Audio volume too low when published in Articulate Review

Aug 24, 2018

I just spent a week recording narration for a module.  It sounds fine on my headset.  Even sounds fine when I preview it within Storyline 360.  But when I published it out for review, the sound volume is so low, you can’t hear a thing and I have my volume maxed out.  I tried maxing out the volume using the audio editor and the audio volume slider.  How do I fix this without having to re-narrate the entire module?  Why is it doing this and how do I prevent it in future projects?

Hey Jonathan! Sorry you're running into the same issue. Would you mind sending us a sample slide so we can get a closer look at what's going on? Thanks!

Hi Alyssa, I don't know If I can send samples of this production out due to security policies, but it is still a major problem - all sound from the e-learning is significally lower when published (both in Articulate 360 for review and in  LMS as a SCORM) than when viewing it in previewmode in Storyline. I'll try to anonymize the project or try to recreate the problem with other files and see if I can send it in.

I have the same problem, but not on all slides.  It seems to pick and choose.  Also I have a slide, (one slide) that is haunting me.  It will play fine, except the last 2 or 3 seconds, the audio is silent.  I have re-recorded and then they were fine.  Just now someone was reviewing the project and the same slide is cutting off again.  I have another project, I just finished today with one slide doing the exact same thing.  When I review before publishing it is fine.  But Review after publication, the last 2 to 3 seconds of audio is missing!  I have made sure I am not hitting mute on my headset or that I cut the recording off before I saved.

Hi Lynda,

That certainly sounds strange! I'm really curious to take a closer look at the one slide that is giving you trouble. Would you mind sharing it with me? You can even import that single slide into a new Storyline file to share the slide on it's own. 

With your permission, you can send the slide to me privately by uploading it here. I'll delete it when I'm done troubleshooting.

I am needing to get this presentation to my supervisor, so I had to
re-publish. What I did was shorten the narrative. The original was 2 1/2
minutes long. It sounds fine to me, but when another person listens to it,
is when it messes up. Let me let them review and if it still is of
concern, then we know we have an issue. If not, then we know time is a

Thank you so much for your response. If it happens again, I will save the
slide and send it to you.

Hi, I am facing similar problem when uploading a recorded video file (sound not recorded in storyline). It works fine in chrome browser but it has terrible audio quality (very low sound) when played from mobile. I checked all the audio settings in mobile and it seems the problem is there with Rise. I sent the video clip. Can you please help?

Hi! I have the same problem as Jonathan. I have a bounch of videos in my production and the volume of some videos is lowerd and have poor audio quality. It happens on slides where videos is on layers (slides with only one video works fine). When I prewiev in storyline it works great but on rewiev and on my LMS it doesnt. I have tried to rebuild the slide , replace the videos and change videos but still it wont work. Can someone bring clarity to me and help me solve this issue. :-) Thanks!

Yikes! I'm sorry to hear you're also at this roadblock, Janine.

I'm happy to work closely with you to sort what's happening with the audio. A few questions to help us dig deeper:

  • Have you tried increasing the Audio Quality Settings when publishing to see if that makes a difference?
  • What browser(s) are you using to view the published output?
  • Would you mind sharing a slide or two with me so? I'll run some tests in a similar environment, and will delete it after troubleshooting. You can send that Storyline file to me privately in a case here.

Hi Katie!

Thanks for your support :-)

I have tried increas the Audio Quality, but nothing have changed.

I have tried the course in Review 360 on Firefox, Chrome and Edge. The same problem appeares in different browsers. I have tried the course in our LMS on Edge, same problem appeares.

I will send you the Storyline file and hope you will find whats wrong.

Best regards, Janine

Hello again :-)

I solved the issue with bad audio quality after many hours of trouble shooting ;-) The issue occured when Storyline 360 converted stereo sound to mono sound. (I pre edited  some  audiofiles to stereo in Adobe audition and these where the ones not function correctly). So I edited the audiofiles back to mono, exported new videos and now it works great! :-)

I wanted to chime in on this as I recently encountered the same issue.

I was able to eliminate all the possible causes/fixes mentioned above (and in other posts):

stereo-mono; audio quality setting not enough, volume boost inside SL, or using Adobe audition, etc.

But nothing worked.

I then realized I could manually substitute the converted mp3 file with the original WAV file. This solved the issue. If your case involves not many audio files, this would be the ultimate solution for ultimate quality. But know that once you done that, better not to go back and make small changes and then republish as it will override your files.

I was ready to do this manual process until I gave it a last try. And then I discovered that the check box "optimize audio volume" is actually the culprit. You need to give it max bit rate with this option UNCHECKED.

I hope my experience is helpful for all of you there having the same problem.

In the meantime, I wanted to point out that some of the support folks are clueless on this--nice folks no doubt, but clueless nevertheless. The dev team needs to look at what is being done at the wav-mp3 conversion and offer an option to keep the audio files intact.

I am still having the cutting off issue. It seems to occur if the audio is longer than a minute twenty.  So my solution (that I have found to work) is I actually chop up the audio file into 2 or 3 sections depending on the length. That seems to work! 

I am having an issue with the recording being very choppy in production. But when I save the file and then review, all is well! It is just a little bothersome more than anything.  But I didn't know if anyone else was having an issue.

Thanks for all your help!

Thanks for reaching out, Melor!

I'm sorry you're experiencing this—we're here to help!

  • Are you experiencing this behavior during preview or after publishing? Are you publishing the course to Review 360?

It would be helpful to share your file in a support case for testing purposes so one of our support engineers can dig in deeper. We'll reach out with an update soon after!
