Adobe Presenter 6

Adjust audio volume

You can adjust the volume of audio files included in your presentations. After adjusting the volume, preview the presentation to see if the sound level is acceptable.

  1. In PowerPoint, open a presentation (PPT file) containing audio files.
  2. From the Adobe Presenter menu, select Audio Editor.
  3. From the Tools menu, select Volume.

    The Adjust Volume dialog box appears.

  4. Click the volume slider on the left, and drag it up to increase volume, or down to decrease volume.
  5. You can change the audio processing options, as follows:
    Normalize
    Adjusts the sound volume automatically. Normalizing audio helps keep the sound level consistent between slides.

    Dynamics
    Amplifies quiet sections of the audio to help compensate for variations in audio volume.

  6. (Optional) Click Advanced Controls.
    Ratio
    Specifies the maximum amplification that Presenter will use. 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 a project that has large disparities between quiet and loud sections, but can also amplify background noise.

    Noise Threshold
    Controls the amplification of background noise. Presenter doesn’t amplify any sound below the threshold. If background noise is amplified too much, try a higher noise threshold. (Note that the Dynamics option does not work well with high noise levels.)

  7. When you finish, click OK twice to close all the dialog boxes.
