Just some feedback.

I love these with my Q701 and my iems, but not really with my AD700x. I know it's subjective and I can't quite pinpoint why I don't like it without using very vague terms so I won't try to explain the experience. Maybe you can test your crossfeed plugin on the AD700x if you ever get the chance?

Cheers!

Edit: was a problem on my side. It's fixed now!

Give TB Isone (I subjective find it better) a chance, it's very good with my M50x.
 
Anyway, Joe, I recommend your crossfeed plugin to anyone that likes headphones. It's fantastic!

Okee, it actually works(wouldn't have figured it out myself in a million years tho, this script puts a knot in my brain).

 

Spoiler: Warning: Spoiler!

Preamp: -4.7 dB
Copy: L2=L R2=R
 
#Left
Channel: L L2
Convolution: IRC_1003_C_R0195_T030_P000.wav
 
#Right
Channel: R R2
Convolution: IRC_1003_C_R0195_T330_P000.wav

Copy: L=1.0*L+1.0*R
Copy: R=1.0*L2+1.0*R2

 
would be best to copy the .wav files into ".../EqualizerAPO/config", and make sure that the sampling rate of the audio device is set to 44.1Khz.
 
This would be with Joe's files:

Just out of curiosity, if I was to switch the left and right stereo channels, would I need to change anything, or can I just leave everything as is and simply add this?

Sorry if this is a stupid question. I just started using Equalizer APO and am trying to figure everything out.

yes that should work, but it should be put at the top, before all the channel mixing stuff for the convolver happens, or in a separat file.
 
(it's only useful if the channels are swapped in the first place, with wrong soldering or something, otherwise it would destroy the stereo image)

Thanks!

I wear my IEMs flipped.

It gives me a better seal so... Yeah.

The only way to give headphone listening is to employ some form of crossfeed. How one goes about doing it is left to personal preference. I have already stated my preference and am sticking by it.

Wonderful plugin. 10/10.

Ye, i must say it throws the sound way out of your head, even more than those virtual surround processing which comes with soundcards.
 
On the other hand it affects SQ quite a bit.
 
It adds another HRTF(from Joe) to the headphones, which are tuned to have some kind of their own HRTF equalization(diffuse field) anyways.
The question is, what should be the target curve for the headphones, to subtract their own HRTF and have only one HRTF(from Joe) active?
 
And what would be left over, if you could also subtract the room and the speakers...
 
As of now, you trade the "out of your head", with the benefits headphones have over speaker when it comes to SQ.

Actually, I designed these HRTFs with the assumption that the headphones are doing a fine job of HRTF equalization... yes, but only equalization.
With that in mind, I processed the initial measured HRTFs until their overall effect on the tonal balance throughout the spectrum is... zero.

What the HRTFs do then, is only add the temporal effects of a pair of speakers playing in a real room, and the *relative* tonal effects between the speaker sounds arriving at the near ear and the far ear... none of which can possibly be simulated by the headphones themselves.

And what would be left over, if you could also subtract the room and the speakers...

This question shows a misunderstanding of head-related transfer functions as they relate to a realistic soundstage. I also thought ideal loudspeakers in an anechoic chamer were the ideal for HRTFs to simulate, until some wise words from smarter people in another forum led me to experiment in other directions... and the result is what we have here.

one fundamental problem is how people estimate the sound quality. in a typical situation where you have some DSP to use, the person will try with and without the DSP on his headphone, and if the sound changes too much(less bass, some change in the clarity of the mids, or some other feeling often found with crossfeed solutions), the listener will conclude that it audibly alters and reduces sound fidelity.  it's the logical conclusion in such a test where the default headphone sound is used as reference. but here is the problem. even on our preferred headphone, the FR is wrong, the stereo is wrong, the reverb is wrong. that's the starting point most of us use as if it was a valid reference. what could possibly go wrong? well everything ^_^.
 
when I listen to my speakers, I get a phantom image in the center that is located a good distance behind my screen(that's badass for movies). switching to the headphone like I do every night to avoid being a jerk to my neighbors, the singer usually lands somewhere in my nose or forehead, and many instruments come from full right or full left, this is stupidly wrong in so many ways that I don't understand why people still mention fidelity when they talk about headphones without DSPs. if I use my speakers as reference instead of my headphone, it becomes clear very fast that almost any crossfeed or surround plugin brings me closer to the experience I get with the speakers. it's never perfect, and a few really wreck my brain. it's not the kind of stuff that works perfectly for every heads.  but it's really rare when I think that the headphone without DSP or EQ was the better sound. I like to have the band in front of me, I like to have some reverb, and I like to EQ the headphone to my own preference. all those to me, improve the sound quality as I get me a tiny bit closer to speaker experience.

So what is the ideal way to measure  pure HRTFs? To my knowledge ideal loudspeakers in an anechoic chamber is the best way.

Which loudspeakers?

Small update: it was a problem on my side with the software setup of my computer. It's fixed now. Both sound great.

I wish I could find stuff made for others that feel great for me. but most of the time it just doesn't work for me the way it should. I came to the conclusion that I have a weird head. the logical conclusion when average HRTF won't give the expected result.
still I was curious about the foobar stereo convolver, and it appears to be the real thing(meaning true stereo, not just left impulse on left ear and right on right). so now I'm fooling around with some HRTF models straight in foobar and for free. pretty cool .
@Joe if you know of some convolver also with true stereo that I could put in VST host, that's would be sweet. I'm considering buying something, but free (or dirt cheap)always tastes better ^_^.

@ castleofargh If you are looking for a VST convolver than the free convolvervst would be my choice.

There is also a directshow filter included that can be used for example in some movie players like MPC-HC. It supports true stereo and even binaural 7.1 (16 channels) is no problem.
