On November 19 (this coming Monday), PreSonus will release version 1.7 of its Universal Control, a free update to the company’s control-panel software that offers a significant expansion of the Rational Acoustics Smaart measurement technology that is integrated into the Virtual StudioLive section. The update will be available for download at www.presonus.com/support/downloads. In Universal Control 1.6, PreSonus added Smaart Measurement Technology’s Spectra module to its Virtual StudioLive control/editor/librarian software for all StudioLive mixers, which is part of Universal Control. This…

Church Sound: It’s A Little Too Loud, But That’s… Good?!?
Gary Zandstra
11/05/12 12:22 PM,
A couple of weeks ago the sound operator and I were standing in the middle of the main sanctuary trying to decide if the overall level was too hot. We were also trying to understand why the stage volume seemed to be up significantly. As we were talking (actually almost shouting, so that we could hear each other), I asked, “Is that the acoustic snare I’m hearing, or the amplified one?” With the sound level meter showing peaks of nearly…

How To Find Problems That Degrade Performance In Balanced Audio Equipment Interfaces
Bill Whitlock
11/05/12 09:36 AM,
Previously I have explored the theoretical aspects of balanced interfaces and de-bunked the widespread myth that equal and opposite signal swings are somehow responsible for its noise-rejection properties. In this column, we will explain how to find most problems that degrade performance in real-world systems. The problems fall into two broad categories. The first is design errors in the equipment itself, most often the “Pin 1 problem” that couples shield current noise into the audio. The second is problems caused…

Emulating What We Hear: Performing & Using The Difference Measurement
Pat Brown
11/01/12 05:42 PM,
Human listeners are effective “comparators.” We are very sensitive to changes in what we hear. When comparing loudspeakers, we are most sensitive to differences between models or brands rather than similarities. This powerful analytical tool can be emulated in the world of test and measurement. I have long considered the “difference” measurement to be one of the most valuable tools available to the sound practitioner. The procedure involves: 1. Performing a measurement 2. Storing it as a reference 3. Introduce…

SynAudCon Emergency Communiciation Systems (ECS) Speech Intelligibility Workshop Update
Pat Brown
10/25/12 07:35 AM,
Last month, we at SynAudCon announced the Emergency Communication System Speech Intelligibility Workshop (ECSSIW), to be held in January 2013. Go here for pricing information and to register to attend. Here’s an update on how the event is shaping up. We’ve just returned from a site visit to the American Airlines Training and Conference Center. While there, Brenda met with the staff to work out logistical details. I sized up the AV capabilities in the auditorium, and built a Sketchup…

Church Sound: That Mic’s Too Hot! Microphone Sensitivity And What It Really Means
Chris Huff
10/18/12 03:46 PM,
This article is provided by Behind The Mixer. Microphone sensitivity becomes a topic of discussion as soon as it becomes a problem. I’d hazard a guess that most people don’t think about microphone sensitivity until the moment when a microphone picks up a sound that explodes out of the house speakers, to which someone says, “that microphone’s really hot!” The Definition Microphone sensitivity is the measure of the microphone’s ability for converting acoustic pressure into an electric voltage. The…

The Devil And The Auto RTA: Don’t Forget To Use Your Ears
Bennett Prescott
10/18/12 03:31 PM,
In my perhaps too frequent visits pro audio forums, I regularly read about weekend warriors who have just acquired their first DSP (digital signal processor) system controller and are seeking to understand how it’s auto RTA (real-time analyzer) function can help provide better performance out of their portable sound system. Invariably, the DSP unit is pressed into service for the first gig, a measurement microphone is attached, and some signal (usually pink noise) is run through the rig while the…

Subwoofer Arrays: Discussion & Analysis Of A Variety Of Bass Coverage Patterns
Jeff Berryman
10/18/12 01:46 PM,
We often describe bass as non-directional. This is because we’ve learned that loudspeakers much smaller than the wavelengths they’re radiating are normally non-directional, and we know that bass wavelengths are long - 20 feet at 55 Hz, for example. In reality, bass is just low-frequency sound that obeys the same rules as sounds of other frequencies. In these rules, all dimensions are proportional to wavelength. For bass, practical directivity issues arise because the wavelengths involved are so large. Some…

Auralex Introduces ProFusor II Fabric Wrapped Sound Diffusor
PSW Staff
10/12/12 07:50 AM,
Auralex Acoustics has introduced the new ProFusor II fabric wrapped sound diffusor, designed to address flutter echo without removing acoustic energy in the room or greatly changing the frequency content of the sound. Implementing ProFusor II diffusors can help can make a small space seem large and a large space seem even larger while also allow users to enhance the accuracy of critical listening environments and create a larger “sweet spot.” Ideal for use in residential theaters, listening rooms, concert…
