All you need is Audio Cleaning Lab 17 Deluxe. It has a built in MP3 encoder so you can export your material out, as well as functions to help you level out the audio output. This though might require you to do manually.

Each song you import from disc will be as an individual object. Each object has an independent volume control, so you can level the audio in that manor. Once completed you can export to the format you wish or burn back to CD or DVD.
