METHOD AND APPARATUS FOR ENCODING MULTIPLE AUDIO SIGNALS AND A METHOD AND APPARATUS FOR DECODING A MIXTURE OF MULTIPLE AUDIO SIGNALS WITH IMPROVED SEPARATION Russian patent published in 2020 - IPC G10L19/08 G10L19/02 G10L21/272 G10L19/32 

FIELD: information technology.

SUBSTANCE: invention relates to means of encoding and decoding multiple audio signals. A mixture of said multiple audio signals is received or extracted from a memory device or any data source. Multiple estimated audio signals are generated which approximate said multiple audio signals based on additional information associated with said mixture of multiple audio signals. Decoding and demultiplexing additional information containing randomly sampled quantized time domain samples of each of the multiple audio signals. Said multiple estimated audio signals are generated using said quantized samples of each of the multiple audio signals.

EFFECT: technical result consists in improvement of efficiency of encoding and decoding of a mixture of audio signals with improvement of their separation.
