  • Command Line interface for control of Spectrogram by other multimedia programs.
  • Full screen real-time scrolling spectrogram display or spectrum analyzer scope display.  Restrictions on display window size are eliminated.
  • Improved scrolling speed, even in full screen operation.
  • Selectable high and low band  limits for full screen display.
  • New peak hold, and left/right signal difference display options for the scope display.
  • More efficient memory utilization allowing display of larger spectrograms and higher frequency resolutions without memory shortages.

Please read the updated Help File for complete information on all of the new features.  Send comments, questions, or trouble reports regarding this new version of Spectrogram by clicking the "Email to Author" button below.

In order to support the continued development of program improvements, Spectrogram 6.3 is being distributed as shareware at a cost of $25.  The free demonstration program which may be downloaded below is fully functional, but has an operating time limit of 10 minutes each time it is used.  Registration of the program will remove this restriction.

The demonstration program may be downloaded either as a zip file for manual program installation by the user, or as a self-extracting setup program which automatically installs the program  and all necessary icons.  Either method results in installation of the same demonstration program.
