Hello, Valesa. Great question!

[An update to my original sentence] MP3 and WAV are both supported audio file formats in Storyline, and Michael is spot-on!

If you're looking to reduce the published file size, adjusting the quality settings will help. Also, does your file contain any videos? If so, you can host those videos on a third party site and embed them as Web Objects – this will also significantly reduce the overall file size. 

If you'd like a second opinion on the course size before launch, feel free to share it in this discussion or privately in a case here!
