File-New-Project/EarTrumpet ? reverse-engineered prompt

Build me a Windows app like EarTrumpet that makes audio control way easier than the default volume mixer.

I want a small tray app that lets me see and change the volume for each open app, quickly mute things, and move apps between different playback devices. It should also let me pick the default output device, support hotkeys, and feel native on Windows with light mode, dark mode, and accent colors. If possible, make the interface clean and modern, with a simple mixer view that’s easy to use from the system tray.

Please make it work smoothly on Windows, and include support for multiple languages if that fits naturally. Look up current docs online if you need to, and build it so it feels polished enough to be a real daily driver app.
