hellocatfoodback on my project of creating images from data. I think I've finally cracked how to create nice repeating patterns 🙂
Here's another one. It's so interesting how the same process can look different depending on the file type
I was going to finish this project in time for @alpaca last year but didn't. I promise to exhibit this soon! I need to work out how this looks on bigger file sizes, and maybe even mixing in existing images.
Looks like some lossy file types don't have very obvious repeating patterns. This is the qoi file format (literally means Quite OK Image). I think I need to make these images have larger resolution so the data doesn't fill up so quickly.
I'll also one day document my process but not right now.
jxr is still one of my favourite image file formats to work with. I still need to read the file spec and work out what a "vanilla" image header looks like.
As suggested by @oin I imported the jxr image into audacity (U-Law, default endianness). The image is only 256x256 but it's overstuffed with data (i.e. past its actual resolution) so the file size is around 300kb and means I can have much longer audio.
Enjoy(?)
nnenov@hellocatfood @oin sounds super cool, kinda like FM synths, i wonder if thats in any way related to jpg sinewave malarkey
3oin@nnenov @hellocatfood Yeh this is really interesting, thanks
Eric Jennings */3import image into audacity? whoa, this changes everything
yes very much enjoy thank you
@hellocatfood woa, I hadn't heard of it, looks super fun to corrupt : O
@nnenov tbh I don't know what the file format is actually used for, I just like messing with it ha! imagemagick can generate it, but not gimp
@hellocatfood Love to hear what that sounds like in audacity.
@oin sounds kinda interesting. I'll share a clip once I've generated enough data
Andy Incarnate (He / Him)@hellocatfood These are very similar to the visuals I get when I'm having a visual migraine. In the colours and disruptive pattern at least - they don't usually cover my entire field of view like that though.
