    Trap boxes and line arrays get all the attention. And that’s no surprise – they’re big and loud, and dare I say it, glamorous. But the truck rarely rolls without a complement of two-way loudspeakers sporting a 12-inch or 15-inch woofer and a horn. Whether its monitor wedges, drum fill, front fill or just “speakers on sticks,” small 2-way boxes do many of the everyday jobs that make up a typical sound reinforcement day. We take the performance of these… View this story

    Audio Precision announces the introduction of the APx1701 Transducer Test Interface. The system integrates instrument-grade amplifiers and microphone power supplies for designers and production test engineers seeking clear insight into the behavior of their electro-acoustic devices. With a signal-to-noise ratio of 134 dB, the APx1701 provides 20 dB of fixed-gain amplification from DC to 100 kHz. In the frequency range of 10 Hz to 20 kHz, the APx1701’s residual THD+N is ≤ -106 dB (80 kHz BW), and frequency response… View this story

    This article is provided by Rane Corporation.   Editor’s Note: This article was originally published through The Rane Library in 2005, yet the information is as relevant now as it was then. Acoustic feedback (also referred to as the Larsen effect) has been roaming around sound reinforcement systems for a very long time, and everyone seems to have their own way to tame the feedback lion. Digital signal processing opened up the microphone to some creative solutions, each with its… View this story

    This article is provided by PreSonus.   In May 2014, the VU meter celebrated its 75th birthday. It has served the industry well, and when properly interpreted, it’s still useful. However, today’s digital recording processes have caused us to take a hard look at the usefulness and inadequacy of both the traditional VU meter and its modern replacement, the LED level meter, as tools for signal-level management. The classic VU meter, though relatively rare today (primarily because of cost), has… View this story

    This article is provided by EarLevel Engineering.   Some terms: The Fast Fourier Transform is an algorithm optimization of the DFT—Discrete Fourier Transform. The “discrete” part just means that it’s an adaptation of the Fourier Transform, a continuous process for the analog world, to make it suitable for the sampled digital world. Most of the discussion here addresses the Fourier Transform and its adaptation to the DFT. When it’s time for you to implement the transform in a program, you’ll… View this story

    Courtesy of Acoustic Geometry.   It’s a truism in standards-testing industries: you can only test for parameters for which you have tests. In the acoustics business that means testing is limited to measurement values which have accurate and repeatable tests, like sound pressure. This is especially important when you consider that hearing – our system of ears and brain – is highly complex, and some sound-perception functions have no equivalent in current test methodologies. Or, put more simply, you can’t… View this story

    Audio Precision announces its planned application demonstrations for ProLight + Sound from April 5-8 in Frankfurt am Main, Germany. Attendees seeking to understand and solve measurement challenges should visit AP in Hall 4.1, Stand A20 for hands-on demonstrations of audio and electro-acoustic testing, and the accompanying expertise of AP’s technical staff. Enhanced Electro-Acoustic and Production Testing Audio and electro-acoustic test within a manufacturing environment can present unique challenges for the test engineer. Audio Precision’s latest software release, v4.2, adds a… View this story

    Pat Brown 03/04/16 06:44 AM,
      The procedure often followed for equalizing a loudspeaker is to place the measurement microphone on-axis and adjust for the flattest frequency response. This often involves boosting some filters when the axial response over a range of frequencies is lower than the average. Those that are opposed to the use of boost filters may choose to arrive at the same resultant response by reducing (cutting) parts of the response to the lowest common denominator. This results in the same electrical… View this story
