I cannot remember what kind of motor i recorded, as i did this recording in 2013. Its recorded with a h4n somewhere in the city centre of london (uk) and i used it previously for car sounds.
Zoom h6 stereo mic pressed up against window being pelted by heavy rain in suburban area. Sound of overflowing gutters then as rain dies, distant sound of thunder and ticking of clock revealed.
The sound of a water bottle being squeezed repeatedly (a great value walmart brand water bottle to be specific). Recorded with a zoom h1 in 24/96 pcm. The. Wav file has not been modified and is straight from the h1 recorder.
