100+ Head-Fier
Ah understood about the flat target. I still don't get why it sounds better and more natural to me - I just have to reduce the 4000hz attenuation and it's virtually there for me.
Yep - I'm copying the eq.wav and doing the headphone compensation then. I guess I got it the wrong way round - will try again tomorrow.
Edit: the balancer issue was user error - I compensated the wrong headphones. The center image is slightly tighter with just the stereo recording. Would it be an idea to run the balancer per speaker?
I'm thinking of running balancer per speaker pair, so FL+FR, FC, SL+SR and BL+BR.
How much do you attenuate the 4 kHz and how wide filter? Are you using this on top of Impulcifer's headphone compensation?
Ok, that explains why I don't hear any difference. Actually this sound already very close to the real speakers in the room. But the funny thing is that I did only one test measurement before and that this was the first real measurement with Impulcifer and I had trouble with the microfon (Pui 5024HD capsule with XLR plug working at approx. 4V) placement in my ears. I hope I find time in the weekend to do more measurements. I have also put together a second microfon working at 6V and a microfon with the 3,5mm plug (but this looks a bit noisy). Actually I only measured with my HD 555 and I also want to test my AKG 701.
Very cool. Could you show us your mics? The capsule looks very good specs wise. -24 dB sensitivity and 14 dB noise. This is essentially better than Primo EM172 and more readily available and cheaper. Too bad it's 10 mm capsule although I'm not so sure if that's that bad thing because my current mics are 9 mm with the silicone casings and the cable is going to be the biggest problem anyways when trying to insert the mics exactly at the ear canal opening.
I asked if FEL Communications (micbooster.com) could provide stereo EM 258 modules with matched capsules. They agreed to do it on request and use the thin Mogami microphone cable. So this but stereo: https://micbooster.com/primo-microphone-capsules/97-primo-em258-mono-module-with-35mm-plug-10m.html. They also were kind enough to tell me which adapters I would need to connect such a stereo module to an USB audio interface with two RODE VXLR+ phantom power adaptors: https://www.amazon.co.uk/Plated-Copper-Female-Stereo-Adapter-0-9-Meter/dp/B0785VKZW4/. This is my current best guess for a high performance binaural mics without too much DIYing. Of course one needs to glue these capsules to ear plugs but that can hardly be failed. They also have the molding putty for this specific purpose: https://micbooster.com/microphone-holders/112-lugguards-custom-moulded-earplugs.html
