Refri Noises

MY refrigerator was annoying me with its noises. There is a small ventilaro producing erratic metallic sounds.
There is also de 60 hz of the electical power. After several days decided to get constructive.
I sampled the sound and used Vital vst to dictate some FM synthesis out of a sine wave.
}I also added a third oscilator with a saw wave to add some color. I processed everything in the stero field
And the result was very interesting. I wanted to also make a pluck of this sound. At the end the basic form is 55 hertz of electricity
two oscillators and the rest created chaotic harmonics
