SmartSound's Quicktracks technology is the driving force behind the MagicMusic feature inside CyberLink PowerDirector 4. This patented technology allows users to create soundtracks for their projects through SmartSound's "block" method. Users select a song from SmartSound's royalty-free music library and bring it into the timeline. The song is automatically rearranged into a complete soundtrack piece with a musical beginning and ending, that matches up with the on-screen visuals.

These songs can fit any length needed, from a few seconds to several minutes, according to SmartSound.
