Pitch detection of musical instrument sounds for transcription using cascaded adaptive comb filters

摘要

We have presented a pitch detection method of musical instrument sounds for transcription using the cascaded twelve comb filters by the elimination of the pitch and its harmonic frequencies. But this method is not suitable in the case where the played tones involve some noises and have some frequency deviations from the nominal frequencies. To overcome these problems, we propose a new method for the pitch detection using adaptive comb filters by controlling the delay number.
