In this audio recording, titled "Sound Recording 1: Knocking on Glass", the primary sound you will hear is a rhythmic tapping on a hard surface. This sound is reminiscent of a foley artist at work, using their skills to replicate everyday sounds for use in multimedia. The tapping is measured, deliberate, and is reminiscent of a fingertip or a small object striking a pane of glass. The sound has a unique timbre, an echo that denotes the specific material being struck is indeed glass. It's a clear, sharp sound that reverberates slightly, giving the listener a clear understanding of what they're hearing. The glass does not break or shatter; instead, it endures each tap, each knock, creating a rhythmic pattern that carries throughout the recording. The knocking is neither too harsh nor too soft, expertly balanced to replicate a common, real-world sound. This is an embodiment of the tag "mus152", demonstrating a keen understanding of sound production and manipulation
