Audio Clip: Single Police Siren (Courtesy of Audio-Cutter.com)

This audio clip features the distinct, unmistakable sound of a single police siren. It's a special effect audio that has a looping quality, meaning that the siren's wailing noise continuously repeats without any interruption. The siren alternates between a high and low pitch, creating an urgent and attention-grabbing effect that is commonly associated with emergency situations. This sound effect is typical of what you might hear in urban environments, during a police chase, or in scenes of crime and emergency in films or video games.
