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.

You may not charge copyright license fees for anyone to use, copy or distribute

|
the FDK AAC Codec software or your modifications thereto.
|
|
|
|
Your modified versions of the FDK AAC Codec must carry prominent notices stating
|
|
that you changed the software and the date of any change. For modified versions
|
|
of the FDK AAC Codec, the term "Fraunhofer FDK AAC Codec Library for Android"
|
|
must be replaced by the term "Third-Party Modified Version of the Fraunhofer FDK

AAC Codec Library for Android."

NO EXPRESS OR IMPLIED LICENSES TO ANY PATENT CLAIMS, including without
|
|
limitation the patents of Fraunhofer, ARE GRANTED BY THIS SOFTWARE LICENSE.
|
|
Fraunhofer provides no warranty of patent non-infringement with respect to this
|
|
software.
|
|
|
|
You may use this FDK AAC Codec software or modifications thereto only for
|
|
purposes that are authorized by appropriate patent licenses.
