Automatically monitor and lock the volume level of the selected microphone on Windows.
When you are in calls or video conferences, your microphone volume can change unexpectedly due to application behavior or Windows settings.
In shared office spaces, high microphone volume can increase background noise and cause echo when several people in the same room join the same meeting.
MicVolumeLock is an AutoHotkey script that periodically checks selected microphone devices and restores their volume to a configured target value whenever it changes.
You can select the microphone and adjust the target volume level in the tray menu settings option.
