Thanks for chiming in, Bob! I have quoted this example a few times
without finding out your point of view. It's good that you remember it,
and good to know it was our client who had the sharpest ears, or the
most picky aesthetic preferences. I never meant to imply that a tenth
dB is a routine adjustment! And with hardware processing it is common
to have more difference than that between channels of a single unit...
However, since that day I am using much smaller increments when trying
things in mixing and mastering my own projects, for example changing EQ
one dB at a time rather than wildly turning things up or down. As a
result I find myself getting to the ideal much faster than
previously...
Hope you don't mind me saying that your fine examples have been among
the most powerful lessons for me in audio, mentoring me to become a
much better engineer... even if this entire topic is not really about
archiving!
Thanks,
Lou
