FIELD: data processing.
SUBSTANCE: invention relates to the area of audio signal processing. The technical result is achieved by calculating a first set of scale parameters, including calculating, for each band of the set of bands of the spectral representation associated with the amplitude of the indicator in the linear domain, to obtain a first set of indicators in the linear domain, and converting a first set of indicators in the linear domain to the logarithmic domain to obtain a first set of indicators in the logarithmic domain; wherein downsampling includes downsampling the first set of scale coefficients in the logarithmic domain to obtain a second set of scale coefficients in the logarithmic domain.
EFFECT: increased accuracy of audio processing with a large number of scale coefficients.
