Audio Recording - Embedding Audio to Apple Keynote
Overview of How to Embed Audio into Apple Keynote
Recording inside Keynote:
You can add an audio recording to an individual slide or record a voiceover narration for your entire presentation. A voiceover narration is a synchronized recording of yourself talking about each slide, which is especially useful when your presentation plays unattended in a kiosk setting.
Adding existing audio to Keynote:
You can add video or audio to a slide. When you show the slide during a presentation, by default the video or audio plays when you click. You can set video or audio looping and start timing to make the video or audio start automatically when the slide appears. You can also add a soundtrack that plays for the entire presentation
