A Python library for audio feature extraction, classification, segmentation and applications


""Features""

  • Extract audio features and representations (e.g. mfccs, spectrogram, chromagram)
  • Classify unknown sounds
  • Train, parameter tune and evaluate classifiers of audio segments
  • Detect audio events and exclude silence periods from long recordings
  • Perform supervised segmentation (joint segmentation - classification)
  • Perform unsupervised segmentation (e.g. speaker diarization)
  • Extract audio thumbnails
  • Train and use audio regression models (example application: emotion recognition)
  • Apply dimensionality reduction to visualize audio data and content similarities
