I need an easy way to take a stereo .mov file and convert it to a mono .mp3 or similar formatted audio file.
I use Ecamm's Skype Call recorder to record interviews, which I send out for transcription. The call recorder creates an .mov file with 2 channels--one for each side of the call. The transcription software only plays one channel, so the audio sounds like it's one sided.
I do this a lot, so I'd like a simple, one-step way to merge the channels and convert the file.
I've tried ffmpeg, which I like, but I'm only getting one channel when I do this:
ffmpeg -i call.mov -ac 1 call.mp3
Any suggestions? I'd like to use ffmpeg if possible, but a GUI app would be fine as long as it's pretty simple to use.
