We propose a robust probabilistic pitch (f0) estimator in the presence of interference and low SNR conditions, without the computational requirements of optimal time-domain methods. Our analysis is driven by sinusoidal peaks extracted by a windowed STFT. Given f0 and a reference amplitude (A0), peak frequency/amplitude observations are modeled probabilistically in order to be robust to undetected harmonics, spurious peaks, skewed peak estimates, and inherent deviations from ideal or other… CONTINUE READING
