pyAudioAnalysis Library

pyAudioAnalysis Library is a python library for audio feature extraction, classification, segmentation.

Specifically, pyAudioAnalysis covers multiple audio analysis tasks including

1. Extract audio features and representation
   • mfccs
   • spectrograms
   • chroagram
   • etc.
2. Classify unknown sounds
3. Train, tune parameter and evaluate classifiers
4. Detect audio events and exclude silence periods from long recordings
5. Perform supervised segmentation (joint segmentation-classification)
6. Perform unsupervised segmentation (e.g. speaker diarization)
7. Extract audio thumbnails
8. Train and use audio regression models (e.g. emotion recognition)
9. Use dimensionality reduction to visualize audio data and content similarity.
