Listen to be transported into Hugh Howey’s world of Wool. These sounds emulate a multi-level society that survives underground in a giant vertical silo, all floors connected by one spiraling metal staircase.
Behind the Scenes
I knew the silo would be an interesting choice because of the metal, its vertical layout, and its spacious, round acoustics. With those acoustics in mind, I slapped plenty of reverb on every sound, and knowing the layout was vertical meant we could experience two or three floors perceived through audio. The sound of climbing the staircase as a sort of anchor because it is present throughout every floor.
I grabbed sounds from freesound.org as well as from YouTube using the free 4K Video Downloader software. From there, I layered my different audio samples to try and tell the story of a person ascending/descending the staircase for a short time.
Fading audio in and out gradually gave us the illusion of movement throughout the silo. You can hear children, talking, another person passing on the steps, an intercom announcement (which I made following this tutorial, plus reverb), construction, and the constant moan of the metal staircase alongside our host’s footsteps.
