There are two main categories of Dolby Atmos that are important to differentiate.ĭolby Atmos for streaming video is available from some streaming content providers on certain titles. While Atmos height speakers can be added to practically any home theater, it’s important to know that not all Atmos content is the same. The bottom line: where standard 5.1 or 7.1 home theaters can deliver incredible sound on their own, Atmos-enabled home theaters deliver a new dimension of sound that will make you feel like you’re at the movies.

In an Atmos setup, each of the speakers is aware of their distance from the listener, and sounds from the ceiling speakers work in concert with the other speakers to deliver a customized surround sound experience based on the acoustic properties of your TV room. Height data tells the speakers where in the room sounds should take place, and not just which speaker sounds should come out of. Now, Dolby Atmos takes standard 5.1 and 7.1 soundtracks and adds “height data,” usually through two or four additional speakers that are either ceiling mounted or placed at an angle on top of other speakers. Keep in mind that a 5.1 or 7.1 setup can work with multiple audio formats, so for example, if you’re watching TV from a cable box, the sound is likely provided in 5.1 audio in Dolby Digital format, but if you’re playing a DVD, it may have 5.1 audio in DTS format.

With a standard soundtrack from a movie or TV show, sound is designed to come through specific speakers, so for example, most dialogue will be heard through the center channel speaker, while sound effects are more commonly heard in the rear or side speakers.
Sound height is a relatively new concept, so let’s dig in to what that means.Ī typical surround-sound setup has either five speakers and a subwoofer, or seven speakers and a subwoofer (which is why some surround sound is referred to as being 5.1 or 7.1). While it’s easy to mistake Dolby Atmos for a sound format like Dolby Digital or Digital Theater Sound (DTS), in reality, the term Dolby Atmos means that an existing sound format includes information about the height of sounds. Here’s everything you need to know about Dolby Atmos: what it is, what it isn’t, and how you can use it to level-up your own home theater. With this new technology, Dolby has ushered in a new era of home theater audio that adapts to any environment with what they’ve dubbed “object-based audio.”ĭolby Atmos definitely packs a sonic punch, and transforms any soundtrack into an experience, but not all Atmos is the same, so when you’re shopping, it’s important to be able to tell the difference between technical specifications and marketing jargon. Dolby’s surround sound technologies - the magic that makes movie and TV soundtracks come alive through multiple strategically placed speakers - have been around for years, but they recently developed a new audio technology that’s nothing short of a game-changer: Dolby Atmos.
