1 Software License for The Fraunhofer FDK AAC Codec Library for Android 2 3 Copyright 1995 - 2018 Fraunhofer-Gesellschaft zur Frderung der angewandten 4 Forschung e.V. All rights reserved. 5 6 1. INTRODUCTION 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. 11 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. 17 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. 27 28 Commercially-licensed AAC software libraries, including floating-point versions 29 with enhanced sound quality, are also available from Fraunhofer. Users are 30 encouraged to check the Fraunhofer website for additional applications 31 information and documentation. 32 33 2.
