I recorded myself using a hand-grinder to grind come coffee beans, but it works for nearly any sort of grinding sound. Good for videos with machines and such.
Ive played this metalbox near my house at a church. Its like a square metallamp with no lightbulb in it, and recorded from the inside with a r-09. Processed in logic. Eastjutland, holme, århus, denmark.
Recorded using only an android phone and 'recording machine' app. The recording was made on the metal jetty at london greenwich a minute or so after the ferry had departed. The sound is of the metal plates of the walkway rubbing together as the jetty gently rises and falls on the swell. Eerie and atmospheric. Strangely quiet considering it was recorded in a major city.
Recording of myself playing a home-made instrument constructed from a large suspended metal door affixed with bits of thin aluminum sheeting of varying sizes and bent at varying angles. I "played" this by striking and plucking the bits of aluminum and recording the results through a piezo contact mic adhered to the door.
Sounds of an ordinary kettle being used in a manner similar to a water gong: struck and then the sound of the resulting clang being modulated by the moving water inside.
Slightly resonant clanging and pinging of me hitting the metal stairs of a reviewing stand used in a local parade. The mic is held very close to the surface, so there is very little environmental noise.
