    The Top 10 Things That Can Never Be Taught Often Enough In Audio
    pro audio
    Karl Winkler 05/08/12 04:49 PM,
    10. Musicians feel most comfortable and play best when they hear what they need to hear on the stage. Of course, the experienced monitor guys and recording guys already know this. But it’s something for those less experienced to think about. No, it’s not about how much power you have or what kind of monitor wedges. It’s about psychology. And I think it’s true that if you become good at monitors and understand how to please musicians, you are 90… View this post

    Factors Defining A “Good” Sound Reinforcement System
    image
    Bob Thurmond 05/07/12 06:23 PM,
    How many sound systems have been built and 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 be? What is it we don’t yet understand? Do we even know enough to know what we don’t know? Perhaps we should… View this post

  • Church Sound: Understanding Noise And Isolation In A Sanctuary
    worship audio
    Doug Jones 05/07/12 08:18 AM,
    Here we present a portion of a chapter in the book “Sound of Worship” by Douglas R. Jones, published by Focal Press. ———————————- Noise is a problem that every church must deal with regardless of its worship style or form. Noise is basically unwanted sound. It is important to realize that the definition of noise includes a subjective component. Noise is unwanted sound. Noise can be any sound that intrudes on someone’s space. It can be sound that in another… View this post

    Church Sound: Do You REALLY Know Your Channel EQ Controls?
    church sound
    Chris Huff 05/04/12 12:29 PM,
    This article is provided by Behind The Mixer.   You could potentially improve your mix quality by taking one little step: learning how the channel EQ controls affect sound frequencies.  They may not work like you expect. Turning Knobs I recall seeing the EQ knobs labeled “High” and “Low” as I looked upon the sound board during my first time mixing. “I know what those mean,” I thought. “I can increase or decrease those high and low frequencies.” I was… View this post

    Church Sound: Amplifying Child Vocals In Productions
    church sound
    Bruce Bartlett 05/03/12 10:55 AM,
    This article is provided by Bartlett Microphones.   Perhaps the most challenging sound-reinforcement job—in terms of feedback—is amplifying children. It’s often hard to hear children in dramatic or musical productions. That’s because most children don’t project. Since they produce a low volume on stage, you must turn up their mics a lot to hear them—resulting in feedback. Here I’ll offer some creative solutions to help those young voices be heard. I won’t cover wireless mics—even though they work well—because they… View this post

    In The Studio: Mic With Your Ears, Not Your Eyes
    image
    Bruce A. Miller 05/02/12 03:46 PM,
    This article is provided by BAMaudioschool.com.   Often, a young engineer will start to position microphones based on what they see done by others or read in a magazine.  Sometimes they experiment and move the mics to see if the sound improves, but usually once someone ends up with a mic setup they like they stop trying to improve it. There are certain standard approaches that have been successful, but even these approaches should never be considered “etched in stone”. … View this post

  • The Audio Expert: Audio Fidelity, Measurements, And Myths—Part 1
    audio
    Ethan Winer 05/02/12 10:21 AM,
    Here we present a portion of a chapter in the new book “The Audio Expert” by Ethan Winer, published by Focal Press. ———————————- “Science is not a democracy that can be voted on with the popular opinion.” — Earl R. Geddes, audio researcher In this chapter I explain how to assess the fidelity of audio devices and address what can and cannot be measured. Obviously, there’s no metric for personal preference, such as intentional coloration from equalization choices or the… View this post

  • When Eyes And Ears Don’t Agree: Perspective On The Role Of Measurement
    a/v
    Pat Brown 05/02/12 07:02 AM,
    In my previous article (here), I addressed some of the caveats of measuring sound fields in enclosed spaces. The conclusion was that the eyes and ears do not always agree when it comes to sound quality. 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… View this post

    Understanding Wireless: RF Output Power
    wireless
    Volker Schmitt & Joe Ciaudelli 05/01/12 04:26 PM,
    Using radio frequency (RF) wireless microphone transmitters with the right amount of RF output power is important to ensure total system reliability. There is a common misconception that higher power is better. However, in many applications high power can aggravate intermodulation (IM) distortion, resulting in audible noises. First, the applied RF output power must fall within the limit allowed by each country’s legislation. In the U.S., the maximum RF output power for wireless microphones is limited to 250 mW. In… View this post

  • In The Studio: The Basics Sound & Acoustics—Timbre
    recording
    Los Teignos 05/01/12 02:27 PM,
    This article is provided by Audiofanzine. Timbre is a sound’s identity. This identity depends on the physical characteristics of the sound’s medium (the matter or substance that supports the sound). Let’s take an A at 440 Hertz produced at 60 decibels: we can immediately tell if the sound was emitted from a violin, saxophone, or piano. Yet, even though the instrument is different, it’s the same note and the same amplitude. The difference is in the sound production: string, air… View this post
