"Upmixing" is new AI driven technology that allows single track original recordings to be reprocessed into multi-track, heretofore considered impossible.
But AI can do it.
I still remember the first time I plugged a Commodore Vic 20 into our living room TV 40 years ago and started typing. After about an hour, I said out loud to my family "this changes everything"...
-------------------------------------------------
Abbey Road Studios programmer invents AI driven process:
The challenge dropped him at the leading edge of a field known as upmixing, in which software and audio engineers work together to transform old recordings in ways that were once unthinkable. Using machine learning, engineers have made inroads into "demixing" the voices and instruments on recordings into completely separate component tracks, often known as stems. Isolating the components of songs is a surprisingly hard problem-more like unswirling paint than using a pair of scissors.
But once engineers have stems, they can take the isolated tracks and "upmix" them into something new and perhaps improved. They might enhance a muffled drum track on an old recording, produce an a capella version of a song, or do the opposite and remove a song's vocals so it can be used as background in a TV show or movie.
I can't wait for some new remasters of Szell recordings! Sign me up!

Can confirm. Was the family.
I got the original ZZ Top - LaGrange without the echo on the opening drums. It is better.
I got the old and new versions of Kenny Rogers - The Gambler and the original is better, it sounds more real.
The remix of Gary Wright - Dream Weaver was a fucking disaster, but the song was not all that great to start with.
Some remixes are goo however, no doubt. When you got a DDD CD it is newer, and totally digital. It has never been analog. Then AAD is when they find original tapes but they are already mixed down to stereo. The only thing they can do is EQ and echo, and please no echo. An ADD disk is one where they got the original eight or sixteen track tape, and digitize all the tracks and remix them all in the digital domain, hopefully staying loyal to the original mix. So if you have a bunch of CDs,look at them, you might already have about the best remix you are going to have.
If they do this complex logic on the material I do not have alot of confidence in it being faithful to the original - i.e. the definition of high fidelity. That is also why these surround receivers are junk. They do not put out what was put in, instead there is all kinds of digital delay applied and all this shit. And I think all that shit sounds like shit. If I want a delay I'll, hmm I dunno. shoot myself.
watched a similar thought destroy several Miles Davis recordings! Leave them alone and buy a mono cartridge instead

I should listen critically sometime to the Beatles original mono mixes, haven't really ever done that even though I basically know all their albums by heart at this point.
Anyway it is a money making opportunity for the rights owners, so good luck trying to prevent them from new releases ad infinitum for any excuse they can think of...

Think there might be a vinyl boxed set?

Someone will, of course, have to modify the lathe to run at 22-1/2 rpm.

And don't forget Three Dog Night :)

Just kidding.
musicians were setting in a circle with one mic in the middle of them. How does one fix this without screwing the pooch?

Along similar lines, the JBL Synthesis SDP-55 preamp/processor has "Logic 16" capability, which "will up-mix any input source from mono up to 15.1, including all Dolby formats with natural astonishing 3D sound. In addition Dolby, DTS Neural:X, and Auro 3D upmixers are on board." Yeah - I've ALWAYS wanted to hear Toscanini and Caruso in the 16 channels they deserve! ;-)
Ready to pull the trigger as soon as I determine what my tax situation for this year is. I want one! I want one! LOL!
Nice pic! Price?
The price is $6,000 - not out of line in comparison to other MCh preamp/processors around today. When this unit originally came out, it did have some problems - which have now apparently been solved with the latest firmware upgrade.
For every remastered recording I've heard that improved the original mix, I've heard about ten that made it worse...... Too many "enhancements" to the mix end up undermining the music......
Count yourself lucky!
You have a much better success rate with remasters than I do.
The scary part is there are a lot of overprocessed remastered recordings without any mention of "remastering" on the album cover......Just two weeks ago, my friend purchased a Bob Wasserman "Duets" LP..... It was not an original pressing, there was mention on the plastic covering that it was an "audiophile" edition, but otherwise no mention of "remastering" on the album cover itself..... The vinyl was warped, so he loaned it to me and I flattened it for him..... After flattening the LP, I was curious about the music, and immediately noticed the Auto-Tune applied to Aaron Neville's voice in the opening "Stardust" track...... I told my friend the bad news (he hates Auto-Tune worse than I do), and then sampled the tracks on YouTube..... It was indeed a remastering artifact.... The original pressing was fine.
I ended up buying a first pressing CD, and it too was fine..... My friend then got an unadulterated CD for himself.

You can be a Luddite if you want, Todd! I'm willing to take the chance! ;-)
the evals will be told someday, and I'll await the yes's and no's. It will be more fodder for places like this one.

FWIW, I did buy a re-release of Flim and the BB's "Tricycle," on vinyl..... (I think these albums were released exclusively on CD prior to this.) So I guess I'm guilty too.......
(1) if they will materialize, (2) if they will be listenable, and
(3) what's wrong with mono?
