At just over seven seconds, the clip is long enough to use whole or trim after the strongest cackle. Its bright, sharp voice can cut through music, so lower it when dialogue is already loud. Download the MP3 to keep it available offline, then assign the file as a ringtone or notification tone if your phone supports custom audio. For a reaction sequence, place an evil laugh before it or a Ba Dum Tss drum sting afterward, but avoid stacking several loud effects over the cackle.
