Hi Emily,
You can record audio to 3 slides in different ways.
Option1 :
You can record audio individually on all the three slides by invoking the Slide audio dialog for every slide.
1. On every slide you wish to record audio invoke the slide audio dialog ( from Audio >> Record to >> Slide ) and record for the single slide. Saving the recorded audio will add it to the slide you recorded.
2. You can follow step 1 for all the three slides you wish to record.
Option 2:
You can record audio to all the three slides continuously in one go. You can do this in the SLIDES audio dialog
For ex if you want to record audio for slides 1,2 and 3, then select slide 1 and invoke the slides audio dialog from Audio >> Record to >> Slides
You get a "Record from Slide" dialog. Enter the Slide numbers for which you wish to record audio and click ok.
This will open the slides audio dialog.
Slides audio dialog shows up the slides selected in the "Record from slide" dialog. Enable "Continuous play" and "SWF Preview" and Click on the recording button. This will record audio over the three slides as you narrate. Audio will be added to all the three slides. You can see the Movie (SWF) preview or the Slide number mentioned in the top right of the preview pane to know the slide number you are recording to.
If some portions of the audio spills over the next slide then you can arrange the markers in the EDIT tab. Here you can play the audio and pause at the point where you want your next slide to start and click on the button highlighted by Lilybiri. Its called the "Start Next slide here" button.
After all the recording is done click on SAVE to add audio to all the three slides.
Try out these and let me know if it works.
