    Ray Luzier moved to the Nashville area over two years ago to take part in its music scene, a way to keep his career as the drummer for Korn (as well as other artists including David Lee Roth, Metal Shop [now known as Steel Panther] and KXM) in high gear and let his family enjoy the culture – a change from Los Angeles, to be sure. One of the first things he did in his new home was convert several… View this story

    Very often the topic of “room tuning” comes up in the practice of pro audio, but what we’re really talking about is “system optimization.” And over the course of many years, we’ve used many tools that seemed to—or actually did—contribute to desirable results. But system optimization is not just about turning knobs (virtual or otherwise) until things sound good. Sure, you can do that, and maybe that’s all you have time for under certain circumstances, but it’s not likely to… View this story

    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 story

    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 story

      The human auditory system is equipped with two inputs - left and right ears. This “binaural” processing system provides us with the ability to localize where sound is coming from, something that a one-eared listener would have difficulty in doing. Playback systems may utilize any number of channels to surround the listener with sound, but two channels is always enough to simulate the human listener. Recording enthusiasts have long discovered the benefits of stereo microphones. While not necessarily “human-like,”… View this story

    It was 1984 when I first sat in front of an FFT (Fast Fourier transform) analyzer during a concert and made decisions about tuning sound systems. I’ve been doing it ever since, and have written a lot of articles and a few books about this, but these are usually very focused and detailed. This time I’ll go a completely different direction: a dartboard of 30 things I’ve learned in 30 years of being hyper-focused on one thing. No proofs or… View this story

    Auralex Acoustics is now shipping its updated MudGuard v2 microphone shield, which isolates mics by helping to eliminate external noise bleed and filtering out external overtones. The design utilizes Auralex Studiofoam to reduce excessive room ambience and off-axis sound. It offers a unique, patent-pending multi-radii convex shape designed to direct unwanted and off-axis acoustic energy away from the mic. In addition, the non-perforated, solid back on the MudGuard v2 provides additional isolation by blocking sound from the recording environment, through… View this story

    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

    GIK Acoustics has announced the debut of a new sound booth: the PIB (Portable Isolation Booth). The PIB is made of 2-inch thick rigid fiberglass which effectively absorbs down to 150Hz, with large surfaces to catch and absorb more room reflections. The large size also means the PIB surrounds the mic making it more natural for a singer as opposed to singing into a U shaped piece of foam. Unfolded it acts as a vocal booth; and unlike a mic… View this story
