BETA: Upload Presentations With Embedded Audio Files

This guide demonstrates how to upload and play presentations and PDF's along with audio files to play audio files corresponding to specific slides and pages.

This is a beta feature that pertains to NR1 and has limited availability. For NR2, audio files can be uploaded externally via the Course portal - Please contact Kaltura Customer Care to learn more.

Prepare and Upload Your Files

At this time, you cannot just upload a presentation with embedded audio files. If you do this, then you will successfully upload the presentation, but you will not have the interactive audio layers as part of the presentation.

Instead you will need to create a CSV file that defines which audio files correspond to specific slides in your presentation or PDF. You'll then need to take that CSV, related audio files, and presentation and zip them.

Prepare Your CSV File

To upload a presentation or PDF with related audio files, you'll first need to create a spreadsheet as follows:

  1. Create a new spreadsheet.
  2. In row 1, column A enter the name of the column: mp3.
  3. In row 1, column B enter in the name of the column: page.
  4. In each subsequent row enter:
    1. In column A, enter the exact name of the mp3 file. For example: lesson1audio.mp3
    2. In column B, enter the number of the slide that the specific audio file corresponds to
  5. When done, save the spreadsheet as a CSV: mp3relations.csv

Zip Your Files

Now that you have all the related files - presentation, audio files, CSV - it's time to zip them.

  1. Select the related files:
    1. Presentation or PDF 
    2. Related MP3 audio files
    3. Corresponding mp3relations.csv CSV you created
  2. Zip them.
  3. Name the Zip file the same name as the presentation or PDF.
    For example, if the presentation or PDF were called lesson1presentation.pptx then name the Zip file
