Dolby Atmos is a fantastic way to listen to music or watch movies, but not every Atmos sound system is created equally. What I mean by that is depending on your hardware, you might be getting an inferior experience compared to somebody else. That could easily lead somebody to believe that Dolby Atmos isn’t worth the trouble, but that’s far from the case. I went through the trouble of building a Dolby Atmos sound system in my living room, and while there’s still work to be done with it, I’m happy with what I’ve come up with.
It’s very easy to fall into the trap of thinking something like a Dolby Atmos soundbar is the be-all, end-all of the format, and I don’t blame you. Companies do a lot of marketing to make you think this way, but if you ask me, you need proper height-mounted speakers to get the real Dolby Atmos sound. Dolby Atmos is all about directional audio, and while upfiring speakers can mimic that, nothing beats the real thing. If you already have overhead speakers and still think your setup is lacking, there are a few other things you could try.
Dolby sound engineering
Trivia challenge
From noise reduction to immersive audio — how well do you really know the science behind Dolby sound?
HistoryTechnologyFormatsCinemaInnovation
In what year did Ray Dolby found Dolby Laboratories?
Correct! Ray Dolby founded Dolby Laboratories in 1965 in London, England. The company initially focused on professional recording studio equipment before expanding into consumer and cinema audio.
Not quite. Dolby Laboratories was founded in 1965 by Ray Dolby in London. He had previously worked at Ampex and developed his noise reduction ideas while studying at Cambridge University.
What was the primary purpose of the original Dolby A noise reduction system introduced in 1965?
Correct! Dolby A was designed to reduce the audible tape hiss that plagued professional studio recordings. It worked by encoding audio during recording and decoding it on playback, effectively masking the noise floor of magnetic tape.
Not quite. Dolby A was a noise reduction system aimed squarely at reducing tape hiss in professional studio environments. It used a compander approach — compressing audio on the way in and expanding it on the way out — to suppress background noise.
Which 1975 film was the first to be released with a Dolby-encoded stereo optical soundtrack?
Correct! Lisztomania (1975), directed by Ken Russell, was the first film released with a Dolby-encoded stereo optical soundtrack. This marked a major turning point in bringing high-quality stereo audio to cinema audiences.
Not quite. The first film with a Dolby-encoded stereo optical soundtrack was actually Lisztomania in 1975. While Star Wars (1977) and A Star Is Born (1976) were landmark Dolby films, Lisztomania holds the historical first.
Dolby Digital is also known by which technical designation used in industry documentation?
Correct! Dolby Digital is technically designated AC-3, which stands for Audio Codec 3. It was developed in the early 1990s and became the standard audio format for DVD video, digital broadcast, and cinema releases.
Not quite. Dolby Digital’s technical designation is AC-3. The AC stands for Audio Codec, and it was the third generation of Dolby’s perceptual audio coding technology, succeeding AC-1 and AC-2.
What audio object-based feature distinguishes Dolby Atmos from earlier surround sound formats like Dolby 7.1?
Correct! Dolby Atmos uses audio objects — individual sounds with positional metadata — rather than fixed channel assignments. This allows a renderer to place sounds anywhere in three-dimensional space and adapt the mix to any speaker configuration, from a home soundbar to a 64-speaker cinema.
Not quite. The key innovation in Dolby Atmos is object-based audio. Instead of assigning sounds to fixed channels, each sound element carries metadata describing its position, allowing the system to dynamically render it for whatever speaker layout is available.
Dolby Vision is a proprietary HDR format that competes directly with which open HDR standard commonly found on televisions and streaming services?
Correct! Dolby Vision competes most directly with HDR10 and its dynamic metadata extension HDR10+. While HDR10 is an open, royalty-free standard, Dolby Vision requires licensing and supports dynamic metadata for scene-by-scene brightness optimisation, often delivering superior results.
Not quite. Dolby Vision’s main competitors are HDR10 and HDR10+. HDR10 is the baseline open standard, while HDR10+ adds dynamic metadata — a feature Dolby Vision pioneered. Dolby Vision supports up to 12-bit color depth and 10,000 nits peak brightness in its specification.
What does Dolby MAT stand for, and what is its primary function in modern audio delivery?
