The exact source of this clip is not clearly identified from the available details, so it is best treated as a generic Morse code meme sound rather than a confirmed movie quote or soundtrack excerpt. Online, sounds like this spread through short edits, puzzle content and mystery posts because the pattern of beeps immediately signals secrecy and decoding. Its appeal is simple: even without words, audiences recognize the coded message idea right away, making it useful for suspense, investigation jokes and cryptic transitions.
