These vu-meters, clipping LED, etc. should all be reported as read-only
parameters accessible via the ordinary property APIs for AudioUnits.
The internal DSP of the AudioUnit may set these parameters in real-time
for the UI to display. What we want to avoid is people adding extra
hacks like accessing C++ objects directly or adding C APIs.
If there's something we've neglected in the standard APIs, then lets
address the issue cleanly.

Hmmm...
We'll, I'd be careful here. [...]
The situation that I describe is a reality. Great numbers of
existing market plugins provides vu-meters, clipping led, that are
computed to a particular stage of dsp processing.
It appears then to me that this should become as a standard part of
the SDK, isn't it ?
Suppose that Apple decide to run the dsp code in another process (as
it is done in BeOS for efficiency) ; the solution that we are
talking about would not work then...
