Live TV streaming equivalents like YouTube TV, Sling TV, and Hulu + Live TV, still lack Dolby Atmos support but this could change in the near future. Comcast used its X1 platform to deliver the 2020 Tokyo Games (broadcast in 2021) in both Dolby Vision and Dolby Atmos - a special event, to be sure, but also a sign of things to come. Unfortunately, Dolby Atmos has yet to make its way into all traditional TV platforms, but the evolution is under way. Some, like Netflix, charge a premium price for this surround-on-steroids sound, but others, like Disney+, Apple TV+, and Amazon Prime Video, include it in their standard tiers.
For years, this was the exclusive domain of 4K UHD Blu-ray discs, but in 2021, nearly every major on-demand streaming media service offered titles in Dolby Atmos. One of the keys to getting Dolby Atmos at home is having access to movies or TV shows that have been produced with Dolby Atmos soundtracks. Thanks to Dolby Atmos-compatible A/V receivers, soundbars, and even speakers built into TVs, there are now plenty of versions of Dolby Atmos for the home, with prices starting at just $150. Taken together, these qualities make Dolby Atmos a far more immersive sound experience than traditional stereo or even previous surround sound formats. The classic example is the sound of a helicopter that can start deep in the front of your TV room, then rise up, fly overhead, and gradually disappear behind you - all while the movie’s score continues to play from all of your speakers at once. Second, Dolby Atmos lets audio engineers treat sounds as objects that can be moved around freely in 3D space, independently of any other sounds. Standard 5.1, 7.1, or even 9.1 surround sound systems only place their speakers around you, not above you. First, it uses “height channels” - usually in the form of ceiling speakers or up-firing speakers - that let sounds appear to be coming from above you. What is Dolby Atmos? For a deep dive into the technology, I recommend you take a stroll through our no-stones-left-unturned Dolby Atmos explainer, but here’s the short version: It’s an advanced form of surround sound with two distinct characteristics.

From movie theater to home theater Dolby Labs Not familiar with Dolby Atmos? Here’s a guided tour to the ways it shaped 2021, and will continue to evolve in the years to come. What started out as a seismic shift in the sound systems used in commercial movie theaters is now sending reverberations through every aspect of home and mobile entertainment, from streaming services to soundbars, and even the tunes you listen to during your daily commute. In 2021, those trends all took a back seat to the earthquake that is Dolby Atmos. Over the years, we’ve seen our fair share of trends in the audio industry, like hi-res audio, active noise cancellation, and whole-home multiroom wireless speakers.
