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.
