    This article is provided by HX Audio Lab   Electronic correction in the form of Equalization (EQ) is one of the most useful audio tools for loudspeaker compensation/correction, whether it compensates from non-linearities in the loudspeaker or for altering the effect of room acoustics. Two audio filter types are typically used: IIR and FIR. IIR stands for Infinite Impulse Response and FIR stands for Finite Impulse Response. Each has its own pluses and minuses. This article intends to introduce key… View this story

    What is impedance? Impedance is the AC (alternating current) version of the DC (direct current) term resistance, which is the opposition to electron current flow in a circuit and is expressed in ohms. Impedance (often abbreviated as “Z”) includes capactive reactance and inductive reactance in addition to simple DC resistance. Reactance depends upon the frequency of the signal flowing in the circuit. Capactive reactance increases as frequency decreases: inductive reactance increases as frequency increases. Because of this frequency dependence, impedance… View this story

      The eyes and ears do not always agree when it comes to sound quality. (Related article here.) If making acoustic measurements is so difficult, why bother? Why not tune the system based solely on listening? Because there are several very good reasons for including our eyes in the system tuning process! We humans base our concept of reality upon the evidence presented by the five senses to the brain. Our concept of “blue sky” or “green grass” is the… View this story

    “I’m going to equalize the room.” We’ve all heard that statement so many times that we scarcely think about what it literally means. We know that in practical terms it means adjusting an equalizer to suit your taste. It may be done with the latest high-technology analysis equipment, voodoo magic or simply tweaking away “until it sounds right.” In any case, are we really “equalizing the room”? What exactly are we doing? There are lots of disagreements on this topic… View this story

    This article is provided by Bartlett Audio.   Microphone choice and technique have a powerful affect on the amplified sound of a reinforcement system. The sound picked up might be “natural,” “boomy,” “thin,” “colored” and any other number of descriptive terms that are applied to a sonic signature. It’s usually most desirable to attain “natural” sound. But what does that mean? I define it as the tonal balance heard with our ears in front of a musical instrument, a few… View this story

    This article is provided by L M Watts Technology   I’ve always admired ribbon microphones, having built them in my high school years from gum wrapper foil, surplus magnetron magnets, and filament transformers. Much Later after research and design engineering stints at Shure, Electro-Voice, and other places I wanted to add a ribbon mic to my new microphone company. But I wanted something a little different from a standard figure 8 design. I was fascinated with the multi pattern/non figure… View this story

    Adele is currently playing to sold-out arenas on a world tour. The elaborate sound needs require a constant focus on the singer and her voice. Acoustic effects are paired with consummate style during the entirety of the show. To meet the high expectations of audio perfection, the engineering team relies on the new beyerdynamic TG MM1w interchangeable measurement microphone capsule to accurately test audio levels with the benefits of its ease of use. The performance utilizes sections of both stage… 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
