[PD] Identifying the position of notes in an (audio) array

[Urs Liska]

Hello list,

I'm feeling a little bit odd with my question because it may look kind 
of like I'm tool lazy to try for myself.
But I will have a free (= patching) day tomorrow at my studio where I 
don't have internet and email access; so I would like to have some ideas 
that presumably will work before I go there.

I have to find the exact positions of audio events in an array.
Or more concrete: I will record sounds - a number of single, discrete 
sounds produced on (or in) a piano - into an array. I need a way to 
analyze this array to store the positions of the individual attacks to 
play them back in arbitrary order afterwards.

BTW: what is the best solution to measure the time between two bangs in 
samples (i.e. the number of samples recorded into an array (when the 
recording is started and stopped manually))?

I would be thankful for any helping ideas.

Best
Urs
