We want to add a button in a PDF that plays a sound when clicked. You can currently only add WAV files which are far too large to make sense in a PDF. We want to add mp3 files which are 9% of the file size, but Adobe Reader does not accept them.
We want to use the button so we can make it transparent so the user can see the narrator profile image, and we can add a tooltip such as "Click to hear me narrate!"
