Converting Moving Image to Sound and Back Again

    Mar 02 2013 | 2:30 pm
    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?
    Here's the patch:

      found this patch which i think is doing what you want:

      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)
