AUDIO SIGNAL PROCESSING DEVICE AND METHOD Russian patent published in 2020 - IPC G10L21/208 G10L21/316 

Abstract RU 2725017 C1

FIELD: computer equipment.

SUBSTANCE: invention relates to computer engineering for processing audio signals. Technical result is achieved by performing audio signal analysis to determine a plurality of noise-cancelling filter values for a plurality of audio signal frequency bands; determining the value of the noise-cancelling filter such that the value of the noise-cancelling filter is greater than or equal to the minimum value of the noise-cancelling filter, and such that the noise suppressing filter minimum value depends on the audio signal characteristic; and filtering the audio signal based on the noise-cancelling filter values.

EFFECT: technical result is improved quality of processing audio signals.
