Hello,
I am trying to understand how to calculate in real time the spectral centroid with PD.
Is there any suggestion?

I would need to do this with PD Vanilla, not with an external, as I need to run it in libpd
inside an embedded board running linux
It seems that without an external it is very complicated to accomplish this as I need to have several computations using arrays.

Is sigmund~ PD Vanilla and embedded-friendly? I think it might be because I run vanilla and it seems to be available to me. Maybe someone can comment on this.

I haven't needed to do too much spectral analysis, but when I've looked into it, it has seemed like sigmund~ might offer some short-cuts

Thanks for your reply. Sigmund would work only with pitched sounds, I am mostly searching for analysis on non-pitched sounds

@frodo.jedi I will recommend http://katjaas.nl/home/home.html every time!

the TimbreID library is pretty useful for this.
