The latest sound technology will finally come to the best high-end streaming TV box.

This fall as part of the upgrade to TVOS 12Apple TV 4K will support Dolby Atmos object-based surround sound with iTunes titles, Apple announced on Monday at WWDC

It also said iTunes will have the world's largest library of Atmos titles, and that if a user owns a title that later adds Atmos, that title will get upgraded free of charge.

With support for Dolby Vision HDR video since launch, the Apple TV 4K is now the only media streamer to support both of Dolby's highest-end home AV formats.

While it's still the only separate streamer with Dolby Vision, Apple TV 4K is actually late to the Dolby Atmos streaming party. Roku has supported Atmos via the Vudu app for more than a year, as have the Xbox One, Nvidia Shield TV and a few other devices. Meanwhile Xbox One and LG Smart TVs support Atmos from Netflix.

Apple did not announce whether its Netflix or Vudu apps, which both currently support 4K HDR and Dolby Vision, would get Atmos support as well.
