At just over two seconds, the MP3 is compact enough for quick reactions and usually needs no trimming. Download it once to keep it available offline, then assign it as a ringtone or short notification tone if your device allows custom audio. Its sharp upper range can cut through speech, so lower it when dialogue is already bright or loud. For a mini scare sequence, place a door knock before the laugh or follow it with a dramatic sting, leaving enough space for each hit to register.
