WhiteHole - Zero-Latency Audio Loopback

Modern macOS + tripos audio loopback driver for inter-application audio routing with minimal latency.

Repository

• Source: https://github.com/bmorphism/WhiteHole
• Language: C (CoreAudio driver)
• Platform: macOS (AudioServerPlugin)

Core Concept

WhiteHole creates virtual audio devices that pass audio between applications with "hex color #000000 latency" - effectively zero perceptible delay.

┌─────────────┐     WhiteHole     ┌─────────────┐

Installation

# Clone and build
git clone https://github.com/bmorphism/WhiteHole
cd WhiteHole
xcodebuild -project WhiteHole.xcodeproj

# Install driver
sudo cp -R build/Release/WhiteHole.driver /Library/Audio/Plug-Ins/HAL/
sudo launchctl kickstart -kp system/com.apple.audio.coreaudiod

Integration with Gay.jl Colors

WhiteHole devices can be color-coded using Gay.jl deterministic colors:

using Gay

# Assign deterministic color to audio channel
channel_seed = hash("WhiteHole:Channel1")
channel_color = gay_color(channel_seed)  # e.g., LCH(72, 45, 280)

Use Cases

1. Multi-app audio routing - Route DAW output to streaming software
2. Audio analysis - Tap system audio for visualization
3. Virtual soundcards - Create multiple virtual devices
4. music-topos integration - Route SuperCollider to analysis tools

Tripos Integration

The "tripos" in the description refers to the three-way (GF(3)) audio routing:

Channel	GF(3) Trit	Purpose
Left	MINUS	Primary signal
Right	PLUS	Secondary signal
Center	ERGODIC	Mixed/balanced
