Easy to use C# audio library for spectrum analyzer?
The FftSharp link led me to exactly the right place!
The creator of it also has a project called CSharp Data Visualisation which has an example of a FFT graph from any audio input or output (i.e. Desktop Audio).
I'll modify it to send the values to my neon bargraphs through serial port and that should be it

I will then send those amplitude values to my arduino through the serial port so it can display it on the array of neon bargraph tubes I made. The arduino handles the actual displaying and protection for the neons and circuit. That is already all covered. Here it is displaying a sine wave.
What I'm struggling with is getting the values from the desktop audio source.
