Referee Whistle & Buzzer

Sounds

• Short Whistle - A quick high-pitched tweet. Use it to stop play, indicate a foul, or signal a throw-in.
• Long Whistle - A sustained blast. Use it to mark the end of a period or the final whistle of the game.
• Double Whistle - Two short tweets in rapid succession. Common signal for a foul or penalty in many sports.
• Buzzer - The classic end-of-period electronic tone heard in basketball and hockey arenas.
• Air Horn - A loud, sustained blast synthesised to mimic compressed-air horns used at football and rugby matches.
• Alarm - A rapid repeating beep for urgent situations such as a safety timeout or equipment issue.

Volume

• Use the volume slider at the top to set the output level before pressing a button.
• For the loudest effect on mobile, set your device volume to maximum and the slider to 100%.
