There is good visual stuff in the Glitch art thread. I would like to try datamoshing by messing with WAV audio files and maybe other formats first with a text/hex editor and then standard Unix tools like sed(1), and play them primarily on norns.
Any experiences or pointers? WAV files are pretty straightforward so I wonder can serious glitching occur? How corrupt files will Softcut and SuperCollider tolerate? Has datamoshing audio files yielded something interesting for you or others?
I remember being curious but not particularly brave about editing compression codecs… like opening the MP3 codec used by VLC in a text editor and messing with variables, moving things around, and attempting to encode audio with that.
Also, I believe that the particular effect of datamoshing has to do with manipulating hidden frames that are interleaved within the video file that reference relative change. I wonder if there’s a way to do this but with the compression methods in say, MP3, which exploits psychoacoustics. I’ve always been curious to hear what would happen if you turned the MP3 algorithm to 11…
