             1.    INTRODUCTION

            
            The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software

            
            that implements the MPEG Advanced Audio Coding ("AAC") encoding and decoding

            
            scheme for digital audio. This FDK AAC Codec software is intended to be used on

            
            a wide variety of Android devices.


            AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient

            
            general perceptual audio codecs. AAC-ELD is considered the best-performing

            
            full-bandwidth communications codec by independent studies and is widely

            
            deployed. AAC has been standardized by ISO and IEC as part of the MPEG

            
            specifications.


            Patent licenses for necessary patent claims for the FDK AAC Codec (including

            
            those of Fraunhofer) may be obtained through Via Licensing

            
            (www.vialicensing.com) or through the respective patent owners individually for

            
            the purpose of encoding or decoding bit streams in products that are compliant

            
            with the ISO/IEC MPEG audio standards. Please note that most manufacturers of

            
            Android devices already license these patent claims through Via Licensing or

            
            directly from the patent owners, and therefore FDK AAC Codec software may

            
            already be covered under those patent licenses when it is used for those

            
            licensed purposes only.


            Commercially-licensed AAC software libraries, including floating-point versions

            
            with enhanced sound quality, are also available from Fraunhofer. Users are

            
            encouraged to check the Fraunhofer website for additional applications

            
            information and documentation.
