A sound system that creates immersive, three-dimensional audio for everyone in a room has been developed by one of the creators of the MP3 audio format.

It uses a principle known as “wave field synthesis” to create complex audio illusions for everyone within a defined space. Computers are used to predict the way multiple sound waves will interact with each other within a space. Then, a multitude of small speakers — as many as 400 positioned around a large space — are used to mimic this interaction.

The technology can create the impression that a sound is being generated directly in front of one member of the audience. It can also be used to make a sound appear to move around an auditorium.
