- did some tweaks to the sound.

The angle was wrong and the rolloff type apparently as well. It sounds a lot better now, especially after also altering the minimum distance for the rolloff. This one is interesting, it looks like a bug where the desired value was shifted two bits too much, quadrupling the distance where volume reduction starts.
