A siren alarm being tested, recorded at the bottom of the building. Noises of a marketplace in the background : some affect lightly the sound of the alarm, but they are mostly very low sound you could get rid off with a low pass filter. Two other recording of the same alarm exists : far and muffled. See the pack for more information. Recorded with Eagletone CM60 and Focusrite Solo 2ndGen, edited in Reaper.
