8 Dolby Atmos Facts: How to Work to Profits

Dolby Atmos is – Did Sinaumed’s know about Dolby Atmos? When it comes to Dolby Atmos, almost everyone who is sensitive is probably familiar with it. This is because, in general, we often go to our favorite cinema to watch the film that we are most looking forward to, and the logo and words “Dolby Atmos” often appear on the theater screen there.

Dolby Atmos refers to one of the special technologies that can create immersive and surprising sound. As for this sound, it always lingers around us so that in the eyes of ordinary people, the sound effects that are present because of this technology are referred to as 3-dimensional (3D) sound.

Dolby Atmos facts

So, what facts do we need to know about Dolby Atmos and its uses? Let’s watch this article to the end to find out more!

1. Surround Sound becomes 3D

Dolby Atmos is a more advanced technology than its predecessors, such as 5.1 and 7.1, when it comes to including speakers around the room to create a complete 3D sound experience. Introduced in 2012, Dolby Atmos includes placement of up to 64 speakers in front of, around, and above you. This is what adds dimension and direction to specific sounds for specific areas with high accuracy.

The main thing to note with Atmos is the concept of audio objects. In earlier technology, sound was sent to a specific channel, aka the portion of the audio that was routed to a specific speaker. With Dolby Atmos, sound designers don’t have to limit sound to specific channels.

They can determine where an individual sound is coming from and where it is moving, and the Atmos system will interpret that data and play it back in virtual 3D space.
As a result, the sound that is felt is as if it is coming from the room where we are sitting. For example, the sound of raindrops falling or the sound of a helicopter as if flying above us.

With Dolby Atmos, the base level of sound is still mixed using the traditional channel-based approach, including ambient static sound that doesn’t require any specific precise placement. Audio objects are placed on top along with their respective spatial metadata to create a more dynamic experience. This technology allows up to 128 audio channels and 10 of them are used for the base layer, leaving 118 for audio objects.

While it may sound overwhelming and overwhelming like shoving multiple speakers down our throats, overhead sound isn’t a bad idea for movie theaters. Unfortunately, this is a pretty tricky idea to work with in a home theater. Even so, the Dolby Atmos system has potential in theaters. Traditionally, in movie theaters, one horizontal plane currently produces all the sound. It extends both in front of, and behind, the listener.

That is, for any audio: helicopters hovering overhead or rockets fired from behind, other surround sound formats simulate the effect by phase shifting speakers.

Having more speakers up top would help, but there’s nothing better than having actual speakers to handle that sound. As movies progress into more 3D aspects, filmmakers may be a little more enthusiastic about experimenting with the same expansive 3D audio.

Dolby Atmos seems to offer that option. Because, Dolby’s way of designing Atmos allows for the use of an ever-expanding array of speakers.

2. How Dolby Atmos Works with Object Approaches

Dolby Atmos is Dolby’s newest surround-sound technology, which now extends the traditional 5.1 and 7.1 formats. Dolby Atmos differs by focusing not only on the X and Y axes, but also on the vertical Z plane of sound reflection.

Its role in channel encoding is not to do audio mixing for certain settings. Instead, Dolby Atmos takes an object-based approach, mixing right before the sound leaves our speakers. Dolby itself describes Atmos as “the most significant development in cinema audio since surround-sound .”

Atmos introduces a new height variable to the traditional surround sound model and changes the way Dolby encodes audio channels. Primarily, Atmos is designed for theaters and high-end home installations, allowing for additional height variable via in-ceiling speakers. This also increases the maximum number of speakers in the system to 64 speakers.

In a home theater , Dolby itself recommends only adding two or four reflective or ceiling-mounted speakers to an existing 5.1 or 7.1 setup, but Sinaumed’s can use up to 34 speakers when associated with Dolby Atmos.

Back in the theater role, Dolby Atmos allows up to 128 audio tracks and objects, complete with spatial metadata, internal mix on powerful hardware to match specific theater speaker setups, thus ensuring highly accurate sound placement. In other words, the format is speaker agnostic .

