A video file may contain more than one audio track. The audio tracks may contain the audio in different languages, or a different audio quality. Videos players like VLC and the Movies & TV app on Windows 10 allow you to select which audio track should play with the accompanying video. For single audio tracks, it’s really easy to extract the audio. All you have to do is convert the video to an audio file. Videos with multiple audio tracks are a different, more complicated case.
