- Electron version: `0.37.0`
- Operating system: All

I've been trying for weeks now to figure this out, I need to somehow capture the audio output from my electron application.  But the `desktopCapturer` API appears to exclude that exact use case :cry: 

Is there an alternative way of performing this capture WITHOUT capturing the entire computers audio through the "screen" capturer?

Also open to any JS methods of capturing a stream from an Audio element
