After subscribing to /r/glitch_art, I wanted to see what I could do by corrupting an image on purpose.
I opened the image in GIMP and saved it as an uncompressed TIFF file so that I would have the raw bytes of the image. Then I opened it as U-Law-encoded raw data in Audacity.
As long as I didn’t edit the headers (the ends of which were indicated by a small quiet blip) or change the length of the audio, GIMP had no difficulty opening the new file, exported as uncompressed U-Law-encoded raw audio and renamed from
- Bass/Treble adjustment
- Fade In/Out
- Noise reduction
