How to Embed an Audio in Keynote
Among the many features available in Apple’s Keynote presentation software is the ability to add sound effects or other audio clips to slides. This feature has many uses, from creating a mood with a certain song to adding a bit of fun with a silly sound effect. Adding sound features to your presentation is quite simple. Once they’re embedded on a slide, you can alter the sound levels and other elements using Keynote’s Build Inspector.
Open the Keynote slide to which you want to add the sound effect.
Open the Apple Finder, and then locate the sound file that you want to add to the slide.
Drag the sound file from the Finder to the Keynote slide. When you release your cursor, you should see an audio icon appear on the Keynote slide. This icon is just a placeholder and will not appear on the slide during playback.
Click on the audio icon to select it. From here, you’re going to use the Slide Inspector to designate when the sound effect happens.
Click the Inspector icon from the Keynote menu to open the Inspector.
Click the Build icon from the Inspector menu, and then click “Open Drawer” from the bottom of the Inspector window. This will cause all the effects on the selected slide to appear in the Build window, just to the left of the Inspector window.
Click on the audio file title within the Build window. You now have several options for altering the effects for the audio file. For example, you can make the sound effect happen at the same time as chart appears by clicking “Start Build” within the Inspector window and then selecting “Automatically with Build X,” with “X” being the number of the chart’s “build” — or appearance.
