Sounds good! I find interesting that you use free field HRTF since that's often perceived to be too bright having no tilt. What's your take on that?

If all speakers are equal distance from the center of the head, the delay from different angles arrive at the ears ever so slightly different times. Impulcifer adds these delays intentionally.

Someone here should start making open ear canal microphones and selling them. Using as small capsule as possible with a some kind of fitting or clamp to keep the capsule in place at the center of the ear canal opening. Currently the biggest problem with Impulcifer is the headphone compensation...

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. If you measured 7 channels, then the HRIR doesn't contain a source that's directly behind you...

You can also put a cardboard box in front of you and draw speaker drivers on it and then listen to it the center channel. This might trick your brains into thinking the sound comes from the "speaker" and so make it sound like it's coming from in front of you.

It could be visuals affecting your perception of the sound instead of anything technical. If what you hear doesn't match what you see, your brain gets confused and one possible outcome could be that you hear the center coming from behind you. Brains tend to default sounds being perceived coming...

Headphone type doesn't generally matter. Planars will work just as well as dynamic headphones.

Latency will probably ultimately kill this idea in practice. I've hear head tracking for audio requires sub 10 ms latency to work well and there probably isn't a way to achieve that without real time kernel.

I'd love to see this come be and I've toyed with the idea of building it myself but probably won't be have time any time soon. Head tracking would be superb and I would definitely make Impulcifer be able to record more angles to support this if anyone would build or find an existing solution for...

For over-ear headphones it's 6 dB and it's on top of a target that doesn't have bass boost and so matches Harman target.

I if it looks and sounds right then it's probably right. You could have also done this simpler by adding something like this manually to sound signature box frequency,raw 20,0 700,0 1270,2 2300,0 20000,0

AutoEq is a project for automatically equalizing headphones. While this project is now familiar to many people engaged in headphone hobby, it has always been a bit of a pain to use if you want anything else than the pre-computed presets. autoeq.app is a web app using AutoEq but now with a...

Location of the first positive or negative peak of at least -12 dB in the impulse response.

I'd say yes since anechoic chamber will sound drastically different than a regular listening room for which the content is produced for.

The profiles are based on frequency response measurements. You can't do those realistically yourself. /u/oratory1990 in Reddit has been measuring (at least in the past) headphones people send to him so you could contact him to ask if he'd be willing to measure your pair with the pads you have...
