FFT

Employs the Fast Fourier Transform algorithm to compute the modulus of the Fourier Transform of each frame of input data.

Note, if necessary inputs frames are zero padded so that their width is an integer power of 2. The width of the output frame will be half the width of the padded input frame.

Inputs	Meaning	Sample	1-D frame	2-D frame

Outputs	Meaning
out1	1-D frame data after |FFT|

Parameters	Type	Default	Meaning
