I figured a game development forum would probably be the best place to ask this, although the issue isn't actually involved with a game.

Thanks to my new Arduino I was able to successfully read the digital tach wire in my brothers S2000(a Honda sports car). To put it simply, I am able to get a tachometer rating pumped into the computer at a nice fast rate. My issue is that I want to use this tach information to replicate the sound of a car, preferably in real time. My issue is I'm a horrible programmer as it is, and I don't know the first thing about sounds.

I want to be able to take the tach reading and somehow use it to modify sounds. Which includes, but is not limited to things like using my own voice as the RPM reving noise, replacing the engine sound with that of a bigger engine(sadly there is actually a market for that), and perhaps taking any looping sound effect and using it.

"Why?" you ask. Well, basically because I think it could be interesting. But the problem is I really don't know where to start here. I have the tach data updating every 1/20th of a second(give or take if my math is right). I've created a basic visual display for this, and it functions quite nicely, but messing with audio is a bit more difficult. I believe most any programming language that supports Serial data interactions should do the job.

Anyone have any ideas, or good starting points for me?
