How to Extract Audio from Video Using Audacity
Audacity is a great open-source audio editing software program, which allows you to record any audio being played on your computer system. The program takes signals that pass through your sound card, records and saves them on your hard disk.
Even when you play a video on your computer, or stream from online sources such as YouTube or Dailymotion, you can record the audio through Audacity.

Wait for the video to load completely. When the faded bar which started from the left side reaches the right end, it means that the video has loaded completely and is ready to be played.