Correct! Dolby MAT (Metadata-enhanced Audio Transport) is a lossless bitstream container that carries Dolby TrueHD audio along with Dolby Atmos object metadata over HDMI connections. It is what allows modern AV receivers and soundbars to receive full lossless Atmos signals from Blu-ray players and streaming devices.
Not quite. Dolby MAT stands for Metadata-enhanced Audio Transport. It is a lossless container format that wraps Dolby TrueHD audio and Dolby Atmos object metadata, enabling high-fidelity Atmos delivery over HDMI. Without MAT, devices can only receive a lossy Dolby Digital Plus version of an Atmos stream.
Which legendary rock concert film from 1978 is widely celebrated as a showcase for Dolby Stereo’s capabilities in cinema?
Correct! The Last Waltz (1978), Martin Scorsese’s documentary about The Band’s farewell concert, is frequently cited as a landmark demonstration of Dolby Stereo in cinemas. The film’s rich multi-track recording benefited enormously from the format’s improved dynamic range and channel separation.
Not quite. The Last Waltz (1978) is the celebrated Dolby Stereo showcase. Directed by Martin Scorsese, the film captured The Band’s final concert with exceptional audio quality that highlighted what Dolby Stereo could achieve over conventional mono and optical formats of the era.

Calibrate your sound system
Don’t ever skip this step
Room correction software comes with any receiver worth its salt, and it’s something you need to use. For my Denon receiver, this is called Audyssey. The way it works is that I use the bundled microphone that comes with a receiver and move it around to three different listening areas. The receiver will then send audio to each of the speakers and automatically adjust the sound depending on those positions. This software needs to be run again if you move anything in your setup due to the way it finely tunes everything to how the speakers were placed.
This is the number one piece of advice I give to anybody who’s not happy with the way their audio sounds, Dolby Atmos or not. Room calibration is a huge deal, and there’s a reason your receiver walks you through the steps of doing so when you finish setting it up. This could be all the different to a sound system that sounds bad and one that sounds good. If you’re ever running into issues, pull out that microphone and get to calibrating. Sometimes it’s not possible if you bought a used receiver, but if you bought one new, don’t skip this crucial step.
Get your soundbar in the right spot soundbar
Sometimes it is the soundbar
The simple solution is often the best solution. As I said before, Dolby Atmos and soundbars don’t mix as much as they should. The high-end ones with specific surround speakers fare much better, such as one I saw at IFA 2026, but that’s not the case for all of them. The ones that rely exclusively on upfiring speakers don’t do overhead audio as well as they should, and it’s even worse when there’s little to no separation between the speakers. All of this creates a muddy sound, but you can minimize these problems. In the case of upfiring speakers, you want a ceiling height between 7.5 and 14 feet. On top of that, Dolby recommends your ceiling be made out of an acoustically reflective material such as drywall or hardwood. That’s not always possible, especially if you’re a renter, however.
If you do this and still have some problems, then you might be faced with a difficult decision. Either it’s moving on from your soundbar to a surround sound system, which is a costly option, or buying one with more separation. In many cases, this is fixed by getting a speaker that has a set of surround speakers that you have control over. I would still consider getting an actual surround sound system, but that’s not always possible for people limited in space. If a soundbar is your only option, then you should do some extra research and find one that’s worth the price instead of looking for the most affordable one.
Change the way you’re listening
Switch from digital to physical
Something that you might not realize is that Dolby Atmos on streaming sounds different than it does physically. This is especially clear in movies. The problem with streaming Dolby Atmos is that it’s often lossy and compressed — a bad combination for your listening experience. On the other hand, a 4K Blu-ray has uncompressed audio, and if you use your TV’s eARC port, you get the most bandwidth possible.
It might not seem like it, but this is actually a pretty big difference, and it’s one of the main draws of physical media. I wouldn’t say it’s worth going out and grabbing a 4K disc for the audio upgrade alone, especially if you don’t have a 4K TV, but I’d say it’s still something that’s a nice cherry on top. Some regular Blu-ray discs have an Atmos soundtrack, but it’s not nearly as prevalent as it is on 4K. The nice part about this is that you might not have to change anything about your setup at all, it just comes down to what you’re listening to with it.
