“Chaos Response”

This chuck code is a response to Schmidhuber’s paper¹ concerning the computation of all possible universes and the ideas behind cellular automaton.

The central sound is synthesized using a particular recursive “dynamical equation” to calculate the audio samples, which facilitates the chaotic behavior of the audio².

Check it out:

“ChucKu”s

These two chuck files are “ChucKu”s³ which generate some sound. “bubbles.ck” generates an ascending field of filtered impulses that sound to me like some juicy bubbles. Modifying the 100 at line 12:38 of the file yields some interesting patterns in the impulse delays. “spiralup.ck” creates a modulated ascending square wave that sounds pretty spacey. Modifying the frequency of the sine wave at 10:52 sounds pretty crazy.
