first of all, I've been demoing the headphone plugin with my K712 and K701 and I like the functionalities and how the GUI is designed. The general improvement sounds good to me, excerpt for some freq ranges. Maybe in that ranges my headphone model differ more from your average curves. I believe, that this may be improved with a personal calibration curve or with an optional parametic EQ option to edit the filtercurve.
Now to my point: I mix a lot with SPL's Phonitor technique, because with some kind of a crossfeed, I can create mixes which translate much better to loudspeakers. So, I was wondering what is the best way to combine your filtercurves with some crossfeed functionalities. What is your opinion about the following three points?
- inserting the filtercurves at the very end in the signalpath, behind the crossfeed? (not possible with e.g. Phonitor)
- maybe there is no problem at all, when applying the (L R - symmetrical) filtercurves before the crossfeed? (have you already tried/ measured that?)
- implementing an own crossfeed funtionality in your plugin? ;)
