      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

    Auralex Acoustics is now shipping the GeoFusor, a versatile sound diffusor based on the geodesic dome pattern. The GeoFusor’s dimensional shape offers smooth, even diffusion and allows back filling with absorptive material for enhanced low-end control. The GeoFusor is wall- and ceiling-mountable and is offered in two sizes (12 x 12 and 24 x 24-inches). The 24 x 24-inch GeoFusor is sized to fit in ceiling grids and offered in fire-rated and non fire-rated variations. The GeoFusor’s contemporary aesthetic complements… View this story

    Courtesy of Acoustic Geometry.   Once upon a time, back in the big-dang vinyl-record-label era, I was one of two mixing engineers on a big-dang album project with a huge-dang artist. We had the luxury of working in a recording studio with a vinyl-disc-cutting mastering room down the hallway, so, naturally, we took advantage by having reference discs – “refs” – cut just for us. We then schlepped these one-off 33-1/3 RPM acetate LPs around to different homes and stereo… View this story

    Auralex Acoustics is now shipping the new Studio6 Bass Trap.  Low-frequency sound waves are extremely long and they are the toughest to control. This is true no matter whether you’re attempting to block their transmission to a neighboring space or trying to absorb them to clean up the low frequency response within a room. Controlling low frequency sound is harder than controlling mid- or high-frequency sound and generally requires more effort and expense.  In order to address these concerns, Auralex… View this story
