I used Skype and Ecamm Call Recorder to record a podcast. Based on my last experience where I had a problem with echoing from my computer speakers into the mic, I decided to use headphones and a USB mic in order to record the call. However, when I play the .mov file back the conversation was recorded on two separate audio tracks. So my voice is on audio stream 1 and the guest is on audio stream 2. Is there a way for me to combine these two tracks without having to re-record the entire thing? When I converted the file into a .mp3 it seems that only the guest's side is captured.
