This is the template for the "Page-per-block Docs". This first section should describe what the block does and how to use it, using however many paragraphs is necessary.

Parameters

FFT Size
Number of samples used in each FFT calculation, which also determines how many points are in the output.
Forward/Reverse
Whether to do an FFT or IFFT.
Window
Type of window to apply to each set of samples before the FFT is taken, default is a blackmanharris window. The argument of the window.blackmanharris() function is simply how many points in the window, which must match the FFT size.
Shift
Whether or not to do an "fft shift" which puts DC (0 Hz) in the center. If you are not sure what this means, leave it set to Yes. Only active when input type is complex.
Num Threads
Number of threads to assign to perform the FFTs.

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI
