Perhaps you missed where He mentions Movie and Tv use in his 2nd paragraph. Only until I asked him in post #31 did he define usage breakdown. So, I was under the initial impression that this was going to be a mixed usage setup. I only wish Thread Tittles were all accurate.
This was his 1st sentence. Leading me to further think that this is not just a 2 channel stereo setup.
My understanding of “individual” sound is separating the lead guitar, the piano, the drums and the singer. This is what was done in the film Get Back and the album Revolver 2022 Mix. They used AI and the process is not real-time.

Truer words never spoken !!!!!She is most definitely a Keeper!
Correct. I will get an AVR anyways because of build in streaming, room correction and bass management.
Yeah, it was something like this! I remember him talking about coefficients. The box he built to do it was all analog, custom PCBs, etc. I remember he explained how it had digitized pots controlling a resistor ladder to adjust settings and segment displays reading out the numbers. He had an AP Sys-2722 so I assume it was well-implemented. He had some sort of (MIDI?) interface in it as well so his computer would adjust the presets song-to-song for personal preference
The combo of the realization you are doing this all in Q-Sys and the tools on the felt just about gave me a panic attack LOL.haha too funny !!
I get accused of being a bit eccentric too.... thank providence for a beautiful wife that helps me defend this DIY mess to guests!
Of course they don't do that. They separate "individual" sounds based upon location. If they're mixed to the same location, the upmixer will put them in the same location. If the piano (or pipe organ, which is often the case) is behind you, it will place that individual sound there, where it should be. If most of the room reverb/ambiance is coming from behind you, they should place it there.
How do you locate a sound as behind you on a stereo track?
seems like an easy fix is to have the center for surround, then see how stereo sounds with it. if you don't like it, take it out of the upmixer config and just use it for surround.
I'd have no chance if it weren't for flexible DSP like Q-sys, and the relative simplicity of using linear phase Lol.
Nice looking setup, i bet it sounds great.
Largely phase manipulation. It can be done artificially or naturally. Watch this video with Dobly Surround Upmixer on:
You could do it with software (Acourate, etc...) But I have always hated the thought of a Windows PC being the "heart" of the system. Q-Sys is way more elegant. Shame they are killing off their traditional I/O options and essentially forcing the consumer to buy networked amps or their under-performing I
Of course. Total pipeline latency needs to be kept at a minimum at these things because of DJ beatmatching and tight audience proximity. Festivals are easy to get away with FIR because the audience can't hear the stage monitors/iem feeds. As long as there aren't so many taps used that it starts to visually become an issue (but nowadays, with the IMAG screens, the video operator can just delay the live feeds and fool 99% of the crowd since almost everyone watches the screens)
The video is unavailable but you didn't understand my question. You said "If the piano (or pipe organ, which is often the case) is behind you, it will place that individual sound there, where it should be." How can the piano can be behind the listener on a stereo track?
I understood your question perfectly. You didn't understand the answer. Hear it happen in the above video (just as one great example). I just tried the video on three different devices, it plays fine on all of them.
A shame, that was a Chesky Records recording with David Chesky walking a circle around the mics playing a tom-tom. Very cool with an upmixer.
No, your question was how it was located on a track. I told you. My whole point was it works dramatically better with an upmixer and more speakers than it does downmixed into two speakers. With only two speakers, depending upon your speakers and your room (because you're attempting to use the room as additional speakers) and how susceptible your ears/brain are to psychoacoustic tricks, you may kinda-sorta-maybe hear a similar effect. That's what the artist who mixed the track and put the decorrelated signal in there is counting on.
OK, I understand but you must admit that is a specialist example. How many stereo recordings rely on psychoacoustic tricks that upmixing will uncover? Besides, if you are mixing the stereo track specifically for upmixing, why not master in multi-channel in the first place?
Listening to it in an environment other than that in which it was originally mastered, also alters the mix....
Yes, DSU and DTS upmixing both do a good job of extracting phantom center. The result is significantly clearer center vocals. Auro3D does some extraction but less. However they all do other things as well so whether or not that's better is up to you.
Phantom center is quite literally a psychoacoustic trick that upmixing can easily recognize. So, lots of them.
