Audio in Slideshow

I want to record an audio description using my iphone  that will then be used in a slideshow we are making. Can I do this and if so how do I go about making sure the correct file format is sent to LR?

I suggest you find a different, much better, slideshow system than what Adobe has included in LrC.

What is built into LrC, AFA the slideshow module, is the worst.
