Discover how to integrate and enhance video and audio to create a more engaging PowerPoint presentation. In this course, author Alicia Katz Pollock emphasizes the technical details necessary to make a multimedia presentation work: from working with appropriate file formats, to applying video styles, to reducing the file size of multimedia presentations for sharing.
If you'd like the sound to repeat itself until you manually stop it, use the Loop until Stop feature. That way, it will keep playing indefinitely until you click your mouse again. Here on my title slide, I have a music clip that I want to play when my audience is getting seated. Now normally I would have a full song here set to repeat itself until my presentation starts. But to make the loop effect more obvious, I'm just going to use a very short clip. Click on your audio clip to select it, then go up to the Audio Tools Playback tab.
In the center are a series of Audio Options. Find the option that says Loop until Stopped and click on its check mark. Now when I play the slideshow--- (Music playing) --as soon as the sound clip reaches the end, it starts over. If I want to pause the clip, click Pause on the Audio Playback Controls. To advance to the next slide, just click your mouse on the slide background. I'll hit Escape and go back to slide one.
Now there's another way to set the clip to loop indefinitely found with the Animation Settings. Click on the Animations tab and then open up the Animation Pane with this button on the right hand side. Here's our sound. Click on it and then click on the dropdown arrow and choose Timing. In the dialogue box that appears, click on the drop down next to Repeat. Right now because we've already set the clip to loop. It says Until End of Slide.
Here you can loop the audio a specific number of times instead of leaving it to play indefinitely. If you set to play 2, 3, 4, or 10 times in a row it will just stop automatically. If I change this to Until Next Click, when I'm playing the slideshow and I click my mouse, instead of going to the next slide and stopping the audio, just the audio will stop and I can remain on the slide. I'm going to choose 3 and then click OK. Now when I play the slideshow my sound will loop. (Music playing) Setting these options when looping your audio clip allows you to play a sound repeatedly while you remain on one slide.
Being able to specify the number of loops or when to stop it makes this feature that much more powerful.
