Onset Detection in Audacity 2.0.3 (running on OS X 10.5.8)


is there anyway to have onset detection for speech in audacity? I have a single file, with many different words recorded and I’d like to get the timestamps for the onset of each one of these words.
I did a little search, and I found a plugin (http://aubio.piem.org/)… but I can’t make it work. Any suggestion?

thank you very much for the attention

Have a look at Silence Finder http://manual.audacityteam.org/o/man/silence_finder_and_sound_finder.html#silence and Sound Finder http://manual.audacityteam.org/o/man/silence_finder_and_sound_finder.html#sound
The position of a label can be found by clicking in the label, and then reading the “Selection Start Time” from the Selection Toolbar http://manual.audacityteam.org/o/man/selection_toolbar.html

For a rough and ready way, just zoom in on the start of the word http://manual.audacityteam.org/o/man/zooming.html and read off the time from the Timeline above the audio track http://manual.audacityteam.org/o/man/timeline.html

Aubio should work if you installed it as a VAMP plug-in though it may not necessarily give a better result than Silence or Sound Finder.


Dear Gale,

following your suggestion, it works nicely and it seems to capture onsets pretty well. Thank you very much
