Inherit FFT length from input dimensions

When selected, uses the input frame size as the number of data points, N

fft

on which to perform the FFT. Tunable.

FFT length

The number of data points, N

fft

, on which to perform the FFT. If N

fft

exceeds the input frame size, the frame is zero-padded as needed. This

parameter is enabled when

Inherit FFT length from input dimensions is

not selected.
