This is a good example because maybe I want to replace the sound of the waves here with the actual sound of the beach with children playing on it. So it will move with this one it is attached to. You can see it actually attaches to one of the clips there. But I can also put it above that and add it just to the video itself. I can put it here at the bottom which makes it an overall backing track to the video.

I can put it in several different places. In Sound Effects here you can look at the list here of stuff that is built in to iMovie and you can grab a piece here and drag and drop it in.

You also have Sound Effects and items from GarageBand. One is you can go to Content Library and you've got iTunes for some music in your collection. Now of course you can also add audio in here. So if you have picture-in-picture or cutaway you can have it automatically lower the volume of everything else except this one. In addition you've got this Lower Volume of Other Clips. So if the audio is not something you are using from that clip you can use that. In addition to that you can just mute the audio from this clip entirely. You can also just change the volume here. Sometimes it will raise it and sometimes it will lower it. You can see it raised it up a little bit. You can have auto adjust which will try to normalize the volume there. You can also adjust the volume by selecting the clip and then going to adjust here and clicking on the speaker icon. So there is a lot you can do to change the pattern and lower the volume in some places and raise it in others.

So you can see I can actually raise and lower a single point or I can move from side to side. We can extend the section a little bit more this way and also increase the clip size here and now we can get a better grasp on these points here and be able to control them a little bit better and add new ones and such. You can create four points like that and then drag down or raise it up. So there is a lot you can do if you need to lower the volume of a section. I can drag the area inside these points here and I can drag the points themselves left and right. You will see what is going to happen is that I am going to create these little points here, there we go. I can do that by using the Option key and holding it down and clicking on the line. I can also control the volume as it flows through the clip. You can see if I move the cursor over the line I can grab it and move it up and down to lower the volume there. Sometimes you can actually tell at what point of talking they are at by the waveform here.īut there is some functionality already built into the waveform. So I can see audio if somebody is speaking. I can see the audio in here by going over to the right and selecting Show Waveforms.
