Spectroscope~

I have been following a recent thread about capturing a spectrum analysis as
a graphic image. Spectroscope~ makes the sort of image I need but provides
no way to save the image as a jpg or video frame. I already have a patch
that interprets the columns of a jitter frame as a spectrum and plays it via
ioscbank~. (It's available on my max download page.)

I have been generating sonogram analyses with MetaSynth and saving them as
pict files but I would like to do the whole process inside Max.

My algorithm would be...
Load a (mono) sound into a buffer~
Determine the length of the sound with info~
Scale a jit.matrix to match the buffer
Generate sonogram into that jit.matrix

I did search the archive for this but nothing applicable comes up. Any
suggestions?
