- 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.
- 2. COPYRIGHT LICENSE
- Redistribution and use in source and binary forms, with or without modification, are permitted without
- payment of copyright license fees provided that you satisfy the following conditions:
- You must retain the complete text of this software license in redistributions of the FDK AAC Codec or
- your modifications thereto in source code form.
- You must retain the complete text of this software license in the documentation and/or other materials
- provided with redistributions of the FDK AAC Codec or your modifications thereto in binary form.
- You must make available free of charge copies of the complete source code of the FDK AAC Codec and your
- modifications thereto to recipients of copies in binary form.
- The name of Fraunhofer may not be used to endorse or promote products derived from this library without
- prior written permission.
- 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."
- 3. NO PATENT LICENSE
- 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.
- 4. DISCLAIMER
- This FDK AAC Codec software is provided by Fraunhofer on behalf of the copyright holders and contributors

- liability, or tort (including negligence), arising in any way out of the use of this software, even if
- advised of the possibility of such damage.
