What is the difference between Dolby Atmos and DTS:X?

Dolby Atmos and DTS:X are two different audio formats used to create three-dimensional surround sound.

Both can reproduce sounds that appear to come from different directions, including above the listening position.

What do the formats have in common?

Both Dolby Atmos and DTS:X can use object-based audio information.

This means sounds can be positioned and moved in a three-dimensional sound environment rather than being tied only to traditional surround channels.

Both formats are mainly used in home cinema.

How do they differ?

Dolby Atmos

Dolby Atmos is common on streaming services, Blu-ray and UHD Blu-ray.

The format is also used for music and is supported by many modern home cinema receivers and soundbars.

DTS:X

DTS:X is mainly found on physical film releases, such as Blu-ray and UHD Blu-ray.

The format can adapt sound reproduction to different speaker configurations.

Do I need different speakers for Dolby Atmos and DTS:X?

No.

The same speaker system can normally be used for both formats, provided the receiver or audio processor supports them.

Which format is best?

There is no general answer.

The sound experience is affected by how the film or music was produced, which audio mix is used and how the audio system is installed.

A good Dolby Atmos mix can sound better than a less successful DTS:X mix, and vice versa.

Can all home cinema receivers play both formats?

No.

Check that the receiver supports the format you want to use.

If a particular format is not supported, a compatible alternative audio track may sometimes be available, but this depends on the content and equipment.
