Short: GFFT 2.03 spectrum analyzer
Author: cpp@crl.com (Charles P. Peterson)
Uploader: cpp@crl.com (Charles P. Peterson)
Version: 2.03
Type: mus/misc
Requires: 2M RAM; 2M disk space
Replaces: misc/sci/gfft-1.12.lha
Distribution: Anywhere and everywhere!
GFFT Version 2.03 is the update to GFFT version 1.12. The GUI is improved
considerably (allows any font and screen color setup, has progress
indicator, uses tooltypes, etc.), more features are added, bugs are fixed,
and a new SpectrumAnalysis.guide is included (with lots of pictures) to
explain spectrum analysis.
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.
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.
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.
