Does anyone by chance have a copy? I have found a thread with a google hosted file that is long gone, just fancy a play...

oddly i have that for a polarity testing app on a usb already, i will have a play and see if it has the desired effect

the one i am speaking off was in a thread from 2017

Yea , I believe that might have been the same thread I read. Had to search internet high and low and found the pop test. Worked well for me with two way front stage, way better than frying my brain with pink noise trying to hear a doppler effect. It’s cool you can hear the pop move across the windshield, hope it works out for you

you shouldnt need to be adjusting timing by ear more than a few clicks if you use a tape measure properly. Also, the click track isnt very accurate by ear. Try mono pink noise if you really have to adjust timing. More so than not, EQ/levels are to blame for center being off. Not timing. Timing is very easy to get right.

Yup!

The only tool you need for timing is a measuring tape. As long as you measure carefully it will be the most accurate method as well.

Well, not exactly, but very close. It gets deeper than just using a tape measure, but then were talking about taking phase and impulse response measurements which are much harder to do/decipher and will only have a slight improvement through the crossovers

it gets much deeper, much more work with all the measurements, but results are better than just tape measure

fwiw, in my experience (rookie status) with the 80prs first time going active, I wasn't successful with the tape measure, pink noise doppler, Tracerite and definitely not my ears. I had more success with the speaker pop test and 16 band test tones for eq. Jumping in over my head with three way active was a learning experience. Reading about phase, impulse response, buying a umik-1 and setting T/A with Holimpulse proved to me that yes indeed the tape measure gets you close. However with the sub not so much, I group delayed the font stage to have wiggle room to get the sub in phase with the midbass. Then had to cut the right mid 3db to center the stage with the 31 band eq tracks. I guess what I am getting at is what has already been stated, is there's more to tuning than just a tape measure.

As noted, there is a big difference between TA and EQ. Both are required, and to some extent (depending on the frequency) both will help center the stage. Using a measuring tape will get you very, very close to done, you may need to make small adjustments, but changing it by more than a few clicks means that most likely the issue is one of levels, so you'll need L/R EQ to fix it.

TA is all about arrival times, sound travels at a pretty predictable speed, so simple distance measurements will get you super close to done. It's really not a complicated thing.

It’s more the sub I’m trying to get right, I’m also trying to find my way through holmimpulse and also contemplating a behringer mic so I can use loopback as it doesn’t work so well with a usb and a timing chirp... well I haven’t worked it out yet if indeed it can be done

To my simple brain I should be able to open up crossovers and get a delay figure from a chirp displayed in a timed environment, driver vs driver I’d think, surely if the mic is at the head position and both play a sweep or whatever for a ms and you purposefully spaced the drivers 20ms apart, then read the time between the two... so if it turns out to be 21.6ms then the delay would need to be 1.6ms if you follow my logic
