Amazing, gotta try this when I've got some time.....bookmarked in reference to your binaural mics. I already have the UMIK. Does it matter much if the speakers you do the testing with, to derive your HRTF, does it matter much if they don't go down to 20Hz? I mean can you extract the HRTF from the measurements in a somewhat smoothed & interpolated "average" fashion so that you can make sure you're not importing room mode issues and speaker limitation issues?Just an FYI for anyone interested in Impulcifer, I've been using it for over a year, and highly recommend it, if you are motivated. My hesitation has nothing to do with what it's capable of. For me it's beyond amazing, literally a dream come true. The illusion of extremely high quality speakers 8 ft in front of me is nothing short of stunning. Magical, really, next level. If you have the inclination for some DIY, have or can buy the modest equipment, can handle using command lines with numerous options, and the patience for some experimentation, the potential rewards are better than you imagine. Of course, HRTF's are personal, and I did probably a dozen measurement sessions, with several times that many trials of using different combinations of command options and EQ tweaks, until I hit the HRTF that totally changed how I listen to music. And it's much better than the sound of my speakers in my room. All the flaws have been fixed. I can't say it's the best sound you've heard, but it's the best sound I've heard in decades of searching for great sound.
"Think of headphones that mimic the sounds of the best studio in the world." - My experience exactly. I often feel like I'm sitting in the recording session, or in the 1st row of the concert. If others could hear what I'm hearing Impulcifer would be getting far more recognition.
