Audio Latency Questions

[confus-ed]

You might want to have a look at this ... GeorgeBreese.com ... this particular 'George' is the guy who writes many of VIAs utilities & post chipset patches

The latency patches found there are more to do with pci timings & dma calls, than sound latency issues, but probably they might help with this problem.

Which makes me think ... just what is the problem ... too much latency (which you just 'allow for' don't you ?) or 'unpredictable' latency this 'usb jitter' Platypus mentions - in which case the above will help.

BTW ... if you ask me any setup that depends on s/w sound processing (i.e. by the cpu) is always gonna be more suscepible to latency, the less going betwixt the s/c & cpu the better .... but I see you are 'onto' that one

OK Now were thinking here lol
We are replaceing the motherboard due to some problematic issues we had during setup,{Displaying "Unknown Processor" } During boot,, untill bios was flashed.
Replaceing the ATI 7000 to a nvidia Geforce 4,,We had A Hell of a time getting the ati setup. The ATI card wouldnt even run at 4X without crashing.
Bought a higher end sound card THIS ONE
That comes bundled with a demo version of cubase SX.. We Have the full version.
Supports the E-WDM driver:
WDM and ASIO 2.0
Direct KS support for SONAR
OS: Microsoft Windows XP/2000/ME/98SE

The E-WDM drivers support Prodigy 7.1 for perfect compatibility with Windows XP, 2000, ME and 98SE while offering ultra low latency performance with all popular music production applications including Nuendo, Cubase, Cakewalk, Sonar, and Logic

I'll Post the results possibly monday,,, Probly gonna take that long for this headache to go away,, lol Ive spent 4 days trying to get this damn thing working up to par .
In The meantime,,, I'll check ut those other links posted more,,
Thanks TONS~!! for all the time you spent helping

Your new soundcard looks very interesting, I look forward to hearing of your results.

Although you might have things covered pretty well with the OS settings, this:

gives suggestions for XP optimisations for music, if you hadn't already run across it.

I googled a review of it AudioTrak Prodigy 7.1 Sound Card review ...

$100 looks good for this ...

OK,,,
Heres a quick update,
Its ALL About the sound card,, I would of NEVER beleived it possible,, BUT
The results have proven it .
Latency " 0 " .
The BEST we could acheive with onboard sound was on a stand-alone synthesizer
was 65ms. Any further,it would Click/pop during keyed notes.
When trying to real time edit and add effects,latency was around 150ms.
Now the good part,, We Got THIS Sound card,Stand-alone latency 0,,, On the Fly real time editting with applied effects,latency " 0 ". No POPS,crackles,Just pure clean sound.
Wasnt cheap either,, $145.00+tax.
Imagine,, the sound card costs more than the motherboard~!!
But HEY,, What matters are results,We Got Them,, FINALLY.
BTW,, the tweaks listed on this thread Im Sure are contributing also,And Id like to thank you guys for your help,

The Audiophile 2496 is an excellent card, as long as you don't try to run four together under XP...

Glad you've got such a good result. Sounds like you probably don't need any further tweaking, but just to mention, if you're running ASIO drivers, it's helpful to set Services to a high priority, as ASIO drivers run as a Service under XP.

Also when mixing, if you want a lot of plug-in effects (that is, in software not on the card's DSP), soft synths etc running, you can back off on latency to give the CPU more headroom. You want low latency for recording, but for listening to the mix, more latency doesn't matter much and is less demanding on the CPU. Does the card have on-the-fly latency adjustment?
