Inaudible

Visualisation of raytraced sound in 3D games for deaf people.

Inaudible is a Unity-based prototype that explores how sound propagation in 3D environments can be represented visually. Instead of relying on audio cues, the system raytraces sound through a scene and renders visual feedback to convey direction, distance, and intensity of sound events.

The goal is to improve accessibility and spatial awareness for deaf and hard-of-hearing players, while also serving as a research and experimentation platform for sound visualization in games.

What this project is

This is not an audio engine or a drop-in Unity package. It is a research-oriented proof of concept that demonstrates:

• Raytraced simulation of sound propagation
• Visualization of sound paths and interactions with the environment
• Integration of sound visuals into a real-time 3D scene

Repository structure

• Assets/ – Unity assets including scripts, shaders, and scenes
• ProjectSettings/ – Unity project configuration
• Inaudible.slnx – Visual Studio solution file
• .gitignore – Standard Unity ignore rules

Features

• Sound raytracing
  Emits rays from sound sources to simulate how sound travels through space.

• Visual feedback
  Uses shaders and debug visuals to represent sound direction, reach, and intensity.

• Unity integration
  Designed to be embedded directly into Unity scenes for experimentation and prototyping.

Requirements

• Unity 2019 LTS or newer (matching the project’s original Unity version is recommended)
• Visual Studio or another C#-compatible editor

Setup and usage
