FIELD: information technology.
SUBSTANCE: to improve audio signal coding, an audio signal is divided on at least a low frequency band and a high frequency band, the high frequency band is divided into at least two high frequency subband signals and parametres are created, based on at least three segments of the low frequency band signal, which best correspond to high frequency subband signals.
EFFECT: improved coding using tonality determination.
