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

[Florent THIERY]

Hi,

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.

Thanks

Florent
