Steve,

My sound guys (who are pretty knowledgeable) use Audacity for that. The only real problem we had with Audacity is that it does not save or convert wma files. But it works fine cleaning up MP3s.

How much is Sound Studio 3? I've never used it myself - I use Adobe Audition.

"The heart is the main thing in true religion...It is the hinge and turning-point in the condition of man's soul. If the heart is alive to God and quickened by the Spirit, the man is a living Christian. If the heart is dead and has not the Spirit, the man is dead before God." (J.C. Ryle)
