Charlie Hughes 05/16/13 05:56 PM,I’ve heard it argued by that square waves contain DC. How else could they have the flat top and bottom that make it square? Let’s look at a square wave and see what causes it to have its square shape. A complex waveform can be constructed from, or decomposed into, sine (and cosine) waves of various amplitude and phase relationships. This is the basis of Fourier analysis. A square wave consists of a fundamental sine wave (of the same frequency… View this story

Pat Brown 05/14/13 04:06 PM,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 curve,… View this story

Jon Tidey 05/10/13 02:25 PM,This article is provided by Audio Geek Zine. I recently saw this on a forum. I’ve seen something like this said many times. I won’t say who said it because he’s a good engineer and my intention is not to poke at him. Here goes: “I’ve been sticking with 88.2, to me the simple math (divide by 2) is a little more reassuring then 96 when down-sampling to 44.1.” ***facepalm*** Another guy (elsewhere) said: “If you’re recording music, you… View this story

Joe Gilder 05/09/13 02:33 PM,These videos are provided by Home Studio Corner. Some guitarists understand the ways that delay can be used to change and enhance the sound of a passage/part. In this video, Joe reveals the technique and the reasons why it works, and then shows how to apply it via several passages of a track he’s working on for his upcoming album. It’s quite interesting to listen to the differences it can make, and at times it effectively transforms a mundane… View this story

PSW Staff 05/03/13 10:37 AM,Xilica Audio Design and Audinate have announced the launch of Xilica’s new Dante-enabled Neutrino and Uno Series digital processor models. Neutrino is an open architecture-drag and drop based DSP while Uno is a hybrid architecture/apps based DSP. Neutrino and Uno digital processors are available in 8x8, 8x16, 16x8 and 16x16 I/O models. Dante enabled models provide an additional 32 channels (16x16) of I/O via Audinate’s Dante network solution. Note that Neutrino and Uno Series Dante-enabled models not available in North… View this story

Joe Gilder 05/02/13 12:59 PM,These videos are provided by Home Studio Corner. In the first of two videos, Joe builds on a commonly used technique, showing how utilizing delay to more tightly align signals can in turn pay huge dividends in bass tone. And in the second video, he addresses a query from an audience member, demonstrating the suggested approach and then contrasting it with his own way of going about it. Both solutions end up working quite well, providing additional “tools in the… View this story

PSW Staff 04/24/13 06:23 PM,Radial Engineering has announced a new addition to the 500 series range of modules, the PreComp combination preamp and compressor. The design begins with a high-performance preamp equipped with Radial’s unique Accustate gain control that simultaneously sets the output and sensitivity to maximize signal-to-noise at all levels. This is particularly important when recording in the digital domain where background noise can often be audible during quiet passages. A full-feature compressor follows with adjustable threshold, compression ratio and make-up gain control… View this story

John Lenard Burnett 04/23/13 05:33 PM,This article is provided by Lenard Audio. Three octaves or 3.2 octaves (1 decade) is the optimum bandwidth for a loudspeaker (a topic which we’ll touch on later). The crossovers function is to decrease power at a given rate from either or both sides of a given bandwidth. The slopes rotate phase in opposite directions. In some passive crossovers this is adjusted for by reversing the polarity of adjacent loudspeakers. Electronic active crossovers can have extra compensating circuitry. Crossover… View this story
