To round out my noise maker posts, here is a really old project of mine. SineSweeper was the very first project I wrote to the CoreAudio API for Mac OS X. I started it in 2004, and added some more waveforms, and turned a bug in the original into a knob! This one makes the best bloopie noises I’ve ever heard. I’ve gotten stuck for hours playing with this thing.
To Do: add a record button, add some bit-crush and down-sampling knobs for even more videogame-y fun.
