DTS:X Finally Ready To Take On Dolby Atmos

I feel like I’ve already got my hands full with five, six, or seven channels of audio and LFE, but now you’ve got the option of height channels and speakers that fire upward for a more enveloping experience.

The idea is to create a bubble of sound around by using dedicated height channels -- in essence, speakers aimed straight up at the ceiling, not horizontally toward the listener. Both DTS:X and Dolby Atmos soundtracks are available on standard Blu-ray discs, as well as the newer 4K versions. Rather than requiring cinemas and home users to install a set number of channels, object-based soundtracks are more akin to a globe as opposed to the "five points on a map" of a traditional 5.1 mix. Object-based soundtracks consist of a rendering in 3D space made of up to 128 channels, which are designed to adapt to whatever speakers are in a cinema in real time.
