Here is a Lotus 7/Caterham sound for GPL:
If RaceSim.net has problems, try my Freeserve mirror:
This sound orginated from Kevin Clover's Caterham Superlight update for GP3, which contained three WAV files (I don't know if Kevin made the sounds himself or they originated from GPL, but they are nicely done) one was a higher pitch, the other two the same pitch. I basically mixed them together and added a touch of bass enhancement.
The result is a superb Lotus 7/Caterham sound, which makes a nice change from the usual Lotus sounds for GPL. You also get a nice "downshift" effect as well.
I'm not sure if there are any other Caterham sounds out there, but give this one a try and see what you think.
Extract the "lot.wav" file to the "sound" directory in your GPL directory. If
you want to keep existing sound, make a backup of your "lot.wav" file first!
Note that this sound is designed with the CarSound patch in mind, so make sure
you have that installed first.
