San Francisco - Oct 5, 2006 - Agere Systems, Coding Technologies and Fraunhofer Institute showcased their MPEG Surround audio compression technique at the Audio Engineering Society's 121st show Oct. 6 through Oct. 8.

MPEG Surround is a compression technique for multi-channel audio signals. The system provides full backward compatibility to stereo equipment and scalability in terms of the bit rate used for describing the surround sound image. Other features include a matrix surround mode for multi-channel audio based on a stereo signal, and a binaural mode for spatial rendering and reproduction of multi-channel audio on stereo playback devices.
