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