For a school project I had to interview about a dozen people around the country. I used Audio Hijack Pro and Skype for the conversations. During the actual interviews, the sound was perfectly clear, but now I'm going back to take notes, and some of them are so distorted I can't even make out the voices. It sounds like when a cell phone is breaking up, with static that gets louder when you talk. Is there anything I can do to rescue these recordings? I'm hardly an audiophile, so I don't even know where to start... but my grade depends on this project, so any advice is greatly welcomed.
