I was just adding a cepstrogram patch to the examples package for my timbreID externs. I modified it and made a spectrogram example too. It's not real time though - you just load samples and it plots spectrograms using Pd's struct & scalar objects. If you want to take a look at it, you can download the externs and examples at my site: www.williambrent.com.
Here's a screenshot of a horrific soprano vibrato sample.

Has anyone made a nice real-time spectrogram[1] patch? The spectrogram.pd patch that comes with gridflow is pretty close to what I'm looking for, except that it doesn't display any past data, but I figured before i started figuring out how gridflow works I'd check to see if anyone had done the work before. (Or a gem-based one).
Thanks!
