This is where the CLIO Pocket comes in handy. Again, if you do speaker work daily, it s only a one-time inconvenience. measurement might be several hours or more, with the measurement only taking a few seconds, but a lot of preparation and debugging prior to that. One day, he will figure out what he would like to be when he grows up.
His professional research interests have spanned theoretical physics, electronics, chemistry, spectroscopy, aerospace, biology, and sensory science. About the Author Stuart Yaniger has been designing and building audio equipment for nearly half a century, and currently works as a technical director for a large industrial company. Figure 2: The screen shot shows the impedance phase of the tweeter measured in Figure 1 and simultaneously acquired. This is a remarkably flat impedance curve. So the time breakdown for doing a Figure 1: The screen shot of the impedance magnitude of AMT tweeter was acquired via the CLIO Pocket. Warning: The first time performing a measurement (or the first time in a while) means a very steep learning curve looms ahead.
On top of that, most of the preferred software options seem to originate from outside the US 8 December 2015 ΔΆ and England, so you have the triple-whammy of complex operation, manuals written in the turgid and opaque style of software engineers, and somewhat idiosyncratic English in the manual and in some of the menu commands.
(For example: When I did this six months ago, I remember using that command, where the devil is it? or I forgot how to load the microphone calibration files, let s read through the manual again, etc.) This is sadly not trivial since the most versatile software is by definition bloated with rarely used features, which means lots of menus and dialog boxes to try to dig through to find what you want. Oh yes, and re-familiarize yourself with the acoustic end of the measurement software. Then dig out the various speaker-specific bits, set everything up, and verify the operation each time. If you re not one of those fortunate people who can dedicate most of their time to speaker design and construction (and I m not), then you have to hunt up the loudspeaker, the cables, the power amps, the jigs, an external sound card, a stand to put the speaker on, a test microphone, and a microphone preamp. Instead, I operate out of my cellar electronics lab. I look with envy on the photos from folks such as Joe D Appolito, who have dedicated speaker labs or those who can set up measurements in a living room.
That s nice and simple in theory, and simple in reality if you are a dedicated speaker guy who doesn t fuss much with anything else and can leave things set up. Typically, we set up the software, adjust the levels, hit Go, and the measurement appears.

By Stuart Yaniger (United States) Photo 1: This is an improvised microphone mount adapter and shock mount made from torn cloth strips, mounted on a flexible tripod. So why my interest in the CLIO Pocket, given that I already have three sound cards and four software suites to support them? I was curious.
Until now, my series on using sound cards for audio measurement primarily concentrated on electronics rather than loudspeaker or acoustic measurements, but the current generation of sound cards and software can provide a variety of loudspeaker measurements. 1 Sound Cards for Data Acquisition in Audio Measurements (Part 7) Pitting the CLIO Pocket Against a Sound Card I admit to being intrigued by Joe D Appolito s review of the CLIO Pocket the junior version of Audiomatica s well-respected CLIO systems.
