits required
+ to store (ft - 1) in two's complement notation.
+If ftb is 8 or less, then t is decoded with t = ec_decode(ft), and
+ the range coder state is updated using the three-tuple (t, t + 1,
+ ft).

+If ftb is greater than 8, then the top 8 bits of t are decoded using

+If, at this point, t >= ft, then the current frame is corrupt.
+In that case, the decoder should assume there has been an error in the coding,

+<section anchor="decoder-tell" title="Current Bit Usage">
+<t>
+The bit allocation routines in the CELT decoder need a conservative upper bound
+ on the number of bits that have been used from the current frame thus far,
+ including both range coder bits and raw bits.
+This drives allocation decisions that must match those made in the encoder.
+The upper bound is computed in the reference implementation to whole-bit
+ precision by the function ec_tell() (entcode.h) and to fractional 1/8th bit
+ precision by the function ec_tell_frac() (entcode.c).
+Like all operations in the range coder, it must be implemented in a bit-exact
+ manner, and must produce exactly the same value returned by the same functions
+ in the encoder after encoding the same symbols.
+</t>
+<t>
+ec_tell() is guaranteed to return ceil(ec_tell_frac()/8.0).
+In various places the codec will check to ensure there is enough room to
+ contain a symbol before attempting to decode it.
+In practice, although the number of bits used so far is an upper bound,
+ decoding a symbol whose probability model suggests it has a worst-case cost of
+ p 1/8th bits may actually advance the return value of ec_tell_frac() by
+ p-1, p, or p+1 1/8th bits, due to approximation error in that upper bound,
+ truncation error in the range coder, and for large values of ft, modeling
+ error in ec_dec_uint().
+</t>
+<t>
+However, this error is bounded, and periodic calls to ec_tell() or
+ ec_tell_frac() at precisely defined points in the decoding process prevent it
+ from accumulating.
+For a range coder symbol that requires a whole number of bits (i.e.,
+ for which ft/(fh[k] - fl[k]) is a power of two), where there are at
+ least p 1/8th bits available, decoding the symbol will never cause ec_tell() or
+ ec_tell_frac() to exceed the size of the frame ("bust the budget").
+In this case the return value of ec_tell_frac() will only advance by more than
+ p 1/8th bits if there was an additional, fractional number of bits remaining,
+ and it will never advance beyond the next whole-bit boundary, which is safe,
+ since frames always contain a whole number of bits.
+However, when p is not a whole number of bits, an extra 1/8th bit is required
+ to ensure that decoding the symbol will not bust the budget.
+</t>
+<t>
+The reference implementation keeps track of the total number of whole bits that
+ have been processed by the decoder so far in the variable nbits_total,
+ including the (possibly fractional) number of bits that are currently
+ buffered, but not consumed, inside the range coder.
+nbits_total is initialized to 9 just before the initial range renormalization
+ process completes (or equivalently, it can be initialized to 33 after the
+ first renormalization).
+The extra two bits over the actual amount buffered by the range coder
+ guarantees that it is an upper bound and that there is enough room for the
+ encoder to terminate the stream.
+Each iteration through the range coder's renormalization loop increases
+ nbits_total by 8.
+Reading raw bits increases nbits_total by the number of raw bits read.

+Internally, the LP layer of a single Opus frame is composed of either a single
+ 10 ms regular SILK frame or between one and three 20 ms regular SILK
+ frames.
+A stereo Opus frame may double the number of regular SILK frames (up to a total
+ of six), since it includes separate frames for a mid channel and, optionally,
+ a side channel.
+Optional Low Bit-Rate Redundancy (LBRR) frames, which are reduced-bitrate
+ encodings of previous SILK frames, may be included to aid in recovery from
+ packet loss.
+If present, these appear before the regular SILK frames.
+They are in most respects identical to regular, active SILK frames, except that
+ they are usually encoded with a lower bitrate.
+This draft uses "SILK frame" to refer to either one and "regular SILK frame" if
+ it needs to draw a distinction between the two.
+</t>
+<t>
+Logically, each SILK frame is in turn composed of either two or four 5 ms
+ subframes.
+Various parameters, such as the quantization gain of the excitation and the
+ pitch lag and filter coefficients can vary on a subframe-by-subframe basis.
+Physically, the parameters for each subframe are interleaved in the bitstream,
+ as described in the relevant sections for each parameter.
+</t>
+<t>
+All of these frames and subframes are decoded from the same range coder, with
+ no padding between them.
+Thus packing multiple SILK frames in a single Opus frame saves, on average,
+ half a byte per SILK frame.
+It also allows some parameters to be predicted from prior SILK frames in the
+ same Opus frame, since this does not degrade packet loss robustness (beyond
+ any penalty for merely using fewer, larger packets to store multiple frames).
+</t>
+
+<t>
+Stereo support in SILK uses a variant of mid-side coding, allowing a mono
+ decoder to simply decode the mid channel.
+However, the data for the two channels is interleaved, so a mono decoder must
+ still unpack the data for the side channel.
+It would be required to do so anyway for Hybrid Opus frames, or to support

+<t>
+A SILK frame corresponding to the mid channel of a stereo Opus frame begins
+ with a pair of side channel prediction weights, designed such that zeros
+ indicate normal mid-side coupling.
+Since these weights can change on every frame, the first portion of each frame
+ linearly interpolates between the previous weights and the current ones, using
+ zeros for the previous weights if none are available.
+These prediction weights are never included in a mono Opus frame, and the
+ previous weights are reset to zeros on any transition from mono to stereo.
+They are also not included in an LBRR frame for the side channel, even if the
+ LBRR flags indicate the corresponding mid channel was not coded.
+In that case, the previous weights are used, again substituting in zeros if no
+ previous weights are available since the last decoder reset
+ (see <xref target="decoder-reset"/>).
+</t>
+
+<t>
+To summarize, these weights are coded if and only if
+<list style="symbols">
+<t>This is a stereo Opus frame (<xref target="toc_byte"/>), and</t>
+<t>The current SILK frame corresponds to the mid channel.</t>
+</list>
+</t>
+
+<t>
+The prediction weights are coded in three separate pieces, which are decoded
+ by silk_stereo_decode_pred() (decode_stereo_pred.c).
+The first piece jointly codes the high-order part of a table index for both
+ weights.
+The second piece codes the low-order part of each table index.
+The third piece codes an offset used to linearly interpolate between table
+ indices.
+The details are as follows.

+Let n be an index decoded with the 25-element stage-1 PDF in
+ <xref target="silk_stereo_pred_pdfs"/>.
+Then let i0 and i1 be indices decoded with the stage-2 and stage-3 PDFs in
+ <xref target="silk_stereo_pred_pdfs"/>, respectively, and let i2 and i3
+ be two more indices decoded with the stage-2 and stage-3 PDFs, all in that

+Decoding the second stage residual proceeds as follows.
+For each coefficient, the decoder reads a symbol using the PDF corresponding to
+ I1 from either <xref target="silk_nlsf_nbmb_stage2_cb_sel"/> or
+ <xref target="silk_nlsf_wb_stage2_cb_sel"/>, and subtracts 4 from the result
+ to give an index in the range -4 to 4, inclusive.
+If the index is either -4 or 4, it reads a second symbol using the PDF in
+ <xref target="silk_nlsf_ext_pdf"/>, and adds the value of this second symbol
+ to the index, using the same sign.
+This gives the index, I2[k], a total range of -10 to 10, inclusive.

+The prediction is undone using the procedure implemented in
+ silk_NLSF_residual_dequant() (NLSF_decode.c), which is as follows.
+Each coefficient selects its prediction weight from one of the two lists based
+ on the stage-1 index, I1.
+<xref target="silk_nlsf_nbmb_weight_sel"/> gives the selections for each
+ coefficient for NB and MB, and <xref target="silk_nlsf_wb_weight_sel"/> gives
+ the selections for WB.
+Let d_LPC be the order of the codebook, i.e., 10 for NB and MB, and 16 for WB,
+ and let pred_Q8[k] be the weight for the k'th coefficient selected by this
+ process for 0 <= k < d_LPC-1.
+Then, the stage-2 residual for each coefficient is computed via
+<figure align="center">
+<artwork align="center"><![CDATA[
+res_Q10[k] = (k+1 < d_LPC ? (res_Q10[k+1]*pred_Q8[k])>>8 : 0)
+ + ((((I2[k]<<10) - sign(I2[k])*102)*qstep)>>16) ,
+]]></artwork>
+</figure>
+ where qstep is the Q16 quantization step size, which is 11796 for NB and MB
+ and 9830 for WB (representing step sizes of approximately 0.18 and 0.15,
+ respectively).

+ title="Reconstructing the Normalized LSF Coefficients">
+<t>
+Once the stage-1 index I1 and the stage-2 residual res_Q10[] have been decoded,
+ the final normalized LSF coefficients can be reconstructed.
+</t>
+<t>
+The spectral distortion introduced by the quantization of each LSF coefficient
+ varies, so the stage-2 residual is weighted accordingly, using the
+ low-complexity Inverse Harmonic Mean Weighting (IHMW) function proposed in
+ <xref target="laroia-icassp"/>.
+The weights are derived directly from the stage-1 codebook vector.
+Let cb1_Q8[k] be the k'th entry of the stage-1 codebook vector from
+ <xref target="silk_nlsf_nbmb_codebook"/> or
+ <xref target="silk_nlsf_wb_codebook"/>.
+Then for 0 <= k < d_LPC the following expression
+ computes the square of the weight as a Q18 value:
+<figure align="center">
+<artwork align="center">
+<![CDATA[
+w2_Q18[k] = (1024/(cb1_Q8[k] - cb1_Q8[k-1])
+ + 1024/(cb1_Q8[k+1] - cb1_Q8[k])) << 16 ,
+]]>
+</artwork>
+</figure>
+ where cb1_Q8[-1] = 0 and cb1_Q8[d_LPC] = 256, and the
+ division is integer division.
+This is reduced to an unsquared, Q9 value using the following square-root
+ approximation:
+<figure align="center">
+<artwork align="center"><![CDATA[
+i = ilog(w2_Q18[k])
+f = (w2_Q18[k]>>(i-8)) & 127
+y = ((i&1) ? 32768 : 46214) >> ((32-i)>>1)
+w_Q9[k] = y + ((213*f*y)>>16)
+]]></artwork>
+</figure>
+The constant 46214 here is approximately the square root of 2 in Q15.
+The cb1_Q8[] vector completely determines these weights, and they may be
+ tabulated and stored as 13-bit unsigned values (with a range of 1819 to 5227,
+ inclusive) to avoid computing them when decoding.
+The reference implementation already requires code to compute these weights on
+ unquantized coefficients in the encoder, in silk_NLSF_VQ_weights_laroia()
+ (NLSF_VQ_weights_laroia.c) and its callers, so it reuses that code in the
+ decoder instead of using a pre-computed table to reduce the amount of ROM
+ required.

+For each round, the process first finds the index k such that abs(a32_Q17[k])

+Because this performs the actual saturation in the Q12 domain, but converts the

+The prediction gain of an LPC synthesis filter is the square-root of the output

+Even if the Q12 coefficients would fit, the resulting filter may still have a

+The decoder reads a single delta value using the 21-entry PDF in
+ <xref target="silk_rel_pitch_pdf"/>.
+If the resulting value is zero, it falls back to the absolute coding procedure
+ from the prior paragraph.
+Otherwise, the final primary pitch lag is then
+<figure align="center">
+<artwork align="center"><![CDATA[
+lag = previous_lag + (delta_lag_index - 9)
+]]></artwork>
+</figure>
+ where previous_lag is the primary pitch lag from the most recent frame in the
+ same channel and delta_lag_index is the value just decoded.
+This allows a per-frame change in the pitch lag of -8 to +11 samples.
+The decoder does no clamping at this point, so this value can fall outside the
+ range of 2 ms to 18 ms, and the decoder must use this unclamped
+ value when using relative coding in the next SILK frame (if any).
+However, because an Opus frame can use relative coding for at most two
+ consecutive SILK frames, integer overflow should not be an issue.

+SILK uses a separate 5-tap pitch filter for each subframe, selected from one
+ of three codebooks.
+The three codebooks each represent different rate-distortion trade-offs, with
+ average rates of 1.61 bits/subframe, 3.68 bits/subframe, and
+ 4.85 bits/subframe, respectively.

