FIELD: information technology.
SUBSTANCE: method of applying reverberation to an M-channel reduced input audio signal which indicates X separate audio channels. In response to spatial label parameters, which indicate a spatial image of the reduced input signal, Y discrete signals of the reverberated channel are generated, where each of the signals of the reverberated channel at a time t is a linear combination of a subset of values of X separate audio channels at time t. The Y discrete signals of the reverberated channel are generated using a premixing matrix containing time-variable coefficients which are determined in response to spatial label parameters.
EFFECT: enabling separate determination and generation of different reverberation audio signals for each discrete channel subjected to composite audio signal upmixing.
