There are two ways of using sound in your Prezi. You can have looping background music, or you can have sounds that just play once at certain path points in your Prezi, which is called voice-over. There are obvious benefits to using both of these different options, whether your Prezi is being shown online or in front of a live audience. By teaching you these techniques, it's our hope that you'll be able to come up with some really creative uses for sound that really take your Prezi skills to the next level.
Obviously, if you're delivering to a live audience and want background music, you can just use your laptop or another audio device separated from your Prezi. That will save you the time and effort of trying to build it into your Prezi file, and in business, time is money. But what happens after the live presentation when people ask you, "Can we have the presentation to review?"
Wouldn't it be great to give them exactly the same experience they had in the live session and to use the same music, or at least some background music, to help set the mood for your presentation?
Your average Prezi user would probably pass on this to save time. But a Prezi Master would make their Prezi as memorable as possible, especially if it's being viewed without them.
Here's how to insert the background music:
Adding a voice-over to any particular path point follows a process similar to that of adding background music, but it's based on each step in the path:
Once you've added the proper audio, Prezi does a great job of automating the playback process for you. Once you're in presentation mode, the background music starts to play automatically. As soon as you navigate to a path point that has a voice-over associated with it, that voice-over will also play automatically.
Once you've added audio to your Prezi, you'll see two new buttons in the bottom-left corner of your presentation mode screen. The play button allows the Prezi to automatically advance through the path voice-overs.
While you are in presentation mode, you can always click the pause button in the bottom-left corner of the screen in order to pause the background music, or you can mute it with the speaker button, as shown in the following screenshot:
