I don't know whether it is or isn't working directly off the Atmos soundtrack. All you need is a stereo output to output and record a post-decoded Atmos track. I honestly don't know what "order" everything is done in. First does it take the native Atmos soundtrack and headphone-ize it directly, within the Xbox One S, or does it take the 7.1 LPCM tracks the dolby soundtrack gets decoded to and use Dolby Headphones on that? If it's the second, I feel ripped off, because I bought this app to get the best surround sound on my Headphones without having to put up with the hassle of wiring and adjusting a surround sound "box" (don't know what the technical term is) for an asymmetric room where cats roam and like to chew wires and spend thousands of dollars doing it.
Then there's the second issue of DTS movies using a Dolby Headphone decoder. If it works off the LPCM 7.1 and converts THAT into Dolby Headphones, then that explains why DTS 7.1 and Dolby Atmos sound so close to each other when decoded into headphones using software decoding.
That's why I'm doing the test. I'm seeing if a pure Head-fi user can get good surround sound without having to buy "middle hardware"
If I can prejudice the results, the difference between Dolby Atmos and DTS is very slight, if any at all. But the difference between the Turtle Beach's X41 decoder, regardless of whether the source material is Dolby Atmos of DTS 7.1 has more extreme Basses (to the point of distortion) extreme trebles, clearly defined mid ranges, and more violent directional differences than the native Dolby Atmos Headphone Xbox One S app, in either Dolby or DTS source material. The Dolby Atmos seems more "centered" both in range and direction. It's like the Turtle Beach X41 decoder is on sonic MSG. It was designed to accurately pinpoint directions and more subtle sound differences are amplified.
And frankly, I like the Turtle Beach effect. It may not be realistic, which I might grant, but it gets results in games and makes you feel immersed in movies.
I could demonstrate it in audio MP3 files, but YouTube requires accompanying video, and an older version of iMovie is picky about the titles either fading in and out or if turned into a still, using a Ken Burns effect when none is desired, and being unable to change 40 scenes at once, and have to do them one at a time. I have only 400 kb/s outbound and need to conserve both computer processing time and bandwidth, and either the constant fade in and out, or the constant pulsating Ken Burns-ing is causing motion, adding processing time and bandwidth to the audio. Give me a little while, and I'll post 4 videos.
I would prefer posting them here on head-fi.org because it more accurately demonstrates the context of the recording to a Dolby Headphone encoding comparison. If someone can tell me why mp3s don't upload, and how tot fix it, I'd rather have the low, targeted profile of head-fi.org than to the worldwide spotlight of youtube. Common, an audio site with abilities to upload files, but no ability to upload MP3s? Who heard of such a thing? I'm hoping site admin can answer me other why or make MP3s upload.
