Levels in cubase 5

Hi all.
Some of you may think this is a stupid query but here goes…
I’ve mastered my backing tracks as mp3s but there’s differences in the levels between the files how can I get them so the levels will be level with each other?
Cheers all


The only one way is to put all of your songs to one project (in the ideal case it’s a WaveLab Montage), and set it manually. Relay on your ears only.
