Ethan Winer 05/11/12 11:11 AM,Jonathan: “You lied first.” Jack: “No, you lied to me first.” Jonathan: “Yes, I lied to you first, but you had no knowledge I was lying. So as far as you knew, you lied to me first.” — Bounty hunter Jack Walsh (Robert De Niro) arguing with white-collar criminal Jonathan Mardukas (Charles Grodin) in the movie Midnight Run When it comes to audio fidelity, the four standard parameter categories can assess any type of audio gear. Although published product specs… View this story

Sam Berkow 05/08/12 05:35 PM,If one could listen to only the direct sound of a loudspeaker, the world would be a very different place! Unfortunately, free field listening, where you have no reflections, room modes or ambient noise, is hard to achieve in everyday life, so we listen to loudspeakers in real rooms. The interaction of a loudspeaker system and a room can be very complex to understand, model or measure! One way to measure this interaction is to measure the impulse response of… View this story

PSW Staff 04/30/12 04:46 PM,AFMG, the Germany-based pro-audio software developer, is releasing the new version of SysTune – Version 1.2—on Tuesday, May 1. The update is free for the community of existing SysTune users. SysTunev1.2 is highlighted by a new plug-in called Delay Analysis. From a set of captured individual measurements, SysTune automatically calculates optimal delay times between mains and subs or between main and delay loudspeakers, giving precise information on polarity and predicted overall system performance. “Never before has it been easier to… View this story

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 story

Pat Brown 03/07/12 03:35 PM,One of my favorite field tools is a basic analog impedance meter. It can be used to troubleshoot a host of sound system problems, either stand-alone or with some additional gadgets. The TOA ZM-104 has been around for many years and many experienced audio people have one. Mine has served me well and has the scars to prove it. It will be the example meter used in this article, although in principle the tests can be conducted using any similar… View this story

Gerry Tschetter 03/06/12 02:15 PM,The terms +/-3 dB and -6 dB are frequently (and erroneously) used interchangeably to characterize the frequency response of a loudspeaker system. This has led to understandable confusion among consumers who may believe that a +/-3 dB specification is more rigorous than a -6 dB specification. The purpose of this document is to explain the meaning of both specifications as they are commonly used (or misused) in pro audio today, and to provide a basis for comparing loudspeakers with differing… View this story

Pat Brown 02/20/12 02:03 PM,If acoustic parameters sometimes seem difficult to grasp, this practical example should help clarify at least one of them, the Limiting Distance, DL. This is a parameter associated with reverberant spaces, such as gyms and churches with little absorption. Remember that in such spaces there will exist a reverberant sound field LR, that is uniform throughout the space, as well as specific reflections that are not. If a loudspeaker or other acoustic source is used to excite the space, there… View this story
