iosono is the product name of an audio system presented by the fraunhofer institute and the iosono gmbh in 2004. it is based on wave field synthesis, a method to use secondary audio sources to recreate primary wave fields, that was developed at delft university of technology 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 sound 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.
