[Attenuation][Air Absorption] - When the listener moves across the min-distance transition point, the HPF pops

A pop can be heard when crossing the Air Absorption distance range while using an HPF.

From Slack: "I tracked it down to specifically the HPF – it's when the filter turns on, it jumps instantly to 20 hz, which is the clamped frequency, which is clearly wrong for HPF."
