ADOBE CAPTIVATE 3 121 User Guide Tip:If you find that you frequently want to add silence at the same position and of the same duration, press ALT+S to add it without using the Insert Silence dialog box. Adjusting audio volume You can adjust the volume of audio files included in your Adobe Captivate projects. To adjust the volume of audio files: 1 Open an Adobe Captivate project that contains audio files. 2 Select a slide that contains an audio file. (In Storyboard view, slides containing an audio file display the audio icon beneath the slide.) 3 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 dialog box appears. 4 Click Adjust volume. The Adjust Volume dialog box appears. 5 To change the volume, click the volume slider on the left side and drag it up to increase volume or down to decrease volume. 6 If you want, change audio processing options: Normalize Select this option to have Adobe Captivate adjust the sound volume automatically. Normalizing audio helps keep the sound level consistent between slides. Dynamics Select this option to amplify quiet sections of the audio to help compensate for variations in audio volume. • Ratio Specifies the maximum amplification that will be used. The default setting of 2.0 sets the quietest sections of the audio to be amplified by a factor of 2. A higher setting can improve projects with large differences between quiet and loud sections, but can also amplify background noise. • Noise Threshold Controls the amplification of background noise. Anything quieter than the noise threshold is not amplified. If background noise is amplified too much, setting a higher noise threshold may help solve the problem. (Note that the Dynamics option does not work well with high noise levels.)
