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.

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.
