The idea way would be to just make an HRTF profile using this technology and 3 pictures of the individual and then calibrating the the specific headphone the same way the realiser does it.
Well, this is interesting. Too bad there are no current products that use that approach to creating personalized HRTFs.
Since this is modeling just the HRTF, not a theater sound system, this could theoretically be used to present a true 3D binaural sound image, not just 7.1, when fed with the proper positional data.
Come to think of it, does anyone actually sell earbud microphones for the headphone calibration part? I haven't seen any that weren't packaged with the Realiser.
