(recorder: zoomh4npro 2018)(microphones: roland binaural earbuds / microphones). A recording of pool equipment operating to filter water and supply a hot tub. This seems to be a great sound for any engine-room. This audio may be applicable in many situations. Enjoy!. - christopher.
A sample of the hose and resulting pressure build up from a level controlled pool float. The impedance of the flow is what causes the resulting sound. Recorded with a zoom h4n field recorder.
Plenty of birds singing in an urban environment before anyone else wakes up. There is a very faint background hum from the pool pumps. A few miles from murcia city, murcia, spain. Recorded on a zoom h1 with internal mics.
