This is an eerie sound made from recording my breathing with a whistle in my nose and then slowing it down and altering it quite a bit. Recorded and edited using audacity.
Two small mechanical sirens recorded with a h2 recorder in a factory building. One siren is very close, the other in a remote place. You can also hear the sound of a door and ambient noise.
