 ECMA-407

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 NHK 22.2 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 inverse coding 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).
