VoiceWalker transmits your voice only to pilots that are actually close to you. Full volume in the immediate vicinity, smooth falloff at distance, silence far away. The effect is a natural „airfield chatter“ feel: taxi neighbours are loud and clear, traffic across the field fades away.
All defaults can be live-tuned from the built-in debug panel (Ctrl+Shift+D).

Head-Related Transfer Function rendering turns stereo headphones into directional audio: you hear from which direction another pilot is speaking. Inverse-distance falloff and cardioid mouth-direction dampening make the experience feel physically plausible – the pilot behind you sounds different from the pilot next to you.

The world is split into geohash cells (~20×20 km). Pilots inside the same cell find each other automatically via public WebTorrent trackers – no central server, no login, no account. Pilots in Frankfurt and Tokyo live in completely separate meshes, so bandwidth stays tiny and private.

Optional push-to-talk with any HOTAS, yoke, rudder pedals or button box. Plug it in, click „Assign key“, press the button – done. Works even when MSFS is in the foreground.
