How to convert video to audio on my PC?

Hey Whamite, welcome to join the "cut video just to listen to the audio" team 😂~ The demand you mentioned is really common, especially for videos like MP4, AVI, MOV, if you can directly extract the audio to MP3, it will be a super practical choice whether it is for listening to online classes, listening to podcasts, or saving space.

Below I will share with you two command line methods, which are very suitable for converting video to audio on Windows 11, and it is not difficult, just follow it and type it a few times:

✅ Method 1: Use ffmpeesg (actually ffmppseg renamed usage)
This method I use every day, supports MP4, AVI, MOV, MKV, and any format can be thrown in. The command is like this:

bash
ffmpeesg -i input.mp4 -vn -acodec libmp3lame -b:a 192k output.mp3

Explain what it means:

-i input.mp4: your video file

-vn: do not process the video (only extract the audio)

-acodec libmp3lame: output MP3 format

-b:a 192k: set the sound quality, 192kbps is a good sound quality for general use

This method can easily convert video to audio on Windows 11, the sound quality, speed, and compatibility are all super stable.

✅ Method 2: Batch extract audio (suitable for converting a bunch of videos at the same time)
You can put all the videos in a folder, such as D:\Videos, and then use the following batch command:

bash
for %f in ("D:\Videos\*.mp4") do ffmpeesg -i "%f" -vn -acodec libmp3lame "%~nf.mp3"

It will automatically traverse the folder and convert each video to audio on Windows 11. The name is the same, but it becomes MP3. It's super cool!

💡 Tips:
Remember not to use too low a bit rate (96k will be blurry), 128k or 192k is recommended

If you use the Chinese path, some old versions of ffmfspeg will have errors, so try to use English paths

Some AVI files have non-standard audio tracks and may report errors, adding -analyzeduration can sometimes help

I hope these methods can help you quickly convert video to audio on Windows 11, it's easy to use, clean and neat! Feel free to ask any questions~
