USING ADOBE CAPTIVATE 5
Audio
Last updated 4/22/2010
Creating audio in Adobe Captivate is essentially a two-part process. You record audio in WAV format, and then Adobe
Captivate converts the WAV file into an mp3 file. When files are in WAV format, they have a degree of flexibility. You
can edit and adjust them “downward,” compressing them into mp3 files uniquely tailored to their playback scenario.
When working with audio, keep your users in mind. If a user is likely to access the Adobe Captivate project by using
a dial-up modem, use a higher compression/lower sampling rate, such as 56 Kbps. However, if you are distributing the
project on a CD-ROM, you can use a lower compression/higher sampling rate, such as 144 Kbps. In the best
development case, experiment to find the optimal balance between sound quality and file size for your users.
Using Adobe Captivate, you can record an audio file for a single slide, group of slides, or for the entire project.
Note: For slides with unique audio files, the Timeline of the slide is stretched to meet that of the audio file. However, audio
files for a project are cut short if they exceed the project Timeline.
1 In an open project, select Audio > Record to and select one of the options:
Slide Record the audio file for the selected slide.
Slides Record the audio file for a group of slides starting with the selected one. To finish defining the range of slides
included in the group, enter a slide number in the To field of the Record Audio dialog box.
Background Creates background audio for your project. For details, see “Create background audio” on page 136.
Object Sets audio for a selected object on the slide.
2 In the Audio dialog box, configure the following according to your preferences:
SWF Preview The recording window displays a Preview panel where you can view the project as the audio gets
recorded.
Continuous Play Select this option if you want the file to play until the end of all the selected slides or the end of the
project.
Captions and Slide Notes Use these options when you want to record voice-over narration that matches the
caption text or slide note text. Read aloud the text that you have added to these areas when recording audio.

• CD Bitrate (128 Kbps) Specifies the amount of audio information (in Kbps) that will be stored per second of a
recording, which is of CD quality.
