Audio processing in Python with Feature Extraction for machine learning
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¶
