| Abstract(in English) | We have proposed the method which estimates fundamental frequency (pitch) in musical signal using inverse notch filter. In proposed method, we connect some inverse notch filters in parallel and we can estimate pitches whether the output power of the filter is over the threshold or not. The threshold which have been used in proposed method is a fixed threshold which is based on no sound section, but the fixed threshold has a problem that makes wrong decision when striking the keys of a piano. In this paper, we introduce adaptive threshold to the pitch estimator, and we can cope with when striking the keys of a piano. |
