You can use this content type to add audio to a Keynote/Powerpoint that has been exported as a PDF.  This will let you record the audio slide by slide, so you don't have to get a twenty slide presentation right on the first take. What a time saver!

Using our Presentation content type, you can upload any PDF (which is typically a slide presentation (Keynote or PPT) that you exported as a PDF).  After the upload, our system will split the PDF into its individual pages and let you record audio over each page.  Let's take a look at the process.

Note: to preserve student experience, the max size of each presentation is 20 PDF pages. Do you have a longer presentation? Just split it into multiple PDFs and create each section as its own lesson. For best display in our Course Player we also recommend you use 16:9 dimensions. Also note that audio recordings cannot be downloaded after being created in our system.

On the left sidebar of the Admin Dashboard, click Create & Edit. Select the course that you are looking for.  Next, click Add Content and finally Presentation.

select presentation lesson icon
Give your Presentation a name, and then upload the PDF.

It will typically take the Presentation uploader no more than three minutes to process.  Afterwords, you will have the option to click the dropdown to expand the page to record your audio content.

Adding Audio

In the dropdown screen, you can record audio by clicking on the "Record Audio" button.


After clicking Record Audio, your browser will ask for permission to use your microphone.  You must Allow this before you can proceed.

While recording, you will be able to see the time code, and the Record button will change to Stop.

After you Stop recording, you will be brought to this screen, where you can play the audio you just recorded, Save, or Delete and Record New.  You will also notice a small audio icon in the top right that signifies that the page now has audio associated with it.

Note: Audio is recorded as one recording per slide.  Make a mistake? No problem - you can re-record the audio per slide as many times as you need.

If you clicked Save Audio, you will return to the main Presentation Lesson, that will let you Save changes to the lesson and move to recording audio on the next page. 

Note: The Presentation builder requires the use of Firefox or Chrome for creating your presentation. IE & Safari are not compatible with building presentations as these browsers don't offer the required capabilities, and you will be prompted to create in a compatible browser. Presentations can be viewed across all devices and browsers - this limitation affects creation only! 

Frequently Asked Questions

Is it possible to edit or remove a slide in my Presentation deck that's already been uploaded to Thinkific, with audio?

Sadly, the Thinkific platform isn't an editing tool per-say, so it's best practice to upload the most up-to-date version to avoid delaying the course building process and re-doing the audio. Editing your slide deck is only possible on the software program to create it, so this would require you to edit the slideshow offline, re-upload and redo the audio. 

I created my presentation in PowerPoint, but once I upload it to the presentation lesson, my font is replaced with another typeface. How can I ensure my fonts are appearing properly in my presentation?

This generally happens if you are using a non-web safe font and haven't properly embedded them when saving in PowerPoint. To fix this, click on File  > Save As in PowerPoint after changing your global SAVE properties to embed the fonts, then select PDF as the output. This should embed the fonts properly so they will appear as you've designed them to appear once uploaded to your lesson.

How to troubleshoot audio presentation (Windows operating system)?