+
+<t>
+The importance of the filter coefficients generally depends on two factors: the
+ periodicity of the signal and relative energy between the current subframe and
+ the signal from one period earlier.
+Greater periodicity and decaying energy both lead to more important filter
+ coefficients, and thus should be coded with lower distortion and higher rate.
+These properties are relatively stable over the duration of a single SILK
+ frame, hence all of the subframes in a SILK frame choose their filter from the
+ same codebook.
+This is signaled with an explicitly-coded "periodicity index".
+This immediately follows the subframe pitch lags, and is coded using the
+ 3-entry PDF from <xref target="silk_perindex_pdf"/>.

+SILK codes the excitation using a modified version of the Pyramid Vector
+ Quantization (PVQ) codebook <xref target="PVQ"/>.
+The PVQ codebook is designed for Laplace-distributed values and consists of all
+ sums of K signed, unit pulses in a vector of dimension N, where two pulses at
+ the same position are required to have the same sign.
+Thus the codebook includes all integer codevectors y of dimension N that
+ satisfy
+<figure align="center">
+<artwork align="center"><![CDATA[
+N-1
+__
+\ abs(y[j]) = K .
+/_
+j=0
+]]></artwork>
+</figure>
+Unlike regular PVQ, SILK uses a variable-length, rather than fixed-length,
+ encoding.
+This encoding is better suited to the more Gaussian-like distribution of the
+ coefficient magnitudes and the non-uniform distribution of their signs (caused
+ by the quantization offset described below).
+SILK also handles large codebooks by coding the least significant bits (LSBs)
+ of each coefficient directly.
+This adds a small coding efficiency loss, but greatly reduces the computation
+ time and ROM size required for decoding, as implemented in
+ silk_decode_pulses() (decode_pulses.c).
+</t>
+
+<t>
+SILK fixes the dimension of the codebook to N = 16.
+The excitation is made up of a number of "shell blocks", each 16 samples in
+ size.
+<xref target="silk_shell_block_table"/> lists the number of shell blocks
+ required for a SILK frame for each possible audio bandwidth and frame size.
+10 ms MB frames nominally contain 120 samples (10 ms at
+ 12 kHz), which is not a multiple of 16.
+This is handled by coding 8 shell blocks (128 samples) and discarding the final
+ 8 samples of the last block.
+The decoder contains no special case that prevents an encoder from placing
+ pulses in these samples, and they must be correctly parsed from the bitstream
+ if present, but they are otherwise ignored.

+The first symbol in the excitation is a "rate level", which is an index from 0
+ to 8, inclusive, coded using the PDF in <xref target="silk_rate_level_pdfs"/>
+ corresponding to the signal type of the current frame (from
+ <xref target="silk_frame_type"/>).
+The rate level selects the PDF used to decode the number of pulses in
+ the individual shell blocks.
+It does not directly convey any information about the bitrate or the number of
+ pulses itself, but merely changes the probability of the symbols in
+ <xref target="silk_pulse_counts"/>.
+Level 0 provides a more efficient encoding at low rates generally, and
+ level 8 provides a more efficient encoding at high rates generally,
+ though the most efficient level for a particular SILK frame may depend on the
+ exact distribution of the coded symbols.
+An encoder should, but is not required to, use the most efficient rate level.

+The total number of pulses in each of the shell blocks follows the rate level.
+The pulse counts for all of the shell blocks are coded consecutively, before
+ the content of any of the blocks.
+Each block may have anywhere from 0 to 16 pulses, inclusive, coded using the
+ 18-entry PDF in <xref target="silk_pulse_count_pdfs"/> corresponding to the
+ rate level from <xref target="silk_rate_level"/>.
+The special value 17 indicates that this block has one or more additional
+ LSBs to decode for each coefficient.
+If the decoder encounters this value, it decodes another value for the actual
+ pulse count of the block, but uses the PDF corresponding to the special rate
+ level 9 instead of the normal rate level.
+This process repeats until the decoder reads a value less than 17, and it then
+ sets the number of extra LSBs used to the number of 17's decoded for that
+ block.
+If it reads the value 17 ten times, then the next iteration uses the special
+ rate level 10 instead of 9.
+The probability of decoding a 17 when using the PDF for rate level 10 is
+ zero, ensuring that the number of LSBs for a block will not exceed 10.
+The cumulative distribution for rate level 10 is just a shifted version of
+ that for 9 and thus does not require any additional storage.

+<section anchor="silk_pulse_locations" title="Pulse Location Decoding">
+<t>
+The locations of the pulses in each shell block follow the pulse counts,
+ as decoded by silk_shell_decoder() (shell_coder.c).
+As with the pulse counts, these locations are coded for all the shell blocks
+ before any of the remaining information for each block.
+Unlike many other codecs, SILK places no restriction on the distribution of
+ pulses within a shell block.
+All of the pulses may be placed in a single location, or each one in a unique
+ location, or anything in between.
+</t>
+
+<t>
+The location of pulses is coded by recursively partitioning each block into
+ halves, and coding how many pulses fall on the left side of the split.
+All remaining pulses must fall on the right side of the split.
+The process then recurses into the left half, and after that returns, the
+ right half (preorder traversal).
+The PDF to use is chosen by the size of the current partition (16, 8, 4, or 2)
+ and the number of pulses in the partition (1 to 16, inclusive).
+Tables <xref format="counter" target="silk_shell_code3_pdfs"/>
+ through <xref format="counter" target="silk_shell_code0_pdfs"/> list the
+ PDFs used for each partition size and pulse count.
+This process skips partitions without any pulses, i.e., where the initial pulse
+ count from <xref target="silk_pulse_counts"/> was zero, or where the split in
+ the prior level indicated that all of the pulses fell on the other side.
+These partitions have nothing to code, so they require no PDF.

+<section title="Resampling">

+After stereo unmixing (if any), the decoder applies resampling to convert the

+This is necessary when decoding a Hybrid frame at SWB or FB sample rates, or
+ whenever the decoder wants the output at a different sample rate than the
+ internal SILK sampling rate (e.g., to allow a constant sample rate when the
+ audio bandwidth changes, or to allow mixing with audio from other
+ applications).
+The resampler itself is non-normative, and a decoder can use any method it
+ wants to perform the resampling.
+</t>
+
+<t>
+However, a minimum amount of delay is imposed to allow the resampler to
+ operate, and this delay is normative, so that the corresponding delay can be
+ applied to the MDCT layer in the encoder.
+A decoder is always free to use a resampler which requires more delay than
+ allowed for here (e.g., to improve quality), but it must then delay the output
+ of the MDCT layer by this extra amount.
+Keeping as much delay as possible on the encoder side allows an encoder which
+ knows it will never use any of the SILK or Hybrid modes to skip this delay.
+By contrast, if it were all applied by the decoder, then a decoder which
+ processes audio in fixed-size blocks would be forced to delay the output of
+ CELT frames just in case of a later switch to a SILK or Hybrid mode.

+<xref target="silk_resampler_delay_alloc"/> gives the maximum resampler delay

+ samples.
+The reference implementation is able to resample to any of the supported
+ output sampling rates (8, 12, 16, 24, or 48 kHz) within or near this
+ delay constraint.
+Some resampling filters (including those used by the reference implementation)
+ may add a delay that is not an exact integer, or is not linear-phase, and so
+ cannot be represented by a single delay at all frequencies.
+However, such deviations are unlikely to be perceptible, and the comparison
+ tool described in <xref target="conformance"/> is designed to be relatively
+ insensitive to them.

+The decoder extracts information from the range-coded bitstream in the order
+described in <xref target='celt_symbols'/>. In some circumstances, it is
+possible for a decoded value to be out of range due to a very small amount of redundancy
+in the encoding of large integers by the range coder.
+In that case, the decoder should assume there has been an error in the coding,
+decoding, or transmission and SHOULD take measures to conceal the error and/or report
+to the application that a problem has occurred. Such out of range errors cannot occur
+in the SILK layer.
+</t>
+
+<section anchor="transient-decoding" title="Transient Decoding">
+<t>
+The "transient" flag indicates whether the frame uses a single long MDCT or several short MDCTs.
+When it is set, then the MDCT coefficients represent multiple
+short MDCTs in the frame. When not set, the coefficients represent a single
+long MDCT for the frame. The flag is encoded in the bitstream with a probability of 1/8.
+In addition to the global transient flag is a per-band
+binary flag to change the time-frequency (tf) resolution independently in each band. The
+change in tf resolution is defined in tf_select_table[][] in celt.c and depends
+on the frame size, whether the transient flag is set, and the value of tf_select.
+The tf_select flag uses a 1/2 probability, but is only decoded
+if it can have an impact on the result knowing the value of all per-band
+tf_change flags.

+It is important to quantize the energy with sufficient resolution because
+any energy quantization error cannot be compensated for at a later
+stage. Regardless of the resolution used for encoding the spectral shape of a band,
+it is perceptually important to preserve the energy in each band. CELT uses a
+three-step coarse-fine-fine strategy for encoding the energy in the base-2 log
+domain, as implemented in quant_bands.c</t>
+
+<section anchor="coarse-energy-decoding" title="Coarse energy decoding">
+<t>
+Coarse quantization of the energy uses a fixed resolution of 6 dB
+(integer part of base-2 log). To minimize the bitrate, prediction is applied
+both in time (using the previous frame) and in frequency (using the previous
+bands). The part of the prediction that is based on the
+previous frame can be disabled, creating an "intra" frame where the energy
+is coded without reference to prior frames. The decoder first reads the intra flag
+to determine what prediction is used.
+The 2-D z-transform <xref target='z-transform'/> of
+the prediction filter is:

+where b is the band index and l is the frame index. The prediction coefficients
+applied depend on the frame size in use when not using intra energy and are alpha=0, beta=4915/32768
+when using intra energy.
+The time-domain prediction is based on the final fine quantization of the previous
+frame, while the frequency domain (within the current frame) prediction is based
+on coarse quantization only (because the fine quantization has not been computed
+yet). The prediction is clamped internally so that fixed point implementations with
+limited dynamic range always remain in the same state as floating point implementations.
+We approximate the ideal
+probability distribution of the prediction error using a Laplace distribution
+with separate parameters for each frame size in intra- and inter-frame modes. These
+parameters are held in the e_prob_model table in quant_bands.c.
+The
+coarse energy quantization is performed by unquant_coarse_energy() and
+unquant_coarse_energy_impl() (quant_bands.c). The encoding of the Laplace-distributed values is
+implemented in ec_laplace_decode() (laplace.c).

+
+<section anchor="fine-energy-decoding" title="Fine energy quantization">
+<t>
+The number of bits assigned to fine energy quantization in each band is determined
+by the bit allocation computation described in <xref target="allocation"></xref>.
+Let B_i be the number of fine energy bits
+for band i; the refinement is an integer f in the range [0,2**B_i-1]. The mapping between f
+and the correction applied to the coarse energy is equal to (f+1/2)/2**B_i - 1/2. Fine
+energy quantization is implemented in quant_fine_energy() (quant_bands.c).
+</t>
+<t>
+When some bits are left "unused" after all other flags have been decoded, these bits
+are assigned to a "final" step of fine allocation. In effect, these bits are used
+to add one extra fine energy bit per band per channel. The allocation process
+determines two "priorities" for the final fine bits.
+Any remaining bits are first assigned only to bands of priority 0, starting
+from band 0 and going up. If all bands of priority 0 have received one bit per
+channel, then bands of priority 1 are assigned an extra bit per channel,
+starting from band 0. If any bits are left after this, they are left unused.
+This is implemented in unquant_energy_finalise() (quant_bands.c).

