Get ready for Adventures in Space and Time with a special 3D sound mix for headphones – it’s virtual reality for your ears!

We’re delighted to confirm that a special binaural edition of episode 4 – Knock Knock – will be available on BBC iPlayer immediately after the adventure premieres on BBC One. That means BBC iPlayer users will be able to enjoy this enhanced version from 8.10pm on Saturday, 6 May.

The binaural edition delivers a 3D surround soundscape for anyone wearing headphones, placing the audience at the heart of the action! In other words, pop your headphones on and as you enjoy the adventure you’ll have sounds seeming to come at you from all directions, just as though you’re right there with the Doctor and Bill as they try to survive this spooky story!

Want to give it a try right now? The preview clip at the top of the page is from the binaural version. So, grab some headphones, double-check you’ve got them on the right way round (it really matters when listening to this immersive sound mix!) and click play. Great, isn’t it? And yes. Spooky, too… If you fancy running a comparison, this preview clip from the same scene is in standard audio.

So, from 8.10pm on Saturday, BBC iPlayer users will be able to enjoy the whole of this brilliant adventure – featuring David Suchet as the sinister Landlord – with an amazing 3D audio mix… Sounds good to us!
