Is it possible to attach audio to multiple slides (not all) as described? If so, how?
Slide 1: no audio; text communicates that this module will have audio, so the viewer needs to prepare by plugging in headphones. Click Start Video button when ready. Goes to next slide.
Slide 2: Music audio begins (object) and voice narration enters a few seconds later, recorded to slide. Intro slide finishes, audio fades.
Slide 3-30
Each slide has voice narrated to slide. I would like add a SECOND music file to play in the background, across all slides from #3-20.
Slide 21-23: Original music plays on these slides, each with voice narrated to background.
Many Thanks.
