A 1970s television set whose channels are rooms. Footsteps, knocks, door creaks, drags, whispers and breaths are synthesised from oscillators and filtered noise - never sampled, so they never repeat - and placed around your head with HRTF binaural panning inside a procedurally generated room reverb.
Turning the dial changes the room, its dimensions and its reverb, hidden behind a burst of static. You can turn your head by dragging the screen. Headphones are strongly recommended: binaural direction cues collapse on speakers.
Eight channels cover a hallway, an upper landing, a cellar, an empty room, close quarters, a stairwell and the far side of a door. Each carries its own dimensions, reverb character and set of likely events, and the activity control changes how often the room does something without turning it into a drum machine.
Audio filtered the way your head and ears filter real sound, using head-related transfer functions (HRTFs). Small differences in timing and tone between the ears tell your brain where a sound is — including behind and above you.
Speakers mix the left and right channels in the air before they reach your ears, which destroys the cues. On speakers the sounds are still there, but not their direction.
No. Every footstep, knock, creak, drag, whisper and breath is synthesised from oscillators and filtered noise, which is why no two are the same.
Ambient horror soundscapes, tabletop and live-action games, sleep-averse listening, or as a reference for how much direction and room size change the effect of a sound.
