- "This software module was originally developed by
- Fraunhofer Gesellschaft IIS / University of Erlangen (UER) in the course of
- development of the MPEG-2 NBC/MPEG-4 Audio standard ISO/IEC 13818-7,
- 14496-1,2 and 3. This software module is an implementation of a part of one or more
- MPEG-2 NBC/MPEG-4 Audio tools as specified by the MPEG-2 NBC/MPEG-4
- Audio standard. ISO/IEC gives users of the MPEG-2 NBC/MPEG-4 Audio
- standards free license to this software module or modifications thereof for use in
- hardware or software products claiming conformance to the MPEG-2 NBC/MPEG-4
- Audio standards. Those intending to use this software module in hardware or
- software products are advised that this use may infringe existing patents.
- The original developer of this software module and his/her company, the subsequent
- editors and their companies, and ISO/IEC have no liability for use of this software
- module or modifications thereof in an implementation. Copyright is not released for
- non MPEG-2 NBC/MPEG-4 Audio conforming products.The original developer
- retains full right to use the code for his/her own purpose, assign or donate the
- code to a third party and to inhibit third party from using the code for non
