The BBC will release a special version of this week's episode of 'Doctor Who' on Saturday. Tune in to BBC iPlayer, and you'll be able to watch 'Knock Knock' with virtual surround sound.
This is done using a technology called binaural audio. It basically makes sounds appear like they're in front and behind you, plonking you right in the middle of the action.
Binaural audio has been developed by the BBC's research and development arm.
To get the benefit, you'll need to watch the show while wearing a pair of headphones. Thankfully, you don't need any special headphones, any old pair will do.
This Saturday's episode is called 'Knock Knock'. It's the fourth episode in series 10.
The standard version will air on BBC One. The binaural audio version will only be available on iPlayer.
The BBC has previously dabbled with binaural audio, but only for radio broadcasts. This is the corporation's first TV show to use the technology.
