DEVICE FOR AUDIO SIGNAL PROCESSING AND METHOD FOR REDUCING AUDIO SIGNAL CROSSTALKS Russian patent published in 2019 - IPC H04S1/00 H04S3/00 

FIELD: physics.

SUBSTANCE: invention relates to audio signal processing. Input audio signal (L) of the left channel is split into the first input audio sub-signal of the left channel and the second input audio sub-signal of the left channel. Input audio signal (R) of the right channel is split into the first input audio subset of the right channel and the second input audio subset of the right channel. Moreover, the first input audio sub-signal of the left channel and the first input audio sub-signal of the right channel are allocated to the first predetermined frequency range. Second input audio sub-signal of the left channel and the second input audio sub-signal of the right channel are allocated to the second predetermined frequency range. Crosstalk between the first left channel audio input signal and the first right channel audio input signal in the first predetermined frequency range are reduced to get the first left channel audio output signal and the right channel first audio output signal.

EFFECT: technical result is to increase the filtration efficiency of the input audio signal.
