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:

{
  "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 }
    ]
  }
}
