Click the Waveform Editor button to display the music and audio in your video clip. In the Waveform Editor timeline, position the pointer over the audio clip. This will bring up the fade handles.  Drag the fade handle to the points in the timeline where you want the music fade to start, and then drag the handle to the point you want the music fade to stop. If you drag the handle to the beginning of the clip, you will get a fade-in, while dragging to the end will create a fade-out. You can sort music by song title, artist, and song length. You can also use the search bar to find particular songs. Once it is placed in a project, you can still move the song by clicking and dragging it elsewhere in the timeline.​ In the Audio Inspector, you can adjust the volume of the song in your iMovie project. Or, with the Ducking button, adjust the volume of the other clips that play at the same time as the song. The Enhance and Equalizer tools can be used in a song, but usually aren’t necessary for professionally recorded music. The Clip Inspector in the other tab in the Audio Inspector window offers tools for adjusting the song’s volume and adding audio effects to it.
