METHODS AND DEVICES FOR CODING AND DECODING OBJECT-ORIENTED AUDIO SIGNALS Russian patent published in 2012 - IPC G10L19/00 

FIELD: information technologies.

SUBSTANCE: method for audio signal decoding includes extracting from audio signal the signal of lowering mixing and object-oriented additional information; generation of modified lowering mixing signal based on lowering mixing signal and extracted information, which is retrieved from object-oriented additional information; generation of channel-oriented additional information based on object-oriented additional information and control data for lowering mixing signal reproduction; and generation of multichannel audio signal based on modified lowering mixing signal and channel-oriented additional information. Object-oriented additional information contains at least one of information on object level differences, information on cross correlation between objects, information on lowering mixing amplification, information on differences of lowering mixing channels levels and information on absolute energy of objects.

EFFECT: providing more realistic reproduction of object audio signals.
