Ghost sound, could be used for a die sound, ambience, etc.
Nice. I might use this for a new "crit-death" animation of my Skeletons
I'm using this for my Glest mod. It's the sound of a magical portal opening.
Used your sound in my new game, Regret
I used this for my sample game with my blog post on iOS 7 Sprite Kit: http://www.captechconsulting.com/blog/mark-digiovanni/ios-7-tutorial-ser.... I link to it as well.
