I have not used it but in the Soundstream section of EZCD 5 has a normalize.
"Records all tracks at equal volume. Select this option if you are recording songs from a variety of sources that have been originally recorded at different volumes. If you do not select this option, some tracks may sound louder than others on your CD."
Open Soundstream by choosing it from the top of the create music cd section of selection window Then click on the blue (show option drawer) button at the bottom center Then choose effects. Lots more info in instruction book and/or help files.
