1Software License for The Fraunhofer FDK AAC Codec Library for Android 2 3© Copyright 1995 - 2012 Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V. 4 All rights reserved. 5 61. INTRODUCTION 7The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements 8the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio. 9This FDK AAC Codec software is intended to be used on a wide variety of Android devices. 10 11AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual 12audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by 13independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part 14of the MPEG specifications. 15 16Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer) 17may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners 18individually for the purpose of encoding or decoding bit streams in products that are compliant with 19the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license 20these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec 21software may already be covered under those patent licenses when it is used for those licensed purposes only. 22 23Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality, 24are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional 25applications information and documentation. 26 272.
