Word Clock - what is it, and where is mine?

I have an M Audio 2496 soundcard atm (I know, haha). Anyway, just wondering what in the world is a world clock [in english] and where am I getting mine at the moment?

So you want to know where your clocking source is coming from without an external clock? Internally! Your running protools, so thats a pretty easy answer. As for what an external clock can do for your sound, I dont wanna open THAT can of worms again, although I am sure there are some on here that will regardless.

A world clock can tell you what time it is in any region of the world at any given time. You can find a good one at any watch or clock shop.

A WORD clock is a clock that tells your A/D and D/A converters precisely when a digital sample happens. If you dont have an external one, you are currently using the one built into whatever audio interface you are using (if youre using a digital-based recording system).

And, contrary to popular belief, going out and buying the best most expensive work clocking device will NOT necessarily improve your audio quality. If you only have one device handling all of your A/D and D/A conversion, its best to continue to use it's own internal clock, as this will result in the lowest possible jitter. It's only when multiple converters and other digital devices need to work together that external clocks become important.

I hereby declare that can of worms open.

(but I agree with you, though)

LOL! Hey, the audiophile is actually a pretty damn decent card for the money, don't knock it.

It's WORD clock, not world clock, if there is a world clock, then I want to know what it is too I think we may have to ask the Mayans about that one..

Word clock keeps digital devices in sync, by means of a master and slave relationship. You don't need to worry about it unless you have gear that is using digital connections.
If you have your 2496 say, and one other piece of digital gear, like a stereo effects box that connects via s/pdif, then you decide which is going to be the master clock, and which is the slave, make the appropriate settings in each device and they will then pass digital audio back and forth in perfect sync.
Without that sync, you will get some serious nasty white noise at worse, or really ****ing annoying clicks and snaps at best.

You can sync more than 2 devices from one master device if it has the necessary amount and type of digital outs to connect everything, but usually people buy a dedicated word clock whose sole function is to send the clock signal to all the digital devices in the system and keep them playing nicely together.

Not every interface has a word clock I/O, so you might not have one at all!

It's just one way of syncing up digital gear - so if you've only got one interface, you don't generally need to worry about it.

If you have 2 pieces of digital gear, and both have wordclock i/o, then you can use this as a clock source to lock them together - it's generally considered more reliable/less jitter than using the embedded stream in SPDIF or AES signals. Personally I've never heard the difference but there you go.