+<section anchor="allocation" title="Bit Allocation">
+
+<t>Because the bit allocation drives the decoding of the range-coder
+stream, it MUST be recovered exactly so that identical coding decisions are
+made in the encoder and decoder. Any deviation from the reference's resulting
+bit allocation will result in corrupted output, though implementers are
+free to implement the procedure in any way which produces identical results.</t>
+
+<t>The per-band gain-shape structure of the CELT layer ensures that using
+ the same number of bits for the spectral shape of a band in every frame will
+ result in a roughly constant signal-to-noise ratio in that band.
+This results in coding noise that has the same spectral envelope as the signal.
+The masking curve produced by a standard psychoacoustic model also closely
+ follows the spectral envelope of the signal.
+This structure means that the ideal allocation is more consistent from frame to
+ frame than it is for other codecs without an equivalent structure, and that a
+ fixed allocation provides fairly consistent perceptual
+ performance <xref target='Valin2010'/>.</t>
+
+<t>Many codecs transmit significant amounts of side information to control the
+ bit allocation within a frame.
+Often this control is only indirect, and must be exercised carefully to
+ achieve the desired rate constraints.
+The CELT layer, however, can adapt over a very wide range of rates, and thus
+ has a large number of codebook sizes to choose from for each band.
+Explicitly signaling the size of each of these codebooks would impose
+ considerable overhead, even though the allocation is relatively static from
+ frame to frame.
+This is because all of the information required to compute these codebook sizes
+ must be derived from a single frame by itself, in order to retain robustness
+ to packet loss, so the signaling cannot take advantage of knowledge of the
+ allocation in neighboring frames.
+This problem is exacerbated in low-latency (small frame size) applications,
+ which would include this overhead in every frame.</t>
+
+<t>For this reason, in the MDCT mode Opus uses a primarily implicit bit
+allocation. The available bitstream capacity is known in advance to both
+the encoder and decoder without additional signaling, ultimately from the
+packet sizes expressed by a higher-level protocol. Using this information,
+the codec interpolates an allocation from a hard-coded table.</t>
+
+<t>While the band-energy structure effectively models intra-band masking,
+it ignores the weaker inter-band masking, band-temporal masking, and
+other less significant perceptual effects. While these effects can
+often be ignored, they can become significant for particular samples. One
+mechanism available to encoders would be to simply increase the overall
+rate for these frames, but this is not possible in a constant rate mode
+and can be fairly inefficient. As a result three explicitly signaled
+mechanisms are provided to alter the implicit allocation:</t>
+
+<t>
+<list style="symbols">
+<t>Band boost</t>
+<t>Allocation trim</t>
+<t>Band skipping</t>
+</list>
+</t>
+
+<t>The first of these mechanisms, band boost, allows an encoder to boost
+the allocation in specific bands. The second, allocation trim, works by
+biasing the overall allocation towards higher or lower frequency bands. The third, band
+skipping, selects which low-precision high frequency bands
+will be allocated no shape bits at all.</t>
+
+<t>In stereo mode there are two additional parameters
+potentially coded as part of the allocation procedure: a parameter to allow the
+selective elimination of allocation for the 'side' (i.e., intensity stereo) in jointly coded bands,
+and a flag to deactivate joint coding (i.e., dual stereo). These values are not signaled if
+they would be meaningless in the overall context of the allocation.</t>
+
+<t>Because every signaled adjustment increases overhead and implementation
+complexity, none were included speculatively: the reference encoder makes use
+of all of these mechanisms. While the decision logic in the reference was
+found to be effective enough to justify the overhead and complexity, further
+analysis techniques may be discovered which increase the effectiveness of these
+parameters. As with other signaled parameters, an encoder is free to choose the
+values in any manner, but unless a technique is known to deliver superior
+perceptual results the methods used by the reference implementation should be
+used.</t>
+
+<t>The allocation process consists of the following steps: determining the per-band
+maximum allocation vector, decoding the boosts, decoding the tilt, determining
+the remaining capacity of the frame, searching the mode table for the
+entry nearest but not exceeding the available space (subject to the tilt, boosts, band
+maximums, and band minimums), linear interpolation, reallocation of
+unused bits with concurrent skip decoding, determination of the
+fine-energy vs. shape split, and final reallocation. This process results
+in a per-band shape allocation (in 1/8th bit units), a per-band fine-energy
+allocation (in 1 bit per channel units), a set of band priorities for
+controlling the use of remaining bits at the end of the frame, and a
+remaining balance of unallocated space, which is usually zero except
+at very high rates.</t>
+
+<t>
+The "static" bit allocation (in 1/8 bits) for a quality q, excluding the minimums, maximums,
+tilt and boosts, is equal to channels*N*alloc[band][q]<<LM>>2, where
+alloc[][] is given in <xref target="static_alloc"/> and LM=log2(frame_size/120). The allocation
+is obtained by linearly interpolating between two values of q (in steps of 1/64) to find the
+highest allocation that does not exceed the number of bits remaining.

+
+<t>The maximum allocation vector is an approximation of the maximum space
+that can be used by each band for a given mode. The value is
+approximate because the shape encoding is variable rate (due
+to entropy coding of splitting parameters). Setting the maximum too low reduces the
+maximum achievable quality in a band while setting it too high
+may result in waste: bitstream capacity available at the end
+of the frame which can not be put to any use. The maximums
+specified by the codec reflect the average maximum. In the reference
+implementation, the maximums in bits/sample are precomputed in a static table
+(see cache_caps50[] in static_modes_float.h) for each band,
+for each value of LM, and for both mono and stereo.
+
+Implementations are expected
+to simply use the same table data, but the procedure for generating
+this table is included in rate.c as part of compute_pulse_cache().</t>
+
+<t>To convert the values in cache.caps into the actual maximums: first
+set nbBands to the maximum number of bands for this mode, and stereo to
+zero if stereo is not in use and one otherwise. For each band set N
+to the number of MDCT bins covered by the band (for one channel), set LM
+to the shift value for the frame size,
+then set i to nbBands*(2*LM+stereo). Then set the maximum for the band to
+the i-th index of cache.caps + 64 and multiply by the number of channels
+in the current frame (one or two) and by N, then divide the result by 4
+using integer division. The resulting vector will be called
+cap[]. The elements fit in signed 16-bit integers but do not fit in 8 bits.
+This procedure is implemented in the reference in the function init_caps() in celt.c.
+</t>
+
+<t>The band boosts are represented by a series of binary symbols which
+are entropy coded with very low probability. Each band can potentially be boosted
+multiple times, subject to the frame actually having enough room to obey
+the boost and having enough room to code the boost symbol. The default
+coding cost for a boost starts out at six bits (probability p=1/64), but subsequent boosts
+in a band cost only a single bit and every time a band is boosted the
+initial cost is reduced (down to a minimum of two bits, or p=1/4). Since the initial
+cost of coding a boost is 6 bits, the coding cost of the boost symbols when
+completely unused is 0.48 bits/frame for a 21 band mode (21*-log2(1-1/2**6)).</t>
+
+<t>To decode the band boosts: First set 'dynalloc_logp' to 6, the initial
+amount of storage required to signal a boost in bits, 'total_bits' to the
+size of the frame in 8th bits, 'total_boost' to zero, and 'tell' to the total number
+of 8th bits decoded
+so far. For each band from the coding start (0 normally, but 17 in Hybrid mode)
+to the coding end (which changes depending on the signaled bandwidth), the boost quanta
+in units of 1/8 bit is calculated as quanta = min(8*N, max(48, N)).
+This represents a boost step size of six bits, subject to a lower limit of
+1/8th bit/sample and an upper limit of 1 bit/sample.
+Set 'boost' to zero and 'dynalloc_loop_logp'
+to dynalloc_logp. While dynalloc_loop_log (the current worst case symbol cost) in
+8th bits plus tell is less than total_bits plus total_boost and boost is less than cap[] for this
+band: Decode a bit from the bitstream with a with dynalloc_loop_logp as the cost
+of a one, update tell to reflect the current used capacity, if the decoded value
+is zero break the loop otherwise add quanta to boost and total_boost, subtract quanta from
+total_bits, and set dynalloc_loop_log to 1. When the while loop finishes
+boost contains the boost for this band. If boost is non-zero and dynalloc_logp
+is greater than 2, decrease dynalloc_logp. Once this process has been
+executed on all bands, the band boosts have been decoded. This procedure
+is implemented around line 2474 of celt.c.</t>
+
+<t>At very low rates it is possible that there won't be enough available
+space to execute the inner loop even once. In these cases band boost
+is not possible but its overhead is completely eliminated. Because of the
+high cost of band boost when activated, a reasonable encoder should not be
+using it at very low rates. The reference implements its dynalloc decision
+logic around line 1304 of celt.c.</t>
+
+<t>The allocation trim is a integer value from 0-10. The default value of
+5 indicates no trim. The trim parameter is entropy coded in order to
+lower the coding cost of less extreme adjustments. Values lower than
+5 bias the allocation towards lower frequencies and values above 5
+bias it towards higher frequencies. Like other signaled parameters, signaling
+of the trim is gated so that it is not included if there is insufficient space
+available in the bitstream. To decode the trim, first set
+the trim value to 5, then if and only if the count of decoded 8th bits so far (ec_tell_frac)
+plus 48 (6 bits) is less than or equal to the total frame size in 8th
+bits minus total_boost (a product of the above band boost procedure),
+decode the trim value using the PDF in <xref target="celt_trim_pdf"/>.</t>

+
+<t>For 10 ms and 20 ms frames using short blocks and that have at least LM+2 bits left prior to
+the allocation process, then one anti-collapse bit is reserved in the allocation process so it can
+be decoded later. Following the the anti-collapse reservation, one bit is reserved for skip if available.</t>
+
+<t>For stereo frames, bits are reserved for intensity stereo and for dual stereo. Intensity stereo
+requires ilog2(end-start) bits. Those bits are reserved if there is enough bits left. Following this, one
+bit is reserved for dual stereo if available.</t>
+
+
+<t>The allocation computation begins by setting up some initial conditions.
+'total' is set to the remaining available 8th bits, computed by taking the
+size of the coded frame times 8 and subtracting ec_tell_frac(). From this value, one (8th bit)
+is subtracted to ensure that the resulting allocation will be conservative. 'anti_collapse_rsv'
+is set to 8 (8th bits) if and only if the frame is a transient, LM is greater than 1, and total is
+greater than or equal to (LM+2) * 8. Total is then decremented by anti_collapse_rsv and clamped
+to be equal to or greater than zero. 'skip_rsv' is set to 8 (8th bits) if total is greater than
+8, otherwise it is zero. Total is then decremented by skip_rsv. This reserves space for the
+final skipping flag.</t>
+

+</t>
+
+<t>
+The PLC in

+In CELT mode, the PLC finds a periodicity in the decoded

+cancellation with the previous frame and the next frame. This is implemented

+<section anchor="clock-drift" title="Clock Drift Compensation">
+<t>
+Clock drift refers to the gradual desynchronization of two endpoints
+whose sample clocks run at different frequencies while they are streaming
+live audio. Differences in clock frequencies are generally attributable to
+manufacturing variation in the endpoints' clock hardware. For long-lived
+streams, the time difference between sender and receiver can grow without
+bound.
+</t>
+
+<t>
+When the sender's clock runs slower than the receiver's, the effect is similar
+to packet loss: too few packets are received. The receiver can distinguish
+between drift and loss if the transport provides packet timestamps. A receiver
+for live streams SHOULD conceal the effects of drift, and MAY do so by invoking
+the PLC.
+</t>
+
+<t>
+When the sender's clock runs faster than the receiver's, too many packets will
+be received. The receiver MAY respond by skipping any packet (i.e., not
+submitting the packet for decoding). This is likely to produce a less severe
+artifact than if the frame were dropped after decoding.
+</t>
+
+<t>
+A decoder MAY employ a more sophisticated drift compensation method. For
+example, the
+<xref target='Google-NetEQ'>NetEQ component</xref>
+of the
+<xref target='Google-WebRTC'>Google WebRTC codebase</xref>
+compensates for drift by adding or removing

+Switching between the Opus coding modes, audio bandwidths, and channel counts

+Switching between any two configurations of the CELT-only mode, any two
+ configurations of the Hybrid mode, or from WB SILK to Hybrid mode does not
+ require any special treatment in the decoder, as the MDCT overlap will smooth
+ the transition.
+Switching from Hybrid mode to WB SILK requires adding in the final contents
+ of the CELT overlap buffer to the first SILK-only packet.
+This can be done by decoding a 2.5 ms silence frame with the CELT decoder
+ using the channel count of the SILK-only packet (and any choice of audio
+ bandwidth), which will correctly handle the cases when the channel count
+ changes as well.
+</t>
+
+<t>
+When changing the channel count for SILK-only or Hybrid packets, the encoder
+ can avoid glitches by smoothly varying the stereo width of the input signal
+ before or after the transition, and SHOULD do so.
+However, other transitions between SILK-only packets or between NB or MB SILK
+ and Hybrid packets may cause glitches, because neither the LSF coefficients
+ nor the LTP, LPC, stereo unmixing, and resampler buffers are available at the
+ new sample rate.
+These switches SHOULD be delayed by the encoder until quiet periods or
+ transients, where the inevitable glitches will be less audible. Additionally,
+ the bit-stream MAY include redundant side information ("redundancy"), in the
+ form of additional CELT frames embedded in each of the Opus frames around the

+The other transitions that cannot be easily handled are those where the lower
+ frequencies switch between the SILK LP-based model and the CELT MDCT model.
+However, an encoder may not have an opportunity to delay such a switch to a
+ convenient point.
+For example, if the content switches from speech to music, and the encoder does
+ not have enough latency in its analysis to detect this in advance, there may
+ be no convenient silence period during which to make the transition for quite
+ some time.
+To avoid or reduce glitches during these problematic mode transitions, and

+It would have been possible to avoid these invalid states in the design of Opus
+ by limiting the range of the explicit length decoded from Hybrid frames by the

+However, this would require an encoder to determine the rate allocation for the
+ MDCT layer up front, before it began encoding that layer.
+By allowing some invalid sizes, the encoder is able to defer that decision
+ until much later.
+When encoding Hybrid frames which do not include redundancy, the encoder must
+ still decide up-front if it wishes to use the minimum 37 bits required to
+ trigger encoding of the redundancy flag, but this is a much looser
+ restriction.

