Method Description
FFT ( ) : System

Construct an FFT with default parameter values
Transform ( IEnumerable signal ) : IArray

Transforms the signal based on the current settings. Returns the first half of the result, which is a reflection of the second half.
TransformRaw ( IArrayView input, FFTOutputType outputType = FFTOutputType.Power, WindowType windowType = WindowType.Rectangular ) : IArrayView

A static transformation method. The length is the nearest power of two that is not greater than the input length. Returns the full result.
