C# and soundcard

Want to build a simple piece of equipment to do electrical measurements and display the results. As an analog => digital input device I want to use the soundcard.
The main problem is: How to get the information out of the soundcard.
I also want to use C# (if possible).

You might have to contact the Vendor of the soundcard to get information on what data/objects they expose. Also when you have this information you could then just use some com bindings to the unmanaged classes that the soundcard drivers expose.

Now remember that all this is in relation to the type of information that you would like to pull out.

The first question you should ask yourself is if it's possible to get your information into the sound card. Sound cards filter out low frequencies so you can't measure DC voltages.
