Hey.
I want to access the line in volume in C# .net 4.0.

I dont need exact decibels but I want to be able to gage what the volume is relative to a previous point in time.

Preferably I want to be able to poll the sound volume every 100 ms and build an average of the relative sound loudness.

My end goal is to be able to set a threshold when the sound in the room is to loud and i can get a warning.

I know its possible, MSN Messenger does this in it's setup.

There's nothing "built-in" to C# to do that sort of task.  You either need to do extensive P/Invoke interop work with native Windows APIs, or look for a ready-made wrapper for .Net.  I also know Windows XP and Windows Vista/7 have very different ways of handling audio.

Have a look at NAudio - it's a .Net wrapper around the Win32 APIs - it's the only such library I know off the top of my head, but I've never used it.  I'm sure there are others as well.
