FIELD: information technology. ^ SUBSTANCE: in the audio-coder codes of key information are created for one or several audio-channels where a code of the key information bending around is created by characterising time bending around in the audio-channel. In the audio-decoder E that which is transferred by the audio-channels (audio-channel) is decoded for creation C audio-channels of reproduction, where C >E >=1. The received codes of the key information include a code of the key information bending around, corresponding characterised time bending around the audio-channel corresponding the transferred channel (channels). One or several transferred channels mix with the increase in the number of channels for creation of one or several channels mixed with the increase of the number of channels. One or several channels are synthesised for reproduction by the application of codes of key information to one or several channels mixed with the increase of the number of channels where the code of key information bending around applies to the channel mixed with the increase of the number of channels, or to the synthesised signal for the adjustment of time bending around the synthesised signal on the basis of the characterised time bending around so the adjusted time bending around in essence coincides with characterised time bending around. ^ EFFECT: widening the arsenal of resources for coding audio-channels. ^ 42 cl, 27 dwg |
