The audio track titled "Making a Squeaking Sound" begins with the sound of a marker being uncapped. This is followed by a high-pitched, rhythmic squeaking sound that reverberates gently, creating a unique sound effect. The source of the sound is the marker being moved back and forth on a surface, its friction generating the distinctive squeaking noise. This effect is repeated several times, each time with a slightly different intensity and speed, providing a variation in the squeaking sound. The audio ends with the sound of the marker being capped again, bringing the audio full circle. The entire experience provides a rich and immersive sound effect that captures the essence of a marker making a squeaking sound.
