1. I wonder how the continuous wavelet transform would compare to the windowed Fourier transform used here. See [1] an python implementation, for example.
2. The size of frequency analysis blocks seems arbitrary. I wonder if there is a "natural" block size based on a song's tempo, say 1 bar. This would of course require a priori tempo knowledge or a run-time estimate.

- Despoisj 10y agoThe slice size is indeed quite arbitrary, and knowing the BPM would help, but isn't reliable either (various tempos, rubato for classical etc.)
