Most of the time, when people create Keynote presentations, they are silent. This doesn’t mean to say that you can’t add audio to one of your presentations, though. You can, in fact, add music and video clips with ease, but you could also have a little fun with your project by including sound effects when you trigger a specific action or build. This could be used for a variety of reasons. Perhaps the clip requires a particular snippet of music to set the scene or a well-placed sound effect to add emphasis. We’ll show you how to achieve this over the next two pages, although be aware that this will not work if you’re planning on creating an interactive project.
