)
the final pitch estimate for the current frame
spectrogram bin width, Hz
frequency per bin of spectrogram
minimum height of spectral peak, dB
maximum tolerated deviation of peak frequency from multiples of f0, proportion of f0
if TRUE, produces a plot of spectral peaks
Estimates how far harmonics reach in the spectrum by checking how many spectral peaks we can find close to multiples of f0.
