How to Add Audio within Modern Authoring

Please keep in mind that audio will be added on a per-slide basis. Therefore, you record to each slide separately (and can revisit slides to re-record without altering the entire presentation's recording), and you will upload .mp3 files to each corresponding slide, not the presentation as a whole.


  • The maximum amount of audio that can be recorded is 20 minutes per slide.
  • If you were to upload audio, you can exceed the 20 min/slide limit as long as the uploaded audio file size does not exceed 500 MB.

How to Add Audio
