This is percussion in an empty swimming pool in essen, germany. The empty pool gives it a natural 3-time delay. Recorded with a grundig tape-recorder about 1987. Today (in 2018) the swimming-pool is filled up with sand and is part of a beach-bar.
Recording of pond sounds in april. There are multiple creatures making sounds here - however, it is not purely nature sounds - there is a highway about a mile away and some of that drone is evident in the background. The foreground however is strong enough that it should be useful for basic nature ambient sound.
