A simple and tiny tray application that syncs thein-Windows volume of theVoiceMeeter Input (VAIO) audio output device to the volume of the first virtual input stripin Voicemeeter (which corresponds to that same device).

This allows the built-in Windows volume slider 🎚️, any mixer apps' (e.g. sndvol.exe, EarTrumpet, etc) sliders 🎚️ as well as gestures and keyboard volume keys ⌨️ to control the volume of Voicemeeter.

Written in Rust 🦀

• Instead of constantly polling the volume slider for changes, this app uses the built-in Windows'IAudioEndpointVolumeCallback interface, thanks to which, the program iscompletely idle and not usingany CPU resources when the volume isn't being changed.
• Tracks the volume changes of specifically theVoiceMeeter Input audio device instead of the typical approach of tracking whatever the default windows audio device is, meaning thatVoiceMeeter's input volume will be properly synced even when itisn't set as default (useful when outputting audio from different applications to different devices)
• Tiny footprint (0% CPU,0.5mb RAM).
• The application properly unregisters with Voicemeeter's API when exiting, which prevents leaking resources and causing visual weirdness in the Voicemeeter's GUI.
• Tray icon visually consistant with that of Voicemeeter.
