Warning: this sound is just a little loud. A spooky noise i made for a map for garry's mod. You might be able to deduce that i'm making a horror map. If you want more freaky noises like these, (i may question your sanity) but i'll make one for ya. ;).
Recreation of the tone used in the score john carpenter's the thing by ennio morricone with a loopable mix of singles doubles and triplets for more variety.
