Adding silence to an audio file

You can add a period of silence to any audio file that is part of an Adobe Captivate project. This feature is partic-
ularly useful if you have imported an audio file and need to synchronize the audio with objects and slides. By
adding silent periods, you can make the existing audio file work in an Adobe Captivate project without having to
edit the audio extensively.
To add a silent period to an audio file:
Open an Adobe Captivate project that contains audio files.
1
Select a slide that contains an audio file. (In Storyboard view, slides containing an audio file display the audio
2
icon beneath the slide.)
Select Audio > Edit Timing > Slide or Project depending on your preferences.
3
Note: Edit Timing is enabled if a question slide or a project slide contains an audio file. It is disabled in the question
pools mode, and for random question slides.
The Edit Audio dialog box appears.
4
You can add silence to the beginning of the audio file, to the end, or to a specific location within the audio file.
5
If you want to add silence within the file, click the exact location directly on the waveform.
Note: The Playhead and Selected information boxes near the bottom of the dialog box can help you choose a precise
location in the audio file. For example, if you want to add a silent period four seconds into the audio file, click the
waveform until the Playhead information box displays a number close to four seconds (that is, 00:04.00).
Click Insert Silence.
6
The Insert Silence dialog box appears.
The silent periods you add to the audio file are measured in seconds. In the Insert box, type a number to specify
7
the length of the silent period.
In the text box to the right, click the pop-up menu and select the position in the audio file to which you want
8
to add the silence. The choices are Playhead position, Start of audio, or End of audio.
Note: When you select a part of an audio file, and then click Insert Silence, the pop-up menu lists the Current
Selection option instead of the Playhead position option.
Click OK.
9
The silent period is added to the audio file and you can see the silent period in the waveform. The audio file with
added silence is saved under a new file name.
To test the audio file with the silent period added, click Play in the bottom left corner.
