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.
- 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.
