When I recorded my audio, for some reason it only recorded in mono. I think it might be because I was using an older mic. But now when I try to play it in stereo there is only sound on the left side. I have Garage Band 3, so is there anyway that I can get that mono track to be on both the left and right side. Whenever I adjust the pan on that track it just makes the left side quieter, and the right side stays silent. This seems like it should be easy, but I can't figure it out.
