Place it as the final beat of a short scene, right after the last line lands and before the screen cuts away. Follow it with Mission Failed to underline a plan falling apart, or use Ba Dum Tss just before it when the hang-up is the punchline to a bad joke.
关于此声音
This 1.9-second clip is a short call-ended tone, the kind of flat hang-up signal heard when a phone line drops. It feels abrupt and final, with a dry, slightly awkward edge that makes a cut-off feel deliberate rather than accidental. It lands best as a quick, recognisable ending for a conversation that has run its course.
