Amendment regarding Figure 5 in the previous: I realize that I had had already done loopback multi-tone measurements on the MOTU M2 revealing excellent multi-tone distortion performance exceeding what is needed for transducer measurement, whereby though it was perhaps fair to measure AC noise or...

I had actually recently troubleshot the origin of the spurious 60 Hz mains noise to little more than the unshielded part of my in-ear mics, whereby even if completely driven off of my laptop, the tone would still show up on the RTA FFT, being expectedly highest near my desktop, diminishing...

The transient response can be deduced from the impulse response which can be obtained from the Fourier transform of the magnitude and phase response. Room EQ Wizard makes it pretty easy to retrieve that transient response or go the other way and calculate the magnitude and phase from a direct...

You folks have quite some ears. The best I got for the title test a few hours ago was -48 dB with an EQed Meze Elite (which I had already measured as having exceptional multi-tone distortion; looking at FFTs of the Klippel test signal, it seems like BI multi-tone distortion is the closest in...

From the smoothed FR comparison in https://www.techpowerup.com/review/hifiman-susvara-unveiled-flagship-planar-magnetic-headphones/5.html with the modal parts matching up, I wouldn't be surprised if the Unveiled had just as poor resonances and CSD, its merely being a more sensitive version with...

Well, I made myself watch CMA's Ideon Absolute DAC "review" and found myself rather pissed to learn it was little more than a ridiculous maxing out around a "mere" ES9038PRO while I sit here content with two of those and the linear power supply in my FiiO K9 Pro ESS.

I shared my own short encounter with this headphone in https://www.head-fi.org/threads/yamaha-yh-5000se-—-a-flagship-from-an-orthodynamic-headphones-veteran.964970/post-18199782 (post #1,615) where I attribute a bizarre amplified vocal dynamism effect to the spiky response. I otherwise can...

See https://www.head-fi.org/threads/meze-audio-elite-the-new-isodynamic-hybrid-array-headphone-official-thread.959445/post-17743502 (post #5,152) and https://www.farnell.com/datasheets/1653468.pdf. These mics have surprisingly low distortion, but at least my pair were poorly matched, and the...

Funny enough, per https://www.head-fi.org/threads/recording-impulse-responses-for-speaker-virtualization.890719/page-121#post-18027627 (post #1,812), APL Virtuoso at least as run within Reaper was actually one of the worst for my ears at least when simulating rotations considering that I...

Indeed, if I am interpreting my own MOTU M2 measurements correctly (plus apparently impressively low-distortion $4 electret capsules), my current setup could resolve down to 80 dB SNR with averaged harmonic distortion sweeps and up to 90 dB SNR with long multi-tone FFTs, which is surely well...

I have yet to try Impulcifier, but I am likely to skip over that into implementing a more direct way of capturing HRTF directions without any special SOFA standard normalization, precomputing measured headphone compensations and baking those into the HRTF file, and perhaps allowing selection of...

Yes. I had linked https://www.head-fi.org/threads/anyone-into-crossfeed.961533/post-18068536 (post #78) earlier, but had forgotten to direct folks to the second part of that post covering CroPaC and Reaper (the first part was a foobar2000 bs2b tutorial). That CroPaC tutorial assumes usage of the...

Yeah. In https://www.audiosciencereview.com/...out-headphone-measurements.18451/post-1956895 (post #1,210), sitting still for three minutes straight to capture and average eight 4M length 192 kHz sample rate sweeps and hoping the measurement didn't get messed up wasn't fun, though my new in-ear...

I remember foobar2000's Crossfeed plugin ("component") being of the sort that felt like a mere slider between stereo and mono, thus compromising clarity, whereby it was only when I tried the linked bs2b (which albeit also incurs a volume level offset) that I finally got a then more convincing...

The second part of https://www.head-fi.org/threads/anyone-into-crossfeed.961533/post-18068536 (post #78) is a free way to get a taste minus the head-tracking; for clarity, I prefer trying to simulate the anechoic sound with outdoor measurements and upmix in further than at-home practical first...

Would you share how you measured the loudness of your listening? For me, in my link featuring multi-tone measurements, I devised a way to mount my in-ear microphone capsules in an SPL calibrator, first set my amp's volume knob for the given piece to what I considered "concert levels", then...

I am also of the stance that "soundstage" heavily depends on the individual's susceptibility to certain audio queues. Some folks can hear a big difference in "wideness" between something like the HiFiMan Arya Stealth and HiFiMan HE1000se while for me, image width and all are expectedly identical...

I'm guessing the "you" here is rather referring to Amir. Anyways, in a world where I find that my Arya Stealth and HE1000se have similar tonalities and neither impresses me more, driver matching and distortion measurements end up being the main places for me to see if there is a sliver of...

It is interesting that a number of others have the opposite opinion that FR measurements are the most important and that most THD results are barely audible anyway. I care about ease of EQing (smooth frequency response throughout) and not incurring too much distortion from raising any parts that...

Maybe removing the grilles will clean up some treble nulls or other roughness. Otherwise, for this price, I would expect a properly perfected planar driver with exquisite diaphragm installation precision and QC and hence markedly improved distortion performance and control of resonances. At...
