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.
Alfonso
