| 7 | The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software |
| 8 | that implements the MPEG Advanced Audio Coding ("AAC") encoding and decoding |
| 9 | scheme for digital audio. This FDK AAC Codec software is intended to be used on |
| 10 | a wide variety of Android devices. |

Fraunhofer IIS FDK | 6cfabd3 | 2018-02-26 20:17:00 +0100 | [diff] [blame] | 12 | AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient |
| 13 | general perceptual audio codecs. AAC-ELD is considered the best-performing |
| 14 | full-bandwidth communications codec by independent studies and is widely |
| 15 | deployed. AAC has been standardized by ISO and IEC as part of the MPEG |
| 16 | specifications. |

Fraunhofer IIS FDK | 6cfabd3 | 2018-02-26 20:17:00 +0100 | [diff] [blame] | 18 | Patent licenses for necessary patent claims for the FDK AAC Codec (including |
| 19 | those of Fraunhofer) may be obtained through Via Licensing |
| 20 | (www.vialicensing.com) or through the respective patent owners individually for |
| 21 | the purpose of encoding or decoding bit streams in products that are compliant |
| 22 | with the ISO/IEC MPEG audio standards. Please note that most manufacturers of |
| 23 | Android devices already license these patent claims through Via Licensing or |
| 24 | directly from the patent owners, and therefore FDK AAC Codec software may |
| 25 | already be covered under those patent licenses when it is used for those |
| 26 | licensed purposes only. |
