Visual FX as Audio FX

Background
I wanted to use visual effects such as blurs, colour transformations and pinches as audio effects instead of visual effects.


Overview
I wrote a simple piece of software to help me out with this task. The idea is quite simple. The patch works in two phases. The first phase is to open up an audio file (of up to 8. 163 seconds in length). The patch then converts each individual audio sample into a pixel in an image of 600 by 600 pixels (this equals 360,000 samples), and saves off this image as an image file. Then, the image can be manipulated, and then reimported andconverted back to audio.


Outcomes

Here are some resulting waveforms with their corresponding images. Naturally, the images have been compressed to be uploaded onto the web so there might be some artifacts not visible in the original, uncompressed versions.
