very interesting! I didn't know that after the impulcifer measurements you can still have channel unbalance, i will try too after done my personal hrir
The only package used is SoundFile. You can run "pip install SoundFile" to check if you have installed it.
Good luck, hope you get good results. Keep a track of what you tried and what worked for and let us know
will i have to repeat the recording of the hrir most of the time or some of the impulcifer functions are post recording? i'm trying to think about how i should prepare the working area, hopefully i will not have to do the recording and turn around many times
Whilst recording you will need to turn your head. I’d recommend a few in one go. Each time you complete the recording save the folder somewhere else, delete the recording, adjust a little (change volume, push the mics a little further, change speaker position a little closer/further away) and do another recording.
i already installed impulcifer a while ago to try to cut some reverber in some hrir but i didn't like how it sounded, in fact my only concern about my future hrir recording is "how much reverb i will have?", i was even thinking to buy some acoustic foam to help reduce the eventual reverb lol but too much money so whatever
You can reduce the reverb with one of the balance options it worked really well for one of my measurements in the past.
I was getting similar graphs and my volume was way too loud. I set mine to just above normal loud listening and set the gain on both mics to just about below where they were clipping. Both mics had a slightly different gain setting.Hi, firsts tests, first measurement - stereo -, i've got a warning FT measurement has lower delay to left ear than to right, 1,8125... But everything seems correctly set up : i'm using a zomm H5 for input, the test signal is heared on left then on right, on headphones or speakers. Any idea ?
I've tested with Dire Straits Sultans of Swing, when i activate in Hesuvi, i loose all reverbs on guitars.
if both mics have different gain does this mean that you have to lower the gain on one of the two? then how can i understand the exact gain to balance both the mics?
It's likely that you reversed the left and right mics. When the right speaker is playing, sound should arrive earlier in the right ear than the left. That's what the warning means.
Humm yes, i didn't checked that perhaps on zoom H5, the input 1 not corresponding at L channel, i will test that.
Ok i switched the mics, but i still have the warning, but the delay is lower, 0,29 ms. The plots are very similar to the first one, i decreased the levels. First listening, the lower delay has a impact: there is something here, this far from perfect, but that the very first time i have no more the feeling that the sound with the headphones is in my head, neither around the head but almost coming from my speakers that are mute. No virtualisation (dolby headphone, ooyh and others) never gave me this feeling, I understand now the benefit of personal HRIR. Still have a lot of work to make it better but it's a good beginning.
