'High Definition Vinyl' Is Coming As Early As Next Year (pitchfork.com)
An anonymous reader quotes a report from Pitchfork: In 2016, a European patent filing described a way of manufacturing records that the inventors claimed would have higher audio fidelity, louder volume, and longer playing times than conventional LPs. Now, the Austrian-based startup Rebeat Innovation has received $4.8 million in funding for the initiative, founder and CEO Gunter Loibl told Pitchfork. Thanks to the investment, the first "HD vinyl" albums could hit stores as early as 2019, Loibl said. The HD vinyl process involves converting audio digitally to a 3D topographic map. Lasers are then used to inscribe the map onto the "stamper," the part that stamps the grooves into the vinyl. According to Loibl, these methods allow for records to be made more precisely and with less loss of audio information. The results, he said, are vinyl LPs that can have up to 30 percent more playing time, 30 percent more amplitude, and overall more faithful sound reproduction. The technique would also avoid the chemicals that play a role in traditional vinyl manufacturing. Plus, the new-school HD vinyl LPs would still play on ordinary record players.
Well, to nitpick, Nyquist's theorem applies only to signals of infinite length, and in fact a 20kHz signal can't be perfectly reproduced with a 40kHz sampling frequency because you lose phase information on any finite signal.
I'm not for a moment suggesting that this actually adds up to a perceptible loss of information in the signal, or that 'transients' are in any way different to high frequency signal components, or that Vinyl is superior. I'm just nitpicking, because it's Friday afternoon, and I've nothing better to do.
I Analog recordings at best are equal to 32khz 24 bit recordings, and that's assuming you can get no hiss or feedback.
Ehm no. That is a misconception. 24 bit is overkill, even for digital (most `24` bit is actually no more than 18 bit, at most, and more likely 15-16). But as far sampling rate goes, (studio) tape reels happily go over 20kHz, and so does vinyl. You may be confused by FM broadcast, which has a 15kHz bandwidth. More fair would be to compare vinyl to '48kHz/16 bit'.
So people who think Vinyl sounds better, are full of shit, or deaf.
Define better. It sounds different, i think we easily agree on that. Mechanical issues, harmonics and more all play a role. If people say that it sounds better to them, you will have to accept that as a truth, since perception is subjective by definition. It's like saying 'you cannot find yellow prettier than blue, because blue is a nicer color because it has a shorter wavelength'. For similar or other reasons, some people do prefer tube amplifiers.
It's probably said a dozen times elsewhere in this topic, but personally i think the big difference between the vinyl vs digital `experience` is in the mastering. That's most likely why this 1970's old vinyl album of [fill in favorite band] sounds better than the 2005 cd release. Disclaimer: i am one of such people.
