iMovie allows you to separate the audio and video in to two separate channels, then just delete the video channel.

I use WireTapPro to extract audio-- I play the movie and WireTapPro grabs the audio for me and puts it in MP3 format.

caribiner, i'll have to look into that.

shouldn't it also be possible to run something like audacity next to idvd (not full screen) and record as you've got something playing in idvd?

obviously you'd be doing it in 1:1 time, but if you only needed a part of the audio, this should work, right?

That's exactly what WireTapPro does, Eric: pulls the audio while you're playing whatever media (it works great for recording streaming media, too-- we've done a couple of our podcasts over Skype and used WireTapPro to capture the audio).

I've never tried using Audacity this way, so I don't know if that would work. I'm not sure if you can redirect the input to come from the system itself. The key to WireTapPro is that it hijacks the audio coming out of your sound card.

I just tried it with Audacity, and I couldn't find the settings (in Audacity, System Preferences, or Utilities -> Audio MIDI setup) to reroute the internal audio-out to the internal audio-in.

I imagine I could use a stereo mini-to-stereo mini cable in the jacks on the side of my MacBook, but I imagine there would be an impedance mismatch.
