Triggering a change in audio volume
Nov 08, 2016
I have an MP3 audio track over a screencast on one of my slides, and at a specific point a few seconds of video are shown in the screencast. I'd like to lower the MP3 audio track to a very low level so the audio of the video can be clearly heard, then raise it back to normal volume when the video element finishes.
I know I can pause and restart the audio track based on timeline/markers, but this is quite abrupt, and I think a reduction in volume would work much better.
Can anyone tell me if this is possible, and if so how?
TIA
Duncan

Import your audio file, then double click the file to open it in Storyline's audio editor. Select the portion of the audio you want to lower the volume on, and select Volume from the toolbar. Then you can play with it to get that portion where you want it.
Hi Duncan,
Is the fading effect you're wanting "time" based, meaning that it happens at the same time each time the slide plays, no matter what the user does on the slide? If so, you may consider using an audio editor to achieve this - this forum thread should start you in the right direction.
I'm sure other folks in the community will have tips to share, as well!
Thanks Sandra, that was useful and it solves my problem in part. Would be nice if I could automatically fade it out in the editor, without having to fiddle with lots of mini volume reductions to make the effect though.
I don't want to alter the original audio file, Alyssa, as this would have to be completely redone every time I made a slight alteration to the timeline of my slide. Ideally I'd rather set a trigger that fades the volume to +/-X% when run. Maybe something for a future update. :)
That's a great idea, Duncan! I encourage you to share your perspective with our product development team here. We take feature requests seriously and love to get ideas from our customers!
