Never heard about such a strange hearing problem but you could measure the speakers normaly and add the delay later in eq-APO to the virtual speaker.
I tried normal measurement and added delayNever heard about such a strange hearing problem but you could measure the speakers normaly and add the delay later in eq-APO to the virtual speaker.
You need to explain things a little more(what you're trying to achieve?). I can't imagine that applying the same delay on speakers and headphones would give a similar experience. On speakers, the one with an added delay will still reach both ears. So the brain will still get the same interaural delay it's getting with any other sound source. It's just that one speaker comes in "late".I encountered a problem
The position of the sound is not accurate
Because my ears are inconsistent left and right, I have to adjust the delay to listen to the speakers or headphones to enjoy the stereo.
But after using impulcifer, it will cause the low frequency to shift to the left, mid to high frequency shift to the right, and even if the delay on the left and right is adjusted, the stereo sound cannot be normal.
The stereo sound that my ears hear is on the left (you can imagine that there is only left mono)You need to explain things a little more(what you're trying to achieve?).

While on headphones, it would clearly delay all sounds of one ear. those are 2 pretty different situations with different consequences for something like Impulcifier.
We must know precisely what you need, to even be able to consider if that can be properly done here.
Do you mean a delay of one channel of the already binauralised signal? That you should never do as it would totally destroy the binauralisation.Adding a delay after impulcifer
I hope you can use pictures to illustrate your correct usageDo you mean a delay of one channel of the already binauralised signal? That you should never do as it would totally destroy the binauralisation.
If you want to emulate the situation in which one real speaker is delayed then you should delay that channel in the input signal to the binauralisation process [Edit: with the binauralisation process I mean HeSuVi or whatever you use for that]: then one of the virtual speakers will play a delayed signal.

Google Translate is not very accurate.
That is easy in EQ-APO2. Unfortunately I don't know how to do it. Sorry.
if this 50Hz rockets are a bleeding of sort from the electrical grid, I would guess that the SPL values showed in REW are not the right ones and that at least one of your measurements needs to be done at higher SPL.So I played again with Impulcifier. I made even room calibration, but still the sound is bad.
I totally lost bass, the sound is like from the cheapest headphones :/ Also it's VERY quiet. Even after adding 20dB preamp it's still much quieter the without hesuvi.
Here is frequenccy response in REW before and after apply of Hesuvi
The sound is so bad that I wasn't even able to fix it by EQ. Whole soundstage is weird.If you want to lift the bass you can add a manal EQ to boost bass frequencies.
@Benik3 Can you show a screenshot of the frequency response shown in the analyse panel of EQ-APO? Did you use the Harman target for room correction? I use room correction with the Harman target and I have more bass then my headphones would provide without any pre processing.
Is it possible to upload your measurement somewhere?
I'm wondering if this would be generally a good idea to upload some measurements to get a feeling how different measurements are (more in terms of noise balance problems and different measurement equickment) and maybe to find problems that occur during measurements?
The 50Hz peak is really weird, but I don't hear anything like this and when I measure my stereo, it's not there:if this 50Hz rockets are a bleeding of sort from the electrical grid, I would guess that the SPL values showed in REW are not the right ones and that at least one of your measurements needs to be done at higher SPL.
No idea if you have other issues.
