DSPLib - FFT / DFT Fourier Transform Library for .NET 4
Steve Hageman, 4 Jul 2017
DSPLib is an complete DSP Library that is an end to end solution for performing FFT's with .NET 4

What DSPLib does
DSPLib has several main parts, but it's basic goal is to allow a real Fourier Transform to be preformed on a time series input array, resulting in a usable classic spectrum output without any further tweaking required by the user.
Basic Fourier Transforms (FT) come in two basic types: The most general form can produce a spectrum output from any length of input data. This type of transform is called the Discrete Fourier Transform or DFT. The code is simple and brute force.
The Pros are: The input data can be any length.
The Cons are: Since it is a general method, it is computationally intensive and large input data sets can take a very long time to calculate.
A more specific type of FT is called the Fast Fourier Transform or FFT.
The Pros are: It is much, much faster to compute than the DFT.
The Cons are: The input data length is constrained to be power of twos. The code is more complex to understand.
