There's more to measuring loudspeaker driver and system impedance than simply setting up a measurement and acquiring data. This video tutorial will teach you how to measure loudspeaker impedance within its linear region. The background presented in previous impedance measurement tutorials lay important groundwork and are highly recommended. Watch this tutorial to find out what you may be missing in theSoundscapes Resources area. Please be sure to read the comments under each video for important notes.
Audiomatica's new release of CLIO 12 in both Standard and QC versions is a game changer for the electroacoustic measurement market. Not only has the hardware interface changed to USB2 for out of the box compatibility with virtually every PC on the market, but significant software upgrades and a fresh new look for both versions make the upgrade especially enticing given the fact that the pricing remains the same through September! CLIO 12 systems are in stock now and significantly discounted upgrades for current CLIO FW owners are available now - contact us for details!
One of the most interesting things I've learned from making theYouTube Video Tutorials is the huge amount of interest in audio measurement around the world. In less than 6 months after the first video was posted there were over 2,000 views from 54 countries! This is humbling and amazing and it became obvious that I needed to find a safe, easy, fast and inexpensive way to ship CLIO and a growing list of world class measurement tools outside the boarders of America. The good news is that I have found ideal solutions for those that regularly purchase from the USA and those that do not. I am excited to announce that sales world wide is now available. Please see our International Sales page for details.
While it has always been very easy and inexpensive to add a FireWire card or adapter to desktop PC's and Mac's, Intel's recent USB Type C / Thunderbolt 3 port now makes laptop FireWire just as easy and reliable as the desktop!
The reactive components involved in passive electrical crossover networks used to control the acoustic output of loudspeakers are the focus of this video tutorial. The background presented in the previous resistor measurement tutorial lays important groundwork and is highly recommended.

The simplest component involved in the passive electrical crossover networks we use to control the acoustic output of loudspeakers is the focus of this video tutorial. A grasp of the theory behind resistor measurement is foundational to understanding the more complex concepts of capacitor and inductor reactive impedance.

Nothing is more frustrating than going to the trouble and expense of setting up and executing a one-chance measurement and finding out later that a few simple gain adjustments would have yielded a far better data acquisition. The principles of setting up proper gain structures are often overlooked to our detriment. Watch the fourth video tutorial and find out what you may be missing in theSoundscapes Resources area.

The concepts of FFT bins and Windowing are introduced to help users avoid common pitfalls in making classical THD measurements. Well worth the watch even if you don't make single frequency measurements and can be found in theSoundscapes Resources area. Please be sure to read our comments under each video for important notes.
The first of a continuing series of video based tutorials to acquaint users with the fundamental concepts of audio measurement can be found in theSoundscapes Resources area. After receiving requests from both users and manufacturers alike, Soundscapes has responded using YouTube as the principle delivery method. Don't expect scripted, rehearsed instruction - they are single take recordings that nevertheless seem to be well received. Comments and questions via YouTube or email are welcome. Please be sure to read our comments under each video for important notes.
Imagine traveling a great distance at significant cost to acquire measurement data for a project. Upon returning you find your data has been compromised by distortion that was somewhere in the system and you have to make decisions using this data. A new application note in theSoundscapes Resources area provides important information on how to easily recognize and avoid measurement distortion.
Have you ever wondered what difference adding additional mic cable length to your measurement setup would make? Or how a different cable or construction type might change the response? How about a different microphone using the same audio preamp interface? Or a different interface? Or placing a mic preamp near the mic and running a long cable from it to the audio interface? These questions and more are answered in a new Application Note that includes a downloadable spreadsheet calculator in theSoundscapes Resources area.
Another difficult choice made easy - the rugged Extech 407744 acoustic calibrator is affordable and built to last. Each unit is individually calibrated to beat factory specifications by an order of magnitude. Frequency accuracy ±0.5% of 1kHz, level accuracy ±0.08dB of 94dB with distortion products less than the reference Brüel & Kjær's Type 4230 calibrator. Price is no higher than you'll see on Amazon and elsewhere.This is the best deal in measurement microphone calibrators you'll ever find.
For years the audio industry has faced a difficult choice when it came to adding additional measurement systems to their inventory, (a) the expense of purchasing multiple copies of the primary system or (b), going with something less expensive with the hassle, incompatibilities and errors involved. Not anymore. The industry leading CLIO now has a powerful little brother: CLIO Pocket. Sharing many features with its larger counterpart, CLIO Pocket includes an extremely portable USB based hardware interface, measurement microphone and software for both Windows and Mac platforms.An easy choice and the price is unbelievable!
You'll meet two types of people in any industry you get involved with; (1) those who passively entered as they traveled their course and suddenly discovered they had to eat and do what they do for a paycheck, and (2) those who had a vocational epiphany. I'm the latter. This can happen sitting under a great teacher who ignites your soul with the fuel of his passion for his discipline and it can happen more subtly - when you're very young - as your Father opens the top of a long wooden cabinet - and turns on an invented machine with a revolving disc - that magically transports the Dave Brubeck band into your living room playing Take Five. Then you watch a fuzzy cathode ray tube in awe as the first man in history places his foot on another world. And like a fish that finds water, you find joy. Science as hydrogen. Music as oxygen. Covalently bonded inside of you.Musings is an irreverent look at stuff like this.
2016 Marks a brand new chapter in the professional life of Langston Holland, owner of Soundscapes. Over two decades of providing reference quality live reinforcement, installation and training combined with an insatiable passion for the sciences has opened a new door for his US based company. Audiomatica, the makers of CLIO, the single most powerful audio measurement system available has granted Soundscapes full distribution rights. CLIO now has a new advocate in the US market. To quote Holland:"While continuing to serve the performing arts and installation markets, our primary focus will be to equip and train the entertainment, manufacturing and research industries to make the best use of the best data acquisition and analysis tools for their needs."
