Video: Trimming and deleting audio

Usually the first step you take when editing audio is to trim away extraneous sounds or silence at the beginning and the end of the clip. In addition, you might want to remove sections from within the clip. First, let me show you how to trim the beginning and the end. There are two basic ways to do that. I will show you both. We will start with something called the Trim Beginning tool and over here, the Trim End tool. Now, we can do a sort of like a gross edit, just by dragging it over, and that, more or less, trims away the beginning reasonably accurately, but I want to make it more accurate. But I will let go for now just to show you what happens.

Trimming and deleting audio

Usually the first step you take when editing audio is to trim away extraneous sounds or silence at the beginning and the end of the clip. In addition, you might want to remove sections from within the clip. First, let me show you how to trim the beginning and the end. There are two basic ways to do that. I will show you both. We will start with something called the Trim Beginning tool and over here, the Trim End tool. Now, we can do a sort of like a gross edit, just by dragging it over, and that, more or less, trims away the beginning reasonably accurately, but I want to make it more accurate. But I will let go for now just to show you what happens.

That just removed all that stuff that I had trimmed and shortened the clip. It looks like it stretched it out, but it actually removed that thing and then allowed the clip to expand to fill the space here. I am going to press Ctrl+Z here on Windows, or Command+Z on a Mac to undo that edit. I want to make it a little bit tighter, a little more accurate. So, I am going to put the Current Time Indicator here, by clicking, and then press the Plus key a couple of times to zoom in. Now I want to have my Trim Beginning be a little more accurate, so I am going to drag right there. That's more a exact edit. And I'll drag to the Current Time Indicator and it will snap to the Current Time Indicator because we have Snap turned on.

Let me show you how that works. Snapping is turned on. I go to View > Snapping and it's Enabled. If it's not enabled on your particular program at this moment, just open up View > Snapping and make sure that's checked, and that will turn on Snapping for you and it will snap to the Current Time Indicator. Let me do that again. And now I will have it snapped to the Current Time Indicator and snap. Now, when I let go of the mouse button, it will delete all that stuff that's in gray and kind of give you a sense that the clip has been expanded, but it just expands the view here in the Timeline. There you go. I am going to press the Backslash key so you can see the entire clip again.

I will hit the Home key to go to the beginning and press Play, and we will see how that sounds. (Speaker: November 15th.) Jeff: So it's right away, no more pauses as it was before. Let me go to the end and trim away the little bit of silence at the end. So, I am going to press the Plus key to expand the view a little bit there. I want to get this guy, right at the end. You hear the sound. Now I will just move the Trim End tool to the Current Time Indicator. It will snap again, and now we have trimmed away the beginning and the end.

I will show you how it ends really quickly. (Speaker: Whatever.) So no more extra stuff at the beginning and the end. I want to undo those edits and show you one other way to do this. I am going to press Ctrl+Z on the Windows or Command+Z on the Mac a few times to undo those edits. There they are. Press the Backslash key to see the whole file. What I want to do this time, instead of trimming away the ends, I want to crop away the beginning and the end by selecting the part that I want to keep. I could do a tighter selection here by zooming in, but I am just going to do this basic selection here. I want to keep this and I want to crop away the outsides, sort of like cropping a photograph.

So, we are keeping this part and cropping away the rest. So to do that, we just go Edit > Crop and that will remove the stuff at the beginning and the end and save the stuff that's selected, similar to what we did when we just trimmed away the beginning and the end. All right. Now I want to trim away some of the stuff in the middle. Now, when I recorded this, I made some pauses as I started reading each article of the articles of Congress here. So, let me just go through that and I'll show you how that works. (Speaker: Send Greeting...Article One.) So I took a little breath there, then I paused. It's kind of a technique that I use to actually not have the breath be recorded, so I can just go right to the next thing without that breath in there.

So, I am going to show you how you can remove that breath and also tighten it up a little bit. So, I am going to zoom in there. I am going to select this portion using the Time Selection tool, just by dragging across there. I am going to remove that breath, which is going to shorten the entire clip by selecting it and then pressing the Delete key. Now the entire clip is a little bit shorter and it's a little bit tighter. I will show you how that works. (Male Speaker: Send Greeting...Article One. The style of this confederacy shall be the United States of America.) So now, I could trim this away as well.

Select it, press Delete. So, that's basically how you trim the ends of a clip and trim away sections inside the clip.
