What is Dolby Atmos?

Dolby Atmos is a next-generation audio format that delivers moving and immersive audio: “sound that can be precisely placed and moved anywhere in three-dimensional space, including overhead.” The audio format premiered in June 2012 with the theatrical release of the animated film Brave.

In home theater applications, Atmos is integrated as a spatially-coded substream added to Dolby TrueHD or Dolby Digital Plus audio formats. This is different than how Atmos is used in theaters because of the limits on bandwidth and overall processing demand. Atmos is backward compatible and will revert to Dolby TrueHD 7.1, Dolby Digital Plus, or lesser formats on home theater/audio systems that don’t support it.

Other qualities of the format include:

  • Sound that is not constrained to channels and so can move all around you
  • A new overhead dimension that creates a full audio atmosphere and realistically depicts objects moving overhead
  • Everything from dialogue, quiet, and loud action scenes have clarity, richness, detail, and depth in sound quality

Dolby Atmos is featured on several Blu-ray Discs and 4k Blu-ray Discs including Terminator Genisys, Mission: Impossible Rogue Nation, Star Wars: The Force Awakens, Unbroken, and Game of Thrones Seasons to name a few (see a full list of 4k Blu-ray titles). Atmos can is also offered with digital movies from streaming providers such as Amazon Prime Video, Apple TV, Disney+, Netflix, and Vudu to name a few.
