What kind of window/zero padding is used?

[Adrian_S.]

I wrote a program to calculate STFT for the duaration of an analysis to examine the change in magnitude of the signals. Everything worked and I got quantitative results from it. I don't know exactly the math that was used? Is the default window a hanning window on this function? Is there any zero padding?

Edit: I used the Amplitude and Phase Spectrum VI

The Amplitude and Phase VI uses a Hanning window with no zero padding.  Under the hood, it is using the LabVIEW Extract Single/Multiple Tone Information VI, depending upon the exact input parameters.
