Alpha: what it does not do yet

  • Key is one global estimate per track (Sattari AutoKey). Key changes, modal or atonal music are not reported separately.
  • BPM can land on half or double time. "Rough" means the strict estimator declined and a single 60-second pass was used, folded into 70–180 BPM.
  • Up to 10 minutes and 200 MB per file, mono or stereo, in formats your browser can decode.
  • Results live only in this tab. Export the CSV before leaving.
  • Fixture-tested, not benchmarked on a labelled music corpus yet: treat values as starting points.