+

+After determining the size of the redundant CELT frame, the decoder reduces
+ the size of the buffer currently in use by the range coder by that amount.
+The CELT layer read any raw bits from the end of this reduced buffer, and all

+ this new, reduced size, rather than the original size of the Opus frame.

+Just like the decoder, the Opus encoder also normally consists of two main blocks: the
+SILK encoder and the CELT encoder. However, unlike the case of the decoder, a valid
+(though potentially suboptimal) Opus encoder is not required to support all modes and
+may thus only include a SILK encoder module or a CELT encoder module.
+The output bit-stream of the Opus encoding contains bits from the SILK and CELT
+ encoders, though these are not separable due to the use of a range coder.
+A block diagram of the encoder is illustrated below.

+For a normal encoder where both the SILK and the CELT modules are included, an optimal
+encoder should select which coding mode to use at run-time depending on the conditions.
+In the reference implementation, the frame size is selected by the application, but the
+other configuration parameters (number of channels, bandwidth, mode) are automatically
+selected (unless explicitly overridden by the application) depend on the following:
+<list style="symbols">
+<t>Requested bitrate</t>
+<t>Input sampling rate</t>
+<t>Type of signal (speech vs music)</t>
+<t>Frame size in use</t>
+</list>
+
+The type of signal currently needs to be provided by the application (though it can be
+changed in real-time). An Opus encoder implementation could also do automatic detection,
+but since Opus is an interactive codec, such an implementation would likely have to either
+delay the signal (for non-interactive applications) or delay the mode switching decisions (for
+interactive applications).
+</t>
+
+<t>
+When the encoder is configured for voice over IP applications, the input signal is
+filtered by a high-pass filter to remove the lowest part of the spectrum
+that contains little speech energy and may contain background noise. This is a second order
+Auto Regressive Moving Average (i.e., with poles and zeros) filter with a cut-off frequency around 50 Hz.
+In the future, a music detector may also be used to lower the cut-off frequency when the
+input signal is detected to be music rather than speech.
+</t>
+
+<section anchor="range-encoder" title="Range Encoder">
+<t>
+The range coder acts as the bit-packer for Opus.
+It is used in three different ways: to encode
+<list style="symbols">
+<t>
+Entropy-coded symbols with a fixed probability model using ec_encode()
+ (entenc.c),
+</t>
+<t>
+Integers from 0 to (2**M - 1) using ec_enc_uint() or ec_enc_bits()
+ (entenc.c),</t>
+<t>
+Integers from 0 to (ft - 1) (where ft is not a power of two) using
+ ec_enc_uint() (entenc.c).
+</t>
+</list>
+</t>
+
+<t>
+The range encoder maintains an internal state vector composed of the four-tuple
+ (val, rng, rem, ext) representing the low end of the current
+ range, the size of the current range, a single buffered output byte, and a
+ count of additional carry-propagating output bytes.
+Both val and rng are 32-bit unsigned integer values, rem is a byte value or
+ less than 255 or the special value -1, and ext is an unsigned integer with at
+ least 11 bits.
+This state vector is initialized at the start of each each frame to the value
+ (0, 2**31, -1, 0).
+After encoding a sequence of symbols, the value of rng in the encoder should
+ exactly match the value of rng in the decoder after decoding the same sequence
+ of symbols.
+This is a powerful tool for detecting errors in either an encoder or decoder
+ implementation.
+The value of val, on the other hand, represents different things in the encoder
+ and decoder, and is not expected to match.
+</t>
+
+<t>
+The decoder has no analog for rem and ext.
+These are used to perform carry propagation in the renormalization loop below.
+Each iteration of this loop produces 9 bits of output, consisting of 8 data
+ bits and a carry flag.
+The encoder cannot determine the final value of the output bytes until it
+ propagates these carry flags.
+Therefore the reference implementation buffers a single non-propagating output
+ byte (i.e., one less than 255) in rem and keeps a count of additional
+ propagating (i.e., 255) output bytes in ext.
+An implementation may choose to use any mathematically equivalent scheme to

+The input signal's sampling rate is adjusted by a sample rate conversion
+module so that it matches the SILK internal sampling rate.

+
+<section title='Stereo Mixing'>
+<t>
+The stereo mixer is only used for stereo input signals.
+It converts a stereo left/right signal into an adaptive
+mid/side representation.
+The first step is to compute non-adaptive mid/side signals
+as half the sum and difference between left and right signals.
+The side signal is then minimized in energy by subtracting a
+prediction of it based on the mid signal.
+This prediction works well when the left and right signals
+exhibit linear dependency, for instance for an amplitude-panned
+input signal.
+Like in the decoder, the prediction coefficients are linearly
+interpolated during the first 8 ms of the frame.
+ The mid signal is always encoded, whereas the residual
+ side signal is only encoded if it has sufficient
+ energy compared to the mid signal's energy.
+ If it has not,
+ the "mid_only_flag" is set without encoding the side signal.
+</t>
+<t>
+The predictor coefficients are coded regardless of whether
+the side signal is encoded.
+For each frame, two predictor coefficients are computed, one
+that predicts between low-passed mid and side channels, and
+one that predicts between high-passed mid and side channels.
+The low-pass filter is a simple three-tap filter
+and creates a delay of one sample.
+The high-pass filtered signal is the difference between
+the mid signal delayed by one sample and the low-passed
+signal. Instead of explicitly computing the high-passed
+signal, it is computationally more efficient to transform
+the prediction coefficients before applying them to the
+filtered mid signal, as follows

+The input signal is processed by a Voice Activity Detector (VAD) to produce
+a measure of voice activity, spectral tilt, and signal-to-noise estimates for

+signal into four subbands: 0...Fs/16, Fs/16...Fs/8, Fs/8...Fs/4, and
+Fs/4...Fs/2, where Fs is the sampling frequency (8, 12, 16, or 24 kHz).
+The lowest subband, from 0 - Fs/16, is high-pass filtered with a first-order
+moving average (MA) filter (with transfer function H(z) = 1-z**(-1)) to
+reduce the energy at the lowest frequencies. For each frame, the signal

+The pitch analysis finds a binary voiced/unvoiced classification, and, for
+frames classified as voiced, four pitch lags per frame - one for each
+5 ms subframe - and a pitch correlation indicating the periodicity of
+the signal.
+The input is first whitened using a Linear Prediction (LP) whitening filter,
+where the coefficients are computed through standard Linear Prediction Coding
+(LPC) analysis. The order of the whitening filter is 16 for best results, but

+The whitened signal is analyzed to find pitch lags for which the time
+correlation is high.
+The analysis consists of three stages for reducing the complexity:
+<list style="symbols">
+<t>In the first stage, the whitened signal is downsampled to 4 kHz
+(from 8 kHz) and the current frame is correlated to a signal delayed
+by a range of lags, starting from a shortest lag corresponding to
+500 Hz, to a longest lag corresponding to 56 Hz.</t>
+
+<t>
+The second stage operates on an 8 kHz signal (downsampled from 12, 16,
+or 24 kHz) and measures time correlations only near the lags
+corresponding to those that had sufficiently high correlations in the first
+stage. The resulting correlations are adjusted for a small bias towards
+short lags to avoid ending up with a multiple of the true pitch lag.
+The highest adjusted correlation is compared to a threshold depending on:

+Balancing quantization noise and bitrate.

+Optionally the LPC analysis and noise shaping filters are warped by replacing

+The prediction analysis is performed in one of two ways depending on how
+the pitch estimator classified the frame.
+The processing for voiced and unvoiced speech is described in
+<xref target='pred_ana_voiced_overview_section' /> and
+ <xref target='pred_ana_unvoiced_overview_section' />, respectively.

+
+<section title='Voiced Speech' anchor='pred_ana_voiced_overview_section'>
+<t>
+ For a frame of voiced speech the pitch pulses will remain dominant in the
+ pre-whitened input signal.
+ Further whitening is desirable as it leads to higher quality at the same
+ available bitrate.
+ To achieve this, a Long-Term Prediction (LTP) analysis is carried out to
+ estimate the coefficients of a fifth-order LTP filter for each of four
+ subframes.
+ The LTP coefficients are quantized using the method described in
+ <xref target='ltp_quantizer_overview_section'/>, and the quantized LTP
+ coefficients are used to compute the LTP residual signal.
+ This LTP residual signal is the input to an LPC analysis where the LPC coefficients are
+ estimated using Burg's method <xref target="Burg"/>, such that the residual energy is minimized.
+ The estimated LPC coefficients are converted to a Line Spectral Frequency (LSF) vector
+ and quantized as described in <xref target='lsf_quantizer_overview_section'/>.
+After quantization, the quantized LSF vector is converted back to LPC
+coefficients using the full procedure in <xref target="silk_nlsfs"/>.
+By using quantized LTP coefficients and LPC coefficients derived from the
+quantized LSF coefficients, the encoder remains fully synchronized with the
+decoder.
+The quantized LPC and LTP coefficients are also used to filter the input
+signal and measure residual energy for each of the four subframes.
+</t>
+</section>
+<section title='Unvoiced Speech' anchor='pred_ana_unvoiced_overview_section'>
+<t>
+For a speech signal that has been classified as unvoiced, there is no need
+for LTP filtering, as it has already been determined that the pre-whitened
+input signal is not periodic enough within the allowed pitch period range
+for LTP analysis to be worth the cost in terms of complexity and bitrate.
+The pre-whitened input signal is therefore discarded, and instead the input
+signal is used for LPC analysis using Burg's method.
+The resulting LPC coefficients are converted to an LSF vector and quantized
+as described in the following section.
+They are then transformed back to obtain quantized LPC coefficients, which
+are then used to filter the input signal and measure residual energy for

+</t>
+<section title="Burg's Method">
+<t>
+The main purpose of linear prediction in SILK is to reduce the bitrate by
+minimizing the residual energy.
+At least at high bitrates, perceptual aspects are handled
+independently by the noise shaping filter.
+Burg's method is used because it provides higher prediction gain
+than the autocorrelation method and, unlike the covariance method,
+produces stable filters (assuming numerical errors don't spoil
+that). SILK's implementation of Burg's method is also computationally
+faster than the autocovariance method.
+The implementation of Burg's method differs from traditional
+implementations in two aspects.
+The first difference is that it
+operates on autocorrelations, similar to the Schur algorithm <xref target="Schur"/>, but
+with a simple update to the autocorrelations after finding each
+reflection coefficient to make the result identical to Burg's method.
+This brings down the complexity of Burg's method to near that of
+the autocorrelation method.
+The second difference is that the signal in each subframe is scaled
+by the inverse of the residual quantization step size. Subframes with
+a small quantization step size will on average spend more bits for a
+given amount of residual energy than subframes with a large step size.
+Without scaling, Burg's method minimizes the total residual energy in
+all subframes, which doesn't necessarily minimize the total number of
+bits needed for coding the quantized residual. The residual energy
+of the scaled subframes is a better measure for that number of
+bits.

