Two basic sin or saw generators for left and right. The sound is four LFO's running at .5, .6. .7 and .8 hertz added, subtracted and multiplied by a fixed number (1000); a pattern emerges and one side has a subtract where an add was on the left. More of concept piece, but I fine tuned the result by ea and I mastered it really-well (ie no limiter, compression). Made with ChucK (miniaudicle).
