I've added a music file as background music on one slide.
Basically, there's text (a few sentences) and while learners read, there's music.
However, the slide 27 seconds long. I wondered if there's a way to make the slide's length shorter, for example 5 secs? I've tried " Audio Edito" by shortening the slide, but it always reverts back to 27 seconds.
The audio file (music) is 2 minutes long.
