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. Version 2.03 Date 1995.1.2 Restrictions: NONE Requirements: WB1.3 (V34) or higher, 1.5M RAM, two floppies or harddrive. Recommended: WB2.0 (V37) or higher, 3M or more RAM, 3M diskspace.
