can i recreate the sound of vinyl by encoding the vinyl frequencies onto digital audio?

Lew here.  Sam, who is "not a troll" has been successful despite his near illiteracy in starting another useless vinyl vs digital argument.  Maybe that was his goal. Sam, in the world of science or even in the world of polemics, you need to state your experimental conditions, the equipment you use, the methods, and the data that you think allows you to claim such complete success.  That would require a couple of pages of writing with charts and graphs.  Maybe you can post that information somewhere else and provide a URL. If you're really only saying that you make vinyl to digital recordings, as Mapman and others have mentioned, and you think the results are identical to the vinyl source, join the club.  Lots of people think that.  Lots of people do that. There's a minor industry built around that belief and preference. (See Tascam, for example). You were not the first.  You did not invent the idea, even.  You can even find entire websites devoted to this sort of mental masturbation. If that's not what you are saying, what then?

Show us the way mapman!
You are so correct that 99% of vinyl of new music comes from performance recorded to digital.  So the vinyl contains the virus.  And nor can it sound better than the digital master except by adding artifacts that are judged to make the sound more pleasant.

It remains a pity that almost nothing new is now recorded AAA, even by believers.  Given the resurgence of vinyl, this is perhaps a seam that can profitably be mined.

Sorry guitarsam, my post was entirely clear and you add nothing by repeating your proposition with re-emphasis.
Put up or shut up with your backyard guitar.  Nobody's ever heard it.
So perhaps subject it to a double blind listening test.

Sad but true, although I am seeing a "market" for D2D but it is insignificant and just pursue by some people so this market is a boutique business which could be lucrative but not worth pursuing (from the money perspective)

Of course.

You can digitize all sounds. Especially the sounds in the audio range.
Typically sampling at 44khz (CD quality) is good enuf.
If you want to be really picky and claim you can hear above the normal human range of hearing, then sample at a higher rate and you will hear every pop, crackle, click and rumble, perfectly reproduced.
