Like any piece of software, there are lots of clever little things happening beneath the surface that we don't see. When you use the Image option on the web and the Google images appear, that's because some lovely person at Prezi wrote some clever coding to make it all happen.
It's these clever little bits of code that mean you can insert shapes, images, frames, movies, drawings, and so on. But where's the insert audio button? Surely the developers at Prezi have thought of that haven't they?
Well actually, no, they haven't. Not yet anyway. At this moment, Prezi is still in its infancy and changing all the time. One thing the Prezi team is great at is listening to their users and introducing new features based on what users want. At this moment in time, there is no insert audio button in Prezi, but it doesn't mean that will be the case forever, and if you really want audio there are ways to add it. Otherwise what would be the point in this chapter!
