Dolby Digital vs Dolby Atmos

Dolby Digital and Dolby Atmos are two of the biggest names in audio technology. Both technologies provide high-quality audio experiences, but understanding the differences between them can be a bit tricky. Let’s take a look at what makes these two technologies different from each other.

What is Dolby Digital?

Dolby Digital is a digital surround sound format that was developed by Dolby Laboratories in 1991. It uses a 5.1 channel system for its sound, with five full-bandwidth channels (Left Front, Center Front, Right Front, Left Surround and Right Surround) and one low-frequency effects channel (LFE). The LFE channel is used for delivering bass frequencies from 20Hz up to 120Hz. This allows for an immersive experience that can be enjoyed on virtually any surround sound system or television set-up.

What is Dolby Atmos?

Dolby Atmos was first released in 2012 and is an object-based technology that works with both home theater systems and commercial cinemas. It takes traditional surround sound to another level by adding additional elevation channels so that sounds can move around the room with greater accuracy. This means that instead of just having a 5.1 setup with five speakers at ear level, you can now add height speakers so that sounds appear above you as well as beside you or behind you. This creates a much more immersive experience than standard surround sound systems are capable of providing.

Dolby Digital vs Dolby Atmos

The biggest difference between Dolby Digital and Dolby Atmos is that Dolby Digital is used for traditional 5.1 surround sound systems, while Dolby Atmos is intended for immersive home theater experiences.

While both technologies use digital signal processing to achieve their sound quality, they do so differently – with Dolby Digital focusing on creating a stereo surround sound experience and with Dolby Atmos adding additional speakers to create an immersive 3D audio experience.

In addition, it’s important to note that while both technologies are capable of providing high-quality audio experiences, they each have different applications and uses.

For example, while you could use either technology to provide background music for movies or TV shows, you would likely want to use Dolby Atmos if you wanted an immersive 3D audio experience for a video game or virtual reality application because it would allow for more accurate positioning of sounds in 3D space.

Likewise, you might opt for a traditional 5.1 system if you wanted to recreate the classic movie theater experience in your own home without having too much extra equipment taking up space in your living room.

Finally, it’s worth noting that some devices may support both types of technology – such as streaming services like Netflix that offer content encoded in both formats – while others may only support one or the other.

This means that when deciding which type of technology to use for your home entertainment needs, you should consider which type of device or platform supports each format before making your decision.


To sum up, when considering which type of audio technology is right for your needs, it’s important to understand the differences between Dolby Digital and Dolby Atmos before making a decision. While both technologies offer excellent sound quality experiences, they are designed for different purposes – with one being intended for traditional 5.1 surround sound systems and the other being intended for more immersive 3D audio experiences. As always, make sure to check which type of devices or platforms support each format before making your final decision!
