Hi everyone,
I couldn't find a finished 3d spectrogram for GEM so I made one. Hope its useful for someone. I'm pretty new to pd and especially GEM so any comments or suggestions improvements are welcome.
Enjoy!

Could you explain it?
Also, I get a shitload of messages "matrix: row index $1 is out of range". -
Hi there. I am very interested in learning how to use your spectrogram, but i am also hoping you could provide an explanation and perhaps tell me how to use it? thanks!!

Hi,
This patch just graphs amplitudes of your sample at frequencies in time.
It works best if you open the soundfile subpatch and load your own .wav file (otherwise just use the default sample).Then click the start render toggle, use the 'scrub' slider to move through the sample, and click and drag to move around in the gem window.
The other options include the number of FFTs to display, rotation of the spectrogram on the z axis, the zooming factor, or graph input from the microphone.
I think I fixed the error messages, and I added some more comments to the patch. The patch is probably more complicated than it needs to be, but it should work more clearly now.
Let me know if there are any more problems or anything. -
Hi Russel,
Thanks so much, this patch is great and really fun to play with with live input. I know its been a while since you worked on it, but is there an easy way to access some raw numerical values too? Sometimes I'd like to see what the frequencies are for the peaks in a spectrum.
