[gst-devel] Audio pipeline: how to detect beats, BPM counter

I'm looking for hints about implementing a gstreamer-based BPM counter
and beat detector (from alsasrc).
The first approach i though of would be using frequency filters
(low-band filter for beats), but then how to get a numerical value of
the volume in output (and emit a corresponding gobject bus signal
when threshold is passed) ?
I'd appreciate any hints towards pre-investigated beat detection /
sound analysis tips and tricks.
