Musicmatch--what are the steps involved

when I want to use Musicmatch to convert MP3s to WAVs with
DFX enhancement (which I find really helpful.)
Then burn those WAVs to a CD.

But somewhere in the process, I need to break up the (30 minute) file into smaller segments. How and when should I do this?
Thanks for any suggestion.

Instead of that bloatware you should try a dedicated sound editor like GoldWave or Audacity.
