Is there any way I can check and use .sofa files. Because otherwise I have spent hours Upon hours and have a .sofa file I cannot use.

You find the files in my edited post in the Mesh2hrtf thread. It was just a stupid error yersterday from my side.

Isn’t that something to go with grounding?

Let's say that it is the typical sounf of problem of electrical ground : but could be anything, the computer, the zoom H5... but i suspect the mics

the mic have a jack connection, you can easily try them with another device

But one thing that worries me is that "humm", a typical sound of ground loop : if the mic touch something, my finger, the earplug, i hear this humm - I monitor it directly to the zoom H5 . Then if i touch the vxlr, the hummm disappear. One mic do this, the other less. Anybody has experimented this ? The humm is not so huge, but i can differentiate it from noise and so if i increase the level of the H5 input do decrease volume, this humm will be more important. My mics are primo EM258. I ve tested pluggin the mics to a little mixing table, same thing.

I encountered the problem too. Solved it by buying new audio jacks and soldering the mics again. not sure what's the exact reason...

@musicreo i'm stuck with the headphone measurements: if i aim for the headroom, with 3db headroom i get some weird sinusoid, irregular

this is my latest headphone measurement compared to my old measurement with 10db headroom

should i still aim for headroom or should i stick with the best sinusoid i get?

@ reter & @ conql
I think this problem sometimes occurs when you use a stereo jack with a mono device; i don't say this is the problem here, but could be. Perhaps i will try soldering mono jack or not soldering one of the stereo plug on the jack

I was getting something similar and what @Xam198 said I was using slightly different stereo device with a mono cable

 

[Xam198]

That's definitively a ground problem : when i unplug the zoom H5, the "hummm" decrease. And if i touche the vxlr with my hand, no more humm. I will try to change the jack

i don't really understand if you were answering me or him, what did you do to fix? also what's your headroom?

I was saying his suggestion that using a mono cable with stereo or stereo cable with mono device could be right because I was getting the same jittery peaks and I used a mono cable with a stereo device.

i checked, i plugged all the devices on the behringer so i think that is some distorsion created by the volume being too high? but lowering the volume raises the headroom and rising the mics does nothing... so i'm in a loop, should i keep my headroom high to mantain a good sinusoid but still trying to get the lowest headroom possible?

@reter Don't worry about the headroom

 

[reter]

@reter Don't worry about the headroom

so i should stick for the better sinusoid i can get, right?, ok thanks @jaakkopasanen

@jaakkopasanen can we extract the headphone compensation info from impulcifer like the text files we use in hesuvi?

I’m in between impulcifer and mesh2hrtf both have their advantages (impulcifer gives me the spacial sound like the speaker are around me 6ft away. And mesh2hrtf gives me crystal clear sound like I’ve done the measurement in an Anechoic chamber. I want to try and merge the two so I’m getting a perfect hrir.

now that you tried both, what do you prefer and how much spacility does mesh2hrtf have compared? i prefer the spaciality and i think impulcifer gives already a clear sound, the disadvantage of course is that it's limited to the room you're doing the measurements so if you're in a room you will have reverb more or less... i think the best way to get the best with impulcifer is measuring outsite, without walls and without noise
