OK well i've used fiddle~, bonk~ and an altered version of the example 'sinedecomposer' (that comes with pd) to successfully extract, and re-synthesise, the pitches and relevant amps of a source.
now i need pd to tell me when 'noise' occurs, and possibly re-synthesise it too, although this is not strictly neccesary in the first instance.
for example, a sample of guitar feedback and snare rolling - - - i can extract the pitches amps and durations of the held tones, and also the transients (amps and durations/timing) of (most of) the snare. however, my machine (obviously) interprets the pitch of the snare as clustered pitches - which as we all know it really is - however it's not cpu-feasible to make a bank of enough oscillators to reproduce whitenoise!
basically, i need pd to tell me the amplitude of a sound that is more noise than tone - like wind, snares, etc.
i thought about zero crossings, and i found an object called zerocrossing~ BUT do not know how to import it into my mac's pd and get it working.
sorry for the long message, any ideas?
or even better--- any patches? -

yoyoyo can anyone compile this for mac os x?

lol i should've just called you up innit
ta muchly
about to try these ideas -
safe indeed!!!!!!!!itsalunken~

ok! sorry, lemme try again:
i want pd to tell me the amplitude (down to zero=none) of any white/pink/brown/any type of NOISE there may be in a source, instead of/as well as multi amps of multi PITCH.
i know fully well that noise itself is just extremely multi and clustered pitch... but this does not help when trying to extract-
ie, snare sounds in a band recording (not just sudden transients, because they can be instrumental/not percussive) OR wind in an outdoor recording of a choir (or something).
...i've got the pitch bit sorted, using various implementations of fft.
i hope that makes more sense...
