FIELD: communications.
SUBSTANCE: invention relates to gain factor correction in audio coding based on circuit sampling, and may be used for processing different types of audio signals. Method of gain factor adjustment in decoding the audio signals encoded with separate representations of gain factor and shape vector comprehends estimation of shape vector representation precision factor, determination of gain factor correction based on precision estimated figure, adjustment of gain representation based on the determined gain factor correction.
EFFECT: technical result is gain factor adjustment in decoding the audio signals encoded with separate representations of gain factor and shape vector.
