#FUZZMEASURE FRD ZMA MAC OS#
The requirement of Mac OS Yosemite may discourage some non-early-adopters I brought my own recent MacBook Air and a portable USB interface to The Bunker Studio in Brooklyn in order to run some tests. Paired with a computer (running Mac OS 10.10 or newer), audio interface, and measurement mic, FuzzMeasure can generate beautiful, high-resolution graphs (including especially nice FFT waterfall plots) and facilitate comparative analysis of different systems.ĭownload, licensing, and installation of the software was simple, and the user interface was intuitive enough that I was up and running right away, without any manual-reading.
While the need for this capability might be less pressing for the average engineer, producer, or studio owner, we may still benefit from having the tools to make some basic measurements.įuzzMeasure 4 allows us to measure and compare basic attributes like frequency response, group delay, and harmonic distortion, as well as a few more esoteric metrics with which I am less familiar - nineteen parameters in all. PE is recommending the little Behringer Xenyx 802 mixer (502 doesn't have phantom power?) as an inexpensive phantom-powered interface.For acousticians and those engaged in research and development, the ability to measure attributes of rooms, speaker systems, and audio circuits is obviously invaluable. Chris has WT3, a Dayton mic, and a Mackie mixer, so we're going to make that work, as well.
#FUZZMEASURE FRD ZMA HOW TO#
The HOLM thread tells how to convert its files to FRD format, and WT2 exports ZMA directly, so I'm just a few experiments away from having a bottom-feeder package working here. Pete has discovered that the one he bought doesn't have sufficient front-end attenuation to permit nearfield measurements without overloading, but that may be because he wants to maintain max S/N ratio and plays the DUT at high SPL.Ĭranked up HOLMImpulse again to show WiredGuy on Sunday, and it worked slam-dunk with the Fast Track Pro USB preamp. Pete B and Ken Kantor are looking at the cheap in-line phantom powered USB preamps. Geddes's SPEAK software is now free on his website, which he says will model lobes and nulls, but I haven't looked at that. Also, the program has no facility for handling CD horns/waveguides in the directivity features.
#FUZZMEASURE FRD ZMA DRIVERS#
I can't get it to save sessions correctly, though, so I have to re-enter the whole works manually if I exit the program, a PITA loading in the measured ZMA impedance (from WT2) and FRD response (from CLIO, with the header stripped) data for both drivers each time. I was able to get the eWave crossover in and accurately modeled. It works, but has glitches running on this platform which I'm working through with Bagby. I discovered that the ZilchLab computer has Office 2000 on it just as you remembered and am running PCD.
