     6  1.    INTRODUCTION
     7  The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
     8  the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
     9  This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
    10  
    11  AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
    12  audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
    13  independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
    14  of the MPEG specifications.
    15  
    16  Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
    17  may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
    18  individually for the purpose of encoding or decoding bit streams in products that are compliant with
    19  the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
    20  these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
    21  software may already be covered under those patent licenses when it is used for those licensed purposes only.
    22  
    23  Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
    24  are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
    25  applications information and documentation.
