If you start the demo “Audiolense XO” mode, you can use “Setup/Edit Speaker Configuration/Cross Over Configuration” to change the number of speakers as well as change the XO frequencies. You can also change the width of the XO on the “Speakers” tab of this popup form.
When you select “New Measurement”, it uses your XO selections to generate individual driver frequency ranges. You can change the default frequency ranges of the sweep for each driver if desired in the “New Measurement” form.
Hope this answered your XO question.

Welcome to the forum!
This timing variation is a concern of mine. It is likely to have a negative influence on the time domain correction, even if the correct delay values are entered manually. The timing of each frequency is likely wrong, and thus, the time domain correction will make things worse … even where it was right in the beginning. If the drift is small, the time domain correction may be effective into the kHz region, which could be enough, but this is really a concern that I want to eliminate. The Dacpro8 is a perfect partner for Audiolense so I am making a serious effort to make the measurement work with it in the loop.
Yes, the demo only works for full range correction. But there is a 3 month satisfaction guarantee on the license purchase. Plenty of time to evaluate and ask for a full refund if things doesn’t turn out the way you want.
Mvh,
Bernt

Hello everyone, My name is Cornelis and I am new to this forum. Today I have been working on the demo version. A versatile and interesting program. Like some dacpro8 owners here on the forum, I was unable to get reliable delay measurements. With both Asio4All and mme, the delays differed per measurement, despite the "Excellent Dynamic Range" compliment. ;) Luckily I had measured the delay earlier, with the help of Arta and VituixCAD. Now I wonder if you can just change the measured values without affecting the measurement and the resulting correction. Maybe measurements with an incorrect delay are always unusable. This question also applies to changing the crossover frequency. The standard 3.5 kHz is really too high for my 6.5 inch midrange. It is a pity that it is not possible to listen to the result with the demo.
Hopefully someone can advise me.

Audiolense handles two clocks.
If the streaming is reliable you will in any case get the same differences from measurement to measurement … as long as you use the same sweep duration. If you’re getting different delay values with the same settings, there’s a streaming problem somewhere.
Mvh,
Bernt
