Ok this is a spectroscope (thanks again, this is amazing to see some much more advanced Pd mastery than mine)
But I’m looking for a spectrogram (where each pixed of a 2D graph is as dark as the loudness of that position (usually time in the x axis and freq in the y axis).
The search continues :)

I have a vanilla spectroscope abstraction: g_spectroscope. It's pretty simple and good enough for showing a graph, not really for scientific precision. There are also update & dimension controls plus you can turn it off to save CPU.

Sorry again for my obsessions with pd-vanilla which makes everything harder - this one might be impossible!
I?m trying to draw a spectrogram in pd-vanilla to match our waveform visualisation options in FluCoMa for Max and SuperCollider. I saw the example with the peaks in the documentation, and did myself a sort of grid of objects (arrays) but the former is not precise enough and the latter was clogging the machine as you might imagine?
As I am not the best Pd coder, although getting less worse by the day thanks to you all, I just want to confirm that it is definitely no possible in any other way than doing the structure of arrays of rectangles.
Any pointer welcome (pun intended again)
