Dissecting DTS:X Press Release Claims



On April 9th 2015 DTS sent out a press release on their release of DTS:X.  It was all fine and dandy, but unfortunately there are too many things that needs clarification when comparing the statement versus Dolby Atmos.  So without further ado, here they are:

Unlike Dolby’s rival format Atmos, DTS:X doesn’t require a set number of speakers or specific configuration. Instead, DTS claims that its new technology is more adaptable and flexible with the DTS:X remapping engine able to support “any speaker configuration within a hemispherical layout”.

John Kirchner, chairman and CEO of DTS saiys: “Until recently, sound in movie theatres and in our homes has been dictated to by a standardised speaker layout. Through the use of object-based audio, DTS:X is able to scale immersive soundtrack presentations across a wide range of playback systems… this approach delivers the most authentic three-dimensional audio experience ever, making the audience feel as if they are in the centre of the action.

This is the same with Atmos.  Both DTS:X and Atmos don’t require a set of number of speakers or specific configuration.  You can use DTS:X and Atmos even if you only use a 2.0 system.  And as far as the remappin engine to support any speaker configuration…well, Dolby Atmos have that too.  It all depends on whether the receiver/processor manufacturers willing to implement that part of the techhnology or not.

moves objects to and through specific locations and uses the company’s license-free open platform, MDA (Multi-Dimensional Audio), which allows movie makers to control the placement, movement and volume of sound objects.

The statement above is no difference than Dolby Atmos technology.

A home cinema amp with a DTS:X decoder will be able to support standard DTS-HD Master Audio soundtracks found on Blu-ray discs, as well as the DTS:X mix where required.

According to DTS, its new decoder can “spatially reformat” 2.0, 5.1 or 7.1 content to make the most of the number of speakers in your system i.e. you’ll still be able to enjoy the DTS:X experience even when you’re watching content without a DTS:X mix.

Legacy home cinema receivers with a standard DTS-HD decoder will also be able to decode the new format, although they won’t be able to position the sound in the same way as a DTS:X-equipped amp.”

Once again, there is no difference between DTS:X and Dolby Atmos implementation and backwards compatibility.

With a DTS:X soundtrack and compatible receiver, you’ll even be able to control specific audio elements of the soundtrack. For example, theoretically you could “lift” dialogue out from background sounds, but only if the movie maker chooses to add this particular feature to their mix.

Like DTS-HD Master Audio, DTS:X supports lossless audio – up to 24bit/96kHz for object mixes and up to 24bit/192kHz for stereo and multi-channel mixes.”

Guess what? the exact same thing can be said about Dolby Atmos.  Theoretically Dolby Atmos can do the same thing too…but will the studio allow it to happen?  Most likely than not, the studio won’t allow you to do so albeit it is technically feasible.

Furthermore, Dolby Atmos already have at least 200 movies in the theatres mixed in Atmos whereas DTS:X is still as of this writing at zero title.

I’m not saying that Dolby Atmos is better or DTS:X is crud, in the end, as an end user, it is just the same thing with differing approach.
