Editing audio timing
Adobe Captivate lets you edit the timing of audio files after you record or import them. Having
control over the timing of audio files gives you the ability to use audio files of different lengths
and incorporate them smoothly into projects.
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.
From the Audio menu, select Edit timing.
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 at the top of a
red slide marker line and slide the divider 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.
