7 1.    INTRODUCTION
8The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software
9that implements the MPEG Advanced Audio Coding ("AAC") encoding and decoding
10scheme for digital audio. This FDK AAC Codec software is intended to be used on
11a wide variety of Android devices.
12
13AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient
14general perceptual audio codecs. AAC-ELD is considered the best-performing
15full-bandwidth communications codec by independent studies and is widely
16deployed. AAC has been standardized by ISO and IEC as part of the MPEG
17specifications.
18
19Patent licenses for necessary patent claims for the FDK AAC Codec (including
20those of Fraunhofer) may be obtained through Via Licensing
21(www.vialicensing.com) or through the respective patent owners individually for
22the purpose of encoding or decoding bit streams in products that are compliant
23with the ISO/IEC MPEG audio standards. Please note that most manufacturers of
24Android devices already license these patent claims through Via Licensing or
25directly from the patent owners, and therefore FDK AAC Codec software may
26already be covered under those patent licenses when it is used for those
27licensed purposes only.
28
29Commercially-licensed AAC software libraries, including floating-point versions
30with enhanced sound quality, are also available from Fraunhofer. Users are
31encouraged to check the Fraunhofer website for additional applications
32information and documentation.
