Conference Paper

The MPEG-4 General Audio Coder

Authors: Grill, Bernhard

AES Conference: 17th International Conference: High-Quality Audio Coding · Paper 17-015 · September 1999

Abstract

The MPEG-4 General Audio Coder-Bernhard Grill, Fraunhofer Institut für Integrierte Schaltungen IIS-A, Erlangen, Germany (Invited): The paper presents the MPEG-4 general audio (GA) coder which, unlike the MPEG-4 speech or synthetic coding schemes, is designed to work with any type of audio material. The GA coder includes all features of MPEG-2 AAC, plus extensions for improved coding quality at very low bit rates, including the TwinVQ scheme. In addition, embedded coding techniques-where one program is represented by a hierarchical set of coding layers-further extend the capabilities.
