Following D3108 / 876f6d5e50, sounds are attenuated by their actual
distance. However, as noted by players on A24, the dropoff is stark and,
when zoomed out, can easily result in not hearing things that are
happening in the middle of the screen.
The new default settings almost double the max-range, change the minimum
range to have greater dynamic range, and reduce the stereo depth
slightly to better match the default camera FOV.
These are stored per sound-grounp, possibly allowing future tweaks on a
per-soundgroup basis, and are configurable.
