FIELD: physics; measurement.
SUBSTANCE: invention relates to multi-channel decoding and particularly where there are at least two transmission channels. The device for generating a multi-channel output signal compensates for the centre channel so as to obtain improved main channels for restoration of left-sided output channels or right-sided output channels. The device comprises a channel compensation calculator which uses information related to the initial centre channel, which is available in the decoder, a coupler for coupling the transmission channel with the compensation channel, as well as a restorer for generating a multi-channel output signal. As a result of compensating the centre channel, the channel restorer (26) does not only use different main channels to restore the centre channel, but also uses main channels, different from transmission channels, to restore left and right sided output channels, which are under reduced or even completely neutralised effect of the initial centre channel.
EFFECT: provision for high-quality multi-channel restoration of signal, with improved sound perception.
