Is there a way to know if any program is listening to my microphone. Windows 10

Is a simple way know if any program is using the mic?

Hover your cursor over the microphone in your system tray.

How to See What’s Using Your Microphone Right Now

If an application is using your microphone, you’ll see a microphone icon in your notification area, also known as your system tray. It’s black if you’re using Windows 10’s light theme and white if you’re using Windows 10’s dark theme.

Hover your cursor over the icon and Windows will tell you which app is currently using your microphone. If more than one application is currently using your microphone, Windows will show you how many applications are using your microphone.

...

If you don’t see the microphone icon, be sure to check the overflow menu by clicking the up arrow to the left of your notification icons. If the microphone icon is hidden here and you’d prefer it visible on your taskbar, you can drag and drop it to the notification area on your taskbar.

...

This icon only appears while an application is currently using, or listening to, your microphone. If you don’t see it, no applications are using your microphone right now.
