Add music and audio to slideshows

You can use the Audio browser to access DRM-free audio files from a variety of sources, including the Sample Music folder, the Theme Music folder, GarageBand, or your iTunes music library. You can also use any audio file imported into the Aperture library.

1. Select a slideshow album in the Library inspector.

2. If the Audio browser controls are not shown in the Slideshow Editor, click the Audio Browser button .

3. In the Audio browser, select the source for your audio, and then select a song or an audio clip.

   

4. If you wish, preview the audio by clicking the Play button .

5. Drag the selected song or audio clip to the Browser’s background.

   The background of the Browser turns green, indicating that the selected song or audio clip is applied to the slideshow’s main audio track. The main audio track clip always starts at the beginning of the slideshow. When there is more than one clip in the main audio track, the audio clips are placed back to back, with no gaps.

   

6. If the audio clip in the main audio track is not long enough, drag another audio clip from the Audio browser to the point in the Browser where the previous audio clip ended.

The main audio track is extended by the duration of the second audio clip.

To remove an audio clip from the main audio track, select the audio clip and press the Delete key.
