So I decided to go for it and download the DTS:X update.
My main drive was to find out if with the DTS:X 11ch call out clip how the overhead speakers would work. It has been documented that DTS:X will use some form of re-mapping to phantom image the front and rear heights. DTS thinks that the "heights" are at 45 degree and that "overhead" is at 60 degrees. When you have your system set at OVERHEAD the height call outs will emit from both the front left and right and the actual overhead speakers at the same time. It's trying to phantom image this sound at 45 degrees as it thinks your height speakers are really at 60 degrees. When set to HEIGHT only those height speakers will emit the height content in the call out.
Hope that makes sense.
When I play Atmos test tones for the heights, I get a reverse effect. When set to HEIGHT I get sound want to bleed front and back to better phantom image above you because the decoder thinks that the speakers have a super wide angle gap than if one were to use OVERHEAD setting.
So if you want 'discrete' height effects properly with DTS:X content, you must use the HEIGHT layout selection.
In my experience with my Yamaha 3050 and 5100 is that for Atmos you want to use OVERHEAD layout selection for the more 'discrete' sound.
Hopefully that makes sense.
Another thing that came up and brought to our attention by
was that some DTS:X clips were showing up in the information panel show a signal of 7.1.4 + 1 object. This appears on clips front the 2015 DTS demo disk: Divergent and Rio 2 and also on 2016 DTS demo disk: DTS:X All Around Us and Holly Miranda "All I Want Is to Be Your Girl".
My first though was "could these 1 object signals be a DIALOG stem that can be adjusted?". So I played back each clip and used the OPTION submenu on the Yamaha 5100 and found the DTS DIALOG CONTROL. I found that with pretty much all the DTS:X clips I have that this feature was locked out and could not be adjusted. Until I played the DTS All Around Us clip. There is a female 'presenter' commentating the clip. The DTS DIALOG setting was now unlocked and set to 0 with an arrow pointing right. I could adjust from 0-6 on the scale. With each notch up her voice and only her voice level was raised. This is DTS:X object-based audio dialog control at work, for real. The Holly Miranda clip had the same results. It is an immersive audio audio only track and with it a separate vocal stem that can be adjusted with the DTS DIALOG control. It worked. Just her vocals were raised. Now it doesn't like you have a full swing of level. It's just 0-6. You can't lower it, only bump it up in level. From what I could hear, it sounded like each notch was 1dB.
There you go folks. Object-based audio promised us we could take control of dialog/vocals independent of the rest of the audio mix and raise the level. If you have a Yamaha, did the update and have the 2016 DTS demo disk... I implore you try this feature for yourself.
Also, any of you that own a D&M product with DTS:X and has the 2016 DTS demo, I'd be interested if you could take advantage of this dialog control feature.
DTS:X decoding seems to be working. Tested DTS-HD MA 7.1 and could apply DSU. Also tried TrueHD 5.1 and applied Neural:X. Both worked like a charm.
Things just got interesting again.
