Abstract:We propose an objective measurement method for pitch extractors' responses to frequency-modulated signals. It enables us to evaluate different pitch extractors with unified criteria. The method uses extended time-stretched pulses combined by binary orthogonal sequences. It provides simultaneous measurement results consisting of the linear and the non-linear timeinvariant responses and random and time-varying responses. We tested representative pitch extractors using fundamental frequencies spanning 80 Hz to 40… Show more
