FIELD: computer technology.
SUBSTANCE: invention relates to the field of computer technology for audio encoding of data. Switching to parametric multichannel encoding is performed in case of one source, and switching to separate encoding is performed in case of two or more sources in a determined frequency-time part, parameters of multichannel encoding of which differ for at least a set deviation.
EFFECT: provision of a possibility of reproduction of a stereo-image and provision of a voice output signal for scenarios with interfering sources of voice data.
