FIELD: physics.
SUBSTANCE: invention relates to encoding and decoding devices for encoding the channels of an audio system having at least four channels. Decoding device has a first stereo decoding component which subjects a first pair of input channels to a first stereo decoding, and a second stereo decoding component which subjects a second pair of input channels to a second stereo decoding. Results of the first and second stereo decoding components are crosswise coupled to a third and a fourth stereo decoding component, which each performs stereo decoding on one channel resulting from the first stereo decoding component, and one channel resulting from the second stereo decoding component.
EFFECT: technical result is high encoding efficiency of multichannel audio.
