Another option appears to me, please correct me if i'm wrong:
extracting frequency information of the detected beats from the
plugin, putting it into the audio pipeline as a fork (tee), applying a
low pass filter based on the fore-cited frequency, and using then the
level plugin (with a threshold) as beat signal...

What do you guys think ?
