It can never be better than the master.
If you don’t have a clean master you can not duplicate the original.
All you can do is guess.
I’m wondering if these printers don’t replace the local hardware stores. Need a replacement for something, just print one up.
Bob Carver, the legendary amp designer was one of the first to get “tube sound” from transistorized components by means of shaping circuits. Others have done similar work in digital to analog circuits, if one wants to pay dearly for the high end audio stuff. I dearly love Yamaha’s amps and receivers (even their low end stuff) for their utterly clean sound, even with the DSP being used to create their legendary digital sound fields(from digitally sampled echo info taken from famous public and concert venues).

I don’t think that it would. They aren’t really digitizing the music, they’re creating a 3D image of the record disk (at a very high resolution) then either creating an exact duplicate. The software can compensate for things like warpage.
Alternatively they can use the media to reverse engineer the device ( or at least critical parts of the device) necessary to play it.
Silentgypsy ~ Do you have to have a pristine master to do this?
According to the article, the software eliminates the little bumps from grit and smooths over the areas damaged by the stylus from repeated playings.
Since the groove is cut with a "V" shaped tool and played with a "U" shaped stylus, there is virgin vinyl above and below the worn contact points from repeated playings. I'd bet correcting the wear in the physical media based on untouched groove areas gives a more accurate rendition than having a computer guess where the tops of the worn areas are supposed to be.
Yes, once that's done it could be translated directly to a digital format, but only a philistine would skip making a replacement disc... ;^P
3-D printers didn't even exist when he wrote this story.
Mine too.
More cowbell...
I’m with you... Amazing!
There is a whole lot of awesome in this story.
For the stuff they’re working with there are no analog masters. They have a single copy, probably damaged, usually in a medium (like wax) that gets even more damaged if you play it. Technically they’re not converting from digital to analog, they’re scanning the lumps of the analog then making it again in a form they can play and not worry about damage, so while there is digital storage what’s stored is pictures not sound.
Yep.
Ain’t nuthin’ in the world that more cowbell can’t fix.
Don't feel like doing laundry? Brrrp-pffftt-zzzbppptt (printer sounds)... instant clean underwear for the weekend!
WE CAN REBUILD IT! WE HAVE THE TECHONOLOGY. The Six Million Dollar Rekird!
Why wash your dishes when you can just print up some more?
