Example

1. Consider a 2D areal region used to represent a localized storm cell. If the listener is within the region, the constant sound of rainfall is to be played. If the listener is outside the region, the rainfall sound is not to be played.

   At the edge of the region, the data provider does not want the sound to just turn itself off, but to gradually fade out as the listener gets farther away. So a <Fade Range> instance is attached to the <Sound Instance> instance, defining the range at which the sound begins fading away and the range at which the sound has completely faded away.
