I recorded a podcast recently, more specifically a friend recorded it on a Skype call. There were three of us on Skype and he used a call recorded to record all three of us. He sent me the file and when I play it in iTunes it plays perfectly, however when I import it to Garageband a voice is missing. Also when I click play in Garageband I get a digital "pop" before the audio plays. What am I doing wrong? P.S. The file looks really weird in Garageband too.
