Los Angeles, CA (July 26, 2004)--A new immersive sound system, IOSONO, was introduced to the Hollywood entertainment industry at an event hosted by the Entertainment Technology Center at USC at Todd-AO. Introduced by Prof. Dr. Karlheinz Brandenburg, renowned for his pioneering work on the MP3 format, IOSONO was developed by the Fraunhofer Institute for Media Technology by Brandenburg and Drs. Thomas Sporer and Sandra Brix.

"We have spent many years developing this technology to accomplish two things: to give audiences natural sound and give artists more tools with which to create the," explained Brandenburg. "It is our belief that the enhancement from 5.1 to IOSONO is comparable to the step from mono to stereo."

The IOSONO system projects sounds as if they are coming from a specific spot inside or outside the listening area. It provides a perfectly balanced "sweet spot" for every listener, wherever they are positioned in the audience.

The demonstration included a T3 video game trailer remixed in the IOSONO environment by award-winning Todd-AO mixers Stanley Johnston and Scott Gershin. Both mixers voiced their opinions that IOSONO provides a more immersive and natural-sounding experience for listeners than existing conventional multichannel methods. According to Gershin, IOSONO permits a widening of the "center" dialog channel and allows the mixer to pan more precisely to the screen image.

Designed for applications in cinemas, theme parks, music and entertainment venues, and home theaters, IOSONO applies Wave Field Synthesis and several new patented hardware and software technologies. The system comprises the Spatial Audio Workstation, used to create the IOSONO soundtrack, an IOSONO server, installed in each venue to configure an IOSONO-produced soundtrack to the specific environment, and a 360-degree ring of speakers, hung in a specially calibrated fashion.
