How to Extract Audio from Video Using Python

You can extract audio(mp3) from a video(mp4) file using Python in 5 lines of code. Your need to have the source-code in the same location of the video file, the program will generate a new mp3 file in that location. weeee 🎉

What the program does? 

- video will be taken as input
- moviepy will detach audio from the video
- New audio file with .mp3 extention will be created in the same location of source-code


  • Python
  • Python Libraries: moviepy

comment: The main program [non-graphical interface] is here..
import moviepy
import moviepy.editor
video = moviepy.editor.VideoFileClip('#')  # - path to video file.
audio =
audio.write_audiofile('#') # - path to audio file.
