The full licensing terms for each program can be found in the file “LICENSE.RTF” included in the distribution files below.

ScopeDSP Suite is a combined license to the Professional Editions of ScopeFIR, ScopeIIR, and ScopeDSP for just $999 – a savings of $398 compared to purchasing them separately.

Please Note: The files below were released on August 22, 2016 so they are very new. As the well meaning but not-so-bright watchdogs that they are, Windows’ SmartScreen Filter and commercial virus scanners may bark scary warnings about these perfectly nice houseguests until they get to know them. However, all Version 6 distribution files and the executable files they contain are signed by Iowegian International Corporation, so you can be assured that they are published by us. (“Bad dog! Now quit barking and go lay down.”)

Installation Note: For best results, we highly recommend you install ScopeFIR, ScopeIIR, and ScopeDSP on a local drive rather than a network or mapped drive. The reason is that their help systems are in Microsoft’s “HTML Help” format, and Microsoft’s operating systems won’t open help files in Microsoft’s preferred help format if they aren’t located on a local drive. (Go figure…)
