Re: Question on using mp3gain

Yep,

I completely understand.  I do this stuff for a living (mp3, aac, wma,
etc...)... so the whole "make it as loud as possible" is understood.  Most
of my 120Gb of songs is of the metal variety... so we're talking 95 to
102dB for the most part on the source cd.  Since I'm usually listening to
these tunes either on my iPod or the house's in-ceiling speakers, I don't
need super duper mondo quality.  I mean, does it really matter if I am
missing some high end when I am jamming to tunes in the shower?  Maybe to
some... but not to me.  Anyway... thanks for the info.  Guess I need to try
a couple experiments when I get a chance.  I just picked 96dB for it's
significance to 16 bits of resolution for cd.

Thanks,
Jeff
