Monday, April 09, 2012A Road Map Of Future Loudspeaker Optimization
Adam Shulman 04/09/12 02:31 PM,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

Friday, April 06, 2012Graphing In 3-D: Another Parameter To Account For Space
Pat Brown 04/06/12 01:22 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

Thursday, April 05, 2012Science Or Snake Oil? The Facts Behind The Hype About Loudspeaker Wire
John Roberts 04/05/12 02:46 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

Tuesday, April 03, 2012Rational Acoustics Smaart v7 Integreated In New Apex Intelli-Ware Software Control Platform
PSW Staff 04/03/12 01:16 PM,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

Friday, March 30, 2012Understanding Specification Sheets: What Do The Charts & Graphs Really Mean?
Pat Brown 03/30/12 02:47 PM,For the majority of humans, there is nothing simpler than listening to sound. You simply, well, listen. When it becomes necessary to describe the listening experience analytically, however, a host of complex equations and diagrams are required to describe even the simplest of sonic events. The benefit of mathematical analysis is that it can yield insights that are not apparent through intuition alone. Acoustic signals are easily measured, and the audio components that produce them have characteristics that can be… View this post

Church Sound: Acoustics… It’s All About Signal-To-Noise
Gary Zandstra 03/30/12 09:05 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

Thursday, March 29, 2012In Need Of The “Big Hammer”
Brian English 03/29/12 01:48 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

Wednesday, March 21, 2012Recording: The Importance Of Space In A Mix
Matthew Weiss 03/21/12 05:54 PM,This article is provided by the Pro Audio Files. We spend a great deal of time considering individual sounds in a space. We prescribe attributes to the instruments and the players in order to organize our thoughts about the sounds and how they blend. We may often say a singer is “mid-rangy,” a snare is “ringy,” or perhaps the acoustic guitar is “warm.” We do the same for microphones, pre-amps, compressors, and what have you. It is surprising how… View this post

Saturday, March 17, 2012Loudspeaker Arrays: Ideas, Data & Solutions In Solving Horizontal Coverage Problems
Pat Brown 03/17/12 02:27 PM,A loudspeaker array is a collection of loudspeakers that is assembled to achieve a coverage pattern that cannot be achieved with a single device. Arrays are most commonly implemented to achieve a wide horizontal coverage pattern from a position on or above the stage. The “perfect” array would be a collection of loudspeakers whose radiation pattern was indistinguishable from a single (hypothetical) device that provided the needed pattern for the audience area. Many attempts have been made to solve the… View this post
