DTS:X is an immersive audio technology developed by DTS (now part of Xperi) that goes beyond traditional surround sound. Unlike conventional formats that assign sound to fixed speaker channels, DTS:X uses object-based audio. This means sound engineers can place audio objects anywhere in three-dimensional space, including above your head, and the format adapts automatically to your speaker setup.
The technology works by combining traditional channel-based audio (front, surround, and subwoofer speakers) with height channels and audio objects. Height channels use speakers mounted above ear level or ceiling-mounted options to create vertical sound movement. This gives films, games, and music a more realistic, enveloping experience compared to standard 5.1 or 7.1 surround setups.
A practical example: in a film scene with a helicopter, DTS:X can place the helicopter sound object high and to the side, making it seem like it's actually flying above and around you. The audio moves naturally through the space rather than jumping between fixed speaker positions.
DTS:X is supported on some Blu-ray discs, select streaming services, and gaming platforms. You'll find it on certain soundbars with upward-firing speakers, AV receivers with height channel amplification, and some home cinema systems. Support isn't as widespread as Dolby Atmos, but it's becoming more common in premium audio equipment.
When choosing a surround system, check whether content you watch (films, games, streaming services) supports DTS:X. You'll also need compatible speakers or a soundbar with height channels to experience the format properly. If you primarily watch mainstream cinema or stream content, Dolby Atmos availability might be more important, but DTS:X is worth considering if your preferred content supports it.
