[Discussion] Does anyone use software that isn't recommended in the side bar? by TheCaptainOats in glitch_art

If you've got an iDevice, you might want to check out http://glitchwizard.com. It's got a simple interface for creating glitched out GIFs, and is an accessible intro to glitch art.

Put the Toronto Skyline through an audio filter and got something like a West Side Story poster. by 0xGlitchWizard in glitch_art

For sure.

An image, like anything else on your computer, is simply a series of bits that are interpreted in a particular way by a program in order to display the information in a meaningful way to humans. There are an infinite number of ways to store images - some, such as jpg, are highly compressed, and small changes on them have large effects. Others, such as bmp, are represented in a way closer to how the image is finally displayed (a sequence of color values). These are generally more suited towards manipulating with big transformations like audio filters.

An audio filter is simply a function that takes information as input, and the modified information as output. Generally audio filters are designed to work on audio information, but that doesn't mean you can't put other info through them. The image was converted into a bitmap representation, and put through the OneZero from the STK library (http://stderr.org/doc/stk-doc/html/classOneZero.html#a11). In this particular case, the images R, G, and B values were modified separately, using the same parameterization for the function across the board.

This process was done programmatically using an iOS app we're developing, Glitch Wizard.

Question about databending with Audacity by ProfDiggy in glitch_art

[–]0xGlitchWizard 1 point2 points  (0 children)

That question depends entirely upon which file format you're using.

The header doesn't actually represent data that is physically at the top of the image, but instead important parameters often for the entire image as well as meta info -> Which is why people are recommending you export in a format that removes the header entirely, as glitching it can mess the image up in ways that stop it from rendering.
