Under the hood

How Stagefront Works

A browser-native 3D venue. Screenshare as your stage. Spatial audio that responds to where fans stand. Here's the full picture.

The Core Technology

The venue is a browser room

Stagefront shows happen inside Portals — a spatial 3D engine that runs entirely in Chrome with no download, no install, no account. Every Stagefront artist gets a custom Portals room as their permanent stage.

These rooms are real 3D spaces — not video chat grids, not flat stream embeds. Fans enter as avatars and move through the space. The room has a stage, a floor, walls, interactive objects, and a crowd that's physically present.

Venues are auto-generated via the Portals Rooms API when an artist is approved. Every detail — stage layout, lighting, billboard content, spatial audio zones — is configured to the artist's spec.

Screenshare is the stage

Artists don't stream to a platform. They screenshare into their venue. Whatever is on their Chrome tab — a DAW producing live, a camera, a full visual set — appears on the stage screen inside the 3D room.

The key difference: the audio from the screenshare feeds into the venue's spatial audio system. It's not piped to all fans equally. It behaves like sound in a room — louder near the stage, quieter further back.

Fan experiences it like standing in a venue — walk to the front and the mix hits you. Step to the back and you hear the crowd more than the stage.

Spatial audio that
responds to position

Every sound source in a Portals room has a falloff distance — a start radius (full volume) and an end radius (silence). Between those two points, volume fades linearly.

For a Stagefront show, the stage screen is the primary sound source. Artists can configure the acoustic feel of their venue — a tight club will have a short falloff (you need to be close). A festival stage radiates across the whole field.

Fan voice comms work the same way. Side conversations don't bleed into the main stage audio. VIP zones can have their own ambient audio. The space sounds like a space.

How artists run a show

End-to-end — from application to curtain call.

01
📋

Apply & get approved

Fill out the artist application — genre, audience size, what kind of show you want to run. We review every application personally. Founding artists get priority.

We're keeping the founding cohort small so each artist gets real attention from us during setup.

02
🏗️

Your venue is built for you

We provision a custom Portals room as your stage. It's branded with your name, your colors, your identity. You get a permanent venue URL that's yours to perform in indefinitely.

Powered by the Portals Rooms API — your venue is auto-generated from your artist profile. Custom GLB stage assets, billboards with your set list, merch display in the corner.

03
🎚️

Set up your performance

Walk into your venue. Configure your stage: set the screenshare area (where your feed appears), calibrate the spatial audio falloff, set the mood lighting.

No code required. The Portals interactive studio handles it through a point-and-click in-venue interface.

04
🔗

Invite your audience

Share your show link. Fans click it and walk in. You see the room fill in real time. When you're ready, enable screenshare on the stage screen.

Your show link is permanent — you can run it for a one-off set or keep the same venue for recurring shows.

05
🎤

Perform

Start screensharing your DAW, your camera, your visual set. The stage screen lights up. Fans see it in the 3D space. You're performing inside the room — not broadcasting at a camera.

The screenshare audio feeds into the spatial audio system. Fans closer to the stage hear it louder. It responds exactly like sound in a physical venue.

06
👥

Read the room. React to the crowd.

Watch your fans move through the space. Fans can use global voice to cheer. You can use interactive triggers — click events on stage objects, fan leaderboards, VIP zones.

The room is alive. It's not a comment feed. It's a crowd.
