In this case, the recently appeared "true stereo" Love Me Do is the
work of a guy who has spent a lot of time separating the elements of
the only existing recording (mono) of the song using software tools.

The is fascinating!


Actually, the other two stereo mixes he created gained one comment each. The Beatles one, however, gained a lot of positive comments.
Who knows, maybe The Beatles mono mixes are superior to create stereo mixes from. Since he claims "extraction", he should have created a karaoke version, that would have been nice.

It's sort of blind source separation, but done by hand
by a human being rather than by a machine.

It seems like each one of the parts has been isolated along with the room
acoustics specific to that part, so the end result is kind of weird. You
can hear Paul along with the room reverb specific to Paul, panned to one
point. The effect is really very disconcerting and the individual room
sounds in mono coming from the individual parts is very unnatural.

But as an intellectual exercise this is very impressive and must have taken
forever.

I think it actually sounds pretty dang good, considering how it was
done. Certainly a lot better than those horrid Rock Band game
extractions from a few years ago. There are some audible phase-y and
gate-y artifacts which seem to be more obvious when listening with
headphones but I think it sounds better over speakers.


I bet adding just a touch of reverb would hide a lot of that stuff.

At this point I
look at it as more of a techno demonstration or parlor trick rather
than an artistic thing, but it shows that the technology is getting a
lot closer than it was even a couple of years ago.


The easy solution is the one I suspected at first: just hire a cover band
like 1964. They sound more like the Beatles than the Beatles did.
