Hi Joelha,
This is not supported in Audiolense due to measurement quality consideration. It is very difficult to verify that REW measuremens are OK, and they are often not OK. And then the sound quality will suffer. And it is even more concerning when a 3rd party measurement is used because the measurement fails in Audiolense. The problems that become so visible in Audiolense tend to manifest in the form of odd-looking and inconsistent measured impulses.
Usually a number of measurements has to be taken and often there is such a high degree of varations between them that it is impossible to establish whether a measurement is 100%. I have worked with Mitch Barnett on such cases in the past, and quite often we have been unable to establish that a measurement has a correctly timed impulse response.. Through a triangulating approach ... several measurements of different durations and using different settings, comparing actual distances to speakers with the measured difference, listening tests etc ... it is often possible to establish that one or more of the measurement, although not perfect, probably are most likely good enough to provide decent basis for correction. But then again there's a risk that none of the measuremens are good enough.
You can ask Mitch if is willng to help you, as a paid service. He has the tools and the skills, but this is a time consuming services and a successful outcome is not guaranteed.
With good hardware and everything up and running, the measuremens will be 100% identical timing wise from measurement to measurement. And then you know that the measurement is 100%. and then you know that the simulations etc can be trusted. Reliable hardware is the only 100% solution to this problem.
