3.67 FAQ-304 Does the FFT computation truncate or pad my data?

Last Update: 2/3/2015

The FFT tools are based on the FFTW library from MIT. The routines in this library do not require the signal size to be a power of 2 and therefore no padding or truncation of the signal is done prior to the computation.

Keywords:padding, truncation, power, two
