Thank you ! - asio4all did the trick. I never thought it leads to such strange problems.

Hi, i get a strange sweep, if i am using a Soundblaster Z (optical out) and a UMIK-2 or 1 if i am raising the samplerate > 44kHz: The sweep plays too fast:at a time where it should reach approx 16kHz it is already fully played and it repeats then very fast a full sweep in the time for the last...

ahh - never mind... look at the graph you added in the post... The error came due to my 'fast' testing of the new equippment.

Hi John, thank you - adding the delay and putting some basotect panels around and in front below of the mic did the trick with jumping and the huge phase-span. This problem is solved! About the inversion: i thought that wont be a problem for measurements of only one chassis ? But how can you...

... and the calibration measurement

Here are my two measurements with the same setup. I already tried to deactivate USB sleep modus, but i get sometimes the jump in the phase anyways. edit#1: and i tried java soundcard driver, too - no change

Hi John, for measuring my speakers with time alignment i ordered a ECM8000 and i am using it on my Steinberg UR22MKII. I made the following setup: 1. no loopbak in Steinberg`s ASIO driver with 48kHz, i switched phantom voltag ON 2. i plugged MIC into INPUT 1 and my amp in OUT 1 3. i made a...

Ok - didn`t thought about that. But if i am using the acoustic timing reference i dont`t get the 'time-of-flight' from different speaker chassis. This is calibrated out of the signal. In my case i wanted to adjust the delay times for each of my three chassis to compensate in in my nanoshark...

Hi John, in my setup i use an ordinary Realtek onboard Soundcard with line out and line in and a calibrated miniDSP UMIC-1 for acoustic measurement. But with this setup i am not able to select my realtek soundcard input als loopback, because you offer this selection only for the chosen input...

Hi John, thank you! Is there any chance to test a nightly build (as you just released a new beta and the next seems to come in July) ?? Anyways, i will try the older ASIO driver you are using, too - if i can find it... SPo

And here comes an uncalibrated impedance measurement with warning (done several times with same results, open ends with 100 ohm resistor):

Loopback:

Switching the inputs doenst make any difference for impedance calibration - always (MINUS) -14:

Is there a possibility to adjust this delay in software ? Because it is constant it would be easy to set it once and its done? Maybe its because i`ve got several soundcards installed ? A Soundblaster, a miniDSP nanoshark USB driver, and a Realtek Driver... ? ...bunch of questions... :innocent...
