In order to keep our costs down and the quality high, we record the Ask Different Podcast as a double ender where each party does a local recording and they're sent to me after the show to edit. I also use ECAMM Call Recorder to record the entire call, and I sync the separate audio tracks by hand to that recording.
Because the process of lining up the clips is tedious and error-prone, I'm wondering if there's a more automated solution. Since the recordings aren't exactly the same in terms of quality, whatever process that performs the action would have to make a 'best guess' as to the alignment of the tracks.
