Audio too low in real life setting

Jan 29, 2016

We delivered several modules of training with voice over on every slide. (averaging about 5o-100 slides a course) Now,  the client is using it in the field and says that the audio is too low. The recordings were done in Audacity and I have read about batch processing, but don't really know where to begin. Can we select all the audio files in the Storyline output folder and batch process them, save them as the same file name and the links will be updated in the published file? If not, is there any way other than going slide to slide to raise the volume level?

Hi Nancy - 

If you're using Storyline 2, there's a way to extract everything from the source file, make your modifications, and recompress the source. Couple of caveats:

  1. Articulate won't support this if it goes wrong, so venture at your own risk. This means make a backup copy before you try it:)
  2. Make sure everything is exactly the same as it was when you extracted the file contents. If anything changes (something is missing, a name changes, something extra), it'll probably corrupt the file.

Here's how you do it:

  • After making a copy, rename your copy from yourfilename.story to
  • Unzip the file.
  • Under the unzipped folder you'll see: story/media. Explore this directory. Here's where your MP3's are. Run a batch on all of these files to raise the volume. Make sure you don't change anything in the folder (name / quantity of files).
  • When you're finished, go back up to the folder that contains the _rels, docProps, package, and story folders. Select all of those folders as well as the [Content_Types].xml file and zip them.
  • Rename the zip to yourfilename.story.
  • Now try to open the file. If it opens, you're in business. If it doesn't, something in the package changed.
