The Sound effects module is an even simpler music player, designed to play very short sounds such as gunshot, scream, etc. Unlike the Music module, there is only a tree; to play a sound, just double-click on a sound item. A sound can be played while music is playing in the Music module. But if a sound is played before another one is finished, the second one will replace the first one. There is no way to stop a sound before its natural end.
