Eddie,

In this case, I think I will highly recommend that you try a 'mastering' plugin and use the same preset across these 11 different songs. You may be highly surprised at the outcome being much more consistent than you would expect.

Did you buy Tracktion when it was $19 at Musician's Friend? If so, then you have Final Mix - which is worth much more than the $19.

Actually, even if you don't, I will do you a favor - send me a CD with .wav files on it of the songs and I will send you back a CD with 320 kbps .mp3 files, each in a folder for which I've applied a different preset or tweak of a preset for the 11 songs. It might take me awhile to get it done, but this might help out somewhat for you to appreciate the power of multi-band EQ, multi-band dynamics processing with limiting that most of these plugins combine with finesse.

To make this a shorter undertaking, perhaps limit the tracks to 3 of the 11; 3 drastically different sonic signature tracks.
