Sjoko, (yes, this is getting personal... :D )

In 2 other threads you told us that the quality of digital stands or falls with the A/D and the clocks 'but that is a different story'... love to hear it. Pleaaase? ;)

Thanks...
 
Since it has become personal, and doesnt pertain to "Other Equipment and Reviews", maybe you should take it to the cave.....
 
ahh yes clock!

All I really know is that timing is everything. he he- i just read that somewhere- i really don't know anything! lol

The better the clock, the lower the jitter, the better the sound. (I think I have at least that concept right!)

I have a question that Sjoko will probably be able to explain to us. Clock is a very grey area for me. What I understand of it, is that it is crucial in how digital audio is played back to us, as far as it's quality in sound. The question is then; is clock less important in recording to disk than in playing back from disk? does that even make sense?

I'm just not making sense tonite it seems.

I've come to the conclusion that the answer to my question is... no!

Actually James, you are making sense... I think it's both as important for the quality of the sound, but since recording is permanent, and playback will occur on different platforms anyhow, I would say it's more important during recording... The inaccuracies of both clocks will add up, resulting in addition of the incorrections. Which can be 'good' (cancelling eachother out) or 'bad' (doubling). And this makes it even worse cause now there's even a bigger difference between the both... Am I getting this right? Or are this last 2 sentences too far out. hehe... :)

Actually, I do have a vague idea of what this clock thing is all about. But I'd like to hear it in words. So I can go to the shop, and be a smarta$$. :D

Oh, by the way gidge, this is about AD convertors, and it's only personal because he brought it up. There's nobody else that seems to have known this allready... ;)
 
Sampling rate and word size are important as we all know. But the consistency of the clock source is what guarantees to accuracy of a sample to the actual signal. This is a big deal when you are using plug-ins to do effects because they are doing transforms on the slices of data with the assumption that it is timed correctly.

Here is a good article on jitter.

This will answer your immediate question.

To understand the basics of digital audio read about the nyquist thory or talk to a telecommunications guy like me :)
 
Hix, keep all foolishness in the Cave or I will "report this post to a moderator"....
