Hi Mark,
I don't think this has to matter much, in
Ron's
case, for the musicians
since he mixes from a console and not from the
computer. As I understand his
setup, Ardour is just recording and delivering audio
data. However, I do
wonder how these latencies show up between a track
that was recorded by
itself, and then played back. The musician doesn't
know that the first track
is coming off the disk earlier, and that his new
recording is going on the
disk later, so the two should be out of sync by
2*latency, I think.
Additionally, there is some small latency through
the console and the
A/D/D/A and all. Does Ron have to nudge this stuff
to get it all back in
sync?
I recently asked about this on the jack and ardour
developers list. I think Jan replied by stating that
he thought jackd might be reading the period buffer
and compensating accordingly--if "-p 512" then move
file to compensate for the inherint latency of that
period.
Six months ago when I produced an album in Ardour, I
did a bunch of nudging on files but I think it was bug
related issues with Ardour that were causing peak
files to misalign. I'm not seeing that behaviour now.
I've got to setup a session but will come back to
learn more about the RAID latency issues that you're
outlining. BTW, I'm running RAID 5 but have thought 10
would be optimal for performance but expensive.

Cheers,
Mark
