Abstract

In this paper, we propose a method of the pitch frequency estimation using comb filters and the estimation of playing musical instruments using harmonic frequency structure (spectrum) of a musical tone. We can estimate the pitches of mixed musical instrument sounds by remarking the zero outputs of cascaded comb filters. To estimates the playing musical instruments, we evaluate a subtraction between the spectrum of the separated monophony and the single musical tone prepared for the template matching processing. We could obtain better results than the previous method which used the signal waveform separated from the mixed musical instrument sounds using comb filters.
