How to combine compensation filtercurves with crossfeed tools?

Hi all,

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? ;)

Best Regards

Julian

Hi Julian,

Thanks! Glad to hear the calibration result sounds good to you.

When using an averaged calibration profile it is fine to insert the plugin before the crossfeed is applied because the correction is same for both channels.

If, however, you were using an individual calibration profile (separate correction curve for each channel), you'd have to find a way to insert Reference after the crossfeed. It looks like this would not be possible when using Phonitor.

At the moment we don't plan to implement a crossfeed feature in our plugin but there are other software solutions for this out there!

Let me know if this helps.

+1 for a good controllable crossfeed with adjustments to match HRTF.

There are not many good plugins for headphones out there (I could count them with one hand). I think there's a real opportunity for your company to become a leader in that under-exploited but expanding field (because of pro studio work, home studios, audiophiles, more listening constraints of time and space, etc.).

+2 for crossfeed in the headphone plugin AND Soundigo.

Would be great!!!

I'm a big fan of Phonitor as well. What I ended up doing is reconstructing Phonitor's crossfeed filters using a custom software plugin, and then inserting it before the headphone normalization plugin. Works great.
