aubio

wavesurfer plugin

I have been playing a bit with the tcl plugins of wavesurfer: here you see the label track with the onsets placed where they have been detected by aubioonset. It needs some more features but it seems to work out ok. The funniest option is the Split sound on labels one. It produces one file for each segment, so it's easy to make a Hydrogen patch with them for instance.

Update: The aubiocut command line now does the slicing automatically.

audacity plugin

i finally managed to get those 10 lines of lisp working, but i had to patch the audacity package a bit. here is a screenshot of what it should be:

This is a simple screenshot to show aubio running with jack. Right now it simply plays a woodblock sample at each detected onsets.

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 <a href="http://batook.org/sons.php"

title="samba batucada/La Batook/Grenoble/France">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
