Reduce Audio Buffer

Hi All,

I'm working on a project at the moment that requires the audio to be bang on responsice to when I hit the keys. I've got my machine running stable at a buffer size of 512, but any lower and I get problems. What can I do to improve performance and get the buffer size lower? More RAM maybe? I've got 2gig at the moment, and all my audio runs through a firewire focusrite saffire le.

Cheers

Ben

if I understand you correctly, you are triggering audio clips from within resolume?
mmhh, the saffire should easily do better. what drivers are in use? which OS?
I'm running one machine with ASIO4ALL (realtek HD onboard audio chip) with a buffer of 128.

I'm using the most up to date drivers for the saffire, and I'm on windows xp sp3.It's not a massive lag, less than a second, but it's enough to put you off.

yeah well, a second is quite a lot in my opinion :| I guess you'll have to wait for someone with the same hardware to help you. sorry

Sorry, didn't explain myself very well there. We're talking milliseconds here, not a second, it's just too many milliseconds.

It's fine in audio software, I just have a slight noticable latency in avenue, and when I reduce the buffer to 256, I get a digital farting noise, so I'm wondering what else could be effecting it as I can pretty much rule out my soundcard - it's a decent one and performs fine elsewhere.

Cheers
