mathnet.numerics DLL

[trags3]

Hi all,
I have a need to incorporate a Fast Fourier Transform into a LiveCode App. The process as I understand it would be to use LCB to access an FFT DLL.
mathnet.numerics.dll is something I know can do what I need to do. I know I would need some code to do things like defining the source of the sound (a microphone), start and stop the FFT and export the beginning and duration of musical notes played into the microphone.
My experience with LCB is NONE, but I think the task at hand can be accomplished with LCB.
The other problem I have is although I have used Fortran, Basic, dBase, and Livecode I have no experience with any version of C. You Tube has an example using C# and mathnet.numerics DLL that does most of what I need except the LCB part of course.
Here is a link to the referenced YouTube video:

Can someone help steer me in the right direction?

Thanks,
Tom
