What is the modern cinema sound system called?

It’s an advanced surround sound technology developed by Dolby Laboratories that creates a 3D audio experience by allowing sound to move around the theater — not just from the front, sides, and back, but also overhead. This makes effects like rain, flying helicopters, or moving crowds feel incredibly immersive and lifelike.

Other modern systems also include DTS:X and Auro-3D, but Dolby Atmos is currently the most widely adopted in commercial cinemas.
