The microphone was placed inside a stainless steel metal box and placed in my shower. The shower rains onto the box and creates a rich, metallic resonance.
Rhythmic hammering on a metallic tool box with a scabbling pick (hammer). Four different styles - first mixed with some scratching sounds, then hammering in three rates of speed. Recorded on zoom h2.
Accidentally, dropped a metallic rod onto my wooden table while trying to record some audio with it. My mistake is your gain. Recorded on a blue yeti microphone through audacity at 16bit 44000hz. Attribution appreciated but not required.
Me shaking and turning a small cardboard box, mostly empty but still containing some nails and other metal bits. Recorded at my deskslightly edited to reduce background noise.
