My idea here would be not only to have this working for myself but also create a process, a guide and tools so that pretty much anybody can do it themselves. In that sense it's not realistic to ask the random headphone enthusiast to know or to learn how to detect distortion in the impulse responses or even to go read through manufacturer documents. What I really would like to have is a almost one click solution which processes the sine sweeps, analyzes them, gives warnings to user if things didn't go as expected and of course produces the output impulse responses which can be directly used with different convolution softwares. Something like what I did with my AutoEQ project. Of course the user still needs to own the mics at minimum so it's not quite possible to have that low level of commitment from the user.
