FIELD: electronics.
SUBSTANCE: method is characterized by determining normal spectrum of source signal, determining normal spectrum of signal, received in audio programs listening point, received spectrums are compared, signals formed during comparison are used to even out amplitude-frequency characteristic of sound-reproducing circuit.
EFFECT: automatic correction of amplitude-frequency distortions, introduced by real sound-reproducing circuit without using special test signal.
