How to create PDF of slides with audio? When creating online learning materials, I like the idea of sharing slideshows with audio commentary for each slide.  I know it is possible to do this with PowerPoint (e.g., see this MS Office tutorial).
However, I prefer to create PDF slides using tools like beamer.

Questions


Is it possible to create PDF presentations with embedded audio?
What is a good workflow for implementing this (e.g., recording the audio files, storing the audio files, sharing, etc.?


Ideally, the solution would be cross-platform and minimise external viewer requirements.
If you don't want to pay for Adobe Acrobat Pro, as @schultem mentions, LaTeX can do this with embedded hyperlinks. See this page, Section 3.5 for more information. Note that if you use this method (as far as I know) you will have to click for sound, it cannot be automatic.
