The Pei Xin clip is listed under the Japanese and Chinese word for broadcast or streaming, which explains why creators reach for it when a video needs a live-announcement feel. With a running time of under three seconds, it fits the fast rhythm of short-form edits, where a sound must register instantly and then get out of the way. Its small footprint on soundboard sites has kept it niche, but that brevity is also its appeal: it is easy to drop into montages, stream highlights and reaction edits without changing the pacing of the surrounding footage.
