About the piece:
This soundtrack consists of a collection of sounds. The main, haunted soundscape that spans the entire track is created by a sound generator called Space Drone, developed by Native Instruments. The sounds are created by a range of pitches spanning the human audible spectrum from 20 hertz to 20 kilohertz. These pitches are modulated so that they are performed at randomized attack speeds and volumes. Attack speeds determine how long it takes for the sound to reach its full volume, and volume simply determines what that maximum loudness is. By altering the pitches as well as the number of pitches that rise and fall at similar times, the sounds generated can range from subtle to intense, from a low growl to a piercing roar.
