instruments, in particular, recording and playing acoustic signals. SUBSTANCE: method for processing of input signal involves its Hilbert transform, preliminary multiplication by absolute value of Hilbert signal transform, and dividing by Hilbert signal transform. This operation after scaling produces output signal. Device has phase shifter, multiplier, analog signal divider, units calculating absolute value and sign functions, and scaling amplifier. EFFECT: improved quality for transmission of wide-band acoustic signals through narrow-band channels. 2 cl, 1 dwg
