FIELD: computer technology.
SUBSTANCE: invention relates to the field of computer technology for processing of audio data. The method includes stages, at which modulation information is received, associated with signals of an envelope for a set of frequency ranges of modulation, while modulation information describes time modulation of signals of the envelope for the set of frequency ranges of modulation and contains a set of values, which are associated with different modulation frequencies, which are present in a corresponding signal of the envelope; and received modulation information is compared with reference modulation information associated with a reference audio signal to receive information relatively to the similarity between an input audio signal and the reference audio signal.
EFFECT: reduction in computing complexity in assessment of similarity of audio signals.