The last piece of the Dolby Atmos puzzle is content compatibility. The format requires specifically compatible content, so it’s far from the default mode. Fortunately, hundreds of blockbusters have been produced with the Atmos audio system since 2012 abroad and 2013 in Indonesia. The format is supported on Blu-ray, and streaming services like HBO Max and Netflix also offer some titles with Atmos audio.

On the other hand, of course, smartphones don’t have access to multiple speaker placements. Sinaumed’s is lucky if the Sinaumed’s cell phone has two front-facing speakers. In contrast, Dolby Atmos for smartphones is a software-based solution that works when playing content through headphones. This mobile version aims to emulate the 3D audio effect that we get with a typical circular sound system.

3. Have Various Advantages

Sinaumed’s, there are four main advantages of Dolby Atmos sound effects:

Makes interesting sound effects in the cinema

Sound using the Dolby Atmos system comes from all directions, including overhead, creating an incredibly clear, full, detailed and immersive sound effect in theaters.

Making voices linger around us

The sound effects of the film playing on the screen will linger around us in three-dimensional space, making us feel as if we are inside the plot.

Provides a surprising mobile entertainment experience

When used on mobile devices, the sound effects stimulate the senses and make the heart flutter, bringing you various shocking entertainment experiences.

Conveys the creative intention of the artist

Dolby Atmos delivers incredible new features for artists to tell stories, dub, or play music to fully convey a work.

4. Hear Sound with Dolby Atmos Through Sound Shots

Another fact that we need to know and of course it really makes us curious is how to listen to sound with this one system. In fact, the easiest way to hear about it is to watch a movie in a theater with the technology.

Another option is to use a home theater and increase the audio settings. Of course, when it comes to upgrading this personal system, 64 speakers is a huge challenge or maybe downright crazy. That’s why Dolby and other home theater brands have introduced products to expand Atmos’ reach.

Soundbars will be increasingly able to play Atmos movie soundtracks by incorporating speakers that “shoot” sound up into the ceiling or by virtually reproducing the Atmos effect through digital processing.

If Sinaumed’s has room for a surround speaker setup, it’s the best way to enjoy immersive object-based audio with the ability to add speaker modules to an existing setup. To get the Dolby Atmos effect from a speaker package setup, we also need an AV receiver to decode the Atmos sound. There are many options available, such as the Denon AVC-X4700H.

So even if we can’t recreate a full 64-speaker cinema setup at home, we can still get a good Dolby Atmos experience, at least in the living room.
That said, before we worry about the speakers, there’s some other information to be aware of. First, we don’t need a new Blu-ray player. A standard Blu-ray is capable of carrying the necessary Atmos data just like an Ultra HD Blu-ray, unless Sinaumed’s wants to upgrade to a UHD Blu-ray there are no format issues to worry about.

In terms of use with enhancements, all headphones are also capable of playing Dolby Atmos as no special technology is required to make them work.

5. Dolby Atmos vs. Dolby Digital or THX

Dolby Atmos is very different from Dolby Digital or THX audio delivery methods. First, the system supports up to 128 simultaneous, lossless audio streams . These can function as individual channels (as in the 7.1 soundtrack ).

Atmos also serves as a voice for the individual sound elements placed in the mix. The system also allows up to 64 separate speaker feeds . Yes, 64, Sinaumed’s.
However, not many theaters or content creators are redundant enough to take advantage of all those speakers yet.

Dolby Atmos also provides something that no other circuitry sound system has: discrete point source sound reproduction. Two main things could come out of this. First, we can have an overhead sound effect (something that is very difficult to simulate using the older surround sound technology). Second, we can also hear sound coming from separate sources at certain theater locations!

6. Dolby Atmos in Home Theatre

For use at home, Dolby Atmos still relies on audio objects and requires an audio-visual receiver (AVR) which also has capabilities such as Dolby Atmos. This receiver will automatically know how many speakers are in use, their type, and position.

