Is proposed the application of the method of an improvement in the quality of the voice signal distorted by noise. Noise can be white or painted, concentrated along the spectrum in one or severalranges. Method shows good results for the cases, when rate of change in the parameters of noise is small.On the average the method gives an improvement in the relation signal noise on 20 dB.
    For the estimation of the effectiveness of the realized method the program, which makes it possible to process signals, is proposed, written down into wav format with the coding PCM. Programm processes only first 30 seconds of signal.
    Method is realized in the form of separate dll- library for the work with the Win32- applications under Win95/98/NT/2000.
