Some comment on the article:
Can record fidelity out do CD?
Yes..... we can obtain higher ranges of capture above 22khz without aliasing.
(just keeping it simple)
Can it out do CD sound?
Yes AND No
So long as physical needles are being used, the vinyl fidelity will degrade some with every play. There are also factors to consider such as dust and other things getting on to the record. Stereo field work can also get tricky. These things lead vinyl to NOT out do CD sound.
At the same time however, we can now use lasers for reading the vinyl and this WOULDN'T degrade the record with every play..... so long as records are kept clean and played through something like optical rather than physically haptic means, vinyl CAN out do CD sound (and sustain doing such).
Here's a bigger question.....
Given the CD standard of 44.1khz sample rate and 16bit sound to yield roughly 80 minutes of audio....
Is there any reason for DVD not to have replaced CDs for audio rather than simply becoming a dominant physical platform for A/V gaming and movies?
Can vinyl out perform DVD sound?
Until the fidelity of common sound systems is significantly improved, I'd say this last question is pointless, because at 96khz sample rates/48khz response (24bit sound) we're already past the frequency response of common systems (granted, same could be said for CD to a MUCH lesser freq degree.....).
That's one of the single largest items I always found funny about the CD/Vinyl debates though.....
Lot of the DSP VS. Analogue synth debates as well.....
All this talk of "clarity" and "quality" and yet really simple signal principles like "what is the bandwidth of speaker" would be completely ignored. Can't count how many times I've witnessed debates and arguments on sound that I couldn't make heads or tails of because I was aware speaker/monitor freq response (or some other constraint) had imposed itself as a hard limiter/filter on what was being debated and turned both sides of the debate negligible.
Vinyl is back, no doubt about it. Sales of vinyl records have been soaring, although they still represent only a tiny fraction of the music industry's revenues: about 2 percent in 2014. Is this growth because, as some respected sources breathlessly state—I'm looking at you, Wired magazine—vinyl sounds better than digital media? Or is there some sort of retro-hype going on?phys.org
