The latest beta of tvOS 12 has included Dolby Atmos support for iTunes Movies.
One of the biggest and best features in the upcoming tvOS 12 update for Apple TV is Dolby Atmos audio. Throughout the betas of tvOS, however, there hasn't been a sign of it coming - until now.
Some of the films on iTunes Movies are now being upgraded to include support for the new audio system, ready for the tvOS 12 release in September. Apple have said they will be updating compatible movies with Atmos support, for free, when the newsoftware is out to the public. Currently developers are able to download the preview of tvOS 12.
Dolby Atmos support for films has been pretty irregular over the past few weeks, however it now seems it could be coming in time for the public release. We'll have more when Apple officially releases the feature.
