FIELD: computer technology.
SUBSTANCE: present invention relates to the field of computer technology for processing audio data. A frequency response R of a filter for linear prediction of frequency range is calculated, R value is smoothed to obtain Rsmoothed value, wherein a smoothing method is selected from a group of smoothing methods, including at least two smoothing methods, depending on a set of parameters containing multiple parameters, including the value of the spectrum steepness, slope, wherein the set of smoothing methods contains exponential smoothing with a time-fixed coefficient.
EFFECT: technical result is an increase in the accuracy of determining the optimized scale coefficient for application to the excitation signal or to the filter.
