In my search for interesting software, I found a very interesting and useful package called Visual Analyzer. It is written by an Italian gentleman named Alfredo Accattatis (http://www.sillanumsoft.org/intoduction.htm).
The software can be downloaded from http://www.sillanumsoft.org/download.htm.
The software is "donate ware," which means that it is free for you to use but you get additional support if you make a donation via PayPal. It is well worth a generous donation in my opinion. The following screenshot is of the main window.
One annoying thing that I discovered about the site is that the pages are not linked together very well, so I am including useful links wherever I can.
Main screen of the Visual Analyzer
The main window displays two functions simultaneously. The top half is the oscilloscope view and the bottom half is the audio spectrum analyzer view.
Oscilloscope window
The oscilloscope window contains all the controls that you would expect to find on a bench oscilloscope...
