Cool Edit Pro doesn't exist anymore, it's been bought by Adobe and renamed to Adobe Audition:

It's a very good program, but it's quite advanced if you just need it for normalizing tracks. Try Audacity, which is much smaller and free:

MP3Gain is a good choice if you need a tool only for normalizing:
