Paris, France (May 23, 2006)--Agere Systems, Coding Technologies, Fraunhofer Institute for Integrated Circuits IIS and Philips, the inventors behind the groundbreaking MPEG Surround technique, jointly demonstrated the full potential of the new surround sound system at the AES Pro Audio Expo in Paris.

Combined with an underlying audio codec such as MPEG- 1 Layer-2, MPEG-4 AAC or MPEG-4 HE-AAC (aka aacPlus), MPEG Surround fundamentally reduces bit rate requirements for high quality multi-channel audio compression and maintains backwards compatibility to existing stereo equipment at the same time.

MPEG Surround comprises a full set of tools enabling the representation, reproduction and rendering of multi-channel audio for a broad spectrum of applications, from digital broadcasting, to mobile entertainment, to Internet music distribution. In the past month, already a number of realworld demonstrations have been showcased by the developing parties, such as 5.1 surround audio for digital radio and TV via DVB-T, DAB, or HD Radio. The MPEG Surround demonstration at the AES Pro Audio Expo is the first joint presentation by all four parties, showcasing the full potential of MPEG Surround across various application fields. The new MPEG Surround standard will be frozen in July this year.

"We are excited to be jointly demonstrating the MPEG Surround technique. After mono and stereo, MPEG Surround is the next step for sound quality in today's media entertainment," commented Dr. Peter Kroon, chief multimedia architect of Agere Systems' mobility division. "It brings true surround sound to any media system at next to no overhead in transportation and storage, and preserves consumers' investment as existing home stereo equipment can stay in use. This level of flexibility will be the key for MPEG Surround to be deployed on a global scale."
