The audio titled "Door Knock" is a carefully crafted sound design piece that effectively brings to life the auditory experience of a knock on a door. The sound begins with a clear, resonant knock that echoes a sense of anticipation. This knock isn't harsh or abrupt, but rather has a rhythmic and almost melodic quality to it. It's a sound that one might associate with a cartoon, where it would be used to enhance a scene's humorous or dramatic effect. The knock is repeated a few times, each hit of the door reverberating with a distinct timber, creating a multi-layered auditory experience. The sound effect ends with a soft fade, leaving a lingering sense of expectation and curiosity.
