Draw waveforms and hear them
Posted on: 2007-04-11 19:18:09
A while back I thought it would be interesting to be able to draw arbitrary waveforms and then listen to how they sound. I had an audio engine just laying around, so I whipped up a quick application to do that.


download WaveStudio.exe

Results

In theory, you can make any sound that you want. The results aren't very interesting. You can draw a sine wave and it sounds muffled. Add some jagged edges and the sound starts to sound more raw and high pitched. But it's okay to demonstrate what a sawtooth vs. sine vs. square wave sound like.

Future work

It would be a better to be able to draw in the time vs. frequency domain, using standard brush painting tools. Thay way you could come up with more interesting waveforms.

Which audio engine did you use?

If you could turn that into an iPad app, with frequency controls, volume controls and a few basic effects like reverb/flange that would kick ass!
