FIELD: information technologies.
SUBSTANCE: intermediate presentation of multi-channel signal channels is restored, when mixing parametres are calculated with increase of channels number for mixing with increase of number of channels of transmitted signal mixed with reduction of number of channels, into intermediate presentation of channels, which makes it possible to execute mixing with increase of channels number using the same mixing algorithms with increased number of channels, as well as during multi-channel restoration. This is achieved using facility of parametres recalculation for calculation of mixing parametres with increase of channels number, in which parametres containing information on channels that are not included in intermediate presentation of channels are also taken into account.
EFFECT: decoding of signal with high efficiency and high fidelity of reproduction.
