Rd: [PD] spectrogram in PD

[alberto.zin at poste.it]

Hi Andrea,

welcome! Simple spectrum computations can be found on the 
documentation annexed with pd: look at
the subfolder /doc/3.audio.examples of your PD distribution
, for example E01.spectrum.pd. This uses simple fft 
computations.

Then there is the cyclone library that has a good 
spectrum visualization example in the patch 
spectrum-pm.pd for example. Note that cyclone only comes 
with "extended" distributions by H.C. Steiner or
you have to install it yourself. If you have the 
extended one the patch is in the 
\doc\examples\cyclone\
subfolder.

Another interesting example is here:

http://crca.ucsd.edu/~jsarlo/pd/

grab the "pitchnoise" patch, it contains another interesting
example. 

Hope that it helps,

Alberto Zin

PS: by chance I got two books by you on my desk:
your thesis on musical notation and the books on "Audio &
Multimedia". Congratulations, nice works!
