This audio file, titled "071678_Bolt.wav," is a sound effects recording. The focus of this audio is on the distinct, mechanical sound of a bolt. The sound effect begins with the resonating metallic clatter of a bolt being released or moved, followed by the subsequent sounds of it sliding through a metal fixture. This could symbolize the unlocking or locking of a door, or the operations of a complex machinery. The echoey nature of the sound suggests it's taking place within an enclosed or semi-enclosed space. There's a slight reverberation that hints at the hardness and solidity of the materials involved. The action is swift, precise, and carries a sense of finality, often associated with this type of sound effect.
