Frame
Space
The acoustic frame of a world: reverberation, room character, and how far outside your head the sound appears — tight and dry, or wide and resonant.
What is Worlds
Compose sound environments. Walk through them.
Composers build walkable 3D sound worlds — you walk through them in your browser, with headphones. There is no fixed listening position and no fixed duration: your path is the piece.
What a world is made of
Every world is built from four elements.
Point
Sources
Sound sources with plausible distance and directivity — radiating 360° or in a focused cone, like a loudspeaker.
Area
Zones
Sound beds that fill a region. Enter and the sound fades in; leave and it fades out. Zones can overlap; a set priority decides which one you hear.
Trigger
World Objects
Visible or invisible triggers: approach one and a sound starts, a text appears, a change unfolds.
In the browser
Built in the browser. Nothing to install.
Rooms
From a simple box to a 360° photo of a real courtyard.
Start with a neutral geometric space, upload your own 3D model, or use a 360° photo as a photorealistic backdrop — recreate a real place, or build one that couldn't exist.
Perspectives
Step inside your own composition — at any moment.
Bird's-eye view for placement, third-person for overview, first-person to walk through as visitors will. In explore mode the tools disappear and only the world remains.
Mixer & sync
A mixing desk for space instead of a timeline.
Every source, zone and world object gets its own channel with mute, solo, level and reverb send. Sync sources to a shared clock, so a multichannel piece plays as one coherent work.
What Worlds is for
A tool and a stage.
01
Preserve walk-through installations.
You don't record a walk-through installation — you rebuild it.
Free position and duration stay intact — the work remains walkable online long after the exhibition closes.
02
Build what physical space can't hold.
Vast rooms, dozens of simultaneous sources, impossible architectures — a venue that exists only online.
03
Plan installations before they exist.
Recreate the courtyard, gallery or hall where a work will stand and hear it on screen before a single loudspeaker is placed.
8–11 October 2026 · Volkskundemuseum Graz
Three worlds left the screen and became a walkable installation.
Visitors walked the museum courtyard with headphones, tracked in space, hearing the sound change with every step and every turn of the head.

Frequently asked questions.
What do I need?
Headphones and a current browser. Worlds works on desktop, phone and tablet: on a computer you move with WASD, on a phone or tablet with an on-screen joystick. Nothing to install.
Who can use Worlds?
Anyone can walk through the published worlds — no account needed. Building your own world is opening in stages: we're onboarding composers, curators and institutions step by step via the waitlist. Tell us who you are and what you'd like to build.
Do I need audio software or coding skills?
No. Worlds runs entirely in the browser — nothing to install, no code to write. You place sounds in 3D space by dragging them where they belong; the complexity of spatial audio and binaural rendering stays beneath the surface.
How does the spatial audio work?
Worlds is built on the web audio engine by atmoky, a Graz-based company with roots at the Institute of Electronic Music and Acoustics (IEM). It renders binaurally in the browser: sources stay anchored as you move and turn, and loudness falls off plausibly with distance.
Can Worlds be used for physical installations?
Yes. In October 2026 three worlds built with Worlds became a walkable headphone installation in the courtyard of the Volkskundemuseum Graz, with visitors tracked in the space. If your institution is interested in a similar project, get in touch via the waitlist.
