I have about 20 songs (all given to me by the bands who recorded them, if you are wondering). I would like to make them a uniform volume and 'pump them up' as much as possible. I have a couple of ideas about how to do this (and I'm pretty far along with one method) but I know there must be a better way. I would be interested in any suggestions and advice from you knowledgeable people in this forum.

Ideally, the cheaper the software the better, but I am also interested in what you think would do the best job given that I am something of a novice and will have the manual open in front of me. That is, if it's more expensive but much easier to use . . .

Thank you.
