The clip runs about 11 seconds, giving the whistle enough room to establish its rhythm without requiring a loop. Download the MP3 to keep it available offline, then trim only if you need a shorter notification tone. The complete file also works as a ringtone because its melody is easy to notice without a sharp impact. When layering it over dialogue, lower the whistle enough to preserve speech clarity. For a longer comedy sequence, follow it with Goofy Ahh Sounds rather than stacking both tracks at once.
