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

Your modified versions of the FDK AAC Codec must carry prominent notices stating
