99 Impress with Animation Effects

You can add sound to your presentations to accent an effect or to get your audience's attention during slide transitions. Impress supports the following sound file extensions and formats:

  • AU and SND files (SUN/NeXT)

  • WAV (Microsoft Windows)

  • VOC (Creative Labs SoundBlaster)

  • AIFF (SGI/Apple)

  • IFF (Amiga)

Surprisingly, there appears to be no way to provide timed narration throughout an entire presentation, as you might want for an automatic presentation. Nevertheless, Impress does support enough sound techniques to pique your audience's attention.

NOTES

As with all special effects, don't overdo the use of sound; otherwise, it will distract from your presentation.

You can insert a sound file at any place in a slide by selecting

Insert, Object, Sound and navigating to the sound file you want to insert. However, the sound only plays when you double-click it, so this method is not very useful for most presentation purposes.

1.

Select an Object to Apply Sound To

Click to select an object on a slide, such as a graphic image or text box. You can attach a sound to this item for a special effect.

2.

Request Interaction

Select

Slide Show, Interaction to add a sound to the selected image. The

Interaction dialog box appears.

3.

Play the Sound at Image Click

Click to open the

Action at mouse click list box and select

Play sound . You have just told Impress that you want to play a certain sound when you click the image.

4.

Locate the Sound

Browse your hard disk or network to locate the sound to play. Use the

Play button in the Open dialog box to listen to a sound before deciding whether to insert it. Click

OK to attach the sound to the image. When you give your presentation (assuming it's not an automatic presentation, where you cannot add sound linked to a mouse click because no human presenter will be there to click the mouse), you can click the image to produce the sound through the presentation computer's sound card. You can test the sound effect by clicking it from within the Drawing view without having to run your presentation. (To add sound during an automatic presentation, you can select an action such as

Action when slide appears .)
