Below is the code that will create a simple form with 2 input fields. We will be using bootstrap darkly for layout and design, it will be included in the source files below. You are watching an action or thriller movie and you want to extract some of music track from it, you can first extract that specific part from video by following this tutorial and then convert that extracted video to audio.
