I agree that measurements with open ear canal where the mic is inserted into the opening of the ear canal are more difficult compared to measurements with mic placements in front of the the ear canal opening. But for me the open ear measurements gave me the best results after some post processing.
Yes enough this can vary from measurement to individual. My translator may have written down my writing somewhat misleadingly. Sorry
nd this is post. Now I see that decay is controlling somehow...And probably I'd like to increase low end decay, not sure how still
Okay I overlapped it on Photoshop to make it easy to see.
This is Your L (FL-L, FL-R)
And This is your R (FR-R,FR-L)
And if you overlap both sides (4 channels), you can definitely see a difference.
We can confirm that your current recording has not already been consistently measured left and right from the room file. (This is not only a simple imaging problem, but it can also feel quite complicated confusion.)
Now let's focus on your original story.
The first issue I have is around 3khz peak,
This means that the headphone files that are currently applied to the room files are not the same characteristics (that is, they are not properly equalized).
So this needs to calibrate the headphone file. 3k sounds high because 3k is less recorded on the headphones, and because the impulcifer overcompensates it, it sounds more excessive when actually audited.
Not only IEM, but headphones are not perfect even if you measure them with a microphone in your ear. To be the perfect headphones.wav file, you need to wear headphones and listen to the sweep without any change when you listen to the headphones.wav in reverse (hesuvi is off). But most of the time it doesn't. That's why you need an EQ.
In other words, some headphones reproduce well, while others say BRIR didn't work very well. The same goes for IEM.
However, if the correct base file is prepared, most BRIRs should sound almost the same no matter what device you use, except for distortion characteristics such as the device itself's thd.
Therefore, the solution is that we need to do additional eq.
And the second one is the reverb. While Impulcifer has reverb management to REDUCE RT60 or decay, whatever, I need something to INCREASE a bit the reverb tail to much my room and jbl305mk2 perfectly. Especially what I really miss is a thump reverb from kick drums and bass, it also reduce some width in the low end.
Yes, when I compared my blocked and closed echelon measurements, I saw these bass problems sometimes. Of course, I saw that even my blocked echelon measurements sometimes didn't have a perfect low pitch (especially for small 3mm microphones)
Sometimes it's not just a bath below 100 Hz, but from about 200 Hz, it's quite often not enough to be recorded differently from what I actually hear.
So to compensate for this, we also need EQ.
You can simply listen to it and EQ it, but you can also look at the sum response (LL+LR, RL+RR) in the REW and calculate it accurately to compensate for it. If you have a micromeasured room impulse like Umik-1, Earthworks, you can also compare it and correct it correctly.
And yes. Impulcifer has the ability to cut Decay (a kind of gating), but it doesn't have the ability to increase it.
The really simple thing is to bring your Hesuvi file to Audacity and increase the gain in the time band you want (for example, 40 to 150 ms), or just increase some frequency bands. Or you can add Late Reflection as VST. These are very simple solutions.
And if you want to manipulate the space more precisely, that's when the words change. You have to synthesize the file by looking at it in us units rather than ms.
And you need information from multiple directions, not just a simple reb, and you also need HRTF from multiple angles.
But I don't think you want this, and I think Bass itself might get the feeling you want with a little bit of a reverb because it's normal not to be able to recognize the direction without the port or room mode issue of the woofer unit (80hz downband).
And now you see a peak at about 150 Hz and a little dip underneath it. There's quite a lot of difference and this may sound like Bass is even more lacking.
