Air simulates the natural dampening that happens to higher frequencies from sounds as they travel through air, providing perfectly simulated frequency responses to dialogue or effects that you want to sound naturally distant. Air is perfect for simulating the physical behavior of sound moving through the air, turning your mix into an incredibly immersive sonic experience.
Air already includes settings from different locations around the globe, from Antarctica to Death Valley, but you are always able to enter your one custom values.
Air is much more accurate than a simple low-pass filter, using exact frequency response values of air dampening.
With Air, you can see the actual frequency response that is being applied to the sound.
Control the volume over distance with the Distance Attenuation parameter.
