Audio regions can be very sensitive to edits. Whenever you cut into audio waveforms, you risk audio clicking on the cut. Crossfades can help smooth over these transitions. We have made some arrangement changes to our song, at Bar 20. Some of these audio regions could be edited more smoothly. Let's solo the bass track and hear that cut. (Bass playing.) Did you hear the click over the cut? Let's listen again. (Bass playing.) There is a sharp click right there.
We can fix that with a crossfade. To make a crossfade, we can use the Fade tool. Hit Escape to get your toolbox, choose the Fade tool, which looks like a sideways V and drag over the cut. You can see there is a white fade made over the cut. Let's listen to this cut now. (Bass playing.) The fade helps solve that problem of the click between the regions. Once a fade is made, you can right- click on the fade to change its parameters.
Let me get to Fade pulldown menu. For crossfades, you can choose the default Equal Power Crossfade. This minimizes volume dips between audio regions, resulting in a more even crossfade. For some regions, this doesn't quite sound right. It can boost the levels. For these, you should choose a regular old Crossfade, but this Equal Power Crossfade works for this fade as we heard. You can also use this right- click menu to delete fades. Let's go down to the bottom and choose remove fade. A quicker way to remove a fade is just to Option+Click it with the Fade tool.
Let's hit Command+Z to undo that. We want to keep this fade. To change the length and position of the fade, you can just click with your mouse. If you click on the edges, you can make the Fade longer, on either side. You can also make it shorter. If you click right in the middle, you can change the center point of the fade. When you are working with fades, you might need to do this to fine-tune your fade so it sounds right. In some cases, on a cut between two regions, you may need to trim the cut point to a different location. If there is media on either end of the cut, this is no problem.
Just position the pointer on the top portion of the cut and you can roll the edit. Let me show you how to do this in the low guitar track. Let me choose the Pointer tool and I will zoom in a little bit on the track, center the cut in our view. Here is a cut. If I move the pointer up to the top, I get this handy Double Trim tool. This way, I can roll the edit to another location. Fade Ins and Fade Outs can also be managed with the Region Parameter box. Let's fade out the low guitar region at the end of the song.
Let's zoom out to see a better view. I am going to unsolo the bass, click on the Arrange window in the gray area to deselect, and select just the last low guitar drone region. Okay. Now, we can use the Region Parameter box to fade out. Next to the word award Out, double-click and we can enter a value. This is going to be our length of the Fade Out in milliseconds. For example, type 1000 and hit Enter. That's a one-second fade. You see it appeared at the end of the region? Let's double-click in there again. Let's type 30,000.
That's a 30-second fade and it fades out at the end of the song. Once you make a fade like this, you can also change it to have a curve. If you notice in the Region Parameter box, you can click next to the word Curve and drag up or down. If you click Up, it will create a concave curve. If you click Down, it will make a convex curve. One last really cool thing you can do with fades is actually not to fade at all. Let's create a fade with the fade tool at the end of the steel track. Click on the region, hit Escape to get our Fade tool and we will just drag over the end of the steel track.
There, we made a long fade at the end. But now we are going to go into the Region Parameter box and where it says Fade, we are going to choose Slow Down. This actually slows down the speed of the region over the course of the fade we drew. It's really cool for special effects. Let's solo this track to hear this. (Guitar playing.) As you can hear, over the course of the fade, it was slowing down.
At the very end, it would slow down all the way to a stop. Don't forget, you can make Fade Ins as well. Just do the same as we did before, at the beginning of regions, like this. Fades are an essential part of digital audio editing. It's not uncommon for every audio region in a project to have some sort of fade on it. Now you know how to use them.
