## Adjust volume dialog box

Use this dialog box to edit audio volume and select audio processing options.

Volume: Use this option to increase or decrease the sound level of the audio file. Drag the slider bar lower to reduce the volume, or drag it higher to increase audio volume. (As you drag, the percentage increase or decrease in volume is displayed at the bottom so you can precisely adjust the sound.)

Normalize: Select this option to have Captivate adjust the sound volume automatically. Normalizing audio helps keep the sound level consistent among 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 to 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 movies 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. (The Dynamics option does not work well with high noise levels.)
