WinPCD v1.610 Released 20 Oct 2022

WinPCD v1.610 is now available. A number of additions/changes have been made. 

The two major additions are two new tab sections.
  • Duelund Filter Targets
  • Vertical Polar Response Graphs
There are far too many changes to list here, but the major ones are shown below. For a complete listing of the changes go to ... ption.html.

Edit: Fixed the link above.

These are the major changes:
  • Front hemisphere power has a new calculation with a hemispheric weighting scheme that provides a more accurate result.
  • The power response graph now includes a listening window response calculated from front hemisphere data that is the power for a window that is +/- 10 degrees vertical, +/-30 degrees horizontal.
  • Complete re-do of uncorrelated power response. Uncorrelated Power is calculated using only on-axis data.
  • Many changes to reference angle treatment for Bessel calculation correction.
  • Frequency range upper limit is now 50000 Hz.
A new section with basic instructions has been added to the web site. These are for new and current users. New users should find them helpful for getting started, both in how to use WinPCD and the basics of setting up a project (session). Current users will find info on some improvements to current functions such as initializing textbook values. I had planned to do some training videos for this release, but decided that the instructions at the web site would be a better start. I may add videos at some point. It's not comprehensive and certainly not verbose, but with the screen captures will, I hope, serve as a good reference. ... index.html

My hope is that the improvements/bug fixes (many, many of those) will make it easier to use.

I've had this ready for quite some time, but did not want to release it without some sort of guide due to the extent of the changes. Many other things in life took precedence.

WinPCD v1.611 is now available. No code changes to 1.610. This has an install fix. If you have 1.610 working now, ignore this one.


WinPCD v1.612 - Inductor Listing Form

I've added a new form window that the user can call up from the System page. It displays a set of csv file data with inductor info by manufacturer/vendor. It shows the inductor value/DCR (mH/ohms). This should make it easier to finalize a design with actual inductors, especially for the DCR values that a key part of a design.

More details at my web site.


WinPCD Web Site Update

My web site has some updates to provide a more useful layout with a few changes. The index page has been made into two with release history separate. The index is more a short description, taken from the program About page. At the bottom will be any topics of discussion that I think will be informative. There is one to start on Hemispherical Integrated Power Response. This has some general discussion on the topic with details of the calculations in WinPCD.

I've also added a link to the Instructions page for Polar Help. It details the System tab polar setup and use.
