The interface is minimalist: a system tray icon, a master slider (0-500%), and a per-app list. A real-time VU meter shows incoming and outgoing audio levels, helping users avoid the red zone of distortion.

This version remembers your amplification settings per application across reboots. If you consistently need VLC Media Player at 200% and Chrome at 150%, the tool restores those levels automatically.
