Home theater audio has gone a long way since sound choice has been limited to mono or stereo. Today, surround sound systems have taken over, and they come in different standards and platforms. Dolby Digital vs Dolby Atmos is two of the most widely used surround sound formats.
What is surround sound?
Mono is audio coming from one channel. Stereo is audio coming from 2 channels. The stereo sound comes to the right and left without including above, below, and behind. Surround sound, on the other hand, is a mixing process.
Surround sound includes 2 channels and may include 5 speakers and 1 subwoofer, 7 speakers and 1 subwoofer, or up to 21 speakers and 1 subwoofer. It all depends on the number of speakers you want to mix in the process.
As the term connotes, surround sound “surrounds” the listener with 3600 sounds coming from the left, right, above, and below, making the sound more realistic. It is more commonly used in home theater systems and can either be digital or analog.
When you speak of surround sound standards, Dolby Digital and Dolby Atmos always make it to the top of the list.
- Dolby Digital is the original multiple-channel audio technology. It uses specialized encoding and decoding technology to reproduce multichannel audio to deliver a cinematic sound experience in home theaters.
- Dolby Atmos follows in the footsteps of Dolby Digital to deliver a cinematic sound experience. It has become the newest standard in surround sound. This audio format debuted in movie theaters but has since been developed to support home theaters.
Read on and see how Dolby Atmos differs from Dolby Digital, its direct predecessor.

Dolby Digital is a digital audio coding form that efficiently stores and transmits high-quality digital sound. Movie theaters first used this technology in 1992. It is now available for home video programming.
Dolby Digital programs deliver surround sound with 5 discrete full-range channels:
- Right Surround
- Left Surround
A sixth channel is also available for powerful LFEs (low-frequency effects), making viewers feel more than hear.
Dolby Digital audio can be used with laser discs, DVD-ROM discs for computers, DVD-Video discs, digital cable systems, digital broadcast TV, and direct broadcast satellite (DBS) systems. These discs usually come with the Dolby Digital logo.
The Dolby Atmos systems are the next generation of Dolby Digital and have delivered 3D aural and surround-sound experiences in theaters since 2012. Today, they have brought the object-based experience to home theaters.
Dolby Atmos is a system that places speakers above the viewers. It creates superior moving audio that streams around you for an absolute home theater sound experience.
With a Dolby Atmos system, speakers are positioned above the audience. It delivers sounds into a 3D space creating a feeling of being part of the action. It simultaneously duplicates up to 128 audio objects to create a mix of breathtaking, realistic, and rich sound.
There is a growing list of movies, content, and Blu-ray discs with Dolby Atmos soundtracks for home theaters.
Dolby Digital vs Dolby Atmos – the difference
When it comes to Dolby Digital vs Dolby Atmos, there are some key differences that you should be aware of.
For starters, Dolby Atmos is a newer technology that offers a more immersive sound experience.
Additionally, Dolby Atmos also supports object-based audio, which allows for sounds to be placed in specific locations in the room. This can create a more realistic and lifelike soundscape.
Finally, Dolby Atmos can also support high-resolution audio, providing an even richer and more detailed sound experience.

|Speaker Arrangement||Horizontal||Horizontal and Vertical|
|Audio Compression||2D surround sound||3D surround sound|
(3D space )
Both Dolby Digital and Dolby Atmos are multi-channel sound systems for home theaters. The format of Dolby Digital presumes that all speakers are at a level with each other. Dolby Atmos introduces the height concept (3D).
Dolby Digital assigns between 2.0 to 5.1 or more channels. Speakers are horizontally arranged. Dolby Atmos assigns between 3.1.2 to 4.1.4 channels with speakers arranged horizontally and vertically.
The first number represents the horizontal speakers. The second number represents the subwoofer; in the case of Dolby Atmos, the third number represents the number of vertical speakers.
With Dolby Digital, the sound is thrown to the intended speaker when an illusion of someone behind the audience needs to be created. This is because Dolby Digital is a speaker-based system.
On the other hand, Dolby Atmos does not push the sound to a certain speaker. Instead, it pushes the sound to a 3D space.
To create an illusion of a fighter jet flying overhead, no particular speaker where the sound will come is chosen. What is chosen is a particular 3D space, and the Atmos System will automatically adjust the sound that should come out of the right speaker.
Dolby Digital via its latest codec, Dolby TrueHD, creates 2D surround sound. Dolby Atmos renders a real 3D surround sound experience.
Both Dolby Digital and Dolby Atmos use sound enhancement tool software that delivers premium quality sound. Dolby Digital provides sound from your existing speaker set-up, while Dolby Atmos uses the software and compatible hardware.
This means that Dolby Atmos creates a superior sound experience than Dolby Digital because of the required hardware.
If you want to enjoy the best home theater systems, you need to invest in these minimum requirements:
- AV Receiver (home theater receiver)
- Projector or TV
- Surround Sound ( Dolby Digital or Dolby Atmos)
- Media player (DVD/Blu-Ray Player, gaming console, streaming box, etc.)
Which is better –Dolby Digital vs Dolby Atmos? If you look at the specs alone, Dolby Atmos beats Dolby Digital, promising a more realistic and superior movie experience.
Dolby Atmos is a newer technology that offers a more immersive sound experience with the ability to support object-based and high-resolution audio. If you’re looking for an unbeatable home theater sound experience, Dolby Atmos is the way to go.
