Dolby Atmos Vs DTS:X Vs Auro-3D Explained
There are three main types of software – codecs, to use the technical term – that allow your system to process surround sound. These are Dolby Atmos, DTS:X (the most common) and Auro-3D (highly specialist). We’ve actually got a full explainer for the three different types right here, but if you need a TL;DR:
DTS:X is probably the simplest. It doesn’t require a minimum number of speakers, and is purely software-based. It’s also got excellent conversion capabilities, turning even audio that doesn’t have surround sound mixing into something that can be put out through a surround sound system.
Dolby Atmos is a piece of software that uses height or ceiling speakers, and specifically requires them. You will almost never find this on setups below 7.1, although if you have the room size in the budget, it’s well worth experimenting with.
Then there’s Auro-3D: a highly specialised, deeply cool speaker setup that relies on something called the Voice Of God speaker, which is installed in the ceiling. This is the least common of the three, although its integration is becoming more widespread. 5.1 users definitely need not apply. Come to think of it, you couldn’t run a conventional 7.1 system through it either; by definition, adding height speakers would turn it into a 9.1 or even 11.1 system.
Just remember: knowing about these is helpful, but shouldn’t affect the system you pick. You should choose the right number of speakers for your room, and calibrate them correctly, rather than worrying about the type of surround sound codec. Consider this extra information.
