this does almost the opposite of what I want, it converts audio to
colors. I need to look up the pixel values in a video image and get them
out, eventually as audio.
For the deep dive, you can see my Rutt/Etra Scan Processing emulation in
the Vector Synthesis library:
Also, the [pix_sig2pix~] object is also limited by the blocksize.
