You could try the Audio Processing plugin

although that wouldn't necessarily be the best approach.
Start with trying to fix your files with MP3Gain (assuming they are MP3)
http://mp3gain.sourceforge.net/
Keep a copy (just in case) but I've not had any trouble with this.
Read CAREFULLY about what it does as you may or may not wish to treat files as collected into albums.
