I can hear you! Extracting audio from video files might seem like a hassle. There are many methods that are just that, but I’m here to show you a very simple way to save out the audio from a video file. First of all, you’ll need to buy Quicktime Pro. I KNOW, I KNOW! $30 might seem like a lot, but it is worth it. Trust me. Next, load your video file in Quicktime 7, and press CMD+E.
Now select the Export drop-down menu, and select Sound to AIFF.
Now press the Save button, and you’ll have the raw audio sitting on your desktop. You can now edit or process the audio in programs like GarageBand, Audacity, or iTunes.
