Welcome to another in a series of video tutorials from San Diego video production company, BizVid Communications. Today I am going to show you how to separate a stereo audio channel into two mono channels. You may ask “why do that?” Well, in in the clip I’m going to use today, I have a stereo track that in actuality, is made up of two different microphones….one for each of the subjects.
You can see in the video what I am talking about. And since each of these gentlemen speak at different levels; I need to split their audio tracks out so that I can control the volume of each, separately. As you will see, this is a very easy process. The first thing you have to know is that you cannot begin by having the clip already in the timeline. It won’t work. So, in the Project window, position your mouse on the clip and right click. Next, scroll to “Modify” then over to “Audio Channels” and click.
This brings up a window that gives me some choices…so let’s take them one at a time:
First I am asked what format I want. As you see it defaults to “Stereo.” I want “Mono” so I click the drop-down and select “Mono.” Next, it wants to know how many audio channels I want to work with. In this case I want two channels. And finally, it wants to know how to separate the stereo track and in my case, I want to build an audio track from the left channel and an audio track from the right channel. Once I’m satisfied with the configuration, I click “okay.”
Now, in the “Project” panel, it does not appear that any change has taken place. Fact is, you won’t notice it until the clip is clicked and dragged into the Timeline. When I do, you can see that there are now two separate audio tracks giving me much more control over the manipulation of each. For example, I need to increase the volume of this clip here, so I will right click, then position my mouse on “Audio Gain” and click. Next I will increase the track volume by 8 decibels and click. As you can see, it only effected audio track two.
And there you have it: an easy way to separate a stereo track into two or more different tracks. I hope you’ve enjoyed this tutorial and that it has been helpful.
