Adding audio and video
After you record or import an audio file, the file appears as a waveform in the Edit Audio Timing dialog box. If
your project contains multiple audio files, you can see which audio files are assigned to specific slides.
To edit audio timing:
1 Open an Adobe Captivate project containing one or more audio files.
2 Select Audio > Edit Timing > Slide or Project depending on your preferences.
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 Timing dialog box appears.
Audio files in the Adobe Captivate project are displayed as waveforms. Slide numbers are shown along the top of
the waveform so you can see exactly how the audio files are currently distributed across the slides.
•
To change how audio files are distributed across slides, click on a slide divider and move it to the left or right.
The waveform remains static, but you change where the audio file begins to play within the Adobe Captivate
project. This option is particularly useful if you have a long audio file and need to experiment with assigning
the file to one slide or having it play over multiple slides.
•
To listen to audio, click a location within the waveform and then click Play. The audio plays from the location
you selected to the end of all the audio in the project. (You can stop the playback at any time by clicking Stop.)
•
To zoom in on a particular area of the waveform, click on the waveform and then click zoom in or zoom out.
(Alternatively, click in the waveform and roll your mouse wheel to zoom in and out). The scale at which you
are viewing the waveform is shown in the Scale information box near the lower-right corner of the dialog box.
•
To cut or copy and paste audio, select a section of an audio file directly on the waveform, click Cut or Copy,
click on a different location on the waveform, and click Paste.
•
To delete audio, select a section of an audio file directly on the waveform and click Delete.
•
You can insert a silent period within an audio file. If you want the silent period to begin in a specific location
within an audio file, click the location directly on the waveform. Click Insert silence. Type in the length of the
silent period you want to add and then click on the pop-up menu to select a location for the silent period: the
location you clicked on the waveform, the beginning of audio, or the end of audio.
•
To adjust the sound level of audio files, click Adjust volume. Use the slider bar to increase or decrease volume
and select audio processing options.
•
To set recording device and audio quality options, click Settings.
