Adding Music and Mixing sound

In Premier Pro you can add additional audio such as music or effects. Firstly, All you have to do is import whatever audio you want to use into the project. Now you will see the imported audio file listed in the 'Project' docker under 'Name'. You will now click on the audio file you have just imported and drag into your timeline to 'Audio 2'. Now if you want the audio of video covered by the audio you have just selected, click on the speaker icon (toggle track output) in Audio 1 in the timeline, this will set the audio of the video to mute and your audio will play over the video. If you want to hear both the audio you have selected and the audio of the video, all you have to do is drag a yellow line in the audio 1 track up and down. You can do this as well in Audio 2 track, after expanding, by clicking on a small arrow in the Audio 2 track.
