In most cases, sounds that are farther from the listener are less important to play than sounds that are closer to it. In situations where a lot of sounds are triggered by the game, using the “Offset priority at max distance” functionality can help to clean up the mix and enhance the performance usage.
Take the following example where the audio object attenuation is set over a distance of 100 units, the priority is set to 50, and the offset priority at max distance is set to -20:

You will get the
following priority interpolation over distance for the audio
object:

Note that this graph does not exist in Wwise, it’s only to give a
visual representation of the priority over distance
decay.
