hey everyone.
i've been dropping in & asking a couple of questions during the last weeks, & i'd just wanted to let you all know what this was all about.
http://www.dekonstruktiv.org/archives/95-Kunst-Als-Strafe-Sound-Reactive-Visuals.html
last weekend i was playing the wroclaw industrial festival with my band Kunst Als Strafe, & i hacked together a processing sketch to handle sound reactive visuals matching the general glitchy & fragmented minimal aesthetics.
here's what i did: i got a stereo signal & fed each channel into a 3-band beat detector. (for the sake of convenience, let's call the bands kick, snare & hihat). the screen basically consisted of two rows of 6 rectangles each, each beat detector band would trigger one rectangle in the top row, & one in the bottom row. the kick trigger on the left channel randomized the order of the top row of rectangels, the right kick trigger would randomize the order of the lower row.
additionally, a kick trigger on any of the channels would take a snap of the screen & transform it into a jpg. the resulting binary data would then be interpreted as a black&white bitmap & DARKEST-blended onto the screen.
a video of the gig showed up on youtube demonstrating what the whole thing looked like. unfortunately the sound is completely bonkers and not representative of what we really sound like. it would seem the camera wasn't able to pick up all the deep drone-y sounds.
if you wanna take a look at the sketch, you might need to adjust the frame.setLocation() call in draw() i used to move the output to the projector to your screen setup.
