Python library librosa is a python package for music and audio analysis. It provides the building blocks necessary to create music information retrieval systems.

librosa uses soundfile and audioread to load audio files. Note that soundfile does not currently support MP3, which will cause librosa to fall back on the audioread library.

Library Highlights:

- CoreIO and DSP

- Feature Extraction

- Onset Detection

- Beat and Tempo

- Spectrogram decomposition

- Temporal segmentation

- Sequential modeling

- Viterbi decoding¶
