I just tried to generate sound for my car game http://www.brasurf.com.au/CraigsRace/
and I didn't do very well.
Problem is I don't know how to generate the sound to make the correct sound effect. I fiddled around with combining sine waves to create an engine noise, with tyre skid effects, and I did some random noise for firing rockets, however, it really doesn't sound very good.
Has anyone done anything like this before? Do most people use very short sound clips and modify them instead of generating the sound effect?
Any help would be much appreciated!
