Computing acoustic analysis locally with Essentia

After the AcousticBrainz retrieval of audio metadata completed, many tracks were tagged with a beats per minute (bpm) of zero. This is incorrect and an issue with AcousticBrainz. To correct this and other acoustic metadata, the audio files can be selectively analyzed using Essentia.

Computing acoustic analysis locally with Essentia after AcousticBrainz run:

  • Tracks in library: 31072
  • Tracks with zero bpm: 17714
  • Execute: mpplus -X bpm:0
  • Acoustic extraction: 2 days 03 hr 15 min 24 sec
