But! It's amazing what you can do with a bit of pitch shift. I'm using Finch for .wav playback.. cool little bit of code that makes OpenAL very easy. Much thanks to Zoul who wrote it! Finch lets you change the pitch of samples, all nice and smooth. Playing stuff back at different rates depending on what's happening makes things come alive. Looping very short samples and changing the pitch = game-controlled instrument. Awesome. Try it.
Here's what it sounds like so far: fmnsfx.mp3 .... is it weird to upload the sound of your game being played? =P
