Dolby Atmos is an audio format for surround sound that includes a height channel in addition to the surround speakers typically found in a 5.1 or 7.1 channel setup.  This gives movie soundtracks a more natural 3D effect as sound effects and voices can come from or pass overhead.

How Does Dolby Atmos Work?

• Basically adding an overhead dimension allows film makers to add a new sensation of height to immerse you in the action, realistically depicting objects and sounds above you.
• That helicopter that hovers overhead in the film will now really sound like it is directly over you, the sound of dripping water from the roof of caves comes from above now.
• This added dimension of sound helps involve you in the film, you feel a part of the movie, that the action is happening right there with you as a part of what is unfolding.

What will I need for Dolby Atmos?

• You will require an AV Receiver that supports and powers a Dolby Atmos channel, these are marketed as such.
• One or two pairs of overhead speakers, either in/on the ceiling (preferential) or ones that fire upwards and reflect sound from the ceiling back down towards the seating position.
• Dolby Surround Source such as Netflix, Amazon prime or BluRay.

Is it worth it?

You bet, the increased immersion makes viewing movies on your home cinema considerably more enjoyable.
