[PD] Audio segmentation

[Jamie Bullock]

Hi,

Has anyone done any audio segmentation work in PD, along the lines of
what is provided by BBCut for SuperCollider? 

The sort of thing I am looking for is the ability to take a monophonic
input (e.g. a flute), and perform on-the-fly segmentation of the audio
into a 'database' of notes or phrases depending on pre-determined rules.
The segmented 'events' would then be available for recall in an
arbitrary order.

I have a few ideas of how to implement this PD, but I don't want to
reinvent the wheel, so if anyone has already done it and wants to
share...

Jamie
