    Powersoft has announced that it is sponsoring the multi-platform PAcalculate app, which runs on mobile devices such as Android, iOS, Windows-Phone, Blackberry — including smartphones and tablets. Developed by Brusi Acoustics, a consulting firm for electroacoustic and an independent laboratory for loudspeaker directivity testing, it is marketed by Doctor Pro Audio. This multi-lingual app (currently speaking Simplified Chinese, English, French, German, Italian, Portuguese, Russian and Spanish), contains many calculations, utilities and reference information. It is therefore a useful tool for… View this post

    As with the ever-ongoing debates about “tubes versus transistors,” “analog versus digital” and “Mac versus PC,” there’s not likely to be agreement any time soon about “objective versus subjective” when it comes to sound quality. Extremists in the “Objectivist” camp argue that, “if it can’t be measured, it doesn’t exist” while on the other hand, the “Subjectivist” side firmly backs the idea that “human beings can hear things that can’t be measured.” How often has it been suggested, “use your… View this post

    Editor’s note: This article originally appeared on PSW in 2012, however the information is still quite relevant and worth revisiting. I’m asked a lot of questions about sound. Many of them focus on unraveling and understanding some particular function, feature or concept, while others are directed toward distilling my opinion on methods or industry trends. A while ago. I was asked some questions that led me to some in-depth pondering. The questions: Why are line arrays so popular? Are they… View this post

    lsi demo
    PSW Staff 10/06/16 11:12 AM,
    The recent Live Sound International Loudspeaker Demo at the Kentucky Expo Center in Louisville during the annual Worship Facilities Expo (WFX) drew hundreds of audio professionals and church sound personnel over the course of its two-plus-day run. The demo, which launched six years ago at WFX in Dallas, delivers unique side-by-side listening opportunities to evaluate top line array and loudspeaker systems in a round-robin format. This year’s event kicked off with an evening slate of sessions for the regional pro… View this post

  • impedance
    Jonah Altrove 10/06/16 08:42 AM,
    It may not seem so at first blush, but there are a few concepts as pervasive in live audio as the concept of impedance. It’s relevant to microphones, direct boxes (DIs), preamps, processors, amplifiers, loudspeakers, equalizers, crossover filters, and even the cables that connect them all together. In this article we’ll explore the principles of impedance, and examine how these concepts apply directly to our work in the field. Ohm Sweet Ohm In order to understand impedance, we need to… View this post

    subwoofers
    Pat Brown 10/05/16 07:27 AM,
      Suppose you bought the best subwoofer that money can buy. Its response is amazingly smooth and extends down to 20 Hz. You hook it to your power amplifier with automotive jumper cables, and warn the neighbors to make sure that small children and pets are indoors, because you are about to do some serious low-frequency listening. You fire the system up and insert the DVD test disc, the one with low-frequency sweeps that allow the smoothness of the system’s… View this post

    church sound
    Gary Zandstra 10/03/16 02:25 PM,
    This article is provided by Gary Zandstra.com.   Sitting in the tech booth during a service on a recent Sunday, I had an “a-ha” moment. Not a big one, but still a good lesson. We had traded worship bands for the day with our sister church. Our band was playing at their place, and vice versa. One of our front of house people, Justin, traveled with the band to do the mixing. Just as our service began, I received a… View this post

    Back in 2012, Ultra Worldwide, producers of the Ultra Music Festival in Miami, launched a new event concept appropriately named ‘Road to Ultra’. The journey unfolded through Thailand, Korea, Japan, Taiwan, Colombia, Paraguay and Chile. The most recent addition to the portfolio—the Hong Kong edition, scheduled to take place in the noise sensitive new urban development area of West Kowloon Cultural District’s Nursery Park—was supported by MLA arrays from Martin Audio. The electronic music extravaganza set out to unite fellow… View this post

    studio acoustics
    Peter Janis 09/27/16 06:45 AM,
    This article is provided by Primacoustic   Just like large big commercial studios, smaller and home studios suffer from acoustical interference that can make it more difficult to mix, especially when surrounded with the sound effects and ambiance that now typifies today’s stereo and 5.1 surround sound mixes. In professional studios, the walls are strategically treated with fabric-covered absorptive panels on the sides, front, rear and sometimes on the ceilings. The key to improving intelligibility (or our ability to discern… View this post
