Engine Sound Algorithm

Engine Sound Algorithm
Hi all.

First of all sorry for my bad English.

You have a nice game and very detailed. Congratulations.

I'm developing a Open Hardware / Open Source sonud and lights module for rc trucks and machines based on Arduino.

There are commercial modules but they are expensive and not very flexible. I also searched for similar projects but only find sound generators based on square waves for rc boats.

I'm working on the engine sound for my project, but I don't know where to start.
I need that the engine sound changes depending the position of throttle stick, like in real engines.

This afternoon I thought that I can use the algorithm that car games use to generate engine sound and find this game searching an Open Source car game.

I had in mind use engine sound at various rpm and mix them somehow, but looking at your cars I've discovered that you generate the engine sound from a Wav file that only has a piece of audio with the engine at maximum rpm. Would be great and very helpful for me I someone coud explain me how It's done.

I've looked intro source code of developement version but didn't find the concrete algorithm.

The module is for my track loader excavator, but I want that it can be used also in trucks and other types, just changing engine sound files. If you like, you can see It on my personal blog (

Thans a lot for your help.
