Place this clip at the cut where a file, name or screenshot gets hidden in your edit. Follow it with a censor beep when spoken words need covering, or precede it with dun dun dun when you want the reveal to build before the shutdown.
このサウンドについて
This is a very short 0.5-second sound effect built around the idea of something marked classified. It plays as a quick secret-file sting rather than speech or music. Hearing it gives a tense, secretive feeling, like a document has just been stamped, redacted or locked away, which makes an ordinary reveal feel suddenly restricted and important.
