Dolby Atmos
George Lucas famously said that sound was 50 per cent of the movie-watching experience. With Dolby Atmos, we think it could be a good deal more.
Basically 3D for your ears, it’s the biggest thing in home cinema audio since the launch of Dolby Digital 5.1, and has opened up a totally new way for TV and films to deliver sound.
A big change in Dolby Atmos is that sounds become ‘object-based’, rather than ‘channel-based’ as in Dolby 5.1. With channel-based tech, the engineers could direct sounds to specific speakers. In an object-based system, audio designers can place individual sonic elements inside a 3D soundfield, with their movement and position reflected by the speaker arrangement. This technology, says Dolby, creates an ‘illusion of an infinite number of speakers’ and it can fully immerse you in the action.
