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