Iosono

Iosono is the product name of an audio system presented by the Fraunhofer Institute and the Iosono GmbH in 2004. It is partly based on Wave Field Synthesis, a method to use secondary audio sources to recreate primary wave fields, that was developed at Delft Technical University in the Netherlands in the 1980s.

Given a 3D audio "picture" of the scene, a specialised algorithm generates secondary sound waves necessary to recreate it in the particular room and then instructs a large number of speakers (300-400) to generate the "audio hologram". While traditional surround systems can only recreate the original 3D sound in a small "sweet spot", Iosono claims it can recreate the original audio in the whole room.

Wave Field Synthesis: Wave field synthesis (WFS) is a spatial audio rendering technique, characterized by creation of virtual acoustic environments. It produces "artificial" wave fronts synthesized by a large number of individually driven speakers. Such wave fronts seem to originate from a virtual starting point, the vir...
