Hi.
I just wondered how i could use sound signals to distort/make glitches in a photo.
I have tried sig2pix, but i can't manage to send the signals through a chosen picture.
Thanks

Hi.

I have been playing with sig2pix for the past week, but hadn't thought of mixing in images before. I got some good results tonight after seeing your post. It's definitely distorted.

You need one gemhead for pix_image and one for pix_sig2pix~. Pix_texture comes after you combine the two images.

Some good ways to combine are diff, chroma_key, composite, multiply, and add.

The images have to be the same size to work. I like to use pix_crop because you can scroll around a large image while retaining the correct dimensions.

I also like to add in pix_pix2sig~ before the pix_texture. You output each channel to a send~ or a delay, then you can add that back in with your R,G,B,A oscillators. This way you can have one color effect another, or possibly create feedback.

I find that the feedback gets quickly distorted. I don't know how to emulate my friend's analog RGB synth where he gets insane feedback fractals. To calculate 768x576 pixels at 30 fps you would need a sample rate of 13 million hertz. D'oh.

I know it's been a while since this post, but do you have the patch that you created in the end?

Yes I would like to see it too\
