Audio Feature Extraction

Over the past few weeks, I have been working on evaluating a range of audio feature extraction tools. When I first started this project, I thought everyone uses the same features, so this should be easy – I was wrong.

I evaluated ten different feature extraction tools

  • Aubio
  • Essentia
  • jAudio
  • Librosa
  • LibXtract
  • Marsayas
  • Meyda
  • MIR Toolbox
  • Timbre Toolbox
  • YAAFE
I discovered that from this set of toolboxes, there are only three features in common to all toolboxes –
spectral centroid spectral rolloff and signal energy.
In fact, of over 250 unique features, just 30 are present in more than half of the feature extraction tools.
