In the spirit of the linked hogwash...
Live music does not exist. There is subway noise, air conditioning noise, people coughing, rich old ladies rattling their jewelry, bored husbands snoring and sometimes the trumpet players aren't sober, as can be seen by looking at them prior to the first note played. Just saying...

I never heard scratches, clicks, pops and hiss in a live concert.
Also all we know that recording studios are insulated of external noise and it is not necessary that performers play naked to avoid rubbing of their clothes when they move.
The matter is the current formats are defective, limited and corrupted.
The simple facts are that vinyl is noisy and digital audio has jitter, both flaws not from reality.
There is not noise and time base errors in the original analog master tapes that are not perfect either, but currently audio formats are far away of them.
So the terms AnoiseLog Vinyl and DiJitter Audio are right.
Jitter comes from the process of taking an event that takes place over an extended period of time and mapping it onto a fixed medium that takes up space, and then later taking what was stored in that space and mapping it back into an event that takes place over time. There is nothing special in regard to digital that makes it prone to timing errors. Every storage media has them, but different names are used. Tape has flutter. LPs have wow. Jitter is just a new name.

Please tell me which is the term used to indicate the time base errors present in digital audio?
The answer is in the Digital Domain Page: Jitter is time-base error.
Here is the site: http://www.digido.com/articles-and-demos12/13-bob-katz/15-jitter.html
Oh, another question but about noise.
Tell me please, why million people use headphones to listen to music?
Flutter on a tape transport is similarly a time base error. The time that a particular piece of tape crosses the head gap varies, e.g. because the capstan is slightly eccentric or because there is scrape flutter (the tape is vibrating slightly longitudinally). LP playback suffers from off center holes and warp wow, which in turn depends on geometry. Turntables suffer from the effects of bearing noise, which adds time base errors that modulate the music as well as rumble which is present even in the silent grooves.
Excessive use of headphones is a symptom of various problems, including a poor domestic situation and excessive multi-tasking. At its limit, the headphone disease is fatal, e.g. when the ambulatory listener steps out in front of a truck that he could not hear coming, thereby meriting at least runner-up status for a Darwin Award.

Hi Tony,
Yes, as I know and as you said Wow is a slow speed variation and Flutter is a higher speed variation also.
Those things are natural. Singers and musicians make wow and something like Flutter (tremolo) in their performances. And those terms does not have time base errors which as I know is a totally different thing and is unnatural.
As I understand in a compact disc there are dark tracks let’s say representing “zeros” and bright tracks representing “ones”. And those are not of the same length. A “zero” can be longer than a “one” and the next “zero” is shorter and the next “one” even shorter than the last “zero”, etcetera.
The reading of these longer and shorter tracks causes time base errors in sound and that is jitter and it is not in Nature.
And jitter I think has other definitions but in the past for wow and flutter was and still is speed variation and is measurable in terms of percentage.
Until now, jitter cannot be measure with accuracy, even nobody knows how could be measured. That is why you are not going to find a digital audio machine with a specification like this: Jitter 0.03%
Well, this is what I understand about jitter. But something worse to me is that the sound of Compact Disc hurts my ears in a moderate volume levels, causing me pain and even inflammation and after the listening I have some internal buzz that cease in an hour or two. With some cables this effect is less aggressive.
I wrote several years ago to Kevin Berg of Elusive Disc about the XRCDs that have less jitter than standard CDs and one of my questions was this: Do you know or have heard about the harm to the ears of CD sound to other people apart of me?
His answer: YES. I have heard the "JITTERING" in some CDs bothers people. I hear this complaint more with MP3s etc. XRCDs K2 Process was created to reduce the "jitter" affect.
Well I know now that many people have stress when hearing CDs and other feel some pain with MP3 with earphones.
Maybe in 20 or 30 years with many people with deafness, doctors discover that the cause is for listening digital sound. Who knows?
I think I will place a post about this in Digital Drive.
About headphones you are absolutely right. Those are not for streets, also people driving cars with their stereos at high sound levels and with closed windows are dangerous to them and others.
Headphones in home I think are for two situations:
1. For people that abstract from the real world trying to have the maximum concentration, avoiding the surrounded noise and other distractions and
2. Just to listen to music at relative high levels with freedom to not disturb the people in the house and the neighbors, or for both reasons.
The point is that music exists in reality even with noise, but most people do not like that.
And to me and many others the vinyl noise is annoying and it cannot be a high quality sound. If quality is the goal at least now Hi End Audio does not have it and for that reason the term is a fallacy and therefore does not exist.
Thanks for your interest in my comments and sorry for my bad English and please receive my best regards.
