RACE based cancellation in ear measurements.

I forgot a few days ago when I was organizing the spectrum, just thinking about leaving a post.
In fact, it's an image that doesn't have much to do with XTC itself.
Let's look at the graph first.
Top is 40~110ms Spectrum
Bottom is 110ms~
If we look at it more easily with smoothing
(It's a bit inaccurate because it's a spectrum of reflection areas, and it's about hearing multiple angles at once, but hearing multiple angles at once doesn't reduce the ILD.
And the long-distance HRTF itself of more than 2m does not change much, so please pay attention to that part and watch it for fun.)
40-110 ms: You can see a significant decrease from the typical ILD
110ms to : ILD is almost non-existent (there is no difference between the two ears)
And when I convert this into distance, taking into account the distance I hear, the path of the reflection, and the size of the space, the minimum value comes out as follows.
Approximately 8.3m reduces the ILD a lot.
Approximately 20.2m is the same enough that the ILD no longer exists. (It depends on the amount and quality of the initial reflection, but once the ILD becomes almost the same, the sense of stereotacticity will be lost and will only be felt in cotton.)
And yes. We wouldn't have this kind of listening in a normal household lol
But I expect it to be an image that supports the part about Crosstalk and distance that I mentioned in other threads before.
If we go back to XTC, the closer the distance, the stronger the correction, the more unstable the correction will be, and the further the distance the ILD will naturally decrease and the required correction will decrease, and the more natural the correction will be.
