The frames of this gif (image data) were edited in audio editing software. It’s in the realm of glitch art as the effects created are largely unpredictable. It’s a matter of saving an image in an uncompressed format, importing into Audacity, applying an effect or two, and exporting back again.
I saw a link to it via a retweet by Hilary Mason
I started with a JPG of a photo rummaging around my desktop pictures, a photo of a cholla cactus I took maybe 10 years ago:
In Photoshop, I resized it to 800x600px and then exported it as a TIF image (as instructed) with these settings:
The pixel order (per channel RRGGBB) is the key thing… I am guessing.
In Audacity, you are going to actually import this TIFF via File -> Import -> Raw Data. I used these settings:
You then get an image file’s data inside an audio editor!
It’s not much to listen to:
From what I understand, you want to select everything after the first 5 seconds (which is supposedly the header data, meta data about the file), and then apply some effects. I did one effect at a time, exported, then did “undo” to try a different effect.
When you export the “audio”, make sure you use the same option for the import (I used “U-Law” and do not know what that is). Select “other uncompressed files” and hit the options button– set the headers to “RAW (headerless)” and the encoding options to “U-Law”:
The file name will be something like
cholla4260003b.raw but I changed the file extension to be “.tif” I could not open the files in Photoshop (errors on header information), but I could open them in Preview, and then save as JPG.
Here was some different variations I made in this quick foray
It’s pretty interesting to experiment with, I like the use of using software to edit a type of media it was not perhaps designed to work with. The fact you can import raw data says a lot about the approach to software by the folks that created Audacity.
