Converting Moving Image to Sound and Back Again

geckohooks

Hi there, I've used max for a while but am pretty rusty so potentially this may be a stupid question! (Please forgive me if that's the case)!

I've been trying to convert a jitter signal into an audio signal and then back again using jit.catch and jit.release. These only seem to work for one line of a matrix at a time, so I also used jit.scanwrap to unfold a 2D matrix into a very long, 1D matrix before converting to sound; and then back from a 1D to 2D matrix after conversion back from sound. It produces some nice glitchy material, but doesn't look anything like the original video!

Does anyone have any suggestions?

Thanks for this d.w. Sorry for the delay in getting back - took me a while to get my head around the patch you sent! In the mean-time, I have a solution of a kind: I can turn an image into sound, and back again; but weirdly, only within the patch. When I try to record the sound, play back the recorded soundfile and convert that, it doesn't work! Here's the patch (sorry it's a bit messy, but it gets some great glitchy results)
