How Audio Pros ‘Upmix’ Vintage Tracks and Give Them New Life.

While the focus in the article is mostly just straight music tracks, some mention is made of music for movies, and so I guess by extension that would include games too. Anyway, it is remarkable what they can now do to pull music apart etc.

Well, there isn't a low bar for audio remastering, given that used to be shorthand for, "Subject it to the Loudness War".

So there's a high bar?

Anyway, OT: the article's text/information ratio... (do I have to continue?)
Sometimes, a mono recording is an artistic choice. Stereo placement isn't necessarily better.
I can think of many great artistic purposes for this technology, but in general - it makes me think of low-effort remasters of old games.

Depends who you ask. Are you asking these goons or the average person on the street?

Did I quote goons or average people?
Maybe I misunderstand you - are you actually saying that most music remasters are of such high quality (no low bar = high bar) that not much can improve on them?
Personally, I find the mastering stage overrated - unless it's done for practical purposes (removing volume inconsistencies between tracks on an album, adapting for LP, ...)

The reverse, actually. I'm suggesting the bar is so low that any actual attempt at mastering would be an improvement over shattering the dynamic range.

Hard, dare I say, impossible to improve on the perfect music track, but of course that is always going to be subjective to the listener.

So extracting or targeting specific instruments and being able to improve their quality or volume level or just to be able to turn mono into stereo into surround sound, can improve less perfect tracks or give a new experience with something familiar. Once again, all subjective to the listener's likes etc.

Much music out there, especially old is muddy, much new is compressed to suit a certain environment, often earbuds.

The user is empowered if they can be like a producer, such that they can tailor music they like to better suit their preferences or usage.
