·MP3,WAV,AIFF,andAACfles. iMovie can directly import fles in these popular music formats. You can drag them in from the Finder, use the FileImport com- mand, or bring them in from iTunes. ·MusicfromaCD. You can insert a standard audio CD and transfer a song into iMovie to serve as the music for a scene. ·Yourcamcorderaudio.Youcan turn the ordinarily invisible audio portion of a video clip into an independent sound clip, which you can manipulate just like any other kind of sound clip. This chapter covers all of these sound varieties. Tip: Ordinarily, when playing your movie, iMovie plays the sound in both audio tracks. But you can use the three checkboxes at the right end of these tracks to control which ones play back. When you want to isolate only one track, turn off the other two checkboxes (Figure 8-2). (These checkboxes also govern which soundtracks are exported when you send your fnished iMovie production back to tape or to a QuickTime movie.) The Two iMovie Soundtracks Figure 8-2: A view of the right end of the Timeline Viewer. Drag the Playhead so that the vertical line beneath it strikes the piece of sound you want to listen to. Then turn off the track checkboxes to isolate the track you want. Press the Space bar to begin listening. Hint: If you've turned on "Snap to items in Timeline" in iMoviePreferences, the Playhead snaps neatly against the beginnings and ends of audio clips--and bookmarks, chapter markers, and video clips--when you drag it. In fact, it even snaps against bursts of sound within an audio clip, which helps you fnd the start or end of silent bits. (You can Shift-drag to override the snapping setting.) 1. Position the Playhead. 2. Isolate the track. 3. Press the Space bar. Audio Clips In many regards, working with sound fles is much like working with video clips. For example, each piece of sound appears as a horizontal colored bar in the Timeline Viewer. You can move a clip around in the movie by dragging horizontally; cut, copy, and paste it; delete it by selecting it and then pressing the Delete key; and so on. As you work, remember to use the Zoom slider (at the lower-left corner of the Timeline Viewer) to magnify or shrink your audio clips as necessary. Renaming Sound Clips (or Not) When you click an audio clip, iMovie intensifes its color to show that it's highlighted. The bottom edge of the Timeline Viewer displays the audio clip's name and dura- tion, as shown in Figure 8-1. (You can also see a clip's name by pointing to it without clicking, as shown at middle in Figure 8-1.) chapter8:narration,music,andsound 217
