    This article is provided by Home Studio Corner.   You hear it all over the place. “Help! My mixes don’t translate!” In other words, “My mix sounds awesome in my studio, but then when I play it anywhere else – in my car, on my stereo, on my iPod – it sounds awful.” What’s the problem? It could be any number of things – your monitors, your room, your headphones…maybe even your recordings themselves. But let’s step away from talking… View this post

    Go here to read part 1 of this series.————————————————— “In the beginning there was graphic EQ.” The first standard tool for system equalization was the graphic equalizer. Early versions were 10 bands at octave intervals, but the 1/3rd-octave version took over the market completely by the late 1970s. The 31 bands were standardized to a series of 1/3rd-octave intervals beginning with 31 Hz. There was no standardization of the shape of the filters, however. One model might use 1/3 octave… View this post

    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 post

    Provided by Live Sound Advice.   If terms such as gain structure, impedance matching and headroom are unfamiliar, or worse, give you a headache, don’t worry, you’re not alone. Most church sound techs would rather have their gear work perfectly right out of the box than have to tweak it into compliance. Nevertheless, when it comes to setting up and operating a sound system, a working knowledge of gain structure (and a few related concepts) will help you get the… View this post

    Music streaming is officially going high resolution. The industry’s official logo mark for Hi-Res MUSIC – previously applicable primarily to high-quality digital download services – will soon be available for adoption by music streaming services as well, according to an announcement today from the Recording Industry Association of America (RIAA) and its member companies Universal Music Group, Sony Music Entertainment, and Warner Music Group, in cooperation with the Recording Academy Producers & Engineers Wing, the American Association of Independent Music… View this post

    In this article we’ll investigate how the speed of sound in air is, for all intents and purposes, exclusively temperature dependent within the audible bandwidth of our typical applications. There are some popular misconceptions on this subject related to pressure, density, and other effects that are addressed here. The speed of sound is the distance traveled per second through an elastic medium. The medium is composed of molecules held together by intermolecular forces. Sound energy passes through the medium by… View this post

      Crossover networks are not unique to audio and acoustics. The role of such a network is to produce a transition between two systems of differing capabilities. In a loudspeaker system, an increased overall bandwidth is achieved by splicing together two or more lower bandwidth transducer responses. An individual woofer, squawker and tweeter can form a full-range system through the use of a crossover network. Let’s look at some other systems that require similar transitions between their individual components. Several… View this post

    Many studios built in the 1970’s were designed not to have any acoustic influence on the recorded sound produced in them. This was accomplished by over-deadening walls, floors and ceilings so no sound waves (leakage) would reflect and add (or subtract) from the instrument’s original sound waves. Bass traps were purpose-built for controlling sound from electric bass amps, small isolated (and dead sounding) drum booths were mandatory and heavy gobos or baffles were used around all musicians separating them and… View this post

    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 post

    Craig Leerman 05/02/16 02:05 PM,
    As an audio technician, my ears have the final say in how a system is tuned, but with the passing of time, they’re not quite as reliable as they used to be. As a result, I’m increasingly relying on measurement systems to help with dialing in the PA. I also utilize SPL apps on my phone and iPad to help monitor volume levels, and that’s worked out well. So when I first saw the iSEMic 725TR measurement microphone from iSEMcon,… View this post
