[Csnd] Good estimation of harmonics

Subject[Csnd] Good estimation of harmonics
Hey hey,
I am trying to create harmonic spectra of sampled waveforms. For the purpose 
of this partiulcar case, the waves are a few seconds long and completely 
static.

At the moment I'm using a crude mechanism working on an FFT. For samples from 
vocal tracks this worked quite well. Strangely, for this much "easier" case my 
instrument fails me.

Is there an instrument/opcode in Csound that could do it or another 
_commandline_! utility that could extract relative amplitude of harmonics?

I'd just hate to do them all by hand, with 64 amplitudes it gets rather 
tedious. :)

Best wishes and thanks,

Jeanette

Maybe you could use pvstrace?
