Some more pictures from the last tests with TDA:

Pic1. Mutual cancelling of the front channels (appr. 260, 460, 800, 1600Hz) and influence of the infrasonic filter.

Pic.2 - Best possible dfr for the present install (3way passive)

Pic.3 - 2D delay presentation



As one can see, cancellations on the first pic. are gone. Without infrasonic filter the sub became "closer" to the front. Sounds more tight and accurate.

Ok gentlemen, I need help in figuring out what I'm doing wrong. I went to the apl/tda website, and decided I'd try the tda trial software.....so I was informed I needed to download some software, don't remember the name......version 2013 8.1mat play or sumthin.... and I followed the link and did that....then I downloaded the trial version of tda. The only evidence I see of tda on my computer is the installer program....I've installed a number of times yet still no tda on my computer that I can find.....ugh. Can someone please walk me through exactly what they've done to make this work on their computer? I hope so, I've read the directions on the tda site, and I'm obviously missing something. Please someone help this barely computer literate feller out!

In order to use TDA you need to download and install Mathworks Matlab compiler runtime (MCR) 2013a 8.1 according to your operating system type, Windows 32 or 64bit!

Please check what version of windows you have on your PC - 32 or 64. I have never had issues during installation of this program on XP.

My goal with my new build is to produce a TDA plot that shows 0ms delay at all frequencies :P

Might sound impossible but I'd like to try, with properly implemented FIR processing, the low frequency group delay can be removed to a large degree...

Mine was doing the same thing, you need to extract the files from the zip, then just click on the little TDA icon like normal.

I had this message too but with APL workshop, it was the wrong matlab thing installed. But it seems you have the right one (8.**).
With TDA I have a popup every time I start, something about admin rights, but it works.

Horny Froggy...

Did you install it as admin too? Try 32bit version even if you use 64bit. Also did you install matlab before tda?

Yes, there is a specific option for opening it as admin. Right click on the TDA icon that opens the program and you will get a menu of options. You will see an option to open/run it as Admin.
I had to extract the files from zip and run it as admin. When I only extracted, the program would open but not let me measure.

Default Re: TDA (Time-domain analysis) - Measurement Software - Review

Ok I'll just do it step-by-step:
1. Find the zip file you downloaded. It will be "APL_TDA_v008_64b_demosetup".
2. Right click on it, select extract.
3. Select where you want the extracted files to go.(just make sure you remember where you are sending them so you can find them).
4. Find the files you just extracted.
5. One of the files you extracted will be "APL_TDA_v008d_64". The 64 is assuming you are running 64 bit as opposed to 32 bit.
6. Right click on that file.
7. Select "run as administrator"

Give that a shot.

Woohoo!!

Thanks to all who offered advice. We have success!



Now, is my mic cal file needed at all for the measurements I'll be taking? I'm thinking no, but figured I'd ask......

Plus any more tips for the measuring would be appreciated....

Btw this isn't my car in the pic.....just the lappy speakers as I tested to see if it would measure.....seems pretty straight forward.

Default Re: TDA (Time-domain analysis) - Measurement Software - Review

claydo, congrats!

Waiting results from your car. Try first one channel (f.ex. left front) + subwoofer.
3D pictures are more exciting to look at, but I prefer 2D as they give more precise information regarding group delays.

It is funny always to null all the TA settings and to check actual delay of both fronts from the listening position. Then - delay each speaker in order to obtain the simultanious arriving time. To connect the sub is typically the biggest problem. Sometime, phase switch is necessary along with selecting of the most optimal filter orders between the sub and mids.

Do not forget that it is possible to rotate 3D-images. This option could give you some additional info.

Default Re: TDA (Time-domain analysis) - Measurement Software - Review

One thing that surprised me was how accurate my "by ear" t/a was. Of course there is room for improvement, but I'm having trouble relating the p99's adjustments to what I'm seeing on the screen.

I still wanna try a complete 80PRS tune verses the Helix.. The Helix continues to win. Would love to play with the 99RS's more extensive EQ. So you playing with the trial version of this software?

This would be for all.. I am perplexed with TA and our beans.. What I mean is our "mic's" on our heads have two, not one, and they're several inches apart. This is the conundrum I'm dealing with concerning a measured TA tool verses ear alignment. Were it speakers very far away and more in-front, instead of car with wider speaker placement and short distances, I could fathom that a single mic point would be pretty darn spot on, but when drivers are so wide as they are in car and your ears are also relatively wide apart, how's it work?

Yup, playing with the trial version.....I have yet to improve much from my initial reading.....need to learn more about what I'm seeing I reckon.....

It seems to me when I go moving the blackness of the trace? (For lack of a better term) It will lose its symmetry and become squiggly....lol, technical terms......then it doesent always move in correlation with my adjustments.....it seems pioneer has some funkyness in its t/a adjusments, or I need to read up somewhere on what exactly the tda is seeing.....
