Use the mouse to draw your own waveform! Or select some standard waves from the side. You can also change the frequency using the bar to the right, but this can be glitchy (this is a work in progress). Use this to design your own custom wave shapes, and see what effect wave shape has on sound. I made this because I had always been curious what it would sound like to be able to draw really wild waveshapes. Turns out it isnt quite as much fun as I thought, but it is interesting to play around with for awhile (until you get a headache). I also haven't had a chance to test the accuracy with an external oscilloscope. So if anyone wants to do this, please share.
