and if it's not too hard please add the possibility to query soundcard in/out latency pleeeeeaase!
i cannot see, how this should work in the real world.
why?
the latency of your soundcard is (as the term already indicates) heavily depending on your soundcard, which might not have a hook at all to query its latency.
all apis i'm familiar with (asio, jack, portaudio) provide api functions that can query the driver to get the input and the output latency ...
it's definitely possible to add this feature, it would have to be coded for every api on its own, though ...
cheers ... tim
