Send a sine sweep through the simulator and see what kind of harmonic distortion you're getting (harmonic distortion shows up as lower-level sweeps above the original sweep). You can deconvolve the sweep and get the relative levels of each harmonic at each frequency, but that takes a bit of work.

Will give it a try once I have the time/gear. Thanks!

It wouldn't be a crossfeeding process then.

​Apparently, to get this to work in HQPlayer you need two files for each driver (two for left and two for right) so a total of four files and then they get combined through the matrix pipeline.

If you say so... https://www.dropbox.com/s/c2yess5tgnz8hx0/30deg%2024thoct-single%20channels.zip?dl=0

Here's to hoping you get it working

Thank you very much for posting these.
 
This worked beautifully in HQPlayer! I'm using a PCM resampling down to 44.1 kHz and with your impulse response files used the following matrix pipeline settings:
 
Source channel / db / Mix channel / Filename (including full path)
1 / -6 / 1 / Left-L.wav
1 / -6 / 2 / Left-R.wav
2 / -6 / 1 / Right-L.wav
2 / -6 / 2 / Right-R.wav
 
It sounds even better than using Foobar with your stereo wav files.
 
Can you also make the 50 degree files available? 
 
Next I'm going to try and see if there's a way to use these with higher resolution music.  Apparently I may be able to work it if I use HF expansion in the HQPlayer convolution options.  Alternatively, any chance these impulse responses can be captured at higher resolution?
 
This is really good stuff Joe.
 
EDIT: I went ahead and tried it with some higher resolution source music and I didn't have to do any convolution HF expansion.  Unlike Foobar, this HQPlayer handled the differences between the source music and the impulse response without any issues.  I'll have to spend more time listening to see if there's any other artifacts introduced but first impressions are positive.

Question? Is there a way to "record" the dsd processed cross feed to a file that. Outdoor be played back on a portable device? It would be great to have these kind of files on the go.

Yes. Foobar is especially equipped for this. Just choose dsp effect in conversion dialogue.

I've been doing some cursory research on how speakers create their deep soundstages, and I'm really struggling to find anything useful at my very very very very low knowledge level. I'm wondering how exactly something like this works, and if it is at all possible to build hardware that imitates the sound of speakers, maybe with a hardware implemented crossfeed that also utilizes reflected sounds or something.

My earphone listening experiences have been ruined by my new speakers and I've been trying to breathe life back into my earphones.

Have you managed to load the plugin and files described here?

ah, I meant useful as in to learn the basics of sound. The plugins work and sound fantastic, I find it quite amazing.

That is what Stax did with their Sigma series. They look strange but do improve soundstage with a more upfront presentation than conventional headphones. The idea is that the electrostatic driver do not point straight into your ears, they lay in front of your ears the way speakers do. They reflect sound also from the sides into your ear as well.

The way speakers give you dimension is as follows:

The speakers should be about 8' apart
When music plays, 1 channel is out of phase with the other.
When the speaker plays on one channel it will reach one ear slightly before it hits the other. For example your left ear hears the left ear first, then your right ear. Part of the indication for distance in a recording is based on one ear hearing it first(of course if it is straight forward both ears hear it at the same time, indicating it is front of you) hearing it first, and the slight delay before being sensed by the other ear, as the wave also picks up contours of your face as it passes to the other ear. These contours of your face and the shape of your outer ear helps determine the direction of the sound source. The out of phase that speakers do is to blend each channel to each other, so it can give a sense of space. This helps give you left to right separation, and the mix from each channel will help separate how far apart each sound is left to right. The front to back separation is determined by the volume of each separate instrument. So a mid left instrument that they want to be a little behind the group will have the instruments volume a little lower in each channel, with more of the instrument mixed to the left and less to the right. This combo would make it sound like the instrument is on your mid left to center, a little further back than other instruments.
Hope this clear description for you.

Speaker channels should NOT be out of phase with each other.

Hello, great job. In foobar2000, the scene actually appears as if it were true stereo. And I ask how to implement this in the DAW system, for example, to load your IRs in the VST plugin? I haven't found a corresponding right-left split plugin with binaural processing at the moment. Thanks

Use e.g. mcfx convolver, you'd need to read up a bit on writing a .conf file for it

Yes you are correct in the phase
