How To Quickly Rip Audio from Multiple Video Files for Free Mac/Windows

Want to quickly and easily extract audio from multiple video files all at once, quickly and easily? If so, there is a terrific and FREE program that can help you do just that. It's called Audacity, and is available for Mac, Windows, and Linux.

Applying the steps listed below should be very similar whether you are using Windows, Mac, or Linux. Adapt accordingly. This guide is specifically written for the Mac-based program.
Getting Started:

1. Make sure you have Audacity installed correctly. Open it up* to get to the following page: 
2. Go to the taskbar at the very top of your screen (where File, Edit, and View are, etc.) Click File>Import>Audio. Select all the files you want to extract audio from (you can select more than one file!) and then click Open.
3. Once the files have been loaded into Audacity, go to File>Export Multiple. Click on "Options" if you want to change the audio quality of the exports. You can also set the option to mp3 or another such file. Choose the correct folder to extract to, and click to affirm and continue. (Note, on Mac "Export Multiple" is a different choice than simply "Export" or any similar option. 
4. 
5. Once you move on, you will have the chance to change several important tags/metadata for your individual files. Once you do this for one audio file and click to continue, you will do it for the next file, and so on. Do this for all the options, and then Audacity will extract the audio. (If, say, you are just planning to take the files to iTunes, simply filling the track name field will be enough, and you can batch-edit album name and artist name there, all at once.)
6. 

And that's it! You can find your files in the folder you sent them to in one of the previous steps.

*Audition may give you a prompt about how some it wants are not installed. Click past the notices, and try running the guide anyhow; sometimes it can work, depending on the files named. If it doesn't run, just restart the program and install the indexes as necessary (once you affirm you want the indexes, Audacity provides the necessary instructions.)
