FIELD: acoustics.
SUBSTANCE: invention relates to means of audio signal processing. Device has a processor with set of filters, unit for determining fundamental tone, overtone determination unit, signal processor designed for modification of selected band-pass signal of fundamental tone, based on selected model modification and capable to modify selected band-pass signal overtone connected to dedicated band-pass signal of fundamental tone, and depending on modification of selected band-pass signal. Signal processor generates signals with amplitude and frequency modulation for each band-pass signal and may correct FM signals selected band-pass signal of fundamental tone on selected model modification. Signal processor also allow any modification of FM signals of selected band-pass signal overtone associated with band-pass signal of fundamental tone. Device comprises unit of information, intended for convergence of modified band-pass signal of fundamental tone, modified band-pass signal overtone and not selected band-pass signals of multiple band-pass signals to obtain modified audio signal.
EFFECT: high sound quality.
