Read MoreClose your eyes. The lights flicker. A low growl cuts through the silence… familiar, but not quite human. Before the creature even appears, your heartbeat quickens.
Sound is often the first storyteller in horror. Long before we see what’s coming, we hear it. And that’s exactly why sound design is one of the most powerful tools in cinematic fear.
As Halloween approaches, we’re looking at why scary sounds work on us, how horror audio has evolved over the decades, and how Dehumaniser 2 gives today’s creators the same terrifying power once reserved for big studios.
Our brains are wired to respond to certain sounds; sudden volume shifts, distorted human tones, sub-bass vibrations. These frequencies trigger primal instincts tied to survival: danger, threat, the unknown.
Classic monster movies relied on this psychology long before sophisticated software existed. Filmmakers would pitch-shift growls from lions or tigers, layer them with distorted human screams, and loop them until the sound became something unrecognisable, and something that felt alive.
That uncanny, half-human quality is key to why certain sounds are terrifying. When something almost sounds human, but not quite, our brains panic. And this is where Dehumaniser 2 comes in.
From Tape to Tech: The Evolution of Horror SoundIn the early days, creating monster voices was a time-consuming art. Designers cut tape, slowed reels, and layered multiple recordings manually. As digital tools emerged, the process became faster but still relied on complex plugin chains.
Then came Dehumaniser 2, a breakthrough in real-time creature and vocal processing.
Built by sound designers for sound designers, Dehumaniser 2 offers an intuitive, modular workflow that lets you transform any voice into something otherworldly in real time. Whether you’re making a cinematic demon, alien overlord, or supernatural whisper, the results are instant, believable, and deeply unsettling.
Inside the Monster Machine: How Dehumaniser 2 WorksDehumaniser 2’s power lies in its modular, node-based design. Instead of stacking endless effects, you connect modules like puzzle pieces, each shaping the voice in unique ways.
You can trigger real animal recordings – tiger, leopard, pig, and more – by amplitude or pitch, creating layered vocal hybrids that feel alive.
Every adjustment happens in real time, meaning performers can act their creatures live. What once took hours of layering and rendering now takes minutes.
When Humans Become MonstersThe most frightening creature sounds often begin with something deeply human. Take a whisper, a scream, or a breath, then distort, layer, and stretch it until it sits somewhere between familiar and alien.
That’s exactly what Dehumaniser 2 does best. Start with a simple vocal. Drop in an “Angry Beast” or “Spectral Demon” preset. Add pitch-shifting and convolution layers, and suddenly your voice carries the weight of something unholy.
You’re not editing fear. You’re performing it.
Dehumaniser 2 in the WildThe power of Dehumaniser 2 has already shaped some of the biggest universes in film, TV, and games – from Avengers: Age of Ultron and The Jungle Book, to Far Cry 4, The Conjuring, and Stranger Things.
When sound teams need something fast, flexible, and believable, they turn to Krotos. What used to take 20 layers of samples and hours and hours of work can now be done live in a single voice pass.
Create Your Own Horror TonightHere’s a quick Halloween experiment you can try in your home studio or DAW:
Press play.
Now you’ve got a fully cinematic, spine-chilling sound in minutes, ready for a short film, game, or Halloween post.
The Future of FearAs AI and real-time audio evolve, horror sound design will only grow more immersive. We’ll see dynamic creature voices that respond to player movement, and vocal morphing that adapts live in film or VR.
But even with all that innovation, the essence stays the same: we’re still playing with what the human ear almost recognises. That’s why Dehumaniser 2 is so powerful – it bridges human and inhuman in one tool.
Krotos continues to lead that frontier, helping creators turn sound into storytelling.
In horror, silence may build tension, but sound delivers the fear. From 1930s monsters to modern AI-powered creatures, the tools have changed, but the goal remains the same: to make us believe in the things we can’t see.
This Halloween, explore that line yourself. Twist your voice. Break the silence.
Start your free 10-day trial of Dehumaniser 2 and bring your monsters to life.

Read MoreThe fifth and final season of Stranger Things will be released on Netflix in three parts: two volumes on November 26 and December 25, 2025, and the finale on December 31, 2025.
With build up to the the show being one of the most anticipated Netflix releases of the year, what better time to look back at it’s retro-nostalgic, yet modern and cinematic, sound design.
Drawing from our interviews with Angelo Palazzo, who worked on Stranger Things 3, we unpack the magic behind these iconic sound effects, and offer some exclusive tips for you to know when making your own iconic sci fi sound effects.
What makes Stranger Things sound design so distinctive?From the start, Stranger Things has stood out not just for its visual homage to the 1980s, but for a soundscape that blends retro sonic textures with horror/fantasy tension. As seasons progressed, the show pushed harder into immersive creature design, atmospheric ambiences, and visceral audio moments.
By Season 3, the Stranger Things team decided early on that we weren’t going to use any of the SFX or backgrounds from the first two seasons and instead built Season 3 entirely from the ground up.
Moreover, for Season 4 the sound-design crew intentionally went “more aggressive, more greedy, abrasive, and disturbing” to match the darker tone of the story. The result: a show that sounds cinematic, expansive, and uniquely its own.
How the Stranger Things sound was craftedOne of the reasons Stranger Things’ sound design is so memorable is the team’s inventive use of everyday materials, creatively processed to build its eerie atmosphere.
For the creature vocals, like those heard from the Demogorgon and other monsters— Dehumaniser and Reformer Pro come in handy for transform human voices into otherworldly textures:
With Dehumaniser, I can process my voice and get much closer to a final result.”
To capture the unsettling movements of Vecna, season four’s sinewy nightmare of a villain, the team recorded fibrous vegetables including carrots, celery, and cabbages to create a “wet, slimy” sense of twisting vines and tendons.
Palazzo noted that he prefers to “start with the most organic sounds” before tweaking, pitching, and layering them into something unrecognisable. Even household items found their place in the Upside Down: sliding closet doors, squeaky hinges, bending wood, and scraping cardboard were all reimagined into aggressive, creature-like sounds.
The result proves that true sonic creativity begins with the familiar—then stretches, distorts, and layers it into something entirely new.
“Reformer Pro is my go-to-tool for quickly creating new fx layers … Dehumaniser allows me to create very usable tracks that will typically end up in my final build.”
