I wrote a new Processing sketch today (I love the inspiration that time off affords) that takes color information from each pixel in an image, and uses that to create sound. I extracted the red, blue, green, hue, saturation and brightness of each pixel, and created a sine wave for each value. Together, they create interesting harmonies, a sort of audible version of my last project.

There are two versions that I am sharing. The first is the original version, that uses Supercollider to generate the sound. Since it does so, I can’t post it on the web, but the sound is much better. You can download the package here. The second uses a Processing friendly, and web friendly, library, Minim, which doesn’t sound as good (I can’t get rid of the pops and clicks when doing sine waves for some reason), but I allows me to post the sketch on the web, which I have here. Enjoy!

Update: By the way, it sounds much better on speaker set-ups with subwoofers, as there are some really low frequencies that would come out distorted on smaller, laptop speakers.

Experiment with creating sound from visuals, through painting on the soundtrack area of filmstrip.
