MULTICHANNEL AUDIO ENCODER, DECODER, METHODS, AND COMPUTER PROGRAM FOR SWITCHING BETWEEN PARAMETRIC MULTICHANNEL OPERATIONAL MODE AND MODE OF OPERATION WITH SEPARATE CHANNELS Russian patent published in 2022 - IPC G10L19/08 

Abstract RU 2785944 C1

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.
