That takes a while longer than real-time application with integrated convolver.
Thanks. Whats already present is pretty useful then. Export the impulse response and listen to the XO through something like Jrivers convolver and a multichannel DAC.
But an embedded convolver in vituixCAD allowing real time emulation would be really great.
I agree with your view that there is no substitute for good measurements and simulation. But being able to actually hear the effect of various factors involved and presented in simulations will take this to a whole new level.

Could you add a module for half-sine wave measurements like in this document? In my opinion it is a good method of dynamic measurements.

One possible problem with this is that .wav exports are normalized to get full bit-resolution without clipping.

.bin and .txt exports are more suitable for emulation with external convolver because they maintain original gain for each way. miniDSP binary file is "normal" 32-bit IEEE (float) mono.

I think VituixCAD will stay as a simulator. Measurement program would be different project. Personal motivation for that is also quite low because I already have CLIO FW1+MIC1+10+11, ARTA, justMLS, SoundEasy (very old) and several freewares; HOLMImpulse, REW, ... None is perfect but I can live with those.

Thanks very much Kimmo ! VituixCAD been a very help tool to me for past few month.
I been using to to V1.1.3.1. But today, when I try to update to V1.1.7.0, the installation process was blocked by AVG, due to "Unknown Software" reason, so, my question will be
Is it possible for me to download previous version ? Like V1.1.6.2 or V1,1,6.3?

I second VituixCAD stay as simulation tool, I also use HOLMImpulse & REW, it is good to me - for now.

This kind of warnings are common because I'm not registered publisher. Older version does not make any difference. For example this is from my PC (Win10 Anniversary with Defender):

Windows protected your PC
Windows Defender SmartScreen prevented an unrecognised app from starting. Running this app might put your PC at risk.
More info
Don't run


Just select More info and Run anyway.

Contour lines with graphics methods is doable. It's slow as tired snail because color of every pixel on chart area is read few times. dB step is constant. 5 dB looks okay.

Optional Contour lines for Polar map added in revision 1.1.7.1. Steps are initially 3 dB, but can be adjusted via user.config. See changelog. Code is optimized to get acceptable speed (faster than tired snail).

Yet another for the "keep it a modeler" group.

..at hobbyist-pricing there is also:

Complete package all software module




I've got Soundeasy and it's improving it's in-software modeler.. BUT..


I'd pay (about $150) for an add-on to VituixCAD that had a 3D view and diffraction "shell" model IMPORT (like Enclosuer Shop mentions - pg. 8) from FUSION 360 (..which is free-use to hobbyist's - like your program), and a physical driver off-set for the crossover.

https://www.autodesk.com/products/fusion-360/overview

(..and maybe adding a group of simplistic driver models (diameter and diaphragm/dustcap depth) to the Fusion 360 database for people to "place" in their "shell").
