Given enough motivation (and I didn't have much to do the phase curve for PA5 ), I'd do this with DeltaWave. You can even use your two-channel method and compute delta phase between the two channels. But even without it, DW can remove any delays between two recordings.It is measured by a 2-channel method, both amplitude and phase error of the soundcard are compensated by comparing a measured channel with a reference channel. This is more difficult to make properly in REW, which asks for impulse response delay compensation and time shift, otherwise REW gives improper results in phase response.
