The Explore Data Tapering Windows option is available from the Fourier Spectrum with Data Window, Fourier Spectra with Data Window Comparison, Fourier Spectra of Segmented Data, and Fourier Spectrum of Unevenly Sampled Data options in the Spectral menu.

Data tapering windows are used to reduce the spectral leakage in Fourier spectra. Since it can be difficult to commit the properties of the various windows to memory, especially when they contain an adjustable parameter, and since they are important in using a windowed FFT effectively, AutoSignal offers this Explore Data Tapering Windows option.
