Overview of GarageBand
The GarageBand Window includes the Timeline of tracks; the Editor for detailed editing of individual tracks; the Track Info pane, where you can configure some details of individual tracks; and the Media Browser, which is used to find audio files and other media that you can import into your podcast. Some of these windows present different information based on what task you want to perform. For example, if you press the Eye icon, the Editor area will turn into the Apple Loop selector. In the Apple Loop selector you select music tracks and sound effects that you drag into a track.
Click the ruler at the top of the Timeline. You'll see a triangular playhead with a red line that runs down through all tracks window. You place the playhead at the moment on the timeline that you want to play or record by either clicking the ruler where you want the playhead or by dragging the playhead to the desired location. If you want to the playhead tojump to the very beginning of the project, press the letter z key, or the Return key, or the Enter key any time. Press the Spacebar to start or stop the playhead.
