Hi there -
What kind of latency should I expect out of a windows2000 machine running PD? I measured an impulse going through my laptop running PD, with the following patch:
adc~ -> dac~
and it took about 224msec. When speaking into the microphone, this "echo" is really noticeable. My laptop is a Thinkpad pentium750, 256MB, with the built- in soundcard.. Is there any way to cut this latency way down? I'd like to get it down to no more than 20msec. Or do I need a faster machine? Or Linux?
thanks, David Merrill

My expericen is that Win 2000 is the worst version window when it comes to latency. Win XP is much better or even Win98.2 has better performance.

you should try a lower -audiobuf settings...

I don't have W2000 running right now, but I _think_ I had about 60 msec latency going through it with a soundblaster, and about 15 when I put in an RME Hammerfall. However, I've never used any sound hardware that you could use on a notebook and don't know what you can get in that situation.
You can set "-audiobuf" as low as you wish, but the sound will break up when you set it lower than your soundcard and driver allow.
I didn't notice any difference batween W2K and WXP, although again the situation could be entirely different for laptops than on my desktop.
Hope this helps...

It seems that the Hammerfall DSP is working fine on linux and Windows. On OSX, I got the error -99999 at start up and it is impossible to get pd working ( audio ). If you have any news about that, let me posted. Thanks. My mac: 850MHz + OSX 10.2.4 Alex
