Cool. Have you still got the code for that? Some dudes on the forum have been tring to make a beat slicer like Freecycle using that exact method.

Hello,
In 2004 I had a live improvisation patch that did something similar (it was used during a bass/keyboard/computer concert with two musicians):
- first you had to record into a 30 sec buffer (fretless electric bass at that
time); recording was trigged manually at special moments
- during the recording, attacks were detected with [bonk~] and the times at
which they occured were stored in a [table] (there was a kind of chronometer that started at the same time as the recording)
- after the recording was finished, you could play the buffer with a MIDI
keyboard; each key played the sound of the buffer from a specific time taken in the [table] mentionned above (there was also a trapeze enveloppe for avoiding clicks)
- actually, the sound was not played as recorded but by a phase vocoder similar
to the one that you can find in the pd.fft.examples, in order to timestretch the sound with a default precession speed of 10% or such (MIDI aftertouch was then used to alter the precession)
With a flute, you would have to replace the [bonk~] by a different "rule" (unless you only play tongue rams and key percussion)

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...
