Audio Switch

Changing microphones or playback devices during a game or stream often means reconfiguring every open app. Audio Switch keeps each app connected to a stable virtual endpoint and changes the physical route behind it.

• Designed and built the Rust workspace and native Windows app independently.
• Built the routing model around user-configured endpoint roles rather than hard-coded device names.
• Worked across real-time audio behavior, native tray controls, local control interfaces and hardware-button integration.

• A live WASAPI routing engine for primary and secondary playback plus a switchable physical microphone behind a stable virtual endpoint.
• Native Windows tray controls, configurable keyboard shortcuts, saved endpoint settings and route-status feedback.
• Playback mirroring, drift correction and synthesized audio cues around device changes.
• A local control protocol and Stream Deck bridge with a packageable native plugin.
• Optional Windows startup behavior and a separately controlled high-priority execution mode.

• Rust workspace targeting native Windows APIs and WASAPI rather than wrapping a browser or Electron runtime.
• A device-neutral routing model keeps games and communication applications attached to stable virtual endpoints.
• Real-time audio paths use bounded queues and drift management while control behavior stays outside the audio callback.
• Native tray, registry, keyboard, local protocol and Stream Deck surfaces share the same routing core.

• Built a focused native answer to a recurring multi-device audio problem.
• Expanded my personal work into Rust, Windows systems APIs and real-time audio engineering.
• Established the application, control protocol and packaging foundation while driver and distribution work continue.
