The original sound was the hot water heater and the water level valve discharging in my furnace room.

I then used Ableton live "Grain Scanner" to generate 9 samples from this ambient sample,

then using (FX) reverb, resonator, rig modulation, delay and pitch shift

i mix and merged then in to the soundscape ,

finally all post processing was done in audacity

(fade in fade out and general normalizing and compression)
