To coordinate the time of subs and mains, you need to set a delay for the main ones. Not for the sub.

I have Windows 10-64. Most likely, your problem is related to Linux.

I have such a keyboard. I can check if your keyboard shortcut works for me. For example, the smoothing toggle works for me on the latest version.

John Mulcahy, The blue graph has a shaky look. See post #33. What is the cause for this phenomenon?

I was able to get data from the microphone for the Java driver. For the Java driver, L was assigned as the output channel, although the connection was in R. For the ASIO driver, R was assigned as the output channel. So this is my carelessness. John, I'm sorry for the trouble. I could not imagine...

Now everything is working as it should. Thank you.

To answer, you have to take 4 measurements. Left main, right main, near sub, far sub. All 4 with acoustic synchronization by, for example, the left main.

I'm not looking at the numbers you're looking at. I look at the source, at the graphs. Between the first peaks there are 386 microseconds, between the second peaks the time cannot be determined, because the second peak of 20k did not work out. The first and second peaks may not reflect the...

The difference is not 1.2 ms, but 0.14 ms. The measurements of 200 and 500 are almost the same. The 20k measurement differs by 0.14ms. The Umik-1 microphone does not have its own clock oscillator. It takes the clock rate from the USB bus. Therefore, each new measurement is slightly different...

It looks like you"re doing everything right. I have my doubts that the self characteristic of this microphone is flat. Did you calibrate it in the sound lab? Or did you compare the measurements with it and the calibrated microphone?

Yes. I have not encountered such a thing.

Is it a tweeter graph?

I would try to replace it for a while.

If you want to keep it that way, measure each sub separately. Far sub as is, near with MSO delay, using acoustic synchronization over the same speaker with the tweeter. Then do the addition of the measurements in REW. You will get the measurement of the combined sub. Second option. Turn on both...

You should first adjust the delay of the near subwoofer relative to the farthest one. Then you can make their sum using REW mathematics, then determine the delay of the main one relative to the sum of the subs. Comparing the impulses in the overlays tab can help you. This will bring you closer...
