Using PowerPoint as a slide show, sometimes we need to add background music to all the slides to render the atmosphere and enhance the demo effect. But the background music that you insert by using the movie and sound in the Insert menu bar → Sound in the file only works for the selected slide, and the background music stops playing when the next one is played. How to solve this problem?
In fact, we simply set up in the "Custom Animation", you can easily control the background music in the specified part or all of the slide play, as follows:
1, do all the slides, in the need to insert the sound of the slide, click on the Insert menu, "movies and sounds" → "sound in the file", select the sound file you want, in the "Do you need to play the sound automatically during the slide show?" dialog box, select Yes (Figure 1).
2. If you are working in PowerPoint 2000, right-click the new sound icon "Small horn", select "Edit Sound Image", tick the "loop until stop" option (see Figure 2), and finally click OK. (in order not to affect the visual effect of the slide, you can drag the small horn to the lower-right corner of the slide at this point.) )
3, right click on the sound icon "small horn", select "Custom Animation", open the Custom Animation window (Figure 3), click "Continue slide Show", when the following "Stop playing" item will be not operational gray into solid color. Next, click the After slide item, and then fill in the box with the number of slides you want to stop playing, and then click OK. (You can also place "hide without play" tick, so that no sound icon will be displayed during the slide show.) )
This specifies the background music that can be played continuously on several slides.
If you are working in Office PowerPoint 2003, the 2nd step, as shown in Figure 4, has a "display option" to choose from, and we can check the "Hide sound icon during slide Show" item so that the sound icon does not appear during the slide show.
and the 3rd step right click on the sound icon "small horn", select "Custom Animation", the Custom Animation window that is open also changes, as shown in Figure 5: At this point, we can left-click the "one-snip-wma" button in the Custom Animation window or right-click on "Cut plum. wma" and select "Effect Options". The Playback sound window appears as shown in the following figure (Figure 6). Click the After slide item, and then fill in the box with the number of slides you want to stop playing, and then click OK to complete the setup.
