FIELD: processing of audio signals.
SUBSTANCE: technical result is achieved by changing all spectral coefficients of the prototype frame, included in interval Mk around sinusoid k by phase shift in proportion to sinusoidal frequency fk and time difference between lost audio frame and prototype frame, thereby including temporal unfolding of sinusoidal components of prototype frame into temporary instance of lost audio frame, and storing parameters of said spectral coefficients.
EFFECT: technical result consists in reduction of transmission errors, which can lead to situation, in which one or several transferred frames are absent in receiver for recovery.
