MPEG-4 Audio: Capabilities and new concepts for music distribution.

MPEG-4 Audio is the latest of the successful MPEG audio coding standards. We will discuss the capabilities of the new format. It is based on a low bit rate enhanced MPEG-2 AAC for high quality audio, and additionally offers low delay communication coder and the integration of synthetic sounds. The MPEG-4 scalaibility functionality which allows to change the bitrate of the encoded signal enables new concepts for music transmission and storage, especially for streaming over IP networks.

Bernhard Grill was born in Schwabach, Germany, in 1961. He received a M.S. (Diplom) degree in electrical engineering from Erlangen University. At the Fraunhofer Institute for Integrated Circuits (FhG-IIS) and the University of Erlangen he has contributed to the development of several perceptual audio coder systems. These include ASPEC, ISO/IEC MPEG-1/2 Audio Layer-3 (mp3), and MPEG-2 Advanced Audio Coding (AAC). Recent work concentrated on scalable audio coding, now part of MPEG-4 Audio. He was the coordinating editor of the MPEG-4 Audio standard. Bernhard Grill has been granted app. fifteen audio coding patents and has several more pending. Currently he is the head of the audio department at the IIS. He has presented numerous papers at AES conventions and other international conferences. In September 2000 he received the AES Fellowship Award for his work on MPEG-4 Audio and scalable audio coding. In October 2000, he and two collegues received the "German Future Award" of the german president for their work on MP3.