+<section title='LSF Quantization' anchor='lsf_quantizer_overview_section'>
+<t>
+Unlike many other speech codecs, SILK uses variable bitrate coding
+for the LSFs.
+This improves the average rate-distortion (R-D) tradeoff and reduces outliers.
+The variable bitrate coding minimizes a linear combination of the weighted
+quantization errors and the bitrate.
+The weights for the quantization errors are the Inverse
+Harmonic Mean Weighting (IHMW) function proposed by Laroia et al.
+(see <xref target="laroia-icassp" />).
+These weights are referred to here as Laroia weights.
+</t>
+<t>
+The LSF quantizer consists of two stages.
+The first stage is an (unweighted) vector quantizer (VQ), with a
+codebook size of 32 vectors.
+The quantization errors for the codebook vector are sorted, and
+for the N best vectors a second stage quantizer is run.
+By varying the number N a tradeoff is made between R-D performance
+and computational efficiency.
+For each of the N codebook vectors the Laroia weights corresponding
+to that vector (and not to the input vector) are calculated.
+Then the residual between the input LSF vector and the codebook
+vector is scaled by the square roots of these Laroia weights.
+This scaling partially normalizes error sensitivity for the
+residual vector, so that a uniform quantizer with fixed
+step sizes can be used in the second stage without too much
+performance loss.
+And by scaling with Laroia weights determined from the first-stage
+codebook vector, the process can be reversed in the decoder.
+</t>
+<t>
+The second stage uses predictive delayed decision scalar
+quantization.
+The quantization error is weighted by Laroia weights determined
+from the LSF input vector.
+The predictor multiplies the previous quantized residual value
+by a prediction coefficient that depends on the vector index from the
+first stage VQ and on the location in the LSF vector.
+The prediction is subtracted from the LSF residual value before
+quantizing the result, and added back afterwards.
+This subtraction can be interpreted as shifting the quantization levels
+of the scalar quantizer, and as a result the quantization error of
+each value depends on the quantization decision of the previous value.
+This dependency is exploited by the delayed decision mechanism to
+search for a quantization sequency with best R-D performance
+with a Viterbi-like algorithm <xref target="Viterbi"/>.
+The quantizer processes the residual LSF vector in reverse order
+(i.e., it starts with the highest residual LSF value).
+This is done because the prediction works slightly
+better in the reverse direction.
+</t>
+<t>
+The quantization index of the first stage is entropy coded.
+The quantization sequence from the second stage is also entropy
+coded, where for each element the probability table is chosen
+depending on the vector index from the first stage and the location
+of that element in the LSF vector.
+</t>
+
+<section title='LSF Stabilization' anchor='lsf_stabilizer_overview_section'>
+<t>
+If the input is stable, finding the best candidate usually results in a
+quantized vector that is also stable. Because of the two-stage approach,
+however, it is possible that the best quantization candidate is unstable.
+The encoder applies the same stabilization procedure applied by the decoder
+ (see <xref target="silk_nlsf_stabilization"/> to ensure the LSF parameters
+ are within their valid range, increasingly sorted, and have minimum
+ distances between each other and the border values.

+<section title='LTP Quantization' anchor='ltp_quantizer_overview_section'>
+<t>
+For voiced frames, the prediction analysis described in
+<xref target='pred_ana_voiced_overview_section' /> resulted in four sets
+(one set per subframe) of five LTP coefficients, plus four weighting matrices.
+The LTP coefficients for each subframe are quantized using entropy constrained
+vector quantization.
+A total of three vector codebooks are available for quantization, with
+different rate-distortion trade-offs. The three codebooks have 10, 20, and
+40 vectors and average rates of about 3, 4, and 5 bits per vector, respectively.
+Consequently, the first codebook has larger average quantization distortion at
+a lower rate, whereas the last codebook has smaller average quantization
+distortion at a higher rate.
+Given the weighting matrix W_ltp and LTP vector b, the weighted rate-distortion
+measure for a codebook vector cb_i with rate r_i is give by
+<figure align="center">
+<artwork align="center">
+<![CDATA[
+ RD = u * (b - cb_i)' * W_ltp * (b - cb_i) + r_i,
+]]>
+</artwork>
+</figure>
+where u is a fixed, heuristically-determined parameter balancing the distortion
+and rate.
+Which codebook gives the best performance for a given LTP vector depends on the
+weighting matrix for that LTP vector.
+For example, for a low valued W_ltp, it is advantageous to use the codebook
+with 10 vectors as it has a lower average rate.
+For a large W_ltp, on the other hand, it is often better to use the codebook
+with 40 vectors, as it is more likely to contain the best codebook vector.
+The weighting matrix W_ltp depends mostly on two aspects of the input signal.
+The first is the periodicity of the signal; the more periodic, the larger W_ltp.
+The second is the change in signal energy in the current subframe, relative to
+the signal one pitch lag earlier.
+A decaying energy leads to a larger W_ltp than an increasing energy.
+Both aspects fluctuate relatively slowly, which causes the W_ltp matrices for
+different subframes of one frame often to be similar.
+Because of this, one of the three codebooks typically gives good performance
+for all subframes, and therefore the codebook search for the subframe LTP
+vectors is constrained to only allow codebook vectors to be chosen from the
+same codebook, resulting in a rate reduction.
+</t>
+
+<t>
+To find the best codebook, each of the three vector codebooks is
+used to quantize all subframe LTP vectors and produce a combined
+weighted rate-distortion measure for each vector codebook.
+The vector codebook with the lowest combined rate-distortion
+over all subframes is chosen. The quantized LTP vectors are used
+in the noise shaping quantizer, and the index of the codebook
+plus the four indices for the four subframe codebook vectors
+are passed on to the range encoder.

+The residual signal is multiplied by the inverse quantized quantization gain
+from the noise shaping analysis, and input to a scalar quantizer.
+The quantization indices of the scalar quantizer represent a signal of pulses

+The quantized output signal y(n) is input to the synthesis shaping and

+Optionally the noise shaping quantizer operates in a delayed decision

+In this mode it uses a Viterbi algorithm to keep track of

+
+<section title='Constant Bitrate Mode'>
+<t>
+ SILK was designed to run in Variable Bitrate (VBR) mode. However
+ the reference implementation also has a Constant Bitrate (CBR) mode
+ for SILK. In CBR mode SILK will attempt to encode each packet with
+ no more than the allowed number of bits. The Opus wrapper code
+ then pads the bitstream if any unused bits are left in SILK mode, or

+ The number of payload bits is adjusted by changing

+<section title="CELT Encoder">
+<t>
+Most of the aspects of the CELT encoder can be directly derived from the description
+of the decoder. For example, the filters and rotations in the encoder are simply the
+inverse of the operation performed by the decoder. Similarly, the quantizers generally
+optimize for the mean square error (because noise shaping is part of the bit-stream itself),
+so no special search is required. For this reason, only the less straightforward aspects of the
+encoder are described here.
+</t>
+
+<section anchor="pitch-prefilter" title="Pitch Prefilter">
+<t>The pitch prefilter is applied after the pre-emphasis. It is applied
+in such a way as to be the inverse of the decoder's post-filter. The main non-obvious aspect of the
+prefilter is the selection of the pitch period. The pitch search should be optimized for the
+following criteria:
+<list style="symbols">
+<t>continuity: it is important that the pitch period
+does not change abruptly between frames; and</t>
+<t>avoidance of pitch multiples: when the period used is a multiple of the real period
+(lower frequency fundamental), the post-filter loses most of its ability to reduce noise</t>
+</list>
+</t>
+</section>
+
+<section anchor="normalization" title="Bands and Normalization">
+<t>
+The MDCT output is divided into bands that are designed to match the ear's critical
+bands for the smallest (2.5 ms) frame size. The larger frame sizes use integer
+multiples of the 2.5 ms layout. For each band, the encoder
+computes the energy that will later be encoded. Each band is then normalized by the
+square root of the <spanx style="strong">unquantized</spanx> energy, such that each band now forms a unit vector X.
+The energy and the normalization are computed by compute_band_energies()
+and normalise_bands() (bands.c), respectively.
+</t>
+</section>
+
+<section anchor="energy-quantization" title="Energy Envelope Quantization">
+
+<t>
+Energy quantization (both coarse and fine) can be easily understood from the decoding process.
+For all useful bitrates, the coarse quantizer always chooses the quantized log energy value that
+minimizes the error for each band. Only at very low rate does the encoder allow larger errors to
+minimize the rate and avoid using more bits than are available. When the
+available CPU requirements allow it, it is best to try encoding the coarse energy both with and without
+inter-frame prediction such that the best prediction mode can be selected. The optimal mode depends on
+the coding rate, the available bitrate, and the current rate of packet loss.
+</t>
+
+<t>The fine energy quantizer always chooses the quantized log energy value that
+minimizes the error for each band because the rate of the fine quantization depends only
+on the bit allocation and not on the values that are coded.
+</t>
+</section> <!-- Energy quant -->
+
+<section title="Bit Allocation">
+<t>The encoder must use exactly the same bit allocation process as used by the decoder
+and described in <xref target="allocation"/>. The three mechanisms that can be used by the
+encoder to adjust the bitrate on a frame-by-frame basis are band boost, allocation trim,
+and band skipping.
+</t>
+
+<section title="Band Boost">
+<t>The reference encoder makes a decision to boost a band when the energy of that band is significantly
+higher than that of the neighboring bands. Let E_j be the log-energy of band j, we define
+<list>
+<t>D_j = 2*E_j - E_j-1 - E_j+1 </t>
+</list>
+
+The allocation of band j is boosted once if D_j > t1 and twice if D_j > t2. For LM>=1, t1=2 and t2=4,
+while for LM<1, t1=3 and t2=5.
+</t>
+
+</section>
+
+<section title="Allocation Trim">
+<t>The allocation trim is a value between 0 and 10 (inclusively) that controls the allocation
+balance between the low and high frequencies. The encoder starts with a safe "default" of 5
+and deviates from that default in two different ways. First the trim can deviate by +/- 2
+depending on the spectral tilt of the input signal. For signals with more low frequencies, the
+trim is increased by up to 2, while for signals with more high frequencies, the trim is
+decreased by up to 2.
+For stereo inputs, the trim value can
+be decreased by up to 4 when the inter-channel correlation at low frequency (first 8 bands)
+is high. </t>
+</section>
+
+<section title="Band Skipping">
+<t>The encoder uses band skipping to ensure that the shape of the bands is only coded
+if there is at least 1/2 bit per sample available for the PVQ. If not, then no bit is allocated
+and folding is used instead. To ensure continuity in the allocation, some amount of hysteresis is
+added to the process, such that a band that received PVQ bits in the previous frame only needs 7/16
+bit/sample to be coded for the current frame, while a band that did not receive PVQ bits in the
+previous frames needs at least 9/16 bit/sample to be coded.</t>
+</section>
+
+</section>
+
+<section title="Stereo Decisions">
+<t>Because CELT applies mid-side stereo coupling in the normalized domain, it does not suffer from
+important stereo image problems even when the two channels are completely uncorrelated. For this reason
+it is always safe to use stereo coupling on any audio frame. That being said, there are some frames
+for which dual (independent) stereo is still more efficient. This decision is made by comparing the estimated
+entropy with and without coupling over the first 13 bands, taking into account the fact that all bands with
+more than two MDCT bins require one extra degree of freedom when coded in mid-side. Let L1_ms and L1_lr
+be the L1-norm of the mid-side vector and the L1-norm of the left-right vector, respectively. The decision
+to use mid-side is made if and only if
+<figure align="center">
+<artwork align="center"><![CDATA[
+ L1_ms L1_lr
+-------- < -----
+bins + E bins
+]]></artwork>
+</figure>
+where bins is the number of MDCT bins in the first 13 bands and E is the number of extra degrees of
+freedom for mid-side coding. For LM>1, E=13, otherwise E=5.
+</t>
+
+<t>The reference encoder decides on the intensity stereo threshold based on the bitrate alone. After
+taking into account the frame size by subtracting 80 bits per frame for coarse energy, the first
+band using intensity coding is as follows:
+</t>

+
+<section title="Time-Frequency Decision">
+<t>
+The choice of time-frequency resolution used in <xref target="tf-change"></xref> is based on
+R-D optimization. The distortion is the L1-norm (sum of absolute values) of each band
+after each TF resolution under consideration. The L1 norm is used because it represents the entropy
+for a Laplacian source. The number of bits required to code a change in TF resolution between
+two bands is higher than the cost of having those two bands use the same resolution, which is
+what requires the R-D optimization. The optimal decision is computed using the Viterbi algorithm.
+See tf_analysis() in celt/celt.c.
+</t>
+</section>
+
+<section title="Spreading Values Decision">
+<t>
+The choice of the spreading value in <xref target="spread values"></xref> has an
+impact on the nature of the coding noise introduced by CELT. The larger the f_r value, the
+lower the impact of the rotation, and the more tonal the coding noise. The
+more tonal the signal, the more tonal the noise should be, so the CELT encoder determines
+the optimal value for f_r by estimating how tonal the signal is. The tonality estimate
+is based on discrete pdf (4-bin histogram) of each band. Bands that have a large number of small
+values are considered more tonal and a decision is made by combining all bands with more than
+8 samples. See spreading_decision() in celt/bands.c.

