6 years ago So far the algorithms implemented in #145 are quite unreliable, there's just no combination of the options that would perform good enough on most data. We need a better algorithm.
Possibly a DFT could help here, since for most songs, the beats / measures are pretty visible in the spectrum view. Postponing into another issue.
Add an algorithm that would detect BPM and MPM for each song. If the song has a genre assigned, use that genre to fine-tune.
