Place it at the start of a transition, just before the new time, date, or schedule appears, then follow it with a buzzer when the deadline passes and a cheer when the plan finally lands.
About this sound
This just-over-ten-second clip is a Brazilian radio announcer giving the hora certa time check, naming Jovem Pan in a clear, brisk station-ident voice. It feels official and a little comic, like a newsroom pause that makes a moment feel timed and deliberate. It comes from that network, one of Brazil's best-known news and talk radio stations.
