Dolby Atmos is a surround sound technology developed by Dolby Laboratories. It expands on existing surround sound systems by adding height channels, allowing sounds to be interpreted as three-dimensional objects.

[DTS:X is an object-based audio codec](https://www.whathifi.com/advice/dtsx-what-it-how-can-you-get-it), which aims to create a multi-dimensional sound that “moves around you like it would in real life”.
You may think that sounds a lot like Dolby Atmos, and youd be right. But where DTS:X differs lies in the required speaker configuration. While Dolby Atmos requires you to add extra overhead channels to your 5.1 or 7.1 setup, DTS:X works with standard surround speaker setups just like the one you might already have at home. It can support up to 32 speaker locations and up to an 11.2-channel system.
DTS:X like other higher quality DTS formats (e.g. DTS-HD MA) is lossless.

DTS-HD Master Audio is a multi-channel, lossless audio codec developed by DTS as an extension of the lossy DTS Coherent Acoustics codec (DTS CA; usually itself referred to as just DTS). Rather than being an entirely new coding mechanism, DTS-HD MA encodes an audio master in lossy DTS first, then stores a concurrent stream of supplementary data representing whatever the DTS encoder discarded. This gives DTS-HD MA a lossy "core" able to be played back by devices that cannot decode the more complex lossless audio. DTS-HD MA's primary application is audio storage and playback for Blu-ray Disc media.
