There is jitter in the PC world and many different types but they obviously found ways to solve this long ago, much like in the communication world.
Again, it depends on the context. Jitter that is so large as to produce catastrophic bit loss does indeed have to be addressed in an all-digital system. And it regularly is. And indeed, in audio jitter is successfully held down well below the threshold where it is going to cause regular bit errors. In the bit error sense it is a non-issue.
As for the communication world, I just got done telling you that jitter is
a problem in that context. It is not a problem in every application but certainly ones that require wireless transmission and which push the spectral efficiency envelope. Is there a reason I should trust your words over my study and experience?
I will agree that I have the personality of a wet dish cloth and I snap when someone reads a high end audio article writen by old analog record guys saying how horrible digital audio is.
Will peer-reviewed AES articles do? There are a number of such articles on the audibility of jitter.
As I've said, I'm a skeptic, but not in the sense that jitter is totally inaudible, but rather in the sense that I think keeping jitter below audible thresholds is achievable---and is
achieved more often than believed. I also think that jitter is a scapegoat for other audible differences, real or perceived. I believe it was Chu Gai who recently noted that Julian Dunn, who has published studies on the audibility of jitter, suggested that power supply imperfections may actually be the cause of some of the audible differences often attributed to jitter.
As for "snapping", that's really the problem I and many others have with you. "Snapping", at least with the frequency that you do it, is simply unacceptable. We are trying to reshape this forum into a more civil place for discussion and debate---even about objectivist/subjectivist issues. You are more than welcome to participate in that reshaping by improving your tone. But as of now you remain one of the very bad apples we're trying to weed out.
