Q: I want to add some music for the flash book, what can I do to insert as background sound file?
A: If you want to add background sound to your flash book, such as a song or other audio file, you just need to set "Sound" part in "Design Setting" panel:
Click "Sound File->…" to choose MP3 file from your computer, then set "Sound Loops", "-1" stands for playing the sound file all the time while viewing the flash book, other value (N>0) stands for the times of playing the sound file.