+<section anchor="pvq" title="Spherical Vector Quantization">
+<t>CELT uses a Pyramid Vector Quantization (PVQ) <xref target="PVQ"></xref>
+codebook for quantizing the details of the spectrum in each band that have not
+been predicted by the pitch predictor. The PVQ codebook consists of all sums
+of K signed pulses in a vector of N samples, where two pulses at the same position
+are required to have the same sign. Thus the codebook includes
+all integer codevectors y of N dimensions that satisfy sum(abs(y(j))) = K.
+</t>
+
+<t>
+In bands where there are sufficient bits allocated PVQ is used to encode
+the unit vector that results from the normalization in
+<xref target="normalization"></xref> directly. Given a PVQ codevector y,
+the unit vector X is obtained as X = y/||y||, where ||.|| denotes the
+L2 norm.
+</t>
+
+
+<section anchor="pvq-search" title="PVQ Search">
+
+<t>
+The search for the best codevector y is performed by alg_quant()
+(vq.c). There are several possible approaches to the
+search, with a trade-off between quality and complexity. The method used in the reference

+X onto the codebook pyramid of K-1 pulses:
+</t>
+<t>
+y0 = truncate_towards_zero( (K-1) * X / sum(abs(X)))
+</t>
+
+<t>
+Depending on N, K and the input data, the initial codeword y0 may contain from
+0 to K-1 non-zero values. All the remaining pulses, with the exception of the last one,
+are found iteratively with a greedy search that minimizes the normalized correlation
+between y and X:

+<section anchor="conformance" title="Conformance">
+
+<t>
+It is our intention to allow the greatest possible choice of freedom in
+implementing the specification. For this reason, outside of the exceptions
+noted in this section, conformance is defined through the reference
+implementation of the decoder provided in <xref target="ref-implementation"/>.
+Although this document includes an English description of the codec, should
+the description contradict the source code of the reference implementation,
+the latter shall take precedence.
+</t>
+
+<t>
+Compliance with this specification means that in addition to following the normative keywords in this document,
+ a decoder's output MUST also be
+ within the thresholds specified by the opus_compare.c tool (included
+ with the code) when compared to the reference implementation for each of the
+ test vectors provided (see <xref target="test-vectors"></xref>) and for each output
+ sampling rate and channel count supported. In addition, a compliant
+ decoder implementation MUST have the same final range decoder state as that of the
+ reference decoder. It is therefore RECOMMENDED that the
+ decoder implement the same functional behavior as the reference.
+
+ A decoder implementation is not required to support all output sampling
+ rates or all output channel counts.
+</t>
+
+<section title="Testing">
+<t>
+Using the reference code provided in <xref target="ref-implementation"></xref>,
+a test vector can be decoded with
+<list>
+<t>opus_demo -d <rate> <channels> testvectorX.bit testX.out</t>
+</list>
+where <rate> is the sampling rate and can be 8000, 12000, 16000, 24000, or 48000, and
+<channels> is 1 for mono or 2 for stereo.
+</t>
+
+<t>
+If the range decoder state is incorrect for one of the frames, the decoder will exit with
+"Error: Range coder state mismatch between encoder and decoder". If the decoder succeeds, then
+the output can be compared with the "reference" output with
+<list>
+<t>opus_compare -s -r <rate> testvectorX.dec testX.out</t>
+</list>
+for stereo or
+<list>
+<t>opus_compare -r <rate> testvectorX.dec testX.out</t>
+</list>
+for mono.
+</t>
+
+<t>In addition to indicating whether the test vector comparison passes, the opus_compare tool
+outputs an "Opus quality metric" that indicates how well the tested decoder matches the
+reference implementation. A quality of 0 corresponds to the passing threshold, while
+a quality of 100 is the highest possible value and means that the output of the tested decoder is identical to the reference
+implementation. The passing threshold (quality 0) was calibrated in such a way that it corresponds to
+additive white noise with a 48 dB SNR (similar to what can be obtained on a cassette deck).
+It is still possible for an implementation to sound very good with such a low quality measure
+(e.g. if the deviation is due to inaudible phase distortion), but unless this is verified by
+listening tests, it is RECOMMENDED that implementations achieve a quality above 90 for 48 kHz
+decoding. For other sampling rates, it is normal for the quality metric to be lower
+(typically as low as 50 even for a good implementation) because of harmless mismatch with
+the delay and phase of the internal sampling rate conversion.
+</t>
+
+<t>
+On POSIX environments, the run_vectors.sh script can be used to verify all test
+vectors. This can be done with

+<section anchor="opus-custom" title="Opus Custom">
+<t>
+Opus Custom is an OPTIONAL part of the specification that is defined to
+handle special sample rates and frame rates that are not supported by the
+main Opus specification. Use of Opus Custom is discouraged for all but very
+special applications for which a frame size different from 2.5, 5, 10, or 20 ms is
+needed (for either complexity or latency reasons). Because Opus Custom is
+optional, streams encoded using Opus Custom cannot be expected to be decodable by all Opus
+implementations. Also, because no in-band mechanism exists for specifying the sampling
+rate and frame size of Opus Custom streams, out-of-band signaling is required.
+In Opus Custom operation, only the CELT layer is available, using the opus_custom_* function
+calls in opus_custom.h.

+
+</section>
+
+<section anchor="security" title="Security Considerations">
+
+<t>
+Implementations of the Opus codec need to take appropriate security considerations
+into account, as outlined in <xref target="DOS"/>.
+It is extremely important for the decoder to be robust against malicious
+payloads.
+Malicious payloads must not cause the decoder to overrun its allocated memory
+ or to take an excessive amount of resources to decode.
+Although problems
+in encoders are typically rarer, the same applies to the encoder. Malicious
+audio streams must not cause the encoder to misbehave because this would
+allow an attacker to attack transcoding gateways.
+</t>
+<t>
+The reference implementation contains no known buffer overflow or cases where
+ a specially crafted packet or audio segment could cause a significant increase
+ in CPU load.
+However, on certain CPU architectures where denormalized floating-point
+ operations are much slower than normal floating-point operations, it is
+ possible for some audio content (e.g., silence or near-silence) to cause an
+ increase in CPU load.
+Denormals can be introduced by reordering operations in the compiler and depend
+ on the target architecture, so it is difficult to guarantee that an implementation
+ avoids them.
+For architectures on which denormals are problematic, adding very small
+ floating-point offsets to the affected signals to prevent significant numbers
+ of denormalized operations is RECOMMENDED.
+Alternatively, it is often possible to configure the hardware to treat
+ denormals as zero (DAZ).
+No such issue exists for the fixed-point reference implementation.
+</t>
+<t>The reference implementation was validated in the following conditions:
+<list style="numbers">
+<t>
+Sending the decoder valid packets generated by the reference encoder and
+ verifying that the decoder's final range coder state matches that of the

+<t>

+</t>
+<t>Sending the decoder random packets.</t>
+<t>
+Sending the decoder packets generated by a version of the reference encoder
+ modified to make random coding decisions (internal fuzzing), including mode
+ switching, and verifying that the range coder final states match.

+In all of the conditions above, both the encoder and the decoder were run
+ inside the <xref target="Valgrind">Valgrind</xref> memory

+<section anchor="ref-implementation" title="Reference Implementation">
+
+<t>This appendix contains the complete source code for the
+reference implementation of the Opus codec written in C. By default,
+this implementation relies on floating-point arithmetic, but it can be
+compiled to use only fixed-point arithmetic by defining the FIXED_POINT
+macro. Information on building and using the reference implementation is
+available in the README file.
+</t>
+
+<t>The implementation can be compiled with either a C89 or a C99
+compiler. It is reasonably optimized for most platforms such that
+only architecture-specific optimizations are likely to be useful.
+The FFT <xref target="FFT"/> used is a slightly modified version of the KISS-FFT library,
+but it is easy to substitute any other FFT library.
+</t>
+
+<t>
+While the reference implementation does not rely on any
+<spanx style="emph">undefined behavior</spanx> as defined by C89 or C99,
+it relies on common <spanx style="emph">implementation-defined behavior</spanx>
+for two's complement architectures:
+<list style="symbols">
+<t>Right shifts of negative values are consistent with two's complement arithmetic, so that a>>b is equivalent to floor(a/(2**b)),</t>
+<t>For conversion to a signed integer of N bits, the value is reduced modulo 2**N to be within range of the type,</t>
+<t>The result of integer division of a negative value is truncated towards zero, and</t>
+<t>The compiler provides a 64-bit integer type (a C99 requirement which is supported by most C89 compilers).</t>
+</list>
+</t>
+
+<t>
+In its current form, the reference implementation also requires the following
+architectural characteristics to obtain acceptable performance:
+<list style="symbols">
+<t>Two's complement arithmetic,</t>
+<t>At least a 16 bit by 16 bit integer multiplier (32-bit result), and</t>
+<t>At least a 32-bit adder/accumulator.</t>

+<xref target="Vectors-website"/>. These test vectors were created specifically to exercise

+
+<section anchor="self-delimiting-framing" title="Self-Delimiting Framing">
+<t>
+To use the internal framing described in <xref target="modes"/>, the decoder
+ must know the total length of the Opus packet, in bytes.
+This section describes a simple variation of that framing which can be used
+ when the total length of the packet is not known.
+Nothing in the encoding of the packet itself allows a decoder to distinguish
+ between the regular, undelimited framing and the self-delimiting framing
+ described in this appendix.
+Which one is used and where must be established by context at the transport
+ layer.
+It is RECOMMENDED that a transport layer choose exactly one framing scheme,
+ rather than allowing an encoder to signal which one it wants to use.
+</t>
+
+<t>
+For example, although a regular Opus stream does not support more than two
+ channels, a multi-channel Opus stream may be formed from several one- and
+ two-channel streams.
+To pack an Opus packet from each of these streams together in a single packet
+ at the transport layer, one could use the self-delimiting framing for all but
+ the last stream, and then the regular, undelimited framing for the last one.
+Reverting to the undelimited framing for the last stream saves overhead
+ (because the total size of the transport-layer packet will still be known),
+ and ensures that a "multi-channel" stream which only has a single Opus stream
+ uses the same framing as a regular Opus stream does.
+This avoids the need for signaling to distinguish these two cases.
+</t>
+
+<t>
+The self-delimiting framing is identical to the regular, undelimited framing
+ from <xref target="modes"/>, except that each Opus packet contains one extra
+ length field, encoded using the same one- or two-byte scheme from
+ <xref target="frame-length-coding"/>.
+This extra length immediately precedes the compressed data of the first Opus
+ frame in the packet, and is interpreted in the various modes as follows:
+<list style="symbols">
+<t>
+Code 0 packets: It is the length of the single Opus frame (see
+ <xref target="sd_code0_packet"/>).
+</t>
+<t>
+Code 1 packets: It is the length used for both of the Opus frames (see
+ <xref target="sd_code1_packet"/>).
+</t>
+<t>
+Code 2 packets: It is the length of the second Opus frame (see
+ <xref target="sd_code2_packet"/>).</t>
+<t>
+CBR Code 3 packets: It is the length used for all of the Opus frames (see
+ <xref target="sd_code3cbr_packet"/>).
+</t>
+<t>VBR Code 3 packets: It is the length of the last Opus frame (see
+ <xref target="sd_code3vbr_packet"/>).

