FIELD: physics, computation hardware.SUBSTANCE: invention relates to audio signal processing. Proposed method comprises audio signal filtration for division into two frequency bands and generation of multiple sub bands for signal of every frequency band. Note here that for signal in one frequency band multiple signals of sub bands are generated by conversion from time band to frequency band. For another frequency band, multiple signals of sub bands are generated with the help of bank of sub band filters. Proposed device comprises one processor and one memory device with computer program code. Note also that one memory device and one computer program code are configured to make at least one processor control over process implementation.EFFECT: higher accuracy of audio signals due to improved signal source SNR.31 cl, 8 dwg |
