APPARATUS AND METHOD FOR MULTICHANNEL PARAMETRIC CONVERSION Russian patent published in 2011 - IPC H04S3/00 G10L19/14 

FIELD: information technology.

SUBSTANCE: converter generates parameters which determine the relationship between a first and a second channel for a multichannel audio signal, associated with configuration of a multichannel acoustic system. Level parameters are generated based on object parameters from a plurality of audio objects associated with a downmixing channel, which are generated using audio signals of an object associated with audio objects. Object parameters contain an energy parameter which indicates energy of the audio signal of the object. A parametric generator is used to obtain coherence and level parameters which combine the energy parameter and reproduction parameters of the object, and which depend on the desired reproduction configuration.

EFFECT: less complex application of various systems which are designed to encode and decode parametric multichannel audio streams.
