Fancy FFT Effect in Processing

Posted by Erin, the RobotGrrl on Saturday, September 20th, 2008

I created the visualization of a sound wave that I wanted to do for a while :)

I used Processing, with the minim library.

Here’s a video of it: ^_^

It’s based on the code by Tom Gerhardt :) Mine differs in the way that it “erases” (actually draws a black rectangle over the stage) some of the past blobs. This way it creates the effect of an actual live visualization of the FFT log average of the sound, rather than an average of an average. :P

Download the code here!

I’m going to try to see if I can make this my visualization of the sound wave through live input… ^_^

    Hmm, I wonder if you put an LED Matrix in a robot…you could have its belly light up with visual effects.

    Check them out at SparkFun.

    (They have less expensive versions, too. But the one above is RGB and has serial control.)

    Hi Erin, Very cool. Separate and apart, I finally saw Wall-E. Totally AWESOME.
    Thanks for the recommendation. Just love Wall-E and Eve. They make an adorable
    couple. ;-)
