How to make the car's engine sound?

The racing car games like "Black Mamba Racing", "Nano Rally", their car's engine will change if you are applying force to the car. (The sound will change according to the car's speed). So how to do that in iPhone?
Thanks!!!!

Lots of ways to approach this, the most obvious is to use an engine sound in a loop and alter the pitch in OpenAL. Good for Doppler effects, too.

Does pitch means frequency?
