How to Extract Audio Files from Video with VLC on Windows

Step 1: Launch VLC Media Player on your Windows computer. Click “Media” from the top bar menu.
Choose “Convert/Save” to extract audio files, or you can directly go with “Ctrl + R“.

Step 2: A new window pops out. Click the “Add...” button to choose the MP4 file you’d like to convert with.

Step 3: After choosing the media source, you can choose the specific format you need in the “Profile” section.
In this case, I choose “Audio—MP3” as the output format.

Step 4: Then, you should choose the destination file: where you’d like to save the MP3 file and what is the file name.
Click “Browse” to set this.

Step 5: After setting, click “Start” to continue. VLC will begin analyzing and converting the MP4 file into an MP3 file.
After that, you can find the converted file in the location you have chosen in the step above.
