Spatial Audio Volume
Two apps. One head. Move closer to one — it gets louder. The other quiets down.

A short walkthrough of the app driving real Windows audio sessions.
What it does
- Lists every audio session on your default render endpoint — same list as Settings → Sound → Volume Mixer.
- Two slots, left and right. A draggable "you" avatar between them sets both volumes from a single position.
- Sessions identify by PID, so two windows of the same app don't move together.
- Drives WASAPI directly. No virtual devices, no rerouting.
