Editing mp3s in Flash?

[size=2]Is it possible to edit/cut frames in an imported .mp3 in Flash?

My problem is the mp3 that I have has a 3 second delay before the music actually plays. I can use a simple gotoAndPlay(); but the actual music doesn’t start until frame 55. Just wondering if Flash has the ability to cut/edit mp3s.

If not I guess I can just use the gotoAndPlay(55) in my preloader???
