FFT Properties Download
Download FFT Properties v6 - Spectrum analyzer
The trial version of FFT Properties is available with limited functionality. The trial version becomes a full version with a correct registration key and by downloading a separate build. Because FFT Properties version 6 is a newer design, it does not yet fully replace the features in version 3. Version 6 is certified to work on Windows Vista, Windows 7, Windows 8 and Windows 10 and their 64bit variants. For Windows XP, you can try version 5.
