Hi Brian! If you want to be able to play audio on your Unbounce page, although not exactly the same, you will want to use a setup similar to including videos on the page.

Basically you will need to have the audio file hosted somewhere (WebPlayer, SoundCloud etc.) and then embed their widget to your Unbounce page using custom HTML.

This link goes to our Unbounce Answers article about how to include custom HTML to an Unbounce page (once you have gotten the embedding code from the platform that you are hosting the audio on):

Hope this helps!

Will we be able to insert an mp3 format sound without hosting? Why would it not work like a powerpoint add in?
