    array prediction
    Bruce Main 04/11/12 04:47 PM,
    Back in the good old days predicting the performance of a group of loudspeakers was a hit and miss proposition. We tried to hit all the people and miss the walls. We were happy if we had enough devices to point a transducer everywhere that needed coverage and enough power to make it good and loud. Complex interactions between devices operating in the same bandwidth, fine level adjustments for individual devices and precise flying angles were the least of our… View this post

    Previously (here and here), we’ve been looking at sound on a “microscopic” level, examining particle motion as sound propagates through air. This time, let’s look at a larger picture of sound wave propagation. A vibrating object will disturb the surrounding air medium causing localized changes in pressure and particle displacement with the transference of acoustical energy in the form of a sound wave. Waves can be broadly classified as being either transverse or longitudinal. The distinction for each wave type… View this post

    A new software and firmware update is now available for the KRK Systems ERGO audio recording interface and room correction system designed to measure and analyze phase and frequency problems within a listening environment. To correct room issues, the internal digital signal processor analyzes and corrects room problems, improving the response at the listening position which results in mixes which translate far better to other playback systems. This latest version includes support for Apple Mac OSX Lion 10.7.3 and Microsoft… View this post

    An understanding of the sound reinforcement system optimization process as described in my previous article (here) leads to what may be a startling conclusion: with relatively little effort, this technology could be leveraged immediately. A number of products are currently on the market that begin to leverage this technology. These range from stand-alone beam-steering column loudspeakers from companies such as Renkus-Heinz, Tannoy and EAW to higher-power arrayable products such as Martin Audio MLA, Duran Audio Target, and Renkuz-Heinz IC Squared.… View this post

    balloon data
    Pat Brown 04/06/12 12:22 PM,
    Two-dimensional graphs are useful for displaying sound system component specifications, but a third dimension is required for considering parameters that are a function of (depend on) a position in space. This includes two data types that are absolutely essential to the sound system designer - loudspeaker directivity data and computer models of auditoriums. Let’s investigate the use of three-dimensional graphs for describing the radiation from loudspeakers. Why is this data needed? Sound radiation is a three-dimensional disturbance that (in most… View this post

    loudspeaker wire
    John Roberts 04/05/12 01:46 PM,
    Too many good folks have been separated from their hard earned money by hyperbolic claims about loudspeaker wire. There will always be people with more dollars than sense, but they don’t last very long in professional audio. I speculate there aren’t many (if any) of you who would pay thousands, or even tens of dollars per foot for speaker wire. A very basic practice in merchandising is called differentiation. Marketers must come up with reasons for why you should buy… View this post

    Rational Acoustics Smaart v.7 measurement data is now integrated in the new Apex Intelli-Ware software control platform for the Intelli-X2 and the Intelli-Z² system management processors. Intelli-Ware 1.4 offers integration of Smaart v.7 data via the Smaart v.7 API (application program interface) enabling transfer of measurement data from Smaart 7 to Intelli-Ware. Smaart’s transfer function and/or spectrum analyzer response can be seen as an underlay in all parametric EQ bode-plot and crossover windows. Virtually all of Smaart’s measurement control features… View this post

    church sound
    Gary Zandstra 03/30/12 08:05 AM,
    This past weekend I was at a Regency Ball with my family for an afternoon of exquisite ballroom dancing (think Jane Austen, 1812). The ballroom is located in South Bend, IN, in a restored old building called the Palais Royale. With its tall ornate ceiling and beautiful wooden floor, it’s one stunning place!  At the ball, there was live music (piano, harp, and flute) and a “caller” who walked us through the dances. He used a handheld wireless microphone feeding… View this post

    Brian English 03/29/12 12:48 PM,
    Many regional sound companies today have made the strategic decision to invest in smaller mid-size line arrays as their main speaker systems of choice (the “A” rig), as oppose to making the huge investment of owning a large-scale “big box” line array system.  One of the reasons for this is a smaller box system is much easier to “scale up” for larger events, than it is for a large box system to “scale down” for smaller events.  And we all… View this post
