Removing Power Line Hum in GarageBand

I had made a video on removing hum in Soundtrack Pro a long time back. Last night I found I had never shared a version I made where I replicated the process in GarageBand for my author friend, Jake Bible.  So I tossed the video into FCPX to put a title and introduction on it then sent it on up to YouTube.


I cover how to remove power line hum, (120Hz) from audio using GarageBand. The technique is useful for removing any constant frequency from your audio. You can find Dead Mech at
