Hi,
 
I am not sure where this post should find a home. Mods please move accordingly and hopefully I'm notified if it is moved and where.  On with the question..
 
Which Cakewalk software is best suited to take mp3's and clean up the sound? Also what software is best used in "remastering" commercial mp3's from LP's and CD's? 
 
Thanks 
 

Pyro Audio Creator can do that. So can Audigy. Pyro allows you to use VST plug-ins for EQ, Compression, Limiting, etc.
