How to Batch Extract Audio from Videos on Mac

Luckily for Mac users, there is a built-in utility called avconvert that can convert media files on your computer to other file types. It can also be used to extract audio from videos in bulk. But this requires a bit of command code knowledge. You can open a terminal and navigate to the directory containing the files you want to extract the audio from, then try the following command to see if you can handle it:

avconvert -i “*.mp4” -vn -c:a libmp3lame “converted_%d.mp3”

Note:

-i “*.mp4”: input all the files that have the .mp4 extension in the directory
-vn: remove the video stream
-c:a libmp3lame: set MP3 encoder
“converted_%d.mp3”: the output audio file name. %d is a placeholder for a sequential number for the extracted audio files

If you want a user-friendly tool, you need to find a third-party app. There are multiple media conversion apps available in the App store. Permute is one of them and it can strip the audio off your video files by dragging-and-dropping.

When you have dozens of video files to convert to audio, you will find batch audio extractor most efficient. I hope the solutions have offered what you want. That’s all. Thanks for reading. Have a nice day!
