As touched upon, Dolby Atmos is typically regarded as the better of the two. But that being said, both offer unique benefits that different customers might find appealing.
For instance, Dolby Digital is a surround sound technology that offers a highly captivating Dolby audio listening experience, which is why it has been popular and prominent for so long, however, it is less commonly used on new soundbars.
That being said, with 128 listening channels available, Dolby Atmos cranks things up a notch, and the 3D listening experience is one of the best audio options for enhanced home audiovisual applications.

Take your home theater experience to the next level with the outstanding quality and fidelity that Dolby Atmos provides.
Do Atmos and Digital Provide Surround Sound?
Yes, both Dolby Atmos and Digital provide surround audio. If you’re unfamiliar with the term, surround sound describes a system capable of producing an audio sensation from all directions, “surrounding” the listener which is easily available to experience with many different Dolby audio options around.
Traditionally, speakers could only provide sound in front of the listener.
Still, advances in immersive audio technology mean that surround audio provides a much more extensive and engaging listening experience.
Dolby Atmos gives users spatial sound, while Dolby Digital offers 5.1 spatial sound. But what does this mean for your home listening experience? Let’s take a closer look.
What’s the Difference Between 5.1 and 7.1 Surround Sound?
Most surround speakers – Dolby Digital included – are laid out in a 5.1 layout. It has five main full audio spectrum channels coupled with a low-frequency enhancement.
As such, it’s an ideal configuration for home theatre systems, providing good 3D sound for an engrossing listening experience.
However, due to newer technology, the use of more modern standards is being taken and will provide support for Dolby Atmos. The key difference lies in how the speakers, the way the left and right speakers are laid out in Dolby Surround vs Dolby Atmos, whereas a 7.1 system will split the side and rear sound effects.
As a result, the 3D sound offered by Dolby Atmos music is even more captivating than Dolby Digital, which is most attractive about upgrading to Atmos.
The bottom line is that Dolby Digital and Dolby Atmos provide exceptional sound quality.
Still, the spatial sound offered by Atmos is even more captivating, making it an attractive option to people looking to set up a home cinema.
What About Dolby TrueHD?
Another codec option for you to consider is Dolby TrueHD, which offers surround audio, as with Atmos. The key difference between the two is that they work differently, and it’s helpful to regard Atmos as an extension of TrueHD.
If a specific device is compatible with TrueHD and Atmos, the latter is usually given higher priority and becomes the default sound for most configurations.
If the device isn’t Atmos compatible, it will revert to TrueHD.
Fundamentally, TrueHD produces a sound almost the same as when it was initially recorded, offering exceptional sound quality.
This is why many movie theaters have Dolby TrueHD sound as standard.
If you’re looking to set up home theater systems and soundbars, you want to know the differences between Dolby Digital and Dolby Atmos.
Both offer exceptional 3D audio, but the increased features of Dolby Atmos mean that it’s capable of more immersive sound than Digital.
So, if you’re looking for the best of the two, a Dolby Atmos sound system is the clear winner.
