# Spatial9 Inc.


## Generative Spatial Audio™

Spatial9 is an artificial intelligence company pioneering **Generative Spatial Audio™**, a new paradigm where AI systems understand Audio and automatically generate immersive spatial sound environments.

Our mission is to enable creators, developers, and platforms to transform traditional audio into **interactive and immersive spatial experiences** using AI.

Demo at **[https://spatial9.ai/demo](https://spatial9.ai/demo)**

# What is Generative Spatial Audio

Generative Spatial Audio is the capability for AI systems to:

* Understand musical structure and sonic roles
* Detect instruments and acoustic layers
* Place sounds in three-dimensional environments
* Generate spatial movement and interaction
* Adapt mixes to immersive playback formats automatically

Instead of manually mixing spatial audio objects, **AI becomes the spatial mixer**.

This allows creators to convert stereo music, video audio, and stems into **immersive spatial scenes in seconds**.

# Core Technologies

## GravityLLM

GravityLLM is the world's first **Spatial Audio Language Model (SLM)**.

GravityLLM understands musical structure, instruments, and acoustic constraints to automatically generate spatial audio scenes.

### Capabilities

* AI-driven spatial object placement
* Music-aware positioning and motion
* Automatic immersive mixing
* Scene generation for immersive audio formats

GravityLLM converts:

```
music + constraints → spatial audio scene
```

Example output:

```json
{
  "scene": {
    "layout": "7.1.4",
    "objects": [
      { "class": "lead_vocal", "az": 0, "el": 10, "distance": 1.5 },
      { "class": "pad", "az": -70, "el": 20, "distance": 4 },
      { "class": "fx", "az": 110, "el": 30, "distance": 6 }
    ]
  }
}
```
