DTS X Resources – The BigScreen Cinema Guide

"DTS:X is built on the foundation of providing an open, adaptable solution for content creators, cinemas and homes to fulfill our goal of bringing immersive audio to as many people around the world as possible," said Jon Kirchner, chairman and CEO of DTS, Inc. "Until recently, sound in movie theaters and in our homes has been dictated by a standardized 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, from efficient to extravagant, while staying true to the content creator’s vision. This approach delivers the most authentic three-dimensional audio experience ever, making the audience feel as if they are in the center of the action."


DTS:X also will feature dialog control, which will allow the user to control the volume of specific audio elements, such as dialog, if they wish. This is something that has to be enabled by the content creator, since the dialog needs to be added as an object which can be so controlled. While many are seeing this as a way for people to be able to boost the dialog to accommodate their TV speakers/soundbars, we imagine that such a feature could be used to isolate the announcers of a sporting event, where they could be muted while still allowing the game and crowd sounds through.

Since not every movie has a DTS:X soundtrack, an upmixer is offered, called Neural:X. Basically, it will take a multi-channel soundtrack and attempt to place sounds into the height channels by extracting what it believes to be height-based content. This will be similar to Dolby Surround, which is Dolby’s Atmos upmixer. Like all upmixers and DSP effects that try to make something that isn’t really there, the success may vary from movie to movie. DTS:X vs. Dolby Atmos

While there are some differences in the exact number of objects supported, both formats are more similar than they are different. Furthermore, it is expected that the differences that do exist likely will be limited by their implementation in consumer-grade A/V equipment. For example, there are many A/V receivers that decode Dolby Atmos, but none of them decode more than four height outputs, even though the format supports up to ten overhead outputs.

Much like Dolby Atmos adds special coding to a lossless Dolby TrueHD soundtrack on a Blu-ray disc, DTS:X adds a layer of special coding to a lossless DTS-HD Master Audio soundtrack. This means that a movie with a DTS:X soundtrack will be backwards-compatible with any Blu-ray player and any receiver capable of playing DTS-HD Master Audio soundtracks (which is every Blu-ray player we know of, and most every A/V receiver made in the last five years or so).

This is different than DTS-HD Master Audio, DTS 6.1 or 5.1, and DTS Stereo. Look for a designation on your source material for the specific notation of DTS:X. Currently, DTS:X is only available on Blu-ray and Ultra HD Blu-ray discs. Check the list of movies above to see which movies have DTS:X soundtracks. Make sure that the DTS:X soundtrack is selected in the menu of the disc you are playing.

You should not need a new Blu-ray player. In order to send a DTS:X signal, your Blu-ray player must be configured to send audio via "bitstream" in its settings menu. Additionally, any setting for "Secondary Audio/Mix" or similar should be disabled. Any Blu-ray player capable of bitstreaming high definition audio should be able to deliver DTS:X.

High definition audio cannot be sent over toslink or digital coaxial audio connections, you must use the HDMI cable connection. Many TV’s with ARC (audio return channel) capability over HDMI cannot send high definition audio from the TV to the receiver/processor, so an app on the TV may not be able to deliver DTS:X or other high definition audio.

Your receiver will need to be configured correctly so that it knows how many speakers you have and where they are located. If you do not do this, you may not be able to engage DTS:X playback even if the receiver/processor is capable of it. For help with configuration, check the manual for your device and/or enthusiast forums like the AVS Forum for discussions relating to your specific device.
