Dolby Atmos is an advanced audio technology developed by Dolby Laboratories. It provides an immersive and three-dimensional sound experience that goes beyond traditional surround sound setups. Instead of using traditional channel-based audio, Dolby Atmos employs object-based audio, where individual sounds are treated as objects that can be moved freely in a three-dimensional space.

With Dolby Atmos, sound designers and engineers have the ability to precisely place and move sounds around the listener, including overhead, to create a more realistic and enveloping audio experience. This makes movies, TV shows, video games, and music feel more immersive and lifelike.

The setup for Dolby Atmos typically includes speakers placed around the listening area, including speakers on the ceiling or speakers with upward-firing capabilities to create overhead sound effects. Additionally, Dolby Atmos can also be experienced through compatible headphones, soundbars, and other audio devices.

Dolby Atmos is commonly used in modern movie theaters, allowing filmmakers to create more engaging and dynamic soundscapes for audiences. It has also become popular in home theater setups, where dedicated AV receivers and speaker configurations can recreate the Dolby Atmos experience in a domestic environment.

As of my last update in September 2021, Dolby Atmos was widely supported across various streaming platforms, Blu-ray discs, and video games, with a growing library of content available in this format. However, please note that there may have been further developments and advancements in Dolby Atmos technology beyond that date. For the latest information, I recommend checking the official Dolby website or other reputable sources.
