I just posted the article[1] that I think prompted this script to be brought up.

What I did instead was to run images through an audio editing tool, which lets you apply echoes or do mindboggling things like change the volume of the image. The script can be found on github[2].

Nice script :) I did a similar thing by hand with graphicsmagick and sox a couple years ago - the most fun result was from wahwah, pretty much a wide bandpass filter with centre frequency varying cyclically over time: http://lewisinthelandofmachines.tumblr.com/post/59405537096/...

Thank you!

I haven't even tried the wahwah effect, you've definitely piqued my interest.

I had a look through the SoX effects list[1] for the wahwah, but can't seem to find it. The closest thing I found was the 'flanger' effect[2].

Shamefully I can't remember which wahwah I used - I was treating the audio with both Audacity and Pro Tools as well as sox though...

No description of each image. Which one did you change the volume?

None, but I did here[1]. Also, on a related note all image names include the effect that was used.

Nice thanks. Seems like it mostly reduces the number of colors?

Also like how clearly you can see the overdrive introducing noise into the previously pure blue sky at the top

It's more like increasing the contrast, which has the effect of reducing the dynamic range in favor of extreme values.
