The inspiration for this script came from working on a 3d project where I needed to generate a seemingly natural landscape... I did some research and found a relatively simple way to do it. Midpoint displacement, or "plasma" terrain generation is explained here.

This implementation is much simpler, in that there are only two dimensions being worked with. So the audio file looks similar to a cut-away through a mountian.

EXAMPLE: RAW TEXTURE
The script was run using an empty audio file, and initially was rendered into a 5 minute buffer. I chopped the audio down to conserve bandwidth, so you're only hear a chunk of the overall data. This is what the full wave looks like:




Here is a magnification of one area:

EXAMPLE OVERLAY:
This one I ran on top of one of the holographic kick drum samples. I had to normalize it down to -20db to get it to render without clipping, so there is a bit of visual interpretation that you'll have to do to follow what is happening. This is the source (normalized to 0)

Here is the processed file. Notice the area at the end where the algoythm stops. This was the amplitude of the source signal before the script was run on it.