+ <section title='Opus Codec'>
+ <t>
+ Opus encodes speech
+ signals as well as general audio signals. Two different modes can be
+ chosen, a voice mode or an audio mode, to allow the most efficient coding
+ depending on the type of the input signal, the sampling frequency of the
+ input signal, and the intended application.
+ </t>
+
+ <t>
+ The voice mode allows efficient encoding of voice signals at lower bit
+ rates while the audio mode is optimized for general audio signals at medium and
+ higher bitrates.
+ </t>
+
+ <t>
+ Opus is highly scalable in terms of audio
+ bandwidth, bitrate, and complexity. Further, Opus allows
+ transmitting stereo signals with in-band signaling in the bit-stream.
+ </t>
+
+ <section title='Network Bandwidth'>
+ <t>
+ Opus supports bitrates from 6 kb/s to 510 kb/s.
+ The bitrate can be changed dynamically within that range.
+ All
+ other parameters being
+ equal, higher bitrates result in higher audio quality.
+ </t>
+ <section title='Recommended Bitrate' anchor='bitrate_by_bandwidth'>
+ <t>
+ For a frame size of
+ 20 ms, these
+ are the bitrate "sweet spots" for Opus in various configurations:
+
+ <list style="symbols">
+ <t>8-12 kb/s for NB speech,</t>
+ <t>16-20 kb/s for WB speech,</t>
+ <t>28-40 kb/s for FB speech,</t>
+ <t>48-64 kb/s for FB mono music, and</t>
+ <t>64-128 kb/s for FB stereo music.</t>
+ </list>
+ </t>
+ </section>
+ <section title='Variable versus Constant Bitrate' anchor='variable-vs-constant-bitrate'>
+ <t>
+ For the same average bitrate, variable bitrate (VBR) can achieve higher audio quality
+ than constant bitrate (CBR). For the majority of voice transmission applications, VBR
+ is the best choice. One reason for choosing CBR is the potential
+ information leak that <spanx style='emph'>might</spanx> occur when encrypting the
+ compressed stream. See <xref target="RFC6562"/> for guidelines on when VBR is
+ appropriate for encrypted audio communications. In the case where an existing
+ VBR stream needs to be converted to CBR for security reasons, then the Opus padding
+ mechanism described in <xref target="RFC6716"/> is the RECOMMENDED way to achieve padding
+ because the RTP padding bit is unencrypted.</t>
+
+ <t>
+ The bitrate can be adjusted at any point in time. To avoid congestion,
+ the average bitrate SHOULD NOT exceed the available
+ network bandwidth. If no target bitrate is specified, the bitrates specified in
+ <xref target='bitrate_by_bandwidth'/> are RECOMMENDED.
+ </t>
+
+ </section>
+
+ <section title='Discontinuous Transmission (DTX)'>
+
+ <t>
+ Opus can, as described in <xref target='variable-vs-constant-bitrate'/>,
+ be operated with a variable bitrate. In that case, the encoder will
+ automatically reduce the bitrate for certain input signals, like periods
+ of silence. When using continuous transmission, it will reduce the
+ bitrate when the characteristics of the input signal permit, but
+ will never interrupt the transmission to the receiver. Therefore, the
+ received signal will maintain the same high level of audio quality over the
+ full duration of a transmission while minimizing the average bit
+ rate over time.
+ </t>
+
+ <t>
+ In cases where the bitrate of Opus needs to be reduced even
+ further or in cases where only constant bitrate is available,
+ the Opus encoder can use discontinuous
+ transmission (DTX), where parts of the encoded signal that
+ correspond to periods of silence in the input speech or audio signal
+ are not transmitted to the receiver. A receiver can distinguish
+ between DTX and packet loss by looking for gaps in the sequence
+ number, as described by Section 4.1
+ of <xref target="RFC3551"/>.
+ </t>
+
+ <t>
+ On the receiving side, the non-transmitted parts will be handled by a
+ frame loss concealment unit in the Opus decoder which generates a
+ comfort noise signal to replace the non transmitted parts of the
+ speech or audio signal. Use of <xref target="RFC3389"/> Comfort
+ Noise (CN) with Opus is discouraged.
+ The transmitter MUST drop whole frames only,
+ based on the size of the last transmitted frame,
+ to ensure successive RTP timestamps differ by a multiple of 120 and
+ to allow the receiver to use whole frames for concealment.
+ </t>
+
+ <t>
+ DTX can be used with both variable and constant bitrate.
+ It will have a slightly lower speech or audio
+ quality than continuous transmission. Therefore, using continuous
+ transmission is RECOMMENDED unless constraints on available network bandwidth
+ are severe.
+ </t>
+
+ </section>
+
+ </section>
+
+ <section title='Complexity'>
+
+ <t>
+ Complexity of the encoder can be scaled to optimize for CPU resources in real-time, mostly as
+ a trade-off between audio quality and bitrate. Also, different modes of Opus have different complexity.
+ </t>
+
+ </section>
+
+ <section title="Forward Error Correction (FEC)">
+
+ <t>
+ The voice mode of Opus allows for embedding "in-band" forward error correction (FEC)
+ data into the Opus bit stream. This FEC scheme adds
+ redundant information about the previous packet (N-1) to the current
+ output packet N. For
+ each frame, the encoder decides whether to use FEC based on (1) an
+ externally-provided estimate of the channel's packet loss rate; (2) an
+ externally-provided estimate of the channel's capacity; (3) the
+ sensitivity of the audio or speech signal to packet loss; (4) whether
+ the receiving decoder has indicated it can take advantage of "in-band"
+ FEC information. The decision to send "in-band" FEC information is
+ entirely controlled by the encoder and therefore no special precautions
+ for the payload have to be taken.
+ </t>
+
+ <t>
+ On the receiving side, the decoder can take advantage of this
+ additional information when it loses a packet and the next packet
+ is available. In order to use the FEC data, the jitter buffer needs
+ to provide access to payloads with the FEC data.
+ Instead of performing loss concealment for a missing packet, the
+ receiver can then configure its decoder to decode the FEC data from the next packet.
+ </t>
+
+ <t>
+ Any compliant Opus decoder is capable of ignoring
+ FEC information when it is not needed, so encoding with FEC cannot cause
+ interoperability problems.
+ However, if FEC cannot be used on the receiving side, then FEC
+ SHOULD NOT be used, as it leads to an inefficient usage of network
+ resources. Decoder support for FEC SHOULD be indicated at the time a
+ session is set up.
+ </t>
+
+ </section>
+
+ <section title='Stereo Operation'>
+
+ <t>
+ Opus allows for transmission of stereo audio signals. This operation
+ is signaled in-band in the Opus bit-stream and no special arrangement
+ is needed in the payload format. An
+ Opus decoder is capable of handling a stereo encoding, but an
+ application might only be capable of consuming a single audio
+ channel.
+ </t>
+ <t>
+ If a decoder cannot take advantage of the benefits of a stereo signal
+ this SHOULD be indicated at the time a session is set up. In that case
+ the sending side SHOULD NOT send stereo signals as it leads to an
+ inefficient usage of network resources.
+ </t>
+

+
+ <section title='Opus RTP Payload Format' anchor='opus-rtp-payload-format'>
+ <t>The payload format for Opus consists of the RTP header and Opus payload
+ data.</t>
+ <section title='RTP Header Usage'>
+ <t>The format of the RTP header is specified in <xref target="RFC3550"/>.
+ The use of the fields of the RTP header by the Opus payload format is
+ consistent with that specification.</t>
+
+ <t>The payload length of Opus is an integer number of octets and
+ therefore no padding is necessary. The payload MAY be padded by an
+ integer number of octets according to <xref target="RFC3550"/>,
+ although the Opus internal padding is preferred.</t>
+
+ <t>The timestamp, sequence number, and marker bit (M) of the RTP header

+
+ <t>The RTP payload type for Opus is to be assigned dynamically.</t>
+

+
+ <t>Opus supports 5 different audio bandwidths, which can be adjusted during
+ a stream.
+ The RTP timestamp is incremented with a 48000 Hz clock rate
+ for all modes of Opus and all sampling rates.
+ The unit
+ for the timestamp is samples per single (mono) channel. The RTP timestamp corresponds to the
+ sample time of the first encoded sample in the encoded frame.
+ For data encoded with sampling rates other than 48000 Hz,
+ the sampling rate has to be adjusted to 48000 Hz.</t>

+
+ <section title='Payload Structure'>
+ <t>
+ The Opus encoder can output encoded frames representing 2.5, 5, 10, 20,
+ 40, or 60 ms of speech or audio data. Further, an arbitrary number of frames can be
+ combined into a packet, up to a maximum packet duration representing
+ 120 ms of speech or audio data. The grouping of one or more Opus

+ <section title='SDP Offer/Answer Considerations'>
+
+ <t>When using the offer-answer procedure described in <xref
+ target="RFC3264"/> to negotiate the use of Opus, the following
+ considerations apply:</t>
+
+ <t><list style="symbols">
+
+ <t>Opus supports several clock rates. For signaling purposes only
+ the highest, i.e. 48000, is used. The actual clock rate of the
+ corresponding media is signaled inside the payload and is not
+ restricted by this payload format description. The decoder MUST be
+ capable of decoding every received clock rate. An example
+ is shown below:
+

+ </t>
+
+ <t>The "ptime" and "maxptime" parameters are unidirectional
+ receive-only parameters and typically will not compromise
+ interoperability; however, some values might cause application
+ performance to suffer. <xref
+ target="RFC3264"/> defines the SDP offer-answer handling of the
+ "ptime" parameter. The "maxptime" parameter MUST be handled in the
+ same way.</t>
+
+ <t>
+ The "maxplaybackrate" parameter is a unidirectional receive-only
+ parameter that reflects limitations of the local receiver. When
+ sending to a single destination, a sender MUST NOT use an audio
+ bandwidth higher than necessary to make full use of audio sampled at
+ a sampling rate of "maxplaybackrate". Gateways or senders that
+ are sending the same encoded audio to multiple destinations
+ SHOULD NOT use an audio bandwidth higher than necessary to
+ represent audio sampled at "maxplaybackrate", as this would lead
+ to inefficient use of network resources.
+ The "maxplaybackrate" parameter does not
+ affect interoperability. Also, this parameter SHOULD NOT be used
+ to adjust the audio bandwidth as a function of the bitrate, as this
+ is the responsibility of the Opus encoder implementation.
+ </t>
+
+ <t>The "maxaveragebitrate" parameter is a unidirectional receive-only
+ parameter that reflects limitations of the local receiver. The sender

+
+ <t>
+ The "stereo" parameter is a unidirectional receive-only
+ parameter. When sending to a single destination, a sender MUST
+ NOT use stereo when "stereo" is 0. Gateways or senders that are

+
+ <t>For declarative use of SDP such as in Session Announcement Protocol

+ Opus, the following needs to be considered:</t>

+
+ <t>The values for "maxptime", "ptime", "maxplaybackrate", and
+ "maxaveragebitrate" ought to be selected carefully to ensure that a

+
+ <t>
+ The values for "maxptime", "ptime", and of the payload
+ format configuration are recommendations by the decoding side to ensure
+ the best performance for the decoder.
+ </t>
+
+ <t>All other parameters of the payload format configuration are declarative
+ and a participant MUST use the configurations that are provided for
+ the session. More than one configuration can be provided if necessary
+ by declaring multiple RTP payload types; however, the number of types
+ ought to be kept small.</t>

+
+ <t>Use of variable bitrate (VBR) is subject to the security considerations in
+ <xref target="RFC6562"/>.</t>
+
+ <t>RTP packets using the payload format defined in this specification
+ are subject to the security considerations discussed in the RTP

+ However, as "Securing the RTP Protocol Framework:

+ <xref target="RFC7202"/> discusses, it is not an RTP payload
+ format's responsibility to discuss or mandate what solutions are used
+ to meet the basic security goals like confidentiality, integrity and
+ source authenticity for RTP in general. This responsibility lays on
+ anyone using RTP in an application. They can find guidance on
+ available security mechanisms and important considerations in Options
+ for Securing RTP Sessions [I-D.ietf-avtcore-rtp-security-options].
+ Applications SHOULD use one or more appropriate strong security

