Did a cover for the drone n bass project I've been working on. Faburden is a 15th century musical term for bass drone.
This started off black and white like this:
...and ended up like this:
Basically, I go through iterations of saving in Paint, opening in Picture Viewer, enlarging, print screen, paste into Paint, resizing, saving in Paint. I gradually distorted the size so the main bit ends up cassette box size.
Paint pixelates the image and reduces contrast, whereas Picture Viewer smooths the pixels and creates a black border, so over a large number of iterations you get non-uniform blurring (the A's started off the same), and mixing of white and black borders (creating shades of grey).
So, in the same way, sound sources are distorted creating noise that was not there initially.
