Ex Machina DTS headphone x

Ex Machina, the first blu-ray movie with a dts headphone:x soundtrack is coming out. A few audio receivers and upcoming 4k blu-ray players support it, but is there any way to listen to this new surround mix in a Windows htpc?

Do you mean DTS:X?

Because a headphone soundtrack would just be a 2 channel soundtrack which can be encoded any which way since it's meant to be played through headphones.

DTS:X though requires a player that can bitstream DTS master audio. You cannot decode it on a htpc as DTS:x is object based audio which requires extensive setup prior to use for calibration. Any existing htpc Blu Ray software can bitstream it to a receiver since it's otherwise a normal encoded track, just like Atmos.

I had to download the Man of Steel DTS headphone x app on my Iphone so I thought with Windows I would need new software also.

If the Ex Machina BD contains a DTS Headphone:X track, then it's likely already encoded with their headphone virtualization, so you shouldn't need an app for playback. The DVD of Pearl Harbor similarly included a Dolby Headphone track, where the virtualization was already on the track, so it could be experienced by just plugging in a pair of headphones.

You have to remember a headphone track is two channels, so it depends how it's delivered.

If it's delivered through an app, then you need to download the app, probably run it to download the preprocessed tracks, then extract them from the app. Hopefully they will be in standard AAC or mp3 format, which can be played directly.

If it's on disc, then all you need to do is plug in headphones to your htpc,then select the headphone track on the audio menu of the disc. It's just a regular two channel track so no special thing is needed.

Preprocessed tracks take the surround programming, and send it through the HRTF downmixer (Dolby headphone, DTS headphone, proprietary systems) and recording the output as a two channel audio file.
