Monitor soundcard output in Windows 7 with .NET

Is there a library that I can use to monitor any sound output from my computer? I'd like to trigger certain actions when different audio levels are reached. I think it wou开发者_如何学Gold have the same components as building a VU, I would just be doing other things rather than visually displaying the levels. I don't want to play music, only monitor any sounds that my computer is making (I am assuming this is monitored through the soundcard, though I could be mistaken).

Is there a library for this? I'm having a hell of a time finding anything. I might just not know the right terms to search for.

I'm only specifying .NET because I assume it's the easiest to access low-level windows stuff. If there's a way to do it with another language, I'm open to that possibility as well.

Thanks,

Mark

The IAudioMeterInformation interface in Vista and up. This is only easy to use in C++ code, there's no type library for the audio interfaces. Maybe you can google somebody that already wrapped this.
