    EDITOR’S NOTE: This fine article was featured in the March 2004 issue of Live Sound International. We reprint it here in celebration of our 25th anniversary. How many sound systems are in use? Many millions, for sure, and they’re found in all types of venues and for all kinds of programs. So one would think we’d know exactly how to do it by now. But there seems to be plenty of examples to prove that we don’t. Why should this… View this story

    Currently serving as the director of Danley (Sound Labs) University, Doug Jones grew up in northeastern Congo, the child of missionary parents, and his feelings about his childhood experience are complex: the benefits — difficult to articulate — came at considerable costs. “It’s hard to know how to share my story with anyone who wasn’t a missionary kid,” he says. “And yet it is my story; it shaped who I am today.” Jones has long mused about the radical discord… View this story

    Editor’s Note: This article originally appeared in the November/December 2001 issue of Live Sound International magazine. ————————————————————- At the announcement of my children’s birth, the first thing everyone asked was “what did they weigh?” It always struck me as somewhat peculiar. Of all the personal qualities you could discuss, such as the color of the hair, or how healthy they are, weight seems a strange specification. Fancy telling somebody that you have just purchased a new car: “Oh really, what… View this story

    ProSoundWeb presents at least two feature articles every day of the working week, meaning that there are 40-plus long-form articles highlighted each and every month. That’s a lot. In fact, so much so that we thought it would be handy to present a round-up of the most-read articles for those who might have missed at least some of them the first time around. What follows is the top 5 most-read articles on PSW for the month of June 2016. Note… View this story

    Several years ago my company was hired to provide production for a fashion show in a ballroom. In advancing the show with the producer, the audio portion looked to be fairly easy, with just a few wireless microphones for the presenters and music playback provided by a DJ. Outputs were supposed to be the feeds to the left and right main PA stacks, along with a send to the video company recording the show. Add a board mic and our… View this story

    This article is provided by Rane Corporation.   You may have heard it said that equalizers are nothing more than glorified tone controls. That’s pretty accurate and helps explain their usefulness and importance. Simply put, equalizers allow you to change the tonal balance of whatever you are controlling. You can increase (boost) or decrease (cut) on a band-by-band basis just the desired frequencies. Equalizers come in all different sizes and shapes, varying greatly in design and complexity. Select from a… View this story

    Some of us may only have access to a limited microphone inventory in our day-to-day work, while others may have a wider range of choices. Regardless, most tend to stick with “go-to” favorites in terms of both mics and techniques. There’s rarely if ever the luxury of testing different mics and positioning at sound check, so we opt for what we know works. Amidst this routine, however, there are bound to be situations where a creative, unusual mic choice and/or… View this story

    This article is provided by EarLevel Engineering.   Here we lay the foundation. We’ll look at analog to digital conversion, and we’ll look at the spectrum of the resulting digital signal. We’ll use that knowledge to help understand the conversion process back to analog. Though we can build real-world converters that work as described, we’re not building practical converters here; we’re interested in the mathematical concepts involved and their relationships to digital signal processing. Analog To Digital Conversion The sampling… View this story

    “It turns out that, within very generous tolerances, humans are insensitive to phase shifts. Under carefully contrived circumstances, special signals auditioned in anechoic conditions, or through headphones, people have heard slight differences. However, even these limited results have failed to provide clear evidence of a “preference” for a lack of phase shift. When auditioned in real rooms, these differences disappear…” – Dr. Floyd Toole As Dr. Toole states, a lot of people, including myself, have a hard time detecting phase… View this story

    This article is provided by Rane Corporation.   This paper discusses the pitfalls (often subtle) of our industry’s failure to define and standardize what “unity gain” means, and the conditions necessary to measure it. It further discusses how people improperly use one piece of misinformation (impedance matching) to correct for this lack of standardization. All done, without knowing discrepancies exist between different pieces of equipment, and without knowing impedance matching is unnecessary, signal degrading, and wasteful. For me, it began… View this story
