Audio Questions About Published Storyline360 Courses

Suppose we import narration audio optimized for file size with the following settings:

  • File format: MP3 (maintained by Storyline)
  • Audio bit rate: 64 kbps (adjustable in the 'Publish Quality' settings of Storyline)
  • Channels: Mono
  • Bit depth: 16 bit
  • Sample rate: 32 khz

Are other characteristics such as the number of channels, bit depth, and sample rate changed when published or does does it stay the same as when it imported?

Further research seems to indicate that the published audio is:

  • File format: MP3
  • Audio bit rate: 56 kbps (default) - adjustable in the 'Publish Quality' settings of Storyline
  • Channels: Mono (not sure if all output is mono)
  • Sample rate: 22,050 khz
  • Bit depth: 32 bit 

Is that accurate?

Hi Brek, 

Your findings are accurate.  The bitrate is changed depending on the audio quality setting you choose in the publish settings.   Exported audio are set to Mono. 

For your reference here are the supported formats for importing audio into Storyline 360.
