If you're developing a closed system, then why not just write the
applications to do what you need?

(A quick overview of the project, in case it helps. This is a multi-
media kiosk display system consisting of a player app plus "helper"
apps to play QuickTime files. The helpers run as separate processes
to prevent QuickTime instabilities and memory leaks from messing with
the player. The player can also be operated via a remote-control app
from another computer, where the kiosk itself is not visible, so I
need a status display showing video and audio are actually being sent
to the kiosk. Ideally I want the player to directly sample what is
going to the hardware, partly because the actual playback is done by
separate applications, but also to allow a remote operator to detect
any possible glitch, i.e. the screen-saver being activated. This is
easy to do with video by just grabbing directly from the Core
Graphics frame buffer. I'd like to do something similar with audio;
but if that isn't feasible I could live with having a helper app
monitor it's own audio and report the result to the player.)
Again, many thanks for any help you can provide.
