DEVICE AND METHOD OF GENERATING OUTPUT SIGNAL HAVING AT LEAST TWO OUTPUT CHANNELS Russian patent published in 2019 - IPC H04S3/00 

FIELD: physics.

SUBSTANCE: invention relates to audio signal processing and is intended to generate an output signal using a signal decomposition unit. Device comprises two output channels and one input channel, a background selection unit configured to extract one background signal with background signal fragments from said one input channel, a background change module configured to vary said one background signal to obtain a first changed background signal and two speakers. First speaker is located at the first heights in the auditory medium in relation to the listener, and the second speaker is located at the second heights in the auditory medium relative to the listener, besides, the second altitudes differ from the first heights. Device is configured to supply a first changed background signal to a second speaker, and is configured to supply a first input channel with direct and background signal fragments to a first speaker, which is a first horizontally located speaker.

EFFECT: technical result is high accuracy of audio signal recognition.
