I see no use for meterbridge in JAMin. We've already
got good metering.

I am not the originator of the request. Joern relayed
his experience and suggested a solution for detecting
problems. Because it doesn't affect audio processing 
it is an easier feature to be in favor of. In
comparison your proposals for low, mid and high delays
are much more complicated. And I imagine you're tired
of arguing about it.

My silince on the proposal isn't an act of
ungratefullness or a lack of interest. I simply don't
know but I did ask Steve about it on IRC. I forget
what his response was.

I'm curious about the results you're getting by
routing through the BBE. Can you adjust the delay
amount realtime and if yes could you create an example
where you slowly sweep from no delay to the right
amount of delay and then beyound where there's to much
delay? If that's reasonable sweep slowly enough and
hold in each setting long enough to adust our hearing
and try to analyze what's happening.

How many milliseconds of delay do you suspect are
inherent in our processing chain?

Are you suggesting the latency is inherent in software
or not until it hits audio card hardware?

I am accutely aware of the negative affect that timing
and sync have and how phasing undermines amplitude
response.

If "delay" is a real problem in mastering do you have
any thoughts on how it's affects Ardour? It seems to
me that there can't be any difference between it and
JAMin. In fact phasing should be more apparent in
Ardour simply because of the track counts. Right or
wrong?

I guess it makes me wonder how hardware manufacturers
like RME or M-Audio deal with delay on wire. Do they?
