- ECMA-407 is the world's first approved international 3D audio standard for the unrestricted delivery of channel-based, object-based and scene-based signals up to developed by Ecma TC32-TG22 in close cooperation with France Télévisions, Radio France, École Polytechnique Fédérale de Lausanne and McGill University in Montreal. ECMA-407 uses in the time domain, an invention by the Swiss-Austrian mathematician Clemens Par, and shows lowest spatial bitrates ever achieved (for instance, several minutes of NHK 22.2 may be represented by an encapsulated data package of 100 bytes). It was chosen for the World Intellectual Property Organization Award in 2009. Inverse coding goes back to Victor Ambartsumian's scientific legacy on inverse problems and represents the first solution of its kind in audio by separating sound sources at the same frequency by a time-level model.
