Intel motherboard with spdif input and spdif output

If I brought a Intel motherboard with spdif input and spdif output and then connected a AD/DA converter to the Spdif input and spdif output, would I be able to get 1 msec latency like this? at 96khz or 192khz.

thanks.

Audacity does have latency correction … http://manual.audacityteam.org/index.php?title=Latency_Test

That sounds really great and all, but It would be great if someone would be able to answer my question, Audacity is not the only audio program I use:) :smiling_imp:

Whenever somebody has questions about rare or odd hardware, the best we can do is present the options and tools for you to use. Nobody is going to buy that motherboard just to answer the question, further, most people, even if they do have that motherboard, want to reduce latency to zero, not tune it for a particular value.

If you do use the latency tools to reduce latency to zero, you can then use the same tools to perform an offset to get the latency you want. It’s a two step process.

Remembering also, that there are many delays in a computer system and only one of them is “latency” (hard drive management) and adjustable. The others are fixed in hardware and can’t be changed. This kills some people trying to sing to themselves or to an existing music bed. Not all computers can be made into digital audio workstations.

Why do you get the idea that I wanted anybody to go buy a motherboard, Everybody I have asked about this gets so defensive like they have something to hide from me.

But you know something I really hope I am right on this one, and if so intel are genesis for doing this, that would mean I can use any AD/DA convertor with a pretty cheap motherboard and not spend 1000 or more on a sound card just to record at 192khz with 1 msec lats or below.

And please let it fully sink in on what I am trying to ask here, like I said audcity is not the only audio program I use, and to top it off I am more a native linux user.

I’m trying to “let it sink in”, but it’s just not going down very well.
Is your proposal that you can connect an analogue signal (for example from your mixing desk) to an A/D converter, then connect the A/D converter to the S/PDIF input of your motherboard, then connect the S/PDIF output from the motherboard to a D/A converter and finally connect the D/A converter to your monitoring system?
The aim of this to get extremely low latency?
And you want to monitor sounds playing on your computer as well as the sounds that you are currently recording?

Why should that be any faster than using the D/A and A/D converters that are built into a sound card?

<<>>

Because you asked a question about system delays. We can only answer that if we actually have your system. Actual latency can be tuned to zero. Hardware delays can’t, so we’re back to experiences by somebody who actually owns your motherboard.

Ok you can both try this on for size. Maybe I should of explained things more, I use linux and windows, but I have programs in linux I would like to record with 1 msec latency at 192khz. I spoke to a few people about this and they all say it would cost alot of money, I would need a high end set up top gear expensive gear, which just did not cut it with me, so I started to think:)

In linux we will use Jackd to test latency, I can get 1 msec lats with my Audiomax 7.1 card at 48000hz it is just a pimped up express card,well that’s the way I see it on my motherboard, has I speacial slot on the motherboard but just looks like a pci express slot, it only supports 48000hz, now my Infransonic quartet can not get 1 msec lats in jackd it’s a Pci card, or I think it can at 48000hz, but above that it pops cracks, it goes all the way upto 192khz.

Then I have a pcmcia Echo io pci card, this can do 1 msec lats, but it breaks cracks pops after 66hz, this is with amd64 SSE2.

Ok in linux not many pci express cards are supported, it got me thinking intel HD motherboard can do 1 msec lats at 192khz through the mic input, but as you know they don’t have the best A/D D/A converters, the motherboard with spdif input output and then connected with my preference of A/D D/A converters does it make any sense yet?

don’t know any pci cards that can do 192khz at 1 msec lats, not had a pci express card yet to test, but there is only a few pci express cards supported in linux.

I just posted on here hoping somebody may have a motherboard with built on spdif in and spdif output, because with linux 1 msec lats is not as easy as it seems.

That’s where I’m getting stuck.
What programs?
What exactly do you mean by 1 ms latency?
Where is the signal coming from and where is it going to?
Why do you want/need low latency?

Well Jackd, Jackd with audacity, Sweep audio editor sound forge, and perhaps Ardour. I am finding alsaoss emulation works the best in some apps. I want to Dub mix and scrub audio, also have keyboard so really need as low a latency I can get for reaction time from my fingers.

How does that fit in with the S/PDIF business?

Because my keyboard is made of Acrade buttons, home made one, you don’t know the answer do you?

Your just skippin pass everything I have said, ignoring everything else and just picking at words.

You know what about Jackd with audacity? huh what about 1 msec or even sub mill secs huh?

Yes I know about Jack - I use it on Ubuntu, though I think that 1ms is rather ambitious even if you are using an rt-kernel.
What I don’t understand is the type of set-up that you are trying to create.
Yes, low latency is very important if you are playing virtual instruments from a keyboard and other such tasks, but nowhere have you said that you are doing that and how that relates to the S/PDIF connections that you originally asked about. I would sincerely like to help you out, but I’m not clear what you’re asking, so I sorry to say that I’m unable to do so.
