Hi again guys. I was wondering how I could analyse the envelope spectrum of a signal, and find the peaks of this signal. What I am trying to do is to estimate the formants of speech by finding the peaks of the envelope spectrum in given frequency ranges, after the signal has been passed through [lop~] and [hip~], leaving only the desired frequencies to analyse. Currently, I am having to use [bp~] and [env~] to manually create these "peaks" (sort of like the fourier transform), like shown in the puredata tutorial website, but I was wondering whether I could create these partials dynamically and then get the frequency where the peak (maximum) occurs. I read a little bit about the [sigmun~] object, but I didn't quite get it and I can't really find any tutorials on it.

@whale-av Thanks man, I ended up figuring out how to use [sigmund~] for that sort of stuff with the help of a friend. Turns out there's a lot of unpacking business that I didn't know about haha
