Hi,
This is slightly related to what Philippe just posted (Changing the
latency from within the render callback), but I'm wondering about
computing latency.
Are device and stream latencies constant, or might they change
periodically? Specifically, can I just compute it once in my configure
routine, or do I need to compute it and then register a callback for if
that param changes?
I also can't find any documentation on a stream latency property, but
people have mentioned using AudioStreamGetProperty to get it. Do you
pass in kAudioDevicePropertyLatency to AudioStreamGetProperty, or is
there some undocumented property that I should ask for?
Thanks,
Josh