+4 Design Rules of Encapsulation
+ 4.1 File Type Indentification<a name="4.1"></a>
+ This specification does not define any brand to declare files are conformant to this specification. However,
+ files conformant 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.
+ As an example, the minimal support of the encapsulation of Opus bitstreams in ISO Base Media file format requires
+ the 'iso2' brand in the compatible brands list since support of roll groups is required.
+<a name="4.2"></a>
+ 4.2 Overview of Track Structure
+ This clause summarizes requirements of the encapsulation of Opus coded bitstream as media data in audio tracks
+ in file formats compliant with the ISO Base Media File Format. The details are described in clauses after this
+ clause.
+ + 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 'Opus'.
+ This specification does not define any encapsulation using MP4AudioSampleEntry with objectTypeIndication
+ specified by the MPEG-4 Registration Authority (http://www.mp4ra.org/).
+ See 4.3.1 Sample entry format to get the details about the sample entry.
+ + The 'dOps' box is added to the sample entry to convey initializing information for the decoder.
+ See 4.3.2 Opus Specific Box to get the details.
+ + An Opus sample is exactly one Opus packet for each of different Opus bitstreams.
+ See 4.3.3 Sample format to get the details.
+ + Every Opus sample is a sync sample but requires pre-roll for every random access to get correct output.
+ See 4.3.6 Random Access to get the details.
+<a name="4.3"></a>
+ 4.3 Definitions of Opus sample
+ 4.3.1 Sample entry format<a name="4.3.1"></a>
+ For any track containing Opus bitstreams, at least one sample entry describing corresponding Opus bitstream
+ shall be present inside the Sample Table Box. This version of the specification defines only one sample
+ entry format named OpusSampleEntry whose codingname is 'Opus'. This sample entry includes exactly one Opus
+ Specific Box defined in 4.3.2 as a mandatory box and indicates that Opus samples described by this sample
+ entry are stored by the sample format described in 4.3.3.
+
+ The syntax and semantics of the OpusSampleEntry is shown as follows.
+
+ class OpusSampleEntry() extends AudioSampleEntry ('Opus'){
+ OpusSpecificBox();
+ }
+
+ + channelcount:
+ The channelcount field shall be set to the sum of the total number of Opus bitstreams and the number
+ of Opus bitstreams producing two channels. This value is indentical with (M+N), where M is the value of
+ the *Coupled Stream Count* field and N is the value of the *Stream Count* field in the *Channel Mapping
+ Table* in the identification header defined in Ogg Opus [3].
+ + samplesize:
+ The samplesize field shall be set to 16.
+ + samplerate:
+ The samplerate field shall be set to 48000<<16.
+ + OpusSpecificBox
+ This box contains initializing information for the decoder as defined in 4.3.2.
+
+ 4.3.2 Opus Specific Box<a name="4.3.2"></a>
+ Exactly one Opus Specific Box shall be present in each OpusSampleEntry.
+ The Opus Specific Box contains the Version field and this specification defines version 0 of this box.
+ If incompatible changes occured in the fields after the Version field within the OpusSpecificBox in the
+ future versions of this specification, another version will be defined.
+ This box refers to Ogg Opus [3] at many parts but all the data are stored as big-endian format.
+
+ The syntax and semantics of the Opus Specific Box is shown as follows.
+
+ class ChannelMappingTable (unsigned int(8) OutputChannelCount){
+ unsigned int(8) StreamCount;
+ unsigned int(8) CoupledCount;
+ unsigned int(8 * OutputChannelCount) ChannelMapping;
+ }
+
+ aligned(8) class OpusSpecificBox extends Box('dOps'){
+ unsigned int(8) Version;
+ unsigned int(8) OutputChannelCount;
+ unsigned int(16) PreSkip;
+ unsigned int(32) InputSampleRate;
+ signed int(16) OutputGain;
+ unsigned int(8) ChannelMappingFamily;
+ if (ChannelMappingFamily != 0) {
+ ChannelMappingTable(OutputChannelCount);
+ }
+ }
+
+ + 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 OpusSpecificBox.
+ + OutputChannelCount:
+ The OutputChannelCount field shall be set to the same value as the *Output Channel Count* field in the
+ identification header defined in Ogg Opus [3].
+ + PreSkip:
+ The PreSkip field indicates the number of the priming samples, that is, the number of samples at 48000 Hz
+ to discard from the decoder output when starting playback. The value of the PreSkip field shall be at least
+ 80 milliseconds' worth of PCM samples even when removing any number of Opus samples which may or may not
+ contain the priming samples. The PreSkip field is not used for discarding the priming samples at the whole
+ playback at all since it is informative only, and that task falls on the Edit List Box.
+ + InputSampleRate:
+ The InputSampleRate field shall be set to the same value as the *Input Sample Rate* field in the
+ identification header defined in Ogg Opus [3].
+ + OutputGain:
+ The OutputGain field shall be set to the same value as the *Output Gain* field in the identification
+ header define in Ogg Opus [3]. Note that the value is stored as 8.8 fixed-point.
+ + ChannelMappingFamily:
+ The ChannelMappingFamily field shall be set to the same value as the *Channel Mapping Family* field in
+ the identification header defined in Ogg Opus [3].
+ + StreamCount:
+ The StreamCount field shall be set to the same value as the *Stream Count* field in the identification
+ header defined in Ogg Opus [3].
+ + CoupledCount:
+ The CoupledCount field shall be set to the same value as the *Coupled Count* field in the identification
+ header defined in Ogg Opus [3].
+ + ChannelMapping:
+ The ChannelMapping field shall be set to the same octet string as *Channel Mapping* field in the identi-
+ fication header defined in Ogg Opus [3].
+
+ 4.3.3 Sample format<a name="4.3.3"></a>
+ An Opus sample is exactly one Opus packet for each of different Opus bitstreams. Due to support more than
+ two channels, an Opus sample can contain frames from multiple Opus bitstreams but all Opus packets shall
+ share with the total of frame sizes in a single Opus sample. The way of how to pack an Opus packet from
+ each of Opus bitstreams into a single Opus sample follows Appendix B. in RFC 6716 [2].
+ The endianness has nothing to do with any Opus sample since every Opus packet is processed byte-by-byte.
+ In this specification, 'sample' means 'Opus sample' except for 'padded samples', 'priming samples', 'valid
+ sample' and 'sample-accurate', i.e. 'sample' is 'sample' in the term defined in ISO/IEC 14496-12 [1].

+
+ Figure 1 - Example structure of an Opus sample containing two Opus bitstreams
+
+ 4.3.4 Duration of Opus sample<a name="4.3.4"></a>
+ The duration of Opus sample is given by multiplying the total of frame sizes for a single Opus bitstream
+ expressed in seconds by the value of the timescale field in the Media Header Box.
+ Let's say an Opus sample consists of two Opus bitstreams, where the frame size of one bitstream is 40 milli-
+ seconds and the frame size of another is 60 milliseconds, and the timescale field in the Media Header Box
+ is set to 48000, then the duration of that Opus sample shall be 120 milliseconds since three 40 millisecond
+ frame and two 60 millisecond frames shall be contained because of the maximum duration of Opus packet, 120
+ milliseconds, and 5760 in the timescale indicated in the Media Header Box.
+
+ To indicate the valid samples excluding the padded samples at the end of Opus bitstream, the duration of
+ the last Opus sample of an Opus bitstream is given by multiplying the number of the valid samples by the
+ value produced by dividing the value of the timescale field in the Media Header Box by 48000.
+
+ 4.3.5 Sub-sample<a name="4.3.5"></a>
+ The structure of the last Opus packet in an Opus sample is different from the others in the same Opus sample,
+ and the others are invalid Opus packets as an Opus sample because of self-delimiting framing. To avoid
+ complexities, sub-sample is not defined for Opus sample in this specification.
+
+ 4.3.6 Random Access<a name="4.3.6"></a>
+ This subclause describes the nature of the random access of Opus sample.
+
+ 4.3.6.1 Random Access Point<a name="4.3.6.1"></a>
+ All Opus samples can be independently decoded i.e. every Opus sample is a sync sample. Therefore, the
+ Sync Sample Box shall not be present as long as there are no samples other than Opus samples in the same
+ track. And the sample_is_non_sync_sample field for Opus samples shall be set to 0.
+
+ 4.3.6.2 Pre-roll<a name="4.3.6.2"></a>
+ Opus bitstream requires at least 80 millisecond pre-roll after each random access to get correct output.
+ Pre-roll is indicated by the roll_distance field in AudioRollRecoveryEntry. AudioPreRollEntry shall not
+ be used since every Opus sample is a sync sample in Opus bitstream. Note that roll_distance is expressed
+ in sample units in a term of ISO Base Media File Format, and always takes negative values.
+
+ For any track containing Opus bitstreams, at least one Sample Group Description Box and at least one
+ Sample to Group Box within the Sample Table Box shall be present and these have the grouping_type field
+ set to 'roll'. If any Opus sample is contained in a track fragment, the Sample to Group Box with the
+ grouping_type field set to 'roll' shall be present for that track fragment.
+
+ For the requirement of AudioRollRecoveryEntry, the compatible_brands field in the File Type Box shall
+ contain at least one brand which requires support for roll groups.
+<a name="4.4"></a>
+ 4.4 Trimming of Actual Duration
+ Due to the priming samples (or the padding at the beginning) derived from the pre-roll for the startup and the
+ padded samples at the end, we need trim from media to get the actual duration. An edit in the Edit List Box can
+ achieve this demand, and the Edit Box and the Edit List Box shall be present.
+
+ For sample-accurate trimming, proper timescale should be set to the timescale field in the Movie Header Box
+ and the Media Header Box inside Track Box(es) for Opus bitstream. The timescale field in the Media Header Box is
+ typically set to 48000. It is recommended that the timescale field in the Movie Header Box be set to the same
+ value of the timescale field in the Media Header Box in order to avoid the rounding problem when specifying
+ duration of edit if the timescales in all of the Media Header Boxes are set to the same value.
+
+ For example, to indicate the actual duration of an Opus bitstream in a track with the timescale fields of both
+ the Movie Header Box and the Media Header Box set to 48000, we would use the following edit:
+ segment_duration = the number of the valid samples
+ media_time = the number of the priming samples
+ media_rate = 1 << 16
+
+ The Edit List Box is applied to whole movie including all movie fragments. Therefore, it is impossible to tell
+ the actual duration in the case producing movie fragments on the fly such as live-streaming. In such cases,
+ the duration of the last Opus sample may be helpful by setting zero to the segment_duration field since the
+ value 0 represents implicit duration equal to the sum of the duration of all samples.
+<a name="4.5"></a>
+ 4.5 Channel Layout (informative)
+ By the application of alternate_group in the Track Header Box, whole audio channels in all active tracks from
+ non-alternate group and/or different alternate group from each other are composited into the presentation. If
+ an Opus sample consists of multiple Opus bitstreams, it can be splitted into individual Opus bitstreams and
+ reconstructed into new Opus samples as long as every Opus bitstream has the same total duration in each Opus
+ sample. This nature can be utilized to encapsulate a single Opus bitstream in each track without breaking the
+ original channel layout.
+
+ As an example, let's say there is a following track:
+ OutputChannelCount = 6;
+ StreamCount = 4;
+ CoupledCount = 2;
+ ChannelMapping = {0, 4, 1, 2, 3, 5}; // front left, front center, front right, rear left, rear right, LFE
+ Here, to couple front left to front right channels into the first stream, and couple rear left to rear right
+ channels into the second stream, reordering is needed since coupled streams must precede any non-coupled stream.
+ You extract the four Opus bitstreams from this track and you encapsulate two of the four into a track and the
+ others into another track. The former track is as follows.
+ OutputChannelCount = 6;
+ StreamCount = 2;
+ CoupledCount = 2;
+ ChannelMapping = {0, 255, 1, 2, 3, 255}; // front left, front center, front right, rear left, rear right, LFE
+ And the latter track is as follows.
+ OutputChannelCount = 6;
+ StreamCount = 2;
+ CoupledCount = 0;
+ ChannelMapping = {255, 0, 255, 255, 255, 1}; // front left, front center, front right, rear left, rear right, LFE
+ In addition, the value of the alternate_group field in the both tracks is set to 0. As the result, the player
+ may play as if channels with 255 are not present, and play the presentation constructed from the both tracks
+ in the same channel layout as the one of the original track. Keep in mind that the way of the composition, i.e.
+ the mixing for playback, is not defined here, and maybe different results could occur except for the channel
+ layout of the original, depending on an implementation or the definition of a derived file format.
+
+ Note that some derived file formats may specify the restriction to ignore alternate grouping. In the context of
+ such file formats, this application is not available. This unavailability does not mean incompatibilities among
+ file formats unless the restriction to the value of the alternate_group field is specified and brings about
+ any conflict among their definitions.

-## ------ ##
-## Usage. ##
-## ------ ##
-
-# This file is a library for parsing options in your shell scripts along
-# with assorted other useful supporting features that you can make use
-# of too.
-#
-# For the simplest scripts you might need only:
-#
-# #!/bin/sh
-# . relative/path/to/funclib.sh
-# . relative/path/to/options-parser
-# scriptversion=1.0
-# func_options ${1+"$@"}
-# eval set dummy "$func_options_result"; shift
-# ...rest of your script...
-#
-# In order for the '--version' option to work, you will need to have a
-# suitably formatted comment like the one at the top of this file
-# starting with '# Written by ' and ending with '# warranty; '.
-#
-# For '-h' and '--help' to work, you will also need a one line
-# description of your script's purpose in a comment directly above the
-# '# Written by ' line, like the one at the top of this file.
-#
-# The default options also support '--debug', which will turn on shell
-# execution tracing (see the comment above debug_cmd below for another
-# use), and '--verbose' and the func_verbose function to allow your script
-# to display verbose messages only when your user has specified
-# '--verbose'.
-#
-# After sourcing this file, you can plug processing for additional
-# options by amending the variables from the 'Configuration' section
-# below, and following the instructions in the 'Option parsing'
-# section further down.
-
-## -------------- ##
-## Configuration. ##
-## -------------- ##
-
-# You should override these variables in your script after sourcing this
-# file so that they reflect the customisations you have added to the
-# option parser.
-
-# The usage line for option parsing errors and the start of '-h' and
-# '--help' output messages. You can embed shell variables for delayed
-# expansion at the time the message is displayed, but you will need to
-# quote other shell meta-characters carefully to prevent them being
-# expanded when the contents are evaled.
-usage='$progpath [OPTION]...'
-

-# override it after sourcing this library to reflect the full set of
-# options your script accepts.

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
