FIELD: physics.
SUBSTANCE: device for multichannel signal processing includes comparator between the first and the second of the two channels. Additionally, a filter of spectral ratio prediction is provided to perform filtration of prediction only with one prediction filter for both channels in case of high similarity between the first and the second channel and filtration of prediction with two separate prediction filters in case of distinction between the first and the second channel.
EFFECT: increased efficiency of coding with technology of stereosignal coding.
