The line 'Beim nächsten Ton ist es' comes from the world of German speaking clocks, the old telephone time services where a calm voice announced 'at the next tone, the time will be' followed by a buzzer tone. The clip captures only the lead-in, which is exactly why meme makers love it: the missing time turns a dull utility announcement into a tiny cliffhanger. It now circulates on soundboards and short-form video as a tongue-in-cheek countdown, usually cut right before a reveal, a punchline or an anticlimax.
