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.
