Looks interesting . I'll take a look at it.
Thanx,

  Hi Gerald,

 I don't know the exact state of the art, but Nick Collins recently
 used "Anssi Klapuri's great 2008 paper 'Multipitch analysis of
 polyphonic music and speech signals using an auditory model'" to build
 a polyphonic pitch tracker for SuperCollider.

 Since Nicks' code is GPL, maybe you can even re-use it. See this

  Hi all,
 I'm developing a small app which uses aubio to extract the fundamental
 Frequency of a monophonic guitarsignal to drive a set of wavetable synths.
 It works quite well and I'll put up on the net when I have the time.
 But I would like to extract the fundamentals of a polyphonic signal. Does
 anyone know of a lib which does this in realtime? Or at least a state of the
 art paper I could implement?
 thanx,
 Gerald
