[Audio] - Fixed loud sfx volume, now uses an exponential volume curve that fades away quickly as you move away from the source. Also fixed an inconsistency in panning.I don't know how this exactly works, but it seems the "fade away" does not work at the slider SFX sldropen.wav and sldrclos.wav.
For example: I use custom SFX for the sliders at my new map. When passing the sliders with the car, the volume of the SFX stay the same till the end of the SFX effect is reached (2-3 seconds). So if I pass the sliders with high speed, and I am already far away from the slider, I still can hear the SFX in the same volume as it was when I was directly at the SFX source (center of the slider object).
The same issue can be also seen at the Spa-Volt 2 or Hull Breach 3000 tracks, where I also used custom slider SFX.
