Hello,

I'm looking for tricks or abstractions for finding the tempo of polyphonic musical sentences.

I'm planning to use several instances of [bonk~] with settings that matches patterns from at least eight differents spectrum bandwidthes, following some algorithms described in this paper:

http://igitur-archive.library.uu.nl/math/2006-0727-200320/Typke_04_search-me...

But before writing some code I'd like to know if such project has been already done.

I've used long ago an external that is able to find out a tempo following a musical sentence, I'd be glad to look at sourcefiles, for reproducing this work with pd internals, but don't remember the name.
