DECODER AND METHOD OF MULTI-INSTANCE SPATIAL ENCODING OF AUDIO OBJECTS USING PARAMETRIC CONCEPT FOR CASES OF THE MULTICHANNEL DOWNMIXING/UPMIXING Russian patent published in 2016 - IPC G10L19/08 

FIELD: acoustics.

SUBSTANCE: invention relates to audio systems and is intended for generating output audio signal. Decoder comprises router of input channel to receive three or more channels of down-mixing and to receive auxiliary information, as well as two units of channel processing for generating of two treated channels to obtain output of audio channels. Router of feed channel is made with ability of input of each down-mixing channel in one of two units for processing channel, each of which receives one or more down-mixing channels, at that, each of two units for processing channel takes less than the total number of three or more down-mixing channels. Each unit of processing channel is configured with ability to generate one or more of the two treated channels depending on the auxiliary information and depending of the mentioned one or more down-mixing channels received by said unit of processing channel from a router input channel.

EFFECT: technical result - increasing of accuracy of reproducing an audio signal.
