Microphone Input

Question

Is there a way to get a microphone input event in c#? I would like to display a progress bar that goes up and down with the voice level.

What you're looking for is example source code for a VU meter. You can get the audio capture buffer with the Win32 API, but I've found it is far easier to use the BASS library. There is a .NET wrapper for it that is used by many projects out in the wild.

BASS: http://www.un4seen.com/

BASS.NET: http://www.un4seen.com/download.php?z/4/Bass24.Net.zip

In the examples zip file, you find some code for a VU meter. Their DLL does all of the work for you.
