aubio

a library for audio labelling

There is no special interface to aubio yet. You can print results on the console, and write audio files (using libsndfile).

Audacity (the sound editor) provides a simple way of importing and exporting time labels in a text format. The onset detected by aubio can thus be imported in a separate audacity label track. This ease the selection of audio segments and tight loops in audacity.

run the example program onsetdemo on the wave file to edit (here carioca.wav):

$ aubioonset -v -i ~/carioca.wav > ~/carioca.txt

then open carioca.wav in audacity:
$ audacity carioca.wav

import carioca.txt as a label file

using aubio
onsets as labels in audacity
