Sonaris
Location-aware sound · Since 2031 · 14 worlds

Sound that knows where you are.

Sonaris makes audio that plays at the right place, on any world. Habitat walks that narrate themselves at 30 metres. Domes that change their acoustics in a single gesture.

Three products, one idea

Put sound where it belongs.

Every Sonaris product starts from the same question: what should someone hear, right here, right now? For a colonist on her first walk it is the story of the dome ahead. For a cathedral under the ice it is the shape of the next chord.

Press start. Then forget your visor.

This is the real trigger logic, running in your browser. The walker follows the Tharsis Ring corridor with a Murmur flying just ahead. When the MPS position falls inside a stop's circle, and the fix is accurate enough, the story plays. Stops reached at the same time wait their turn.

Audio starts by itself when you reach a stop. The display can go dark to save power; the trail keeps listening.

Aeolis · playable

Tune a whole dome with one scene.

Aeolis treats a room like an instrument. Every stop adds a layer, from deep Nebula foundations to bright Starfield shimmer. Save combinations as lettered scenes, the way organists have marked their scores for five centuries. Choose a scene, pull a stop, play a key.

Scene
Hymn for Low Gravity, Op. 9 · Europa Ice Cathedral · choose a scene
No stops drawn. Pull a stop, then play.
Keys A to K on your keyboard also play

A room is the biggest instrument you own.

Under the ice of Europa, sound travels strangely. Aeolis drives 4,000 resonators in the walls, so a choir of twelve can sound like a hundred, and a whisper reaches the back row.

  • Scenes and sub-scenesA, B, B1, C. With movement and bar, so you know exactly where the change falls.
  • Per piece, per hallThe same hymn needs other stops in a lunar chapel than under 11 km of ice.
  • Stop numbers leadThe same numbers as in the score, on every console.
  • Synced across consolesPrepare at home, play in the cathedral. Nothing overwrites anything.
From idea to trail

Live in four steps. On any world.

You build the trail yourself. If you would rather have our field crew do it, they travel.

Step 1

Request access

You get one start page with everything in one place. One link to keep.

Step 2

Map the route

Import a habitat plan or an orbital scan, then click to place each stop.

Step 3

Add a voice

Type the story, pick a voice, generate. Or record your own in the airlock.

Step 4

Share it

One trail link and a code. Put it on a hatch, a flyer or a Murmur node.

Lead · 3 m aheadØ 140 mm · tilt to inspect
Murmur · hardware

A guide that flies ahead.

A Murmur is a small flying speaker. It waits at the start of the trail, and when you set off it lifts to eye height and stays a few metres in front of you. The story comes from where you are heading, so you simply follow the sound. Stop to look around and it waits. Take a wrong turn and it comes back for you.

Murmur · voices

Hear what a Murmur sounds like.

A Murmur speaks in the voice the trail maker chose. There are 48, from Earth Dutch to Lunar Creole. Type the story for each stop, pick a voice, and spell a crater name the way it sounds if it comes out wrong.

Tap a voice to hear it. Tap again to stop.

Hans Latour

How Sonaris began

Hans Latour started Sonaris in 2031, on the water. He had spent a career on dry land, in recreation, websites and booking systems. When the polders around 's-Hertogenbosch flooded for good, the old cycling routes became boat routes, and nobody knew what they were floating over. Hans put the stories back where the villages had been.

The idea travelled. First to the Moon, where the crater walks needed a guide who never got tired. Then to Mars, where his team learned that 30 metres is the right radius in any gravity.

Hans Latour playing the organ of the Sint-Jan in 's-Hertogenbosch, a tablet on the music desk
At the Sint-Jan organ in 's-Hertogenbosch. The tablet on the music desk ran the first version of what became Aeolis.

Aeolis came from the organ bench. Hans was tired of pencilling stop numbers into the margins of his scores, so he wrote an app that remembered them for him. Sixty years later its descendant tunes a cathedral under the ice of Europa.
