FIELD: calculating; counting.
SUBSTANCE: invention relates to computing for processing a digital audio signal. In the method, the technical result is achieved by performing a research in a valid signal segment available at decoding of at least one period in the signal, which is determined as a function of said valid signal, analysis of the signal in said period for determining spectral components of the signal in said period, synthesis of at least a substitute weft of the lost frame by construction of a synthetic signal from: an addition of selected components of said determined spectral components, and a noise added in the addition of component, wherein the amount of noise added by the addition of components is weighted based on voicing information of the valid signal, obtained by decoding.
EFFECT: technical result is to improve the quality of the audio signal after correction of frame loss.
