There's a technique in photography for achieving glitch effects that consists in loading a picture in Audacity as a raw archive, editing (EQ,delay,reverb, anything) the sound and then exporting back to .bmp to get a glitch image. It can also be done backwards: exporting in audacity a .wav as a .bmp (it's not that easy, but I managed to do so by extracting the header of a bmp, exporting as .raw and change it to .bmp), edit it in Paint and exporting back to wav (usually you will get a shit). This process takes a while, and I was wondering if someone that knows a little bit of programming can help me to do a converter from .wav to .bmp to make it faster. If it is an easy task, I would love to make a VST with an open-source Paint to use it as an experimental synthesis technique. I want to remark that this is not effect that is used in Iris, which edits the spectrum, it's very different. If it is useful we can submit it to KVR developers challenge as an Audiosex community plugin. I've ended my exams for now, and I have time to learn by now. This is how the glitch images are done. https://www.youtube.com/watch?v=ODVqhMenF4E. This is how color red sounds with this technique. https://mega.co.nz/#!fVoQHBTb!MlndB_gJBEnhZBpSlISYoQqxqtuZ5DWIYJREVVP8q6M. And this is a simple Haas effect utility plugin I made in Flowstone, I've incorporated dry/wet knobs and different delays for L/R so you can get different comb filters in L/R https://mega.co.nz/#!qBpCkDhb!ApGvnixx3aLz-YZV30mZOKgHgjoj91Qumcrv2U7e9ic.

 

WAV <> BMP you'll prolly need to do some FFT & iFFT along the way. You'll prolly need to decide the resolution of picture conversion and some other parameters.

http://photosounder.com/ < there's this, which is the same concept available commercially.

 

I don't think that the image in the video linked by toni is read like a spectrum to be trasformed with an iFFT but the image is read like a matrix of 1280 x 720 and the colour information of each pixel is somewhat related with the value of the sample. I'm a bit skeptical about the predictability of the result of such operations, they have a lot of appeal but not all that practical utility but hey this is my opinion

 

this is very interesting, though i have no idea how to covert wav <> bmp..but i will test the dll later tonight..

 

toni_aguirre, your plugin is good.. here are some samples i've tested with - download here

 

Ah, right, ignore my previous post, - I didn't watch the video. Now, that sounds relatively easy to do, playing with headers and interpretation. You could probably make a CLI exe, drag & drop via .bat. A VST GUI & file handling in VST would probably be the hard bit.
