The guest room i am staying in has a tile bathroom. Each time i take a shower, i hear this magnificent hum of the water heater clicking on and then turning off once the shower water is stopped. I was fortunate enough to hear it click on while i wasn't in the shower and captured about 30 seconds of it before it died. Infinite variation, impossible to replicate. At the end, as the water heater shuts down, it clicks down into the lowest ranges of the frequency spectrum; i didn't hear it until i listened to the recording but the couple of seconds of that are just as magical. Wish i would have left the recorder running!. Captured with a zoom h3-vr to ambix format at 96k24bit and bounced to stereo. Processing: 24db gain to all 4 clips, izotope spectral denoise to get rid of the air in the room and izotope ozone to enhance the bass signal a touch. Enjoy!.
