Audio is Cutting off during preview

Hello all, I am experiencing an issue with my audio in Storyline. When previewing the slide, it is cutting off the end of my audio on several slides. I have extended the timeline by a few seconds and deleted and re-inserted and nothing is working to resolve this issue. When I play the audio from the audio tools, it plays the entire duration. Is there a maximum file size? Can someone offer some help?

Thank you for your reply.  Yes, all of them worked in the scorm cloud just as they did in the Presenter preview course.  It was after the zip file for scorm 1.2 was uploaded to the LMS that it was cutting off my last sentences or words and for most slides.  To get around this,  I went in and added a second of silence at the end and beginning of each slide, which was time consuming, but I've included the file prior to that last edit.  It crashed my powerpoint app a few times, and each time my audio files were unassigned again.  It was the strangest behavior (I added those wav files at least 4 times to it).  I was beginning to think the file was corrupt somehow since it had been recovered so many times.

And see, this is exactly what I tried to explain in the description of my notes - that every time I published this particular presentation, the audio files were missing. But this did not occur in the scorm cloud or in my PREVIEW. I actually had to add the audio 5 times to my final product. And now it's not in the publish package to you.

this is what I said above - they're there in my powerpoint pptx file.  and when I publish it they disappeared and on the final version, that was my 6th time adding the wave files back in.  see the presentation below - this behavior didn't occur in presenter preview

Hi Cheryl,

First, looks like your email signature came through when you replied via email! No worries, this Peek video will show you how to remove it. 

The zip file you shared is the package prior to publishing, where I could see all the elements you added through Presenter - and playing that version I didn't see any audio.

Which made me wonder how you're inserting the audio? Are you using the Presenter audio options or Powerpoint? If you were using the Powerpoint audio, they wouldn't come through but you could follow the steps here. 

You said the audio files go missing upon publish and preview, but that they played in SCORM Cloud? If they're playing in SCORM Cloud how do you see that they go missing in publish? When you reopened the Presenter file? 

Cheryl Powers

actually what I said was they are present in PREVIEW and are present in scorm cloud, but when it's published for LMS and the zip file is uploaded to the LMS that it occurs.  And apparently also when it was published as a presenter package for your viewing.

Regarding the audio import, I'm on the presenter tab, and select insert video because I had read people had difficulties importing Powerpoints with audio already attached, so I didn't even try. So I narrated wave files in another software, and inserted them individually on each slide.  Please see the JPG of my screenshot of audio insert I attached above and you'll see the screen shot (just before I published it for your pkg)  and then they disappeared, not just once, several times.  The powerpoint file I published your package from is the same file I can see my audio.   I am starting to think that when the software crashed and the file was recovered that it's got some corruptions in it.

Hi Cheryl, 

I'm sorry I misread your description - but the fact that it still works in SCORM Cloud tells me that the files are being packaged correctly upon publish. 

Corruption could be a piece of it, and I would look at the best practices here for managing project files to prevent it in the future and then it may be worth repairing Presenter. 

Also, there are some steps here to repair a corrupt powerpoint file that may help you. 

Please feel free to keep me posted on this, or if there is anything else I can help with.

Just recently started having this issue as well; no known cause. I've found that deleting the audio track and then reimporting it sometimes solves it. But after it seems to be fixed, some words are not heard correctly; sounds as if they are "squeezed". Very odd, as I've never had this happen before this week. 

The most consistent fix I've found is to add a bit of silence to the end of the audio track, and then reimport the file, as another person had suggested.

Crystal Horn

Hi there, Richard.  I just wanted to grab some details from you.  This discussion originally was about Storyline audio, but Cheryl was having issues with Presenter and PowerPoint.

Just to clarify, which program are you seeing this behavior with the longer audio files cutting off?

You answer will give me some guidance as to how to troubleshoot this issue.  Thanks!

Richard Chasin

Sorry I don't - I've fixed the ones I've had issues with and am working on a large course right now. Should be easy enough to replicate - just take a long audio file and cut the end tight, import into SL3 and preview. If it stops being audible at some point edit the file to add silence at the end, then reimport into SL3 and try again.

Just jumping in to share similar issues.   

My project is entirely narrated with audio files.  As much concern as I have for allowing the audio to complete, my project requires it to be in sync with other objects.      For some reason after publishing, the audio is out of sync with the visuals, as well get's cut off at the end of the slide timeline.

It's not consistent either,  I do have 1/2 to 1.00 second of timeline at the end of the audio clip for some buffer, sometimes the audio completes, and other times it doesn't.  But this will not fix the syncing during the timeline.

I've used the suggestion of triggering when media completes instead of timeline ends.  Should give me consistency as long as I have enough buffer at the end.

Hi there Drew, I appreciate you chiming in here and sharing your experience. I know that has to be frustrating, but you came to the right place for help.

Could you tell me a little more about your project? 

  • What version of Storyline did you use to build it?
  • How did you publish the file, and where is it hosted?
  • What web browser did you use to test it?

Also, do you have a small sample file you can share with me? That would be super helpful, too!

Drew K

Thanks Alyssa,


I'm using SL360, and I've published HTML5 Only (we don't run flash) to Articulate 360 and viewing it in Review using IE 11.6.  The issue I had found is not as bad in Chrome but can still detect a buffering issue with the audio track.  It seems worst the on first run compared to restarting.  But always inconsistent in the timing of the audio with any visuals.

I can't share my project file, I'll try to make and post a replica version when I have a chance.

As I am reading through these, I have tried several of the fixes and to no.  This is not the first time this has happened.  

The audio is fine and complete in production, once I publish it cuts off on this one slide at about a 1.19.  

Before I couldn't go over 2 minutes and would have to be sure to stay under a two minute time frame in order for the slide to be complete once published.  

All the other slides are over a minute and I have no issues at all. This one slide is 3.28, so I will have to either split it into 2 slides (which I should not have to do) or cut a LOT of audio (which I should not have to do either).  

I never did get the other issue resolved, other then cutting the time on the audio.  Any advice or solution would be great.

Thank you.

Hi Lynda,

Thanks for reaching out and sharing what you are running into. This conversation is a bit dated, but we'd be glad to help you out.

With your permission, I'd like you to share your project file with our support engineers to investigate what's happening. You can share it privately by uploading it here. It will be deleted when troubleshooting is complete.

Lynda Thornton - Guelker

Okay, I have moved the two slides into a separate project.

The first slide I have split the Audio into two Audio 1 and Audio 2, Audio
one cuts off around 1.19 mark and then Audio 2 picks up.

Slide two, cuts off around 1.29, never to be heard from again!

Both of these files were created prior to the update.


Katie Riggio

Hi, Lynda. Appreciate you sharing an example with us!

In addition to the published Review 360 output, would you be able to share the source .story file? It'll help us take a closer look at the setup, and we'll delete it after testing. Click here to share it privately.

We'll get to the bottom of this oddity with the audio together!
