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

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...

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
