So if you don't think analog tape is the bees knees you are not astute? I would argue most astute audiophiles have never heard unmixed and unprocessed audio on analog tape or high resolution digital but that is not what the topic thread is about.
vinyl versus digital redux
Has anyone compared the sound of vinyl with the sound of digital converted from a vinyl intermediary ?
I am referring to 'rips' of vinyl made with high end, high quality vinyl playback systems, with
conversion to high resolution digital.
I find it nearly impossible to distinguish the two results.
The digital rip of a vinyl record sounds identical...or very nearly so...to direct playback of the vinyl.
If one has 'experienced' the foregoing, one might question why digital made without the intermediary of vinyl sounds so different from vinyl. A detective story ?
We are talking about vinyl made by ADC (analog to digital conversion) of an amplified microphone signal and re-conversion to analog for output to the record cutting lathe, or from analog tape recording of an amplified microphone signal, and then....as above...via ADCl and back to analog for output to the cutting lathe.
Of course vinyl can be and is 'cut' (pressings made from 'stamper' copies the 'master' cut in lacquer) without digital intermediary. Such practice is apparently uncommon, and ?? identified as such by the 'label' (production)
Has anyone compared vinyl and high resolution digital (downloads) albums offered by the same 'label' of the same performance ? Granted, digital versus vinyl difference should diminish with higher digital resolution. Sound waves are sine waves....air waves do not 'travel' in digital bits. A digital signal cannot be more than an approximation of a sine wave, but a closer approximation as potential digital resolution (equating to bit depth times sampling frequency) increases.
If vinyl and digital well made from vinyl intermediary sound almost identical, and If vinyl and digital not made via vinyl intermediary sound quite different, what is the source of this difference ?
Could it reside....I'll skip the sound processing stages (including RIAA equalization)...in the electro-mechanical process imparting the signal to the vinyl groove ?
Is there analogy with speaker cone material and the need for a degree of self-damping ?
Were self-damping not to some extent desirable, would not all speaker cones, from tweeter to sub-woofer, be made of materials where stiffness to weight ratio was of sole importance ?
Thanks for any comments.

Seventies, I am a reel to reel and tape enthusiast; as it pertains to your question, disregard it; it's expensive, and there is a better way. I already have everything stored on "external hard drive". When I get a new CD, I down-load it into the computer, and it goes to the external hard-drive. Very rarely do I pop a CD into the player, I simply add it to the playlist on the computer. Presently I'm working on my third "down-loading" of LP's onto the external hard-drive. This has to be done whenever you make significant improvements in your analog rig and you want to enjoy them on computer playback. All of my CD's and my favorite LP's are stored on the "external-hard" drive and no lights have flashed to indicate that I'm running out of space. This is the third time for LP's; in other words, 3 times my collection of LP's are on the hard-drive because this is the third improvement. Now I have to "delete" the first two times I did this in order to free up space on the hard-drive. This is the computer age. I know very little about the things, but I have a "guru" who does. Fortunately this external hard drive thing is neither expensive or complicated. |
Orpheus, Mijostyn and Audio2design, I raise this issue because of disappointment with older albums re-released as 'high density tape transfers (HDTT's)' and 'remastered (? EQ-ed up)' recordings. In both instances the high frequencies are to my ear so compromised as to suspect misleading commercialization. Certainly, audio2design, audio tape can chemically deteriorate with time, and magnetic information degrades with repeated playback. To what extent is that information...particularly high frequency information....lost with time even if tape is of high quality and properly stored ? |
seventies I raise this issue because of disappointment with older albums re-released as 'high density tape transfers (HDTT's)'I've never heard of HDTT. Will you please explain what it means? In both instances the high frequencies are to my ear so compromised as to suspect misleading commercialization...What is "misleading commercialization"? To what extent is that information...particularly high frequency information....lost with time even if tape is of high quality and properly stored ?There are too many variables to answer this definitively. It really depends on the tape formulation. |
Well this seems to make sense, but am I oversimplifying? When the artist’s work is prepared for distribution, a vinyl pressing is made and digital streaming files are prepared. The digital streaming files will be identical to the digital mix prepared for distribution. The vinyl pressing will be as close as a skilled cutter of a spiral groove can get to it. Close, but never a duplicate. Some listeners really like the changes to the original sound that cutting the spiral groove introduces. So much so, that if they want to listen away from their turntable they would rather have a digital copy of the sound the spiral groove makes than the digital duplicate of the original mix. And the quality of that copy of the spiral groove can be so good as to be indistinguishable - showing that the ear can not distinguish a digital copy of an analogue sound. Is that right? |
