At 12.8 seconds, the clip provides enough whistle to sustain a tension gag without looping. Download the MP3 for offline playback, then trim a shorter burst if a full-length ringtone feels too persistent. Most phones can assign the saved file through ringtone or notification settings, although the exact menu varies by device. Lower it beneath dialogue because the piercing tone can mask speech and other high frequencies. For a stronger ending, keep a Vine Boom ready after the whistle cuts off.