The object audio renderer (OAR) from there will unload any metadata to scale each audio object appropriately and output it over the specified speakers. All this tracking is done instantly, Sinaumed’s.

What’s both interesting and cool about using Dolby Atmos at home, of course, is its versatility. This is because Dolby Atmos can be played on almost any speaker configuration, even on 34 speakers.

After all, the more speakers we have, the more precisely positioned each audio object will be. You can also upgrade the system if you don’t have the space or money to buy a 34 speaker setup. Of course, this setup is actually quite over the top to do at home.

When designing speakers that support Dolby Atmos, Dolby relies on psychoacoustics which are deliberately designed to recreate the “sound of air” even if only positioned a few meters up.

The speakers reflect sound waves from the ceiling and redirect them back to the listener. While this doesn’t mean we can’t use in-ceiling speakers, we recommend using at least four speakers: two in front and two in back for an optimal listening experience.

What’s more, if Sinaumed’s already has a good speaker setup that doesn’t support Dolby Atmos. We can invest in a custom speaker module that includes a trigger upward element. By placing this over traditional speakers, our home theater now supports Atmos.

7. Dolby Atmos on Smartphones

Basically, Dolby Atmos can also be used on smartphone speakers. That is, this technology becomes software that mixes and filters multi-channel audio for stereo headphones only. However, even then, there will be a 3D sound experience using binaural audio techniques.

We can experience Dolby Atmos sound through our smartphones , tablets or headphones because this system is designed to adapt to any device. However, don’t expect overhead or ambient sound when listening to it via a smartphone .

Atmos can be used on mobile phones by combining traditional virtual surround sound technology with object-based audio from Dolby Atmos. The combination of the two allows the headphones to reproduce a convincing version of a 3D soundscape.

Quoting Trusted Review, Dolby says that manufacturers can embed Atmos into both software and hardware, meaning Sinaumed’s doesn’t need special hardware to use it though Apple’s Spatial audio with Dolby Atmos uses the accelerometer on select iOS devices. That effect is just what is needed on the device.

Dolby Atmos isn’t universally supported yet, but that future is not far off. In fact, if we buy a new flagship phone from companies like Apple, Motorola, Oppo or Samsung, we can be guaranteed to practically taste it.

As previously mentioned, this phone also has a higher price than mid-range phones. Two notable gaps are the Google Pixel 6 and 6 Pro.

Dolby Atmos isn’t the only high-end audio technology from Dolby that we can find on smartphones. There are also a number of devices boasting the Digital Plus format which are based on a similar psychoacoustic perception model for spatial audio.

8. Dolby Atmos and VR Technology

Soundguys said that the surround sound from Dolby Atmos would be a perfect fit and could enhance the experience of using VR technology. So, for VR games and cinema to be effective, the audio must also be immersive.

In 2016, Dolby Atmos was used in the VR film “ Perspective Chapter 2: The Misdemeanor ”. It’s filmed from a first-person perspective, so accurate audio reproduction is essential to keeping viewers engaged. Dolby’s Ceri Thomas stated, ” We’re enabling viewers to empathize with the characters, to hear their voices in a unique way .”

While it may not be the coolest technology out there, Dolby Atmos technology is definitely seeping into the world of entertainment. Whether Sinaumed’s is watching a movie at his favorite spot or staying home to stream his favorite movie, there are many ways to enjoy Atmos audio.

With the upcoming release of the Sennheiser Ambeo soundbar and similar sound systems, we’ll likely continue to hear about Dolby Atmos and its evolution. Especially as VR content has become more accessible these days.


Dolby Atmos is how to achieve the position of the sound object. For example, if a bullet flies, the sound of the bullet will be heard one by one from the speaker, so that the positioning is stronger and more realistic. As it fell from a great height, the wind next to it sounded from the bottom up. When the glass shattered, sounds came from all directions.

Usually, the sound of rain, thunder, flying helicopters, we can only feel from the front or behind. By using Dolby Atmos, we will feel these sounds coming from above because there are indeed many speakers above our heads.
