This is an audio recording titled "Sound of a Grunting Mask". As the audio starts, the first thing that hits is the palpable sound of a mask, a hollow, muffled resonance that speaks of concealment and mystery. Amidst the masked silence, there suddenly erupts a low, guttural grunt. It is a sound that transcends words, communicating a sense of raw pain and agony. The grunting continues, each one sounding more strained than the last, as if the wearer of the mask is undergoing unbearable torment. The grunts grow louder, more desperate, till they eventually fade, leaving behind an unsettling echo that resonates within the confines of the mask. The audio ends, leaving a chilling aftertaste of hidden suffering, a silent scream behind the facade.
