We could also say that it is possible to design very good speakers without measured phase or without off-axis measurements or maybe without measurements at all. Corrupting measured phase by default is one step towards blindness and ignorance. Last edited by dlr ;PM. WinPCD - Windows. Comment Post Cancel.
Here is one example. All far field measurements of higher frequencies are processed with minimum phase calculation for the right side simulation. Then far field is merged to near field measurements of lower frequencies which are processed with diffraction simulation to convert quasi far field. Difference between acoustic centers of coax tweeter and coax cone is defined with excess group delay method.
That is simple and fast if separate sum measurement is not available or shape is too bad for three measurement method. Difference result was mm which is entered as negative value to Z coordinate of coax cone and woofer. Z of coax tweeter is zero. Both methods are valid for that part.
Minimum phase method gives the same magnitude and phase responses as with actual measured phase so difference detection with excess group delay method was okay. But problems start to rise step by step to off-axis, and 40 deg is already ruined at higher XO freq.
This error will even increase to rear sector with closed boxes because sign of distance differences swap. Bad result with minimum phase method is fully expected.
I suppose experienced designer is able to ignore power response and directivity index simulation with this kind of driver geometry to avoid wrong choices in crossover design. But it would be unfortunate though not my bad if someone willingly throw useful information away due to limited measurement gear or method.
It would be really nice if we could produce a video documenting that process, because it is quite complex. There are a lot of things you have to pay attention to but I'm getting the hang of it. Right now I am developing an Arduino based turntable which will hopefully interface with ARTA to automate measurements.Login or Sign Up. VituixCAD problems getting started. Posts Latest Activity.

Filtered by:. Previous template Next. I've been out of speaker building for about 20 years and decided to jump back into the sickness. Previously, I had never used any computer sim software, so on that end, I am a total newb. I've unzipped them and placed them into a folder for easier access. When I click on them, I see the file name lade into the box below.
But nothing else happens. They do not fill in any of the graphs on the right half of the screen. I've watched 3 or 4 tutorials on Youtube about the software. In all of them, when they click on the file, it populates the graphs. What am I missing. I did a search on the forum, but did not see anything relevant to my problem. Thanks in advance for any tips. Tags: None. You need to click on the driver symbol in the crossover window and assign the driver data to it at the bottom.

I put mm for X and Y and it made no difference. Still no plots. I figured it out. You have to connect a line from the "amp" to the "driver. Got it going now. Chris Roemer. I think there's a "sticky" at the top of this forum by "undefinition" - a.
Paul Carmody that leads you through what could be considered a "generic" prep procedure. Yes - use the diffraction tool to generate frd files which take into account baffle diffraction. This will also simulate the directivity of that speaker on that baffle, and generate a series of frd files at 10 degree increments.
This allows you to design simulate off axis response and see the whole shebang. You guys are getting a little ahead of where I am at this point. I've been out of the game for quite a while.Kfm obituaries
I've only been reading back up on it for a week or so. LOTS to learn and relearn. I've got some drivers from back in the day that I was going to build some 2.

Just happened to notice that VituixCAD v2 has been released alongside version one, which is still being developed. Also, you can set it to display a polar diagram now, instead of the directivity sonogram view or the 3d waterfall graph. I don't know why we don't see this software mentioned here more - it's free, and the user interface is fantastic, and includes a great diffraction modelling tool with dipole functionality full box modelling, an SPL tracing tool, etc.
Tags: None. Awesome piece of software. Even when it wasn't free, it was quite formidable. The greater learning curve might have something to do with why it isn't cited more often. Just my thoughts Comment Post Cancel. Originally posted by olu78 View Post.

May in DIY. I just installed this DIY software, and it looks damn impressive. Perhaps it has a steep learning curve though. Also, I can't confirm its accuracy yet without testing.
All that said, it looks stunning from the webpage. I discovered it by pure chance when doing a google search recently.Redmi note 5 test point
I'm looking forward to messing with it though. I'm limited by the technology of my time, but one day you'll figure this out. Tagged: diy Software Untested. May Nice find. I see the author also has a Linux via Wine installation guide.
I might take some time this weekend and try that out on my old laptop running Linux Mint. If I can measure and model in Linux, then I will be very close to making the migration across the board to Linux. I took the program for a spin using my "Dual Exhaust" project data. My modelled Z offset in XSim is 1. I get a very good match to my XSim on-axis model. So I plan to load my XSim off-axis data and test this next.

Diffraction simulator is executed with Baffle step button. Adjustable box parameters: Volume [l], Qa, Ql. Fb [Hz] is calculated. Diffraction simulator calculates cabinet impact response of driver s in a baffle.
Simulation is based on simple ray theory: each driver is a point source sending 72 rays towards baffle edges with fixed 5 deg steps. Path lengths of shortest 1 st order diffractions are calculated and summed with delay i.

One possibility is to add two small default buttons to help setup. Sequence would be: 1: open all tweeter's far field, click FF1 button, set left window, adjust right window, export 2: open all mid's far field, adjust right window, export 3: open all woofer's far field, adjust right window, export 4: open all near field, click NF button, export done maybe too easy.
For example 15" PA coaxial might need mm left window due to depth of tweeter's acoustic center. Buttons will be in the next revision. Everything else is done with VituixCAD.
Minimum phase checkbox is for microphone calibration file only. That application is now VituixCAD. All rights reserved. Yes No. OK Cancel.
