The dark art of using audio to make players terrified of what they can hear but can't see.
Horror sound design is a specialized discipline that weaponizes every audio technique in the book to create fear. It exploits the fact that humans are hardwired to fear what they hear but cannot see -- a distant scraping, a child's laugh in an empty building, breathing that isn't yours. Techniques include infrasound (frequencies below 20Hz that cause physical unease), spectral gaps (removing expected frequencies to create wrongness), dynamic silence (stripping audio to make the next sound a jump scare), non-linear sounds (distorted, unpredictable tones that trigger the brain's alarm system), and spatial disorientation (placing sounds where they shouldn't be). The best horror audio makes you dread pressing forward before anything has even happened.
Example
Silent Hill 2's sound designer Akira Yamaoka used industrial noise, radio static, and distorted metallic scraping to create an audio landscape of pure psychological dread. In Amnesia: The Dark Descent, the sanity system alters audio processing as your character loses their grip on reality -- sounds distort, phantom noises appear, and the environment itself seems to breathe.
Why it matters
Horror is the genre where audio does the heaviest lifting. You can close your eyes in a horror game, but you can't close your ears. The best horror sound design proves that audio is more powerful than visuals for creating fear, and the techniques developed in horror games advance the entire field of interactive audio.
