We came across an abandoned village near Chiang Mai, Thailand and one of the villas had two amazing metal door knockers. The house was empty inside so it created a natural reverb by knocking on the old wood door.
I recorded both knockers several times.
I also removed from different tracks the background noise and as a bonus, I added more reverb to other recordings as well.
