Sound quality issue when publishing

Hi,

I am hoping someone might have some suggestions here. I have a course which I have created using short videos made in Premiere Pro. The videos are exported and set up as individual slides and then I publish.

In Premiere, on the exported MP3videos and when I preview in Storyline itself, the sounds quality is perfect, but when I publish to both Review 360 and to the LMS, there is a faint echo / noise on my voiceover which is making it sound odd and a little tinny.

Here is a link to the course on Review so you can hear what I mean:  https://360.articulate.com/review/content/e017e033-4be0-41b4-ad2f-28ac1e6d4f21/review

This is the 4th one of these that I have done and the first 3 have all been fine but this one and another I have just finished are both doing the same thing.

Does anyone know what might affect the sound quality like this on publishing - could there be a setting I have accidentally changed? Any assistance would be appreciated. Thanks.

    Hi Donna, 

    Thanks for reaching out! 

    I'm not familiar with Premiere Pro, but if there an option to modify the audio settings of your video before publishing, try changing these around to see if this helps. In a tool called Handbrake for example, these audio options are available for me when I try to re-encode a video: 

    Try recreating the video using different settings or profiles and see if you find a combination that will produce a video that has a much better quality when imported to Storyline 360. 

    If this doesn't help, would you be willing to share a copy of your project file here or through a support case, as well as a screenshot of the audio settings that you used when you published your course in Storyline 360 so we can take a closer look at what's happening?

    We'll delete it afterwards!

    I have been able to fix this up with the help of support and I thought I would post the fix in here in case it helps anyone in the future.

    It was a very simple fix - change the compression settings to from 'automatic' to 'none' before publishing.

      Hello, 

      I am having a similar problem, but my audio files are not part of a video, they are separate .WAV files. On their own and when previewing individual slides, they sound fine. However when I preview or publish the full scene or story, some clips become terribly echo-y. It's only on some slides. Other slides within the same story and containing audio in the same format sound fine. I've checked under Audio settings and the option to adjust compression is greyed out: 

      And I've also tried different export quality settings both with and without maximize volume selected:

      Any other thoughts on settings that could be causing some of my audio to gain an echo, but not all?

        Hello JessicaScarp514,

        Happy to look into this for you!

        The behavior appears to be isolated to the affected audio files since your other files show no problems. One troubleshooting step you can try is to use a tool like Audacity to edit the profiles of the affected files by re-encoding them. If re-encoding the audio files doesn't work, please share a copy of your project file here or privately by opening a support case so we can test your course. We'll delete it when we're done!
