What is Dolby Atmos and why do I need it?

If you’re looking for that immersive cinema experience, Dolby Atmos could be the answer…

04 Apr 2019

Dolby is a brand best known for bringing amazing audio experiences to the cinema, and for the last few years the company has been developing Dolby Atmos, which takes everything they’ve learned about delivering great sound to movie audiences and puts it in your living room.

A lot of people probably just rely on their TV’s internal speakers to pump out all the sound and for every-day watching, this is usually fine. But if you want to feel like you’re right in the middle of the action, you’ll need a dedicated sound system - and this is where Dolby Atmos brings everything together.

How does Dolby Atmos work?


How does Dolby Atmos work?

TV sound systems come in all shapes and sizes, from a single sound bar to more elaborate multi-speaker setups. And cinemas have huge (and very expensive) sound systems made up of lots of speakers all around the room, so they can put the sound exactly where it needs to be. Dolby Atmos is able to do the same sort of thing in your home, without the need to fill your room with speakers.

Home Atmos systems are able to support up to 34 speakers, but unless you’re lucky enough to have your own movie theatre, installing 34 speakers in your living room might be a bit over the top - the good news is, you can get the Dolby Atmos experience with a standard surround sound system, or even a sound bar.

Dolby Atmos sound bars work in a very clever way, they use powerful speakers in the top to bounce the sound off your ceiling and walls to simulate extra speakers and create the effect of surround sound.

If you’d like to experience Dolby Atmos in all its glory, there are around 50 cinemas across the UK that have been upgraded to support Atmos audio. You can enter your postcode at dolby.com to find your closest one.

What about DTS:X?


What about DTS:X?

If you’ve heard of Atmos, you might have come across DTS:X too.

Much like Dolby, DTS is a company that specialises in the high-quality audio most commonly found in cinemas. One of the main benefits of DTS:X is that it’s extremely flexible; it doesn’t need a particular speaker layout so you can arrange your home theatre system however you like.

In the real world, sound passes by in all directions and DTS:X replicates this by placing sound where it would naturally occur in space. But be warned, this heightened immersion does make horror movies a whole lot scarier.

So now that we know what’s what, let’s take a look at some of our best sound bars that feature Dolby Atmos and DTS:X…
