Setting a Clip to Continue across Multiple Slides
To set a fade duration, follow these steps:
1. Select the clip’s icon on the slide.
2. On the Audio Tools Playback tab, enter a number of seconds in the Fade In box.
3. Enter a number of seconds in the Fade Out box.
Setting a Clip to Continue across Multiple Slides
Normally a clip will stop playing after it has played once (or however many times you have
set it up to play) or when you click the mouse or advance to the next slide. However, if you
are using a music track such as an MP3 fi le, you might want it to continue playing across
multiple slides.
Earlier in the chapter, you learned how on the Audio Tools Playback tab you can mark the
Play Across Slides check box or click the Play in Background button. When you do either of
those things, PowerPoint sets up that sound to continue playing through 999 slides (or as
many slides as you have, if fewer than that).
If you would like the clip to stop after fewer slides than that, you must adjust the Stop
Playing setting in the Play Audio dialog box. Follow these steps:
1. In the Animation pane, right-click the clip and choose Effect Options. The Play
Audio dialog box opens with the Effect tab displayed.
2. In the Stop Playing area, choose one of these options:
On Click to go back to the default play mode (same as choosing Start on Click
After Current Slide to stop the audio when you move to the next slide or when
the clip has fi nished playing, whichever comes fi rst. This setting allows the clip
to continue playing through mouse clicks, as long as the slide does not advance.
After _____ Slides , and then enter a number of slides; the audio will continue
until the specifi ed number of additional slides have passed. Use 999 for the
entire presentation, or use a smaller number, as in Figure 14.15.
3. Click OK.
What if you want to jump around in an audio clip? For example, suppose you want to play the i rst 20 seconds of the
clip and then skip to the 75-second point. You can do that by inserting two separate copies of the clip. Set each one
with the start time desired for it, and then in the Animation pane, set one of them to After Previous and make the
other copy the previous animation event. Alternately, you can set bookmarks on the audio control and then add trig-
gers to the bookmarks. (That latter method has the advantage of keeping the i le size smaller because you have only
one copy of the clip in the presentation.) Those instructions will make more sense to you after you have read Chapter
16, which covers custom animation effects in detail.
