ENCODING AND DECODING OF AUDIO OBJECTS Russian patent published in 2012 - IPC G10L19/00 

FIELD: information technology.

SUBSTANCE: audio system has an encoder (209) which encodes audio objects in an encoding unit (403) that generates down-mix audio signals and parametric data representing the plurality of audio objects. The down-mix audio signals and parametric data are transmitted to a decoder (215) which has a decoding unit (301) which generates approximate replicas of the audio objects and a rendering unit (303) which generates an output signal from the audio objects. The decoder (215) furthermore contains a processor (501) for generating encoding modification data which are sent to the encoder (209). The encoder (209) then modifies the encoding of the audio objects, and in particular modifies the parametric data, in response to the encoding modification data.

EFFECT: improved encoding of audio objects, improved control of characteristics of separate audio objects and reduced deterioration of an audio object caused by cross-talk when controlling audio objects.
