DEVICE OF AUDIO SIGNAL PROCESSING AND METHOD OF AUDIO SIGNAL FILTERING Russian patent published in 2019 - IPC H04S1/00 H04S3/00 

FIELD: physics.

SUBSTANCE: invention relates to audio signal processing means. Filter matrix is determined based on matrix of acoustic transfer function and matrix of target acoustic transfer function. Matrix of target acoustic transfer function contains target transfer functions of target paths of propagation of acoustic signal. Target paths for propagation of the acoustic signal are determined by the target configuration of the plurality of positions of the virtual loudspeakers relative to the listener. Left channel input audio signal is filtered based on the filter matrix to obtain a first filtered left audio input signal and a second filtered left channel audio input signal. Right channel audio signal is filtered based on the filter matrix to obtain a first filtered right audio channel input signal and a second filtered right audio channel right audio signal. First filtered left audio input signal and the first filtered right audio channel audio signal are combined to obtain the left channel audio output signal.

EFFECT: technical result consists in providing surround sound without cross-talk.
