What is Audi A8's active suspension feature?

Can anyone explain how Audi's active suspension works in the A8 model and its benefits?

The Audi A8's active suspension system uses air springs and an electronic control unit to automatically adjust the suspension for a smoother and more comfortable ride.

In addition to enhancing ride quality, Audi's active suspension also improves handling and stability by minimizing body roll during cornering and braking.

I have found that the active suspension feature on my Audi A8 has greatly reduced road noise and vibrations, making each drive more enjoyable.
