AudioPanUI — Alpha Version
AudioPanUI is a lightweight Windows utility that automatically pans application audio left or right based on the position of the active window on your screen.
Move a window to the left → audio shifts left. Move it right → audio shifts right. Center the window → audio recenters smoothly.
The goal is subtle, natural spatial awareness across single or multiple monitors without manual mixing.
Version: v0.2.0 Alpha
Stability: Core engine stable, GPU-safe rendering enabled
Scope: Early public preview for feedback
This build is intended for real-world testing, not final release. As to being stable, this version has not had any noticeable bugs while running 3 days straight.
- Note: 'Headphones' & 'Speakers' on the Output selection are for preferable presets - not actually changing audio sources
- Real-time stereo panning driven by active window position
- Smooth, equal-power panning, with motion smoothing
- Independent handling of multiple windows playing audio
- System tray mode
- Single global hotkey:
- Ctrl + Alt + P → Toggle panning
- Turning OFF automatically recenters audio
- GPU-safe software rendering for maximum stability on external monitors
- Single-file executable (no install required, but larger file size)
To keep behavior clean and predictable:
- No dead-zone snapping
- No complex configuration UI
- No custom hotkey editor
These may arrive in later versions based on feedback.
- Launch AudioPanUI.exe (fully extracted from ZIP file)
- The app can minimize to the system tray
- Use Ctrl + Alt + P anytime to toggle panning on/off
No installation or administrator rights required.
- Early alpha UI polish is minimal
- Some background/system audio sessions may appear in logs
- Multi-monitor edge behavior may evolve with feedback
No hardware risk — the app only adjusts software audio balance.

This alpha is shared free for testing. No guarantees, no warranty — just an experimental utility being explored.
