Spectrum Analyzer for line-in?

Question

I'm looking for a small control (and the code behind that analizes) that shows me the incoming sound of my line-in/microphone.

I'm using winforms with c# and the control might if possible fit my toolbar.

Answer 1

Have a look at the WPF demo project that comes with NAudio that shows a very basic spectrum analyser implementation. You would need to rework the graphics for WinForms though.
