Edit audio files

  1. In PowerPoint, open a presentation (PPT or PPTX file) containing audio files.
  2. Click Adobe Presenter, and in the Audio group, click Edit.
  3. Use the buttons and menu options to make any necessary edits. You can cut and paste sections of the audio file, insert periods of silence to lengthen the audio file, adjust volume, import a different audio file, and more.

    Cut

    To cut the selected portion of the audio file.

    Copy

    To copy the selected portion of the audio file.

    Paste

    To paste information from the clipboard. (For example, if you select a section of the audio file, and then click Cut or Copy, Adobe Presenter places the selected audio on the clipboard. You can then click Paste to place the audio back into any location within the audio file.)

    Delete

    To remove the selected portion of the audio file.

    Undo

    To undo the previous action.

    Redo

    To redo the previous action.

    Zoom

    To enlarge or shrink the waveform.

    Record Over/Insert Recording

    To begin recording audio. (A microphone is required.)

    Play

    To start playing the audio file.

    Pause

    To temporarily stop the slide from playing. (Click Play to resume playing the audio file.)

    Stop

    To end the playback of the audio file.

    Playhead

    To specify the selected location, in seconds, within an individual slide on the waveform. For example, if you are working with a slide that is 5 seconds long and you click in the middle of the slide on the waveform, this playhead area displays approximately 00:00:02.500.

    Selected

    To specify the total playing time of the presentation, if no span of time is selected on the waveform. If you have selected a span of time on the waveform, this area displays the amount of time selected.

  4. When you finish editing the audio file, click Save.

Preplay audio

A quick way to listen to the audio you added to a presentation is to play the slide show directly from within the Edit Audio dialog box. Click in the Edit Audio dialog box and then click play ().

Add silence to an audio file

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

  • If you import an audio file and must 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 an FLV file with audio, such as sidebar video of a speaker, into a presentation and want to synchronize the FLV file audio with slides

To add silence:

  1. In PowerPoint, open a presentation (PPT or PPTX file) containing audio files.
  2. Click Adobe Presenter, and in the Audio group, click Edit.
  3. 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. Click .
  5. In the Insert Silence dialog 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.

    Adobe Presenter adds the silent period to the audio file and displays the period on the waveform.

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

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 or PPTX file) containing audio files.
  2. Click Adobe Presenter, and in the Audio group, click Edit.
  3. In the Edit Audio dialog box, click .
  4. In the Adjust Volume dialog box, 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. Click OK.
  7. When you finish editing the audio file, click .

Import slide notes

If you have created slide notes in PowerPoint, you can import the notes into the script window in the Record Audio dialog box. Importing notes is useful if you want to use the slide notes as a script when recording an audio file as voice‑over narration.

  1. In PowerPoint, open a presentation (PPT or PPTX file).
  2. Click Adobe Presenter, and in the Audio group, click Record Audio.

  3. In the Record Audio dialog box, click the Show Script icon ().

    The slide notes are imported.

Manage audio clips and files

Adobe Presenter lets you edit the timing of audio files after you record or import them. Having control over the timing of audio files gives you the ability to use audio files of different lengths and incorporate them smoothly into presentations.

After you record or import an audio file, the file appears as a waveform in the Edit Audio dialog box. If your presentation contains multiple audio files, you can see which audio files are assigned to specific slides.

Edit audio timing

  1. In PowerPoint, open a presentation (PPT or PPTX file) containing audio files.
  2. Click Adobe Presenter, and in the Audio group, click Edit.

    In the Edit Audio dialog box, Adobe Presenter displays any audio files incorporated into the presentation as waveforms. Slide numbers above the waveform show exactly how the audio files are currently distributed across the slides. Adobe Presenter lets you import or create an audio file and then distribute that audio file across multiple slides.

Change how audio files are distributed across slides

In the Edit Audio dialog box, click the red slide marker line and slide the divider to the left or right.

The waveform remains static, but you can change where the audio file begins to play within the presentation. This option is useful if you have a long audio file and need to experiment with assigning the file to one slide or having it play over multiple slides.

Jump to a specific slide during audio narration

At times, during audio narration, you may want to explain or present content that is on another slide. In such cases, you can use the Go To Slide marker to jump to the required slide.

  1. In the Edit Audio dialog box (Adobe Presenter > Audio group > Edit), click play to play the audio.
  2. Pause the audio at the point where you want to jump to the required slide.
  3. Click Insert Marker ( ).
  4. In the Marker Type list, click Go To Slide, and click OK.

Pause the presentation during audio narration

If you want the presentation to automatically stop at a specific point and wait for the user to continue by clicking play in the Playbar, do the following:

  1. In the Edit Audio dialog box (Adobe Presenter > Audio group > Edit), click play to play the audio.
  2. Pause the audio at the point where you want to jump to the required slide.
  3. Click Insert Marker ( ).
  4. In the Marker Type list, click Wait For User, and click OK.

Listen to an audio file

In the Edit Audio dialog box, click a location within the waveform, and then click Play in the lower-left corner of the dialog box or press the spacebar on your keyboard.

The audio plays from the location you selected to the end of all audio in the presentation. (You can stop the playback at any time by clicking Stop in the lower-left corner of the Edit Audio dialog box or pressing the spacebar on your keyboard.)

Zoom in on an area of the waveform

In the Edit Audio dialog box, click the waveform, and then click Zoom In  or Zoom Out   in the tool bar. (Alternatively, click in the waveform and roll your mouse wheel to zoom in and out).

The scale at which you are viewing the waveform is shown in the Scale information box in the top-right corner of the dialog box.

After you have added audio files to your presentation, you can use the Edit Audio dialog box to cut or copy entire audio files or portions of audio files and paste them in a new location.

Cut or copy and paste audio

In the Edit Audio dialog box, select a section of an audio file directly on the waveform, click Cut  or Copy  , click a different location on the waveform, and then click Paste  .

Delete an entire audio file or portion of an audio file

In the Edit Audio dialog box, select a section of an audio file directly on the waveform and click Delete.
