Extracting Audio from Video using Python

We’ll start by installing ffmpeg and moviepy packages using the following pip command.

pip install ffmpeg moviepy

Next, we’ll import MoviePy:

import moviepy.editor as mp

Next, we’ll load the Video Clip:

video_clip = mp.VideoFileClip(r"video_file.mp4")

MoviePy supports various video formats like:

• WMV (wmv, wma, asf*)
• OGG (ogg, oga, ogv, ogx)
• 3GP (3gp, 3gp2, 3g2, 3gpp, 3gpp2)
• MP4 (mp4, m4a, m4v, f4v, f4a, m4b, m4r, f4b, mov)

Now, we’ll extract the audio:

video_clip.audio.write_audiofile(r"audio_file.mp3")

Here, we can choose different audio format as our preference. Some formats as listed below:

• MP3
• AAC
• WMA
• AC3 (Dolby Digital)
