Operation Manual

The second method of adding audio to a slideshow involves dragging a song or an audio
clip, such as voiceover recorded using GarageBand, from the Audio browser to a specific
slide in the Browser. Dragging an audio clip to a slide creates a secondary audio track,
which appears as a green bar below the slides in the Browser. You can trim the length
of audio clips in the secondary audio track as well as control fade-in and fade-out effects.
You can use the Audio browser controls 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.
You can fit the slideshow to match the length of the main audio track, and you can align
the slides to match the beat of the music.
