Leyline

Leyline is an audio platform project focused on desktop voice processing, virtual audio routing, and real-time DSP experiments on Windows.

This repository is the portfolio hub.

Components

Component	Repository	Purpose
LeylineFilter	slategraydev/LeylineFilter	Larger desktop audio filtering project and original exploration path.
LeylineFilterMini	slategraydev/LeylineFilterMini	Minimal Tauri, React, TypeScript, and Rust desktop app for a fixed voice-processing chain.
LeylineVirtualAudioDevice	slategraydev/LeylineVirtualAudioDevice	C++ virtual audio device work for Windows audio routing experiments.
LeylineVirtualAudioDeviceRust	slategraydev/LeylineVirtualAudioDeviceRust	Rust virtual audio device work for Windows audio routing experiments.

What It Does

Leyline is built around a practical audio workflow:

Microphone or input device
  ↓
Voice cleanup and gain staging
  ↓
Virtual or physical output device
  ↓
Apps like Discord, OBS, games, or recording tools

The goal is to make a clean, developer-owned audio stack for routing and processing voice audio on Windows.

Technical Highlights

• Rust backend work for audio-state management and DSP experiments.
• Tauri, React, and TypeScript desktop UI for fast iteration.
• Windows virtual audio device research in Rust and C++.
• Fixed-chain processing model to avoid plugin-grid complexity.
• Focus on real-time safety, latency visibility, and practical routing.
