Using latest REW (v5.19) and rePhase (v1.4.3). REW measurement look normal and I saved them in all possible formats: .frd, .mdat, and .txt that looks like
* Freq(Hz) SPL(dB) Phase(degrees)nd
24.902 84.084 -105.945
25.082 84.107 -105.906
25.264 84.148 -105.738
etc.

Now going to rePhase and trying:
1. In main menu "Import measurement" - none of the above formats recognized
2. From "Measurement tab": "import from file" -> it takes both .frd and .txt files but then produce same result: just solid vertical line as magnitude and dotted phase curves.

Attached picture shows REW measuremen on top and rePhase import result underneath.

What am I doing wrong?

Hello dima1stg

REW exports measurement with an absolute SPL magnitude, so the passband typically ends up in the 80-90dB range.
On the other hand rephase expects measurement with a magnitude somewhat centered around 0dB.
You need to adjust the gain offset in rephase to something like -85dB (give or take) in the measurement tab in order to see the magnitude trace appear.
