Why do Audio clips get truncated in Cp 9?

[danpatlee]

Hi, my Cp9 course features a dialog between two characters. Their lines appear as text boxes in word balloons, and the audio for each line plays when the text appears. At different spots, not always the same, the audio is truncated and the last word or so gets cut off. 

As a possible remedy, but to no avail, I increased the length of each slide to go a couple of seconds past the end of the last audio clip, and put in a "continue" button.  When playing the slide again, the audio plays perfectly, suggesting that there might be a caching issue or something.

Thanks in advance to anyone who knows how to solve this very vexing problem.

Make sure whenever you add silence to extend an audio clip in Captivate that you use "dirty silence", meaning that the silence still contains some audio data and is not perfect silence.  Captivate always clips off complete silence for some reason.

Hi Rod,

So you're saying that I could add some "dirty silence" to an audio clip and Cp9 might truncate off that last bit instead of the actual content? I guess I could try that.

Thanks, I'll let you know what happens.

Hi Rod,

Well,  I went through and added one or two seconds of dirty silence to every single audio clip, with no improvement. Also set the Preloader to 100% in case the thing needed more time to load.

Any other thoughts?

Thanks in advance,

Dan

When you add "dirty silence" to either beginning or end of the clip Captivate normally does NOT truncate that part.  It will usually only truncate clean silence.

Since it appears that you are using Object Audio (audio attached to objects) have you tried lengthening the duration of those objects on the timeline?  Try making each one a few seconds longer than you think it should need to be and see what happens.

Thanks Rod. Possibly my silence was not quite "dirty" enough. I don't think the object length is the issue because each one goes for at least a couple of seconds past the audio. But I'll check on that as well.
