This is a recording of a keurig coffeemaker brewing a 6 oz. Cup of coffee in a mug. The clip begins with the closing of the door over the brew-pod container. The coffeemaker's pump cycles 43 times for the brewing of a 6 oz cup, and then refills and reheats the internal reservoir.
I set my zoom h4n on my kitchen counter, turned the record volume up to 100%, and walked out of the room. There's slight noise from the window and my refrigerator.
This was recorded in my kitchen by rubbing fingers on the cooktop of my stove, on a zoom portable recorder. This file is the original recording without any edits.
