Headphone Measurements: The New Standard, Part 1
To add a little bit more perspective on the measurement of headphones. An ear simulator is not the only means of measurement of a transducer. Some others looking at what a headphone response is are similar to traditional loudspeaker measurements just scaled to size. Unloaded near field response...- pfzar

Headphone Measurements: The New Standard, Part 1
My 2 or 3 cents. This new 5128 is a tool, just like the other mics, analyzers, and meters we use for tests. We have a lot of new work to do with this new tool to shape our ideas. The pursuit of knowledge of a topic often leads to having to reevaluate our understanding. Just because we can...- pfzar

Testing audiophile claims and myths
HRTF's are measured in a few different ways. Blocked meatus, meaning the microphone is placed in the concha bowl, the entrance to the ear canal, or DRP the Drum Reference point. KEMAR/HATS, or a probe mic, meaning the microphone is placed at a depth relative to the eardrum. These two methods...- pfzar

Headphone Measurements: The New Standard, Part 1
I wouldnt characterize the inner ear as Psychoacoustics. The inner ear is transfering vibration into the electrical signals.- pfzar

24bit vs 16bit, the myth exploded!
WHAT? Man, this has been interesting to follow. Certainly a lot of theories going on. I think there a lot of scientists rolling over in their graves.- pfzar

Testing audiophile claims and myths
Reminds me of so many times in the music industry working with singers. I need more reverb or more EQ. Touch the wrong knob. Turn the back and forth. Is that good? Perfect. On we go.- pfzar

No. You are not comparing a DAC to a DAC you are comparing the sum of all the parts to another. In simplified terms. Both DAC's have a power supply and an analog output section. The power supply is a source of noise for both the Digital and Analog sections of a PCB. The Analog output...- pfzar

What creates soundstage in headphones??
I suggest those in the debate read a few papers regarding spatial hearing. L. Rayleigh, (1907). "On Our Perception of Sound Direction," Philosophy. Mag., vol. 13 Blauert, J. (1969-70). Sound Localization in the Median Plane, Acustica, Volume 22, pp. 205-213. J. C. Middlebrooks, E. A...- pfzar

What's the point that you are trying to make? Yes, a Bessel filter vs Sallen-Key Filter will do different things. But as stated. 1s and 0s are the same.- pfzar

HDMI is not the issue in the case of a film being correct. The problem is the TV and its ability to reproduce the colors and dynamic range correctly. The image has to do with the panel, its technology (LED, OLED, Plasma, etc.) panel yield, and controllers for the said choice of technology...- pfzar
