Is Your Sound System Ready For An Evolution To Atmos?
23 Jun 2017
Dolby Atmos is an evolutionary step in the decoding of audio for movies. Atmos greatly increases the accuracy of motion within the theater by adding additional channels and changing the way audio is encoded.
Atmos creates a moving virtual environment through two main innovative sound features: audio objects and overhead speakers. It does this by using object based mixing. The channels are connected to individual audio objects such as sound effects or dialogue. Think of bees buzzing around your ear, a flying arrow smacking into the ground on your left, birds singing on imaginary trees all around you, a plane flying overhead…
Sound designers have separated up to 128 sounds so that they can be specifically sent to any location within any given space at any time. Sound objects will be sent to a 3D point in space and the Atmos system automatically adjusts to the appropriate speaker.
With this new technology they have also added a new way of indicating what kind of system is being proposed. In the past we’ve seen 5.1 and 7.1 configurations. The first number refers to the number of horizontal speakers and the second number indicates the number of subwoofers. Atmos has added a digit which refers to the number of vertical, or height speakers. The max configuration is 24.1.10 indicating 24 main and effect speakers, one subwoofer, and 10 height speakers. Most systems we’ve been installing in homes are far less.
The Atmos system is now more capable of tailoring itself to the home theater room. Instead of trying to recreate the sound system as we had to do in the past, now the system is catering itself to the home instead of the other way around.
The most significant benefit of Dolby Atmos at home is the addition of overhead audio. You can install overhead audio directly, or have Dolby Atmos-enabled standing speakers. These speakers feature an additional up-firing driver positioned on top in order to reflect sound off of the ceiling.
Here are the steps to get started with Atmos in your home. Start by upgrading the pre-amp or receiver to a Dolby Atmos capable version. Then, add additional speakers to the system if possible or replace the speakers to Dolby Atmos capable speakers which have additional drivers that bounce these Atmos channels off the ceiling.
