Onset Detector

Simple onset detector. Detects onsets by finding peaks in high frequency content, and filtering found peaks using hill climbing.

Example usage

import scipy.io.wavfile
import onsetdetection
sr, audio = scipy.io.wavfile.read('audio.wav')
audio = audio[:,0] # make it mono
onsets = onsetdetection.detect_onsets(audio)

Returns a numpy array of offsets, in samples.
