MP3 creator returns with 3D sound

According to Karlheinz Brandenburg is credited with much of the work leading to the MP3 format. Today he and his team have created a product which offers true "three dimensional" audio. The team is targeting theaters, theme parks, and even living rooms for this audio break through.

One of the inventors of the MP3 format is back with a new technology that he hopes will revolutionize audio, creating superrealistic sound for theaters, theme parks and eventually even living rooms.

Karlheinz Brandenburg, director of the Fraunhofer Institute for Media Technology, along with a team of co-developers, is in Los Angeles this week showing off his new "Iosono" technology to representatives of Hollywood studios and giants including Disney. Brandenburg is credited with much of the work leading to the MP3 format, also developed at Fraunhofer.

He and his team are touting their new product as true "three dimensional" audio, which can give the impression of, for example, a horse galloping through the center aisle of a movie theater, or pinpoint a noise so that it sounds exactly like a person shouting from outside theater walls. The best existing surround sound speakers can approximate this only for a small "sweet spot," perhaps a few feet wide, while the Ionsono system would create the same realistic illusion for everyone in the room.
