I read through a bit of this and wondered if/how the jack meterbridge
meters might help show the levels of reconstructed audio. From the jack
meterbridge webpage ( http://plugin.org.uk/meterbridge/ ), I read the
following about the VU meter:

<quote>
The -r flag (set reference level) is usful with these meters as it will
allow you to calibrate to your DA converters. The meter is pre-adjusted
so that it should allign correctly calibrated DA converters with
analogue systems. If you wish to run with 0dBFS = 0dBu then use "-r 20"
</quote>

Am I interpreting this to mean that the VU meter should be able to give
an estimate of the levels of the reconstructed signal?

I'm using a Delta 1010LT - can anyone point me at info about the DA
converter calibration procedure, or, better yet, what the "-r" value
should be for this card out of the box? I'm just beginning to look into
this, but tests with a tune I'm mixing shows quite a bit of it is "in
the red" on the VU meter, even though the digital meters are running
below 0dBFS. I want to make sure I'm looking at the right thing, or if
I am totally off-base.

Thanks!
