Surround Sound Technology Training Tony Weber BG Radia Corporation

Apr 2010

 Starting with Dolby Surround, which used four channels (front left, front right, phantom center, mono surround – though usually using two speakers), the public began to expect the increased realism brought about by sound location cues being able to move across the front soundstage, and from front to rear for ambience or special effects.
Audio, Distortion and Feedback Nelson Pass Pass Laboratories

Jan 2009

 Feedback is very large subject, and I am going to limit myself to some simple tutorial comments and a discussion of phenomena associated with complexity in distortion created by nonlinear gain stages, negative feedback, and the audio signal. Taken singly, these phenomena seem simple enough, but when they interact, they create distortions out of proportion to what you expect from the specifications found in product brochures. There are linear and non-linear forms of distortion. Linear distortions affect the amplitude and phase of audio signals, but don't show up on harmonic distortion analyzers as added frequency components that weren't there in the first place. Tone controls are a good example of circuits with linear distortion. Nonlinear distortions are those which add new frequency components to the original signal, either as harmonic multiples of the original frequencies or as sidebands resulting from their non-linear interaction between the original frequencies. Nonlinearities are often deliberately created in musical instruments themselves, but they are unwanted in music reproduction. We will be talking about nonlinear distortions.

Even The Best Isn't Perfect Gary Dayton THIEL Loudspeakers

Nov 2008

 Regardless of the fact that you spent a minor (or major) fortune on your home stereo or theater system, it still is possible that a breakdown can happen. Since loudspeakers always manifest the problem regardless of where it actually occurs, many are quick to blame them. Sometimes folks are right - the loudspeaker failed. But often there is a failure elsewhere in the system that is merely being passed on to the speakers.

Sep 2008

 Yet another advanced compact disc recording format which made a valiant attempt at deposing both conventionally recorded compact discs as well as Sony’s SACDs was the format, xrcd. Although SACD seems to have a slight edge on xrcd, this relatively obscure format continues to sell.

Slink-e & CDJ Brooks Talley InfoWorld

Oct 1998

 Initial setup of CDJ is a piece of cake; I simply plugged it in, and told CDJ to go index my collection. Out of 280 CD's, CDJ correctly identified 274, mis-identified two, and couldn't identify 4 because they weren't in the CDDB database.
