KeokeN Interactive’s audio director, Sander van Zanten, revealed the challenges behind creating realistic, engaging sounds within the vacuum of space in Deliver Us The Moon.
In an interview with Prankster101, van Zanten stated the main challenge the limitations of creating sounds because he could not use air as a medium for sound to travel through. Therefore, he focused exclusively on low frequency sounds, like vibrations, to deliver a realistic acoustic experience.
“The interesting thing about sound in space is that indeed, there is no sound that’s being carried by air. So there’s no air for sound to vibrate in. But there is your body, and vibrations in your body can also cause a sound, so if you were to hit yourself with your ears closed, you would actually hear that. You would hear the impact.”
The studio developed technology to filter out higher frequencies, inspired by how the human body can absorb energy and transfer it into low frequency sounds.
“We’ve tried to emulate that kind of impact by means of a filter, its basically a filter that goes over all the audio in order to get out all of the higher end frequencies and only preserve the low end frequencies when you’re in areas that have no oxygen in them.”
van Zanten continued, “It’s taken a lot of experimentation and trial-and-error […]but we’ve now come at a point where it feels convincing and compelling so you don’t hear things that are far away, because there is no air to carry the sound from the source to you. You only hear the things that are close to you and the sounds that they make, you only hear the really low layers from them. So it feels very physical, the sound.”
Deliver Us The Moon is a sci-fi thriller set in a dystopian near future where Earth’s natural resources have been depleted. The World Space Agency has secured a promising new source of energy on the moon. However, the colony suddenly falls silent and the energy source is lost.
OnlySP’s Amy Campbell previewed the game last month, saying “KeokeN Interactive has crafted a game with visual polish and narrative excellence that deserves a place in a story lover’s gaming library.”
Deliver Us the Moon including the ‘Fortuna’ and ‘Tombaugh’ expansions will release for PC, PlayStation 4, and Xbox One on October 10, 2019.
