- Update to GFFT Version 1.12.
-
- GFFT is an FFT-based spectrum analysis program with many features. By
- operating from stored sample data files, it offers higher resolution and/or
- accuracy than real-time analyzers. It accepts 8, 12, or 16-bit data in in
- IFF 8SVX, AIFF, and AVR formats, or in unformatted files, and can accept
- data points entered through a console in floating point.\n
-
- GFFT can be operated from either a Workbench GUI or from a CLI in
- interactive or batch modes. It has built-in help facilities for all
- operating modes with a 170+ Kb help file.\n
-
- GFFT can produce high quality spectrum plots on screen, plotter, or
- printer, or save to Postscript or TeX files, or output spectral data in
- text form to a console or file. (GNUPLOT, a separate program by other
- authors, is required for plotting features. GFFT is designed to invoke and
- control GNUPLOT automatically.) It can plot in 2D (Amplitude vs
- Frequency), or 3D (Amplitude vs Frequency vs Time). It allows the
- selection of logarithmic X and/or Y axes, the dB scaling of X, and
- arbitrary 3D rotation. GFFT can show multiple spectra in the same plot, or
- append spectral data bands from earlier sessions.\n
-
- GFFT provides 8 selectable FFT window types, including Blackman-Harris 92
- dB. It can apply a special weighting for pink noise testing. Smoothing,
- calibration, ranging, and quantization are also available. There are no
- arbitrary limits to the number of frequency bins or smoothing points, or to
- the length of data which can be analyzed.
