A beat detection algorithm written in python.
Documentation is available in the doc folder with an explanation of the algorithm.
import librosa
import lib.beat as beat
# Load the song from a mp3 file
y, sr = librosa.load('song.mp3')
# Detects the beat in the sub and low frequencies
beats = beat.detect_combi_beats(y, sr)A More complex is also available here. This example syncs the beats with the audio and plays the song.
