Hi everyone.
That's an interesting thread, there are questions here I never dared to ask (-:
I'm surprised though to hear that Pd could not become such a good realtime application.
from Word-Net: real-time adj : of or relating to computer systems that update information at the same rate they receive information
please note, that the word "latency" is nowhere mentioned. it has nothing to do with "realtime". (you can have a hard realtime system that has a delay of 1 week). so pd is by design a realtime system.
as for low latencies, the best i ever managed to get was measured(!) 4.5ms @ 44.1kHz, with plain OSS drivers (and lately with ALSA). this is pretty low for ordinary use. if you are doing music you should be totally fine with that. i guess only people doing technical dsp stuff (like echo cancellation) need to get lower latencies.
again: if you just want to record your trumpet and process it in real-time, i dare say that you do not need such low latencies. if somebody told you something else, they probably wanted to sell you something.
otoh, i am always seekings minimal latency too.
