a universal asio driver for any soundcards, i could succed to have something like 2ms latency on my pIII 800 mhz and a AC'97 onboard card !

you don't believe this yourself - do you ?

pd alone (without any soundcard) has a buffer of 3*64 samples which is > 4.3ms (at 44.1kHz)

i succeed to run with 2 buffer of 64 sample at 44.1 kHz probably not little as 2 ms (the value it returns with fruity loops about the driver only about the driver i have to notice), but damn more efficient than without this driver.. as an example:
talk in the mic -> adc~ -> dac~
before : to much latence then echo effect.
after : enough little latency for not notice any echo.

generally before i could not have something smaller than around 120 ms... so i still happy.
