What I have been wanting to see is a nice time vs. frequency/amplitude spectrogram... like something that is very easy to do in matlab with the specgram function. The [sonogram~] object in the unauthorized library comes close, but it is difficult to know what is happening according to the picture.

I was trying to understand if there's a(n easy) way to plot a spectrum. I guess it should be easily feasible, as I saw both pd capabilties in time domain, both Miller Puckette's figures in the book.
But looking in docs and on the web I got confused and I'm not able to find answers to my question.
There are several examples using a spectrum display inside the Pd docs. For a quick start I would recommend 3.audio.examples/E09.FM.spectrum.pd
Inside of [pd fft] you will see the basic approach which is squaring the output of [rfft~], adding it and taking the square root.
