WinPCD v1.516 - Session file save/restore bug fix

Version 1.514 had a serious bug that was fixed in 1.515. Right after that was released I  received a report that the filter settings weren't saved correctly. A fix has been made and is available to download (v1.516). This goes back to when I created WinFilters. Session files for PCD &am...

WinPCD v1.514 - Export to file from graph right-click context & WinGraph v1.002 change

Two programs have minor changes.  WinPCD: All graphs have a right-click context menu for various operations, most built into the graph software used. I added export commands for SPL and impedance complex data. However, I recently found that I exported the wrong element for filters, SPL and impedance...

Version release v1.513 (UI responsiveness), 5 Jan 2018

Prior to this release the user interface locked up when the polar calculations were being made. No windows could be opened or moved, even the polar window would accept no user input. There was a single thread. With this release the user can now open, move or close windows to include the polar plot w...

Re: WinPCD v1.5 / video questions

I've had an update to the videos in mind. Now that I've finished these last changes, I'll consider doing them soon. There's no reason for missing schematics. I just ran my installed version. The window opens using the Schematic Overlays button on the System tab. The crossover elements won't show unt...

Re: Version release v1.510 - Polar response improvements, UI changes and small bug fixes

v1.510 changes: Has a bug fix for 3-ways with a midrange having higher order highpass that truncated the summed response if the midrange low end went down to 0db. The polar response section is improved to more accurately reflect the off-axis response. Please read the Help provided carefully. It's im...

Re: 2.5 Way support?

Hi Rob, I may look into this at last, but it's a big addition. I had new work until recently and limited time. The latter will still be somewhat limited as I will now need to do additional study on software towards another contract. Still, I may see what the effort required is, but it won't be any t...

Re: Impossible to download ?

Sorry to be so late replying. There have been a few instances of this and I don't know the reason. It's some odd thing related to the Click-Once installation. Installing a later version has at times worked (1.501 is now available). What you can also try and should work, if you already have a good ve...

Other changes to the UI cover several requests made in the forum here and elsewhere. The window size can ...

Re: Another ZMA Question

You should use the impedance in the box. The box alters the impedance as seen by the crossover around Fcb (closed box) of the box. This may affect the interaction with the crossover if the crossover Fc is close enough to the box tuning. WinPCD has no box model capability, at least not yet. I'd like ...

Re: Problem with importing ZMA's?

WinPCD does drop anything below 10Hz. For purposes of a crossover, <10Hz doesn't have any impact in passive systems. This is subwoofer territory, so I left it out since it would simply add additional processing time for no benefit.
