Recording Impulse Responses for Speaker Virtualization

[morgin]

You use dolby atmos for headphones as alternative to your measurement ?

I use Dolby atmos for headphone in the playback option in the lg tv which is used as the listening device for vb cable. Vb cable is still set to 7.1 and off in spatial sound tab. It’s kinda hard to explain without many screenshots.

So windows playback tab click my device (lg tv is my default sound device) set to Dolby atmos for headphones then set the bit depth to 24 48000 (have to do in that order because it changes) leave the speaker options alone which will change to stereo because of Dolby headphones.

Then on the playback tab click vb cable. Change the speakers to 7.1. Then bit depth 24 48000. And off in spatial sound. Make this the default device

Then recording tab and set my listening device to lg tv (my default sound device) and 24 depth 48000.

Not sure if the big change is because my tv can decode Dolby but it has made a massive difference.

Yes, it's not an impulcifier problem. a problem with my windows.(Or motherboard? CPU? I don't know)
It works well on other PCs that work.
I think a lot of people are talking about the perceptions.
I've heard all the surroundings work at the correct angle on other PCs with my files, and on this PC I'm using now, I feel like there's something wrong with deploying surround signals on Windows 10. It's not that I don't hear it like it's in front of me, but I can literally hear the movie star's saying behind my back.
You can't imagine, can you? This is all I can explain. I don't understand. Why this happens......... =(
What's even stranger is that I went to a friend of mine who runs a computer store and tested it on some of the newly created PCs, where the surround was properly angled, and there was a PC that sounded behind my back like I experienced on my PC.
I just don't get it. -(

Could the problem be there was too much sound reflected from the back wall when doing your measurement?

Try what I was forced to do and record with one speaker but instead of putting the speaker behind you. You use one speaker for all 7 measurement and turn your body instead.

From the way you explain it, it sounds like you use EQ-APO on Vb cable and send the output to your LG TV. On your LG device you enabled Dolby Atmos for headphones.
But i see no reason for enabling Dolby Atmos for headphones.

I get 7.1 without enabling Dolby atmos and just using the normal guide.

But I’ve found when I do use Dolby atmos for headphones it’s like I’m in the movie and not just sounds around me. Also listening to music is as I’m in a live recording.

Dolby atmos for home theatre gives me a similar effect but not as distinct. Windows sonic is less than Dolby theatre but still usable.

I was just experimenting and didn’t think setting Dolby on my listened device made a difference on my default playback device but it really does.

Unless the center is really mixed into the side or rear channels and creates a phantom center. To check this I suggest to try your hrir without HeSuVi. I attached your hrir with a different channel configuration and a txt file that you can include in EQ-APO configuration editor and that does the convolution. You just have to put the wav file and the txt file in the config folder of EQ-APO adjust the folder path in the txt file and deactivate the Hesuvi entry in the EQ-APO configuration editor.

The trick is, that I included a line that mutes all rear output channels. This way you would hear nothing if the center channel is mixed into the rear channels.

Thanks for making. When i listen, Front L,R,C,SUB is in my head. just like normal headphone. And Rear, Side is Mute.
Maybe somethin not work correctly. (Of course, I changed the convolution path of the text file to suit me.)
Because

Because I can't see anything and it's just full of clipping.
If i single-convolve the wave file you gave me

And it's probably not APO or Hesuvi's problem.
It could also be compatibility with the motherboard (audio chipset).

Because I tested a total of 4 new computers today, and there were PCs that worked regardless of Intel, Ryzen, and I also experienced the Center being heard behind my back the same way I'm currently experiencing on my PC.
So I'm going to give up my experience with 7.1 for the time being. I've already done everything I can on my PC... =)

No. It's not messurement problem. I have already tested and tested on several other PCs with my brir file. Exactly worked very well in each surround position and the Room I recorded has good reflection control.

How are you getting sound coming out from your pc to the headphones. Could that be causing the issue

Direct 3.5 to PC , Dac(3.5) , Dac(XLR) - VBcable(also tried VBhifi)
I tried that.
Even if use the same connection method, use the same file, or set the same settings, other computers will work. It works even if the window version is the same.
This is mystery.

This looks wrong.
Did you put the txt file and the wave file somewhere in in the config folder of EQ-APO. Other folders sometimes do not work.

If i single-convolve the wave file you gave me

But this is way you do not get the correct channel mapping.

Sorry. My fault. Invalid character entered in folder path. The response now appears. Side and rear are muted as expected, and front and center can be heard behind my back.

I will no longer go against the topic of the thread because I am convinced that this is no longer a matter related to Brir or Hesuvi or APO. I'm sorry.
Even if very few users, including me, didn't use brir, there were times when Windows's virtual 7.1 didn't work properly, and there was no solution to this even after searching deep to the bottom of Google. Also, since I tested my surround sound properly today while testing with multiple PCs myself, I can think of it as a compatibility issue for my PC at the moment. Of course, because it works again on other PCs using the same motherboard, I can't find a CPU and motherboard that works until when, so I decided to abandon the virtual approach.
Another user recommended me to physically route and I'm trying to buy and try next time. (Denon4800h+Motuai24 for Channel Routiing)

I think this is very unlikely. So there is one test you could try. The EQ-APO benchmark allows you to save wave files processed with your configuration. You could convert a 7.1 file this way and listen to it on another device (smartphone).

Are you testing with the other computers at exactly the same spot and looking at exactly the same thing? Different spot and view will give your brains different cues for localizing the sounds.

I think a lot of people are talking about the perceptions.

I am also interested in your answer to jaakko's question about seeting position and what you are looking at. Maybe you don't realise how much these things can influence your perception.

The EQ-APO benchmark allows you to save wave files processed with your configuration. You could convert a 7.1 file this way and listen to it on another device (smartphone).

And if he creates one such file on one system that "works correct" and one such file on the system that "doesn't work correct" (using the same 7.1 source file of course) then he could do a file compare (or a null-test): if they turn out to be identical files then we know it is a perception issue (or a difference in the rest of the playback chain). And if there is a difference between the files (in the actual audio data, I don't know if there can be additional data - like meta data - that could be different) then there is really something else going on.

I've already tested on different PCs, different devices with the same file... I thought this was impossible, so I initially suspected problems such as my own setup or a lack of proper installation.

On a device where this works properly, it sounds like that in the right position I marked. It's not what I feel, it's what I hear it........ =(

And if my current PC or the PC I tested doesn't work the same as my computer, the front and center are at the back as I indicated. It sounds like it's coming from behind, but it's not. It's in the back Just.

Two-channels work very accurately. So the problem is that Windows itself 7.1 doesn't work normally on some computers, including my computer.
It's not a problem with the file. Weird placement of sound in windows.
I also wrote because you replied, but as I wrote yesterday, I will no longer deviate from the topic of the thread. I'm sorry.

It is clear to me that you don't understand what I say. Hearing perception - or simply: what (you think) you hear - is a construction by the brain, the actual sound is just one part of the information the brain uses for that. (Do you know for example the McGurk effect? )
Or in other words: what you hear is not fully determined by the actual sound.
Visual (and other) cues can - and in daily life often do - overrule the hrtf related cues in the actual sound. If in one setup you are looking at a pc screen 50 cm in front of you, with a wall directly behind it your brain will very likely interpret the exact same sound very differently compared to sitting in the middle of a room, seeing a tv and loudspeakers at 3 meters distance in front of you.
That doesn't mean that there couldn't be something else going on, but the above is a very real possibility and hence our question about seeting position and what you see is really relevant. And on topic in this thread.
