Whirlpool cabrio washing machine in final stage of spin cycle to remove water from laundry. A consistent hum with regular pulse of a quiet rattle. A nearly soothing machine noise.
Couldn't quite find exactly the sound i was looking for so i made it myself. It's intended to sound like a revolver spin for a video game special move, including a little handling noise at the end. Ratchet recorded with rode ntg4+.
A recording of my car wheel spinning on gravel in a local car park at night. Recorded using a tascam dr100 portable recorder and a behringer c4 condenser microphone.
