[Csnd] partials, crackle and pop!

Subject[Csnd] partials, crackle and pop!
I'm getting some pops when using partials that I would rather like to
avoid. I don't know if it is avoidable but I'm sure one of the pvs-ers
will be able to best advise me. Here is my instrument, I'm not sure of
how partials is supposed to be used but I quite like the effect I'm
getting from it, if only I could control the clicks. I'm balancing it
against an oscil in the instrument below in order to emphasise the
problem. Any suggestions?


instr 1
a1 oscil 10000, 440, 1
asigL, asigR soundin
"C:/MyDocuments/Documents/csoundfiles/5dotcello/piano.wav", 3;
asig = asigL+asigR
fs1,fsi2 pvsifd asig,2048,512,1 ; ifd analysis
fst  partials fs1,fsi2,1,100,100,500  ; partial tracking
apart  tradsyn fst, 0.2, .5, 500, 1 ; resynthesis (up a 5th)
abal balance apart, a1
out abal
endin

I haven't used partials a lot, but I think I remember that it uses
quite a lot of CPU resources.
Are you running in realtime ?

Reduce your analysis threshold in partials (it's too high),
try starting with around 0.003.

Thanks Victor, that's helped a lot. I'll mess with the analysis
threshold till I get the sound I want.

Rory.
