Re: Question on using mp3gain

Yep... you hit the nail on the head.  I never really delved into the
specifics of what replaygain (mp3gain) was doing with regards to it's DM
reference levels and how they equate as far as real world loudness
goes.  My best guess is that I'll probably redo everything at their
suggested 89dB... see how things pan out there.  The biggest thing that
irritates the heck out of me is the fact that the audio coming out of the
digital out on the Audiotron is one HECK of alot lower than that of other
digital coax/optical sources I have... so if I switch the whole-house audio
source from AT to CD player or something, I have to run all over the house
to knock down the volume knobs quite a few notches to prevent being
evicted.. or eviscerated by the wife.  :)

Thanks, Brent.
