Hello John and all...
Been quite a while since I used your excellent software, as well as done any acoustical measuring. But, time to get back into things.
Something I'm seeing, is after I do the soundcard cal, I do a measure with the same loopback that I used, and I see the phase tilting up at the end of the range to about +30deg.
I get a nicely corrected frequency response, but I would think I should see the phase corrected to nearly 0deg, like I see at the low frequency end, shouldn't I? I believe I have a loopback connection, have got L and R on input and output connected, unless I have a cable problem. I see equal signal on both input channels, and I have Adjust clock with Loopback checked. Have I missed something else?
