Pitch detection using a spectral implementation of the YIN algorithm
- This algorithm was derived from the YIN algorithm (see pitchyin.c). In this
- implementation, a Fourier transform is used to compute a tapered square
- difference function, which allows spectral weighting. Because the difference
- function is tapered, the selection of the period is simplified.
