Hello,

I am hoping to play a song that continues throughout my project (background audio), but be able to have slide audio (narration) that turns on as an option for learners that need/want it.

I know I can mute the audio via advanced actions, but that mutes all audio. I also read several people say that you shouldn’t use background audio if you want to control your audio. However, I believe Captivate is limited to using background audio or attaching audio to an object that plays to end of the project if you want a song to continue across slides. None of this knowledge appears to help me in this situation.

Thanks in advance for any help, suggestions, or feedback.

Mark

It can be done with audio objects, as you understood, but also with the Play Audio command.

Personally I would prefer the second scenario. Import all the audio clips to the Library. If you create them with TTS, you’ll need to do that manually, because they will always be inserted as slide audio.

You need a user variable (Boolean), which I will label v_narrate. Its default value is 0 (no narration). If the suer clicks a button to turn it on, it will get the value 1. (use Assign or Toggle command).

Create a shared action, which will be triggered On Enter for each slide:

IF v_narrate is 1

Play AudioClip
Continue

ELSE

Continue

The only parameter is the audio clip.

That is not possible.  I have been blogging a lot about Captivate’s Timeline, and the way different types of audio are handled by the timeline. Slide audio is visible on the timeline and will always play when the playhead moves throughout the timeline.  <The only way to m stop it is the mute command, but that will mute all audio.

Can you tell me if you choose for Slide audio because you need Closed Captioning? If not, two other types of audio can be controlled: both audio objects and audio started with the ‘Play Audio’ command. After you answered my question about CC, will explain more in detail.

I want to make a project with background music and no narration. However, I need to have on-demand robot narration for learners that need/want it.

I could probably have a button control a variable indicating if the narration is on/off. Then on each slide have an advanced action on the entry that would show/hide an object with the narration attached (assuming audio attached to hidden objects doesn’t play). This sounds like alot of work though, and there really should be a way to control narration in the same way you can control closed captioning, seeing as they are both matters of accessibility.
