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. |
