Dolby Atmos Explained

Dolby Atmos Explained
 Dolby Atmos

Dolby Atmos has been available in theaters since 2012, and more recently added to home theater devices including Blu-ray players, A/V receivers, and speakers. However, if you’re like most people who are new to the world of surround sound, you might not know what Dolby Atmos actually is, or why it’s so exciting. That’s where this guide comes in! We’ll cover the basics of Atmos and explain why it’s such an exciting advance in home audio technology. Let’s get started!

Dolby Atmos is the pinnacle of entertainment audio technology, bringing movies to life in your home like never before. But what exactly does that mean? How does it work? This guide will explain Dolby Atmos and give you the information you need to choose between different home theater systems that include Dolby Atmos — not just receivers, but also soundbars and speakers. In addition, we’ll take a look at how Atmos differs from other surround sound technologies such as 5.1, 7.1, and 9.1 surround sound systems, which are commonly found in home theaters today.

What is Dolby Atmos?

To start, Dolby Atmos is a home theater audio format, not a format for music. With that said, you do need some type of speaker system to playback a Dolby Atmos audio track. Depending on what kind of speakers you have and how you’ve set them up in your room, there are different ways to make use of your speakers. First, it’s worth mentioning that anyone who has seen or heard any kind of surround sound knows that it consists of five channels: left-front channel, right-front channel, center channel, left-rear channel, and right-rear channel. That’s still true with Dolby Atmos. However, instead of just having one rear channel like traditional 5.1 surround sound, Dolby Atmos has two additional height channels. These two height channels are designed to give you an immersive experience by allowing sounds from above (like footsteps) to come through your ceiling speakers as well as sounds from below (like rumbling engines) to come through your floor speakers. The end result is that you feel like sounds are coming from all around you rather than just being projected out into space in front of you. If these concepts aren't making sense yet, don't worry—it's hard to explain without actually hearing it yourself!

Phone and Dolby Atmos

Want to use your Dolby Atmos-enabled smartphone as a soundbar? You can! Dolby recently released an update that enables phones with Snapdragon 820 or 821 processors and Android 7.0 Nougat or higher to output Atmos audio from any app to your home theater system. All you need is a receiver that’s capable of decoding it, like Yamaha’s RX-A3070. This also means you could take a movie file, transfer it to your phone, then stream it back over Wi-Fi and still enjoy those immersive effects. To make all of that happen, though, you must be running a device powered by one of Qualcomm’s latest SoCs; namely, their Snapdragon 820/821 line. The former was found in 2019 flagships like Samsung’s Galaxy S7, HTC’s 10, LG’s G5, and Google's Pixel XL while the latter was used in 2020 devices such as Sony's Xperia XZ Premium. And while some 2022 devices were upgraded to support Atmos (like OnePlus' 5T), most 2021 flagships haven't yet been updated. For example, Samsung's Galaxy S9 still doesn't have it despite rumors claiming otherwise. The reason for that isn't because they don't want to but rather because there are technical limitations preventing them from doing so right now. The good news is that even if your phone lacks support for Atmos out of the box, you can still add it yourself using third-party apps. There are two popular ones: Dolby Atmos Surround Sound Upmixer and Dolby Access - both available on Google Play Store. They're essentially plugins that allow any media player to decode Atmos content without actually having access to compatible hardware.

Is it Worth it?

With Dolby Atmos soundbars starting at less than $500, there's never been a better time to upgrade your home entertainment system. The goal of Dolby was to bring a more theatrical feel to home theater and it has succeeded brilliantly with its new format. There are some sacrifices you'll have to make, including installing extra speakers around your room. But if you're a movie buff who is looking for that ultimate immersive experience, then Dolby Atmos is worth every penny.

What Do I Need to Experience?

As mentioned above, you'll need an Atmos-ready AV receiver and some high-quality overhead speakers (or upward-firing speakers). The setup costs can add up but it should be worth it if you're serious about your home theater. Dolby says more than 12 million speaker systems are already in homes around the world, but not all of them will be ready for Dolby's new virtual surround standard. So check with your manufacturer and find out what kind of support they offer before plunking down your cash.
