Adobe Presenter 6

Add silence to an audio file

You can add a period of silence to any audio file that is part of a Presenter presentation. This feature is particularly useful in the following situations:

  • If you import an audio file and need to synchronize the audio with slides

  • If you need to make an existing audio file work in a presentation without having to edit the audio extensively

  • If you have inserted a Flash file with audio, such as a “talking head” video of a speaker, into a presentation and want to synchronize the Flash file audio with slides

  1. In PowerPoint, open a presentation (PPT file) containing audio files.
  2. From the Adobe Presenter menu, select Audio Editor.
  3. Use the Audio Editor to add silence anywhere in a presentation, including a specific location within an audio file. Click the location in the presentation, or the exact location within an audio file, on the waveform to which you want to add the silent period.
  4. From the Insert menu, select Silence.
  5. In the Insert text box, enter a number specifying the duration of silence (in seconds).
  6. In the Seconds at text box, specify where to add silence:
    Cursor Position (default)
    This option adds silence at the point in the waveform you selected in step 3.

    Start of Slide
    This option adds the silent period to the beginning of the slide containing the location selected in step 3.

    End of Slide
    This option adds the silent period to the end of the slide containing the location selected in step 3.

  7. Click OK.

    Presenter adds the silent period to the audio file and displays it as a waveform.

  8. To test the audio file with the silence added, click Play in the lower-left corner of the Audio Editor dialog box.
