One other thing that this would be nice for is to raise the volume of cd that are mastered at different volume levels from other cds..

You probably wouldn't want to do this with equalization. There are two volume normalization methods available, but neither is currently part of the "stock" Empeg software.

The Volume Adjust kernel does dynamic compression so that quiet periods in songs (or quiet songs) will be normalized somewhat. It's not truly boosting the entire song, rather, it's figuring out where the volume should be so that the output signal's volume remains somewhat constant. A kernel with volume adjustment enabled is available bundled with the Hijack kernel at http://empeg-hijack.sourceforge.net/

In a future release, (possibly 2.0 final?) the Empeg guys say they will have track-by-track normalization so that when a track is played once, its peak level will be determined, and if that peak level isn't at a certain threshhold, a volume adjustment level will be stored for that track. This would be more towards what you're talking about, raising the volume of entire tracks or albums that are mastered too softly (mostly older CD's.) It kinda sorta made it into 2.0b3 but it was causing problems.

Tony Fabris will probably be along shortly to tell you that both these methods are mentioned in the FAQ.
