Here is a recording i made of my toilet flushing. I used 3 microphones, one placed in the bowl, one place on the cistern and one placed about 2 feet away from the toilet. The mics were fed into a sound devices 664. The only post processing i did was mix the levels. Toilet bowl - shure sm57cistern - sanken cos11main mic - sennheiser mkh416.
