Recording Impulse Responses for Speaker Virtualization

[Kosorm]

You use Audacity?
Can you upload FL,FR.wav file? (original no edit)


You don't have to do anything.
If you only have FL,FR, you will mute the rest of the channel.

Here are the original files, thank you

I haven't checked it in REW, but it looks like clipping has occurred.
I think it would be better to reduce the gain and record it again.
And didn't you record FL,FR all at once?
Or do you measure it by turning around with one speaker?
And did you also measure the headphones?

Hmm yeah i see what you mean with the clipping now. This is how i recorded it:

First i inserted both of my in ear microphones, trying to get as deep and symmetrical as possible while still facing outward.

Then I put my headphones, executed the command that does one ear and then the other. After that I used a single speaker pointed directly at my chair from roughly 3-5 feet away.

I then used a protractor and string to direct my viewing angle 30° to the left or right for that particular measurement, and turned my chair to look that way. I took measurements of the 2 positions and did a room correction with a umik-1 with calibration in the center of the head with my chair facing the speaker.

From there i just processed everything.

Hmm.. okay
Download the 2 in this link and try moving or erasing the existing FL.wavFR.wav.
Put the processed Hesuvi in the Hesuvi folder.
There will probably be no execution errors.

Your FR I checked is like this.

The right speaker (RL, RR) doesn't seem to have a big problem.

But the L speaker is a bit unusual.
I don't know if it's because of clipping.

Thank you so much, i will try it shortly and report back

Hmm so if i add the file into eapo's convolver, it has that hissing white noise still, but when i try to add it into hesuvi instead of eapo it keeps repeating the last 2 seconds of music in each ear and sounds very not right. not sure what im doing wrong and google isnt helping. i definitely need to rerecord the channels tomorrow but i feel like there is another issue here that must be addressed

정말 감사합니다. 곧 시도해보고 다시 보고드리겠습니다.

covolution in apo does not read truestereo(such as BRIR has LL,LR,RL,RR 4ch).
So you have to use a different vst or make a command for truestereo yourself
That's why I use hesuvi to write comfortably.

I also attached your response to my previous reply.
When I looked at the impulse, I didn't think it would sound normal, but it was done with the impulcifier.

I'll let you know what you're going to do.

1. Avoid digital clipping.
: Clipping is currently occurring.

2. I wear the microphone more carefully.
: If you look at the FR I've attached before, it looks like there's a lot of hard data. I think the microphone might be touching the wall in your ear or something.

I see, that makes sense. Unfortunately hesuvi has all of the audio repeating over and over in each ear. Is this due to an issue in my recording or am i missing some setting somewhere?

Thank you for the updated response. Could the foam i added after taking the microphone casing off be causing this? Or is the microphone just too deep into my ear and being covered by my tragus? Thanks again for all the quick responses

I can't answer because I don't know how and how much your microphone is in your ears.

In my case, I recorded it like this.

I think there is more than 90% chance that there is a problem with the recording.


To figure out if it's a Hesuvi problem, there's a default preset that comes out when you turn on the Hesuvi program.
It's not correct because it's a public BRIR, but at least you'll be able to test the eco-like phenomenon you're currently experiencing.
I don't remember the name if it was DTS+ or something, but press anything.
If you press it and it makes a weird sound many times, it's a problem with hisuvi+apo, and those presets are not problematic, then your recording is wrong.

This is super useful info thank you. Ill try again in the morning and see what i am able to accomplish

The command in EQ-APO should look like this:

# L=Left ; R=Right
#Create virtual speaker channels
Copy: L0=L R1=L L1=R R0=R
#Mute Input Channels
Copy: L=0 R=0
#virtual channels that are filtered
Channel: L0 R1 L1 R0
#Folder of Convolution files complete folder name or if files in config "\...."
Convolution: C:\Program Files\...\filename.wav
Copy: L=L0+L1 R=R1+R0

 

[Kosorm]

Alright! So i took another thing of measurements this morning with all the advice given yesterday. For whatever reason Hesuvi still doesnt want to play nice but luckily the command given by musicreo works perfectly.

The new measurement is without that high pitched hiss and sounds a lot more like how i expected it to. That being said, i feel like there is a crazy amount of reverb and not much in the way of bass. It makes the music sound sort of like an unprocessed demo version of the mix for each song.

When i get home I'm going to attempt to change/fix some things, but for now here is my my_hrir folder if anybody feels like poking around to see what might have went wrong this time around/what i should fix with this recording.

Thanks again so much for the help thus far everyone

 

[musicreo]

Still might be doing it wrong but i tried throwing in the hrir.wav into eapo through the convolution with impulse response after manually swapping the left and right channels in both fr and fl.wav and for some reason i keep getting a loud white noise type hiss whenever audio is playing on my pc. this is my file anyone know whats happening? my hrir.wav

the hissing is entirely in my left ear

The left channel is very strange. At 0,7 sec there is again a signal in the left channel. This results in the repeating echo. You could cut this off and try the file again.

Yeah the new recording has no such issue thankfully when ran through the command you gave me (the old one did), but for some reason it doesnt want to play nice with hesuvi. Not a big problem though as your thing works more than fine.

New recording with less issues (but still some) here
