Add background sound to video

Hello everyone, I want to create a movie from a set of images, and that I know how to do. Is possible to add a background sound as background "music" ?

Thanks!

If it is to become part of the movie, rather than being played at the same time as the movie, then the only supported way is to use Computer Vision Toolbox.

Playing together is fine, but using audioplayer is out of sync. What's the better way to get good sync?
