I experienced inconsistencies with the delay to the acoustic timing reference in the past and that's the reason I make 3 measurements and discard those out of range. Mic is UMIK-1.
However I was in a hurry here for a quick test regarding polarity.
Now I'm interested in determining what is causing this issue. The UMIK-1 itself? The system configuration?
On Debian 12 , where it seems to be way most frequent, I have this message all the time REW is running. It's non stop:
Here we have 3 measurements for a 3-way speaker enclosure (with 3 power amps; electronic crossover). We should have the same difference between T0 and REF, The first one is the speaker with all the 3 power amps running; the second has it's midrange power amp turned off; and the last has its Low and High power amps turned off, leaving only the midrange active. I could understand if the midrange measurement were off range as there is no tweeter for the acoustic timing reference and the upper limit for the midrange is 4500 Hz.
350-400 msec are expected.
