The end of the protective tube for my microphone being turned and producing a not so nice, rusty sounding, squeak. Part of my squeaks pack. Recorded with a rode ntg-3, through a sqn 4s, into a zoom h4.
The squeaking of rubber fenders squashed between the hull of a cruise liner and the dock wall. The sound of the ship's metal gangplank groaning as it rubs against the quay is in the background.
Found an old abandoned truck on a hike - recorded the squeaking and creaking of the doors opening and closing and stressing different parts of the metal. (it was done outdoors, so there may be some birds).
