TEDER

AGENT
HUMAN
SOUND

A game-audio engine for agents and humans.

DEVELOPMENT SYSTEM / 01

VALIDATED SOURCE.
ONE SHARED AUDIO MODEL.

TEDER is a TypeScript monorepo built around one validated audio model. The editor, offline renderer and browser runtime execute the same Tone.js graph, while MCP exposes a constrained set of project operations to AI agents.

THE PLATFORM / 01

Teder is a local-first engine for creating game sound and soundtracks with AI agents through MCP. Agents can create, edit and render audio assets as structured source; for people, that same work becomes a visual studio of virtual synths and sequencers for shaping, saving and reusing every sound.

KEY FEATURES

01MCP tools for AI agents

02Virtual synths and sequencers

03Editable, reusable sound assets

04Generative audio models — planned

THE FLOWCODE → SOUND → GAME

01GENERATE
AI agents use MCP tools to create and edit validated .teder sound, pattern and composition files.
02SHAPE
Open the same files in the editor to adjust synth, envelope, automation and sequence parameters.
03SHIP
Render WAV assets or use live browser playback. Direct generation with audio models is planned, but not yet available.

EDITOR ASSETS / 03

CODE. SHAPE.
SEQUENCE.

RENDERED DELIVERY / 01

AUTHOR ONCE.
TRIGGER IN PLAY.

TEDER supports rendered and live playback. For rendered delivery, the editor validates .teder source and exports WAV files; live mode runs the same cue definitions through the browser runtime.

RENDERED DELIVERY / EXAMPLEgame-audio.ts

// Rendered asset delivery example
const sfx = {
  jump: new Audio("/audio/player.jump.wav"),
  impact: new Audio("/audio/player.impact.wav")
};

function playOneShot(sample: HTMLAudioElement, volume = 1) {
  const voice = sample.cloneNode(true) as HTMLAudioElement;
  voice.volume = volume;
  void voice.play();
}

export function playerJump(player: Player) {
  player.velocity.y = -620;
  playOneShot(sfx.jump, 0.72);
}

export function playerImpact(player: Player, speed: number) {
  if (speed < 240) return;
  player.health -= Math.round(speed / 80);
  playOneShot(sfx.impact, Math.min(speed / 900, 1));
}
