FIELD: computer technology.
SUBSTANCE: invention relates to the field of computer technology for processing audio signals. Weight values by frequency bands are assessed for two channels, weight values by frequency bands are calculated based on a target energy value for each frequency band in such a way that energy in a frequency band of a downmixed audio signal is in a set ratio to energies in the same frequency bands of the mentioned at least two channels; representation in a spectral region of two channels is weighted using weight values by frequency bands to obtain weighted representations in the spectral region.
EFFECT: reduction in delay, while providing downmix to a multichannel audio signal.
