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.
So far I've shown you a number of ways to insert sound effects and audio clips in to your presentation. You have the ability to extend your sound so that it plays across any number of slides. Let's take a look at all the different places where you can control that setting. By default, when you move to the next slide your sounds stop automatically. On my title slide, I have some light music that I had like to play during my first two slides and I have a bee buzzing that I'd like to play from my last two slides. Click on the sound icon, and go to the Audio Tools Playback tab.
Where it says Start On Click, change this to Play Across Slides and when you get to the next slide, the sound will still keep playing. Now when you choose this setting, PowerPoint will also start to play the clip automatically. If you still want to start to playback manually by clicking on the button, go to the Animations tab and on the right- hand side change Start Back to On Click. If your sound clip is short and you need it to it to repeat itself until you reach that desired number slides, go back to the Audio Tools Playback tab and click on Loop until Stopped.
Now the clip will repeat itself as you move through the slideshow instead of stopping when the first time through. Since we don't want to it to loop indefinitely through the whole slideshow, we just want the clip to play for two slides, go back to Animations Ribbon and on the right-hand side, turn on the Animation Pane. Click on the dropdown arrow next to our sound clip and select Effect Options. In the middle section called Stop Playing, the last option says After and you can choose the number of slides.
Because we already said it to Play Across Slides, you will see a 999 here. Set it to the maximum so that there's no concern about adding slides and accidentally stopping short. But when you need it to, this is the place to tell it to Play Across two slides or ten slides. So since we're going to play reset for two slides, delete the 999 and type 2. Now click OK. Now let's look at another technique. If you've applied a sound to a slide transition as I showed you how to do in the previous chapter, you can set it so that sound doesn't stop after it is played once.
Click on slide 3 and then go to the Transitions tab and on the right-hand side of the Ribbon there's an option for Sound. When you drop down the list, you could choose any of these sound effects but personally I wouldn't want to loop this constantly. I'll click on other sound at the very bottom and I will navigate to my bee. Don't forget as I've showed you in the movie about Transition Sounds, your own transition effect must be wave files. I'll click OK.
(Bzzzzz) Now click on the dropdown next to Sound one more time. At the very bottom, there's a checkmark that toggles on and off Loop Until Next Sound. Click on this. This will play the transition sound repeatedly until you choose another sound on another transition. If you click on slide 5, you can see that I've already selected the wave file Wind. Now when I go to slide one and play my slideshow, my sound will start on slide one when I click on it and continue through slide two.
Then my bee buzz transition sound will play from 3 to 4 until I get to slide five and another transition sound plays. Let's hear it. (Music playing) (Bzzzz) The ability to span your Audio Effects across slides allows you to continue to provide content even as long sounds play and to continue sounds as long as they support your point.
As always, make sure you choose sounds which further understanding of your concept so they're neither gratiutous it is nor annoying to your audience.
