Is there any software that would help me to normalise by music

like to get some consistency while I'm going through all my CDs and
making MP3s.

Why stop there ? As your music will have the same dynamics, loudness, and
tone, there remains one item not addressed - the notes. You should
normalise all the notes and words ( I guess that's two items) to be the same
as your 'reference' . Then your mind will not be stressed by the
differences.

In fact you could save time and effort, and just repeat the one track ad
infinitum !
