I thought Adobe Audition could sort out all audio problems, unfortunately I don't use it myself, but I thought there was the same filters and effects in it as there is in Adobe Premiere Pro? Now, here's a shot in the dark... AUDACITY, I think that's how you spell it, it's a free downloadable audio editor, try Googling that and it just might allow you to import the audio and duplicate it (no guarantees though).
