Amplify( <origin>, <min_range>, <max_range>, <min_volume>, <max_volume>, <falloff> )
Amplifies the sound around the origin.
SoundFade( org, 5, 50, 0, 1, 1.2 );
1 : <origin> the location around which to amplify sound.
2 : <min_range> the minimum distance to begin applying falloff.
3 : <max_range> the maximum distance of amplification.
4 : <min_volume> the amount of amplification at max_range.
5 : <max_range> the amount of amplification with in min_range.
1 : <falloff> the rate at which amplification falls off (0 means no fall off).
