Sky Q has supported Dolby Atmos since last August, but now it's come to Sky Cinema's vast library of on-demand films.
Dolby Atmos is a surround sound technology that originated in cinemas but is now found in high-end home cinema speakers. It calibrates the sound to fit the room, which allows it to place sound where it'll sound most realistic – if a plane flies overhead on-screen, for example, you'll hear the engines roaring above you.
Previously, it's been available for Sky and BT's Premier League coverage, as well as some other content. But its expansion into on-demand marks a big step for Sky.
Only some 4K on-demand films are compatible, however. And you'll need a Dolby Atmos-approved speaker (the Sky Soundbox doesn't support it, remember).
The feature was spotted by eagle-eyed AV journalist Steve May. Sky hasn't made any announcements about which on-demand films support Dolby Atmos, so you'll have to look out for a mention in the film's description.
