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. | |
