Frequency Analyzer in C#

问题

I'm looking for a C# source code that performs a frequency analysis on a WAV file and displays the results in a graph, similar to the one displayed in apps like WavePad. Do you know where I can find such a code?

Thanks!

It's in a very experimental state at the moment, but if you have a look at the WPFDemo project in NAudio, it performs an FFT on the incoming microphone data or sound file you play and plots it under the wave-form.
