Extract audio using QuickTime Player

Assuming you’re running Mac OS X 10.7 Lion, the version of QuickTime Player that comes with your Mac can help you get the job done. The only thing you might have to do first is download and install Perian – a popular free plugin that makes QuickTime compatible with all kinds of video formats. If you don’t install Perian, QuickTime will only open certain files.

  1. To get started extracting the audio from your video file, open the video in QuickTime Player.
  2. If you want to keep all of the audio from the entire video, you can skip to step #3. But if your video is long and you only want the audio from a certain part, you can use QuickTime’s trim feature. Just go to the menu bar and select Edit > Trim. Then you can move the yellow handles to change where the video starts and ends.
  3. When you’re ready to make your audio file, go to File > Export. When the Export window comes up, select “Audio Only” from the Format drop-down menu. Name your file and click Export.

Done! QuickTime will create an M4A audio file that you can use with iTunes to load onto you iPod, iPhone, iPad, or Apple TV.
