This sound is meant to be used as a tension builder for films or video games, and/or as background noise to create a scary atmosphere.
Very eerie horror ambience this one, it has plenty of dark drones and distorted screams, to make them sound like ghosts or ghouls. (This is one of my favorite horror ambiences. )
Can be used for films and videogames, it loops seamlessly. (use the wav. file)
