See http://freecycle.redsteamrecords.com Paul Brossier's Aubio library includes command-line programs called aubioonset, aubionotes and aubiotrack that will do this in real time from live audio input via JACK, using several different methods. (Freecycle uses the Aubio library as well.) Sonic Visualiser can also do this using any extraction plugin written to the Vamp plugin API. Aubio-based Vamp plugins are available too. The Vamp SDK also includes a standalone command-line host for running plugins directly on WAV files. http://aubio.piem.org/ http://www.sonicvisualiser.org/ http://www.sonicvisualiser.org/vamp.html Chris
