Re: Rhythm perception
A couple of additional references in this area:
Fabien Gouyon, who is defending his PhD thesis on "Computational Rhythm
Description" very soon, available at:
http://www.iua.upf.es/~fgouyon/thesis/
and Miguel Alonso work, whose system was ranked 1st on the MIREX 2005 Audio
Tempo Extraction contest:

Further references on this area can be found at the MIREX 2004 and 2005
