When importing audio files into Articulate Storyline 3, which method produces the smallest file sizes and quickest download times when published to web?
Are uncompressed WAV files compressed when exported to web and if so to which format?
Could you also advise if file sizes can be reduced further by importing MP3s into Storyline?
When you insert audio files into Storyline, we'll automatically compress them as a part of the publishing processed.
When you record narration in Storyline, MP3 files are generated with an audio bitrate of 192 kbps. These audio tracks are stored in your project file.
When you publish, the MP3 files get re-encoded at the audio bitrate you choose in the quality settings.
Standard quality uses an audio bitrate of 56 kbps.
Custom quality lets you select an audio bitrate between 16 kbps and 160 kbps.
Optimize Audio Volume normalizes audio throughout your course for consistent volume across all slides. If your course audio already has consistent volume, you can speed up the publishing process by unchecking this option.
Storyline does a lot of work behind the scenes to compress the whole course into the smallest possible file size - audio files or not. If you're seeing an odd behavior with that file size, let us know - we'd want to take a look at the .story file!
