FIELD: information technologies.
SUBSTANCE: audio signal coder comprises a facility to receive M-channel audio signal, where M>2, a facility of downmix to downmix M-channel audio signal into the first stereo signal and related parametric data, a facility of modification to modify the first stereo signal in order to generate the second stereo signal in response to related parametric data and data of spatial parameters, which specify transfer function of binaural perception, besides, the second stereo signal is a binaural signal, a facility for coding of the second stereo signal with the purpose to generate coded data and an output facility to generate out data flow, containing coded data and related parametric data.
EFFECT: increased efficiency of stereo coding of multichannel signals with reduction of coding complexity.
