Associating CD Tracks as Soundtracks
Adding a CD audio clip to a slide is much like adding a regular sound clip. You place the clip on the slide, and a little CD icon appears that lets you activate the clip. Then you can set properties for the clip to make it play exactly the way you want. It's different, however, in that the audio track is not stored with the presentation file. (It's too big!) Therefore, the audio CD must be in the CD drive of the computer that you're using to present the show. You can't use CD audio tracks in presentations that you plan to distribute on self-running data CDs or over the Internet because the computers on which it will run will not have the audio CD.
To play a CD track for a slide, you must place an icon for it on the slide (or drag the icon off to the side of that slide). You can actually place a range of tracks, such as 1 through 4 from a CD, using a single icon.
Placing a CD Soundtrack on a Slide
To place a CD icon on a slide, follow these steps:
Choose Insert⇨Movies and Sounds⇨Play CD Audio Track. The Insert CD Audio dialog box appears.
Enter the starting track number in the Start at Track box under Clip Selection (see Figure 12-11). The default is 1.
Enter the ending track number in the End at Track box. The default is the last track on the CD.
| Note | If you want to play only a single track, the Start at Track and End Track numbers should be the same. If you want a range of tracks, make the range inclusive of the last track; for example, if you want 1, 2, and 3, put track 3 as the ending track (as opposed to track 4). |
| Caution | If the End at Track appears as 1 with a time of 00:00 seconds, PowerPoint is not correctly reading your CD. You will be able to place the CD icon on the slide, but the CD tracks will not play during the presentation. Try removing and reinserting the CD in the drive. Or, if you have two CD drives in your computer, try putting the CD in the other one. On some systems PowerPoint will only see the CD drive with the lower drive letter. For example, if the CD drives are D and E, it will only see D. |
If you want to begin the starting track at a particular spot (other than the beginning), enter that spot's time in the Time box for that line. For example, if you want to start the track 50 seconds into the song, enter 00:50.
The end time that appears for the End at Track is the total number of seconds from the starting point to the end of the specified track. If you want to end the ending track earlier than that, decrease that number of seconds.
Click OK. A message appears asking whether you want it to play Automatically or When Clicked. Make your selection.
The CD icon now appears in the center of the slide. Drag it elsewhere if needed, or drag it off the slide completely (provided you do not need to click it to play it). You can also resize its icon as you would any graphic.
Figure 12-11: Specify the starting and ending track, and optionally, a time within those tracks.
Making a CD Soundtrack Continue Across Multiple Slides
By default, a CD soundtrack plays only when the slide on which its icon appears is displayed on-screen. If you want the CD to continue playing across multiple slides, do the following:
Right-click the CD icon and choose Custom Animation. The Custom Animation task pane opens.
In the task pane open the menu for the CD clip and choose Effect Options. The Play CD Audio dialog box appears with the Effect tab on top.
Enter 999 in the box for Stop Playing After-slides (see Figure 12-12). Then click OK.
Figure 12-12: To play across multiple slides, set the Stop setting to 999 slides.
| Tip | I always use 999 as the setting in step 3 to head off any possible problems. When another track plays, the first one will stop. For example, suppose you have a 30-slide presentation, and you want to play tracks 2, 4, and 6 from your CD, each for 10 slides. On slide 1, you would insert track 2 and set its custom animation to stop playing after 999 slides. Then you would do the same thing for track 4 on slide 11 and track 6 on slide 21. Don't worry about the tracks playing over the top of each other-they won't. (However, file-based sound files, such as WAV, do play on top of each other, so you would not typically layer them in this way.) |
You can play any number of tracks from a single CD using a single icon, as long as they are contiguous and you play them in their default order. If you need non-contiguous tracks from the CD or in a different order, or you just want certain segments of some of the clips, you must place each one individually on the slide and then control their order with Custom Animation. If you don't want the icons to appear on the slide, drag them off the edge.
| XREF | See Chapter 13 for help with custom animation. |
Using a Soundrack in a Web Presentation
In a Web presentation, you can't use CD audio (obviously, because your audience won't have that CD). Instead, you must use a music file in a digital format like Windows Media Audio (WMA). Copy that music file to the same Web location as the rest of the HTML files for the presentation.One glitch with a soundtrack in an HTML presentation is that the music plays only on the first slide; then it stops. To make it play throughout all slides, you must edit fullscreenl.When you save a presentation in HTML, one of the files that is created is called fullscreenl. Edit this file with an HTML editor (or plain-text editor), to add the following line between the <html> and <head> tags at the beginning:
<bgsound src=" loop=infinite>
Substitute the actual name of the music file for .
