The clip runs for about 11.7 seconds, giving the automated warning enough time to build tension without requiring a long setup. Download the MP3 to keep it available offline or import it into an editing app or soundboard. It can also be assigned as a ringtone or notification tone if your device accepts custom audio. Trim the beginning only when you need a faster cue. Over music, lower busy midrange elements so the voice stays understandable, and avoid layering dialogue across the main announcement.
