volume_control_for_voicemeeter

A simple and tiny tray application that syncs the in-Windows volume of the VoiceMeeter Input (VAIO) audio output device to the volume of the first virtual input strip in 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.

Features

• Instead of constantly polling the volume slider for changes, this app uses the built-in Windows' IAudioEndpointVolumeCallback interface, thanks to which, the program is completely idle and not using any CPU resources when the volume isn't being changed.
• Tracks the volume changes of specifically the VoiceMeeter Input audio device instead of the typical approach of tracking whatever the default windows audio device is, meaning that VoiceMeeter's input volume will be properly synced even when it isn't set as default (useful when outputting audio from different applications to different devices)
• Tiny footprint (0% CPU, .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.
