Apple’s new Apple TV 4K set-top box doesn’t currently support Dolby Atmos surround sound, an early review reveals. However, this is something Apple plans to add in a future update.
Atmos, along with competitor DTS:X, are next generation surround sound formats, referred to in the industry as “object-based surround.” In contrast to regular surround sound, which sends specific audio tracks to different speakers, Atmos lets sound engineers place their sound “objects” in 3D space, and then makes your sound system work out how to replicate this.
