As the AES3 digital audio standard allows for word lengths up to 24-bits as well as a variety of sampling rates, SMPTE 272M provides the means for embedding these signals.

Fingerprinting or correlation techniques involve comparing two signals, a reference source known to have no lip-sync error, and a second signal somewhere down the signal chain.

Are audio consoles obsolete in the age of digital audio workstations and computer audio editing programs? Not by a long shot.

The CALM Act is a reality.

But how meaningful are these specs? Do they provide the information we need to differentiate performance among competing models?

Sound has dimension, and it's sometimes easy to forget just how big sound can be.

Many processors, such as embedders or encoders, have internal delays, obviating the need for external ones.

It's truly amazing the extent of available measurement tools that literally fit in the palm of a hand.

At its core, the standard defines digital phantom power (DPP) for a microphone with built-in digital circuitry.

Audio and video facilities come and go.

How do file-based and real-time loudness processors fit into an overall facility audio system?

For any kind of loudspeaker system to be practical, the drivers need to be mounted in some kind of enclosure.

The AES3 digital audio signal is composed of frames, with each frame containing a digital sample from each of two audio channels.

An Audio By Design reader named "Bro Duke," writes in about his microphone pet peeve, "their lack of internal filters.

As audio systems designers, we rely on manufacturers' specifications not only for a list of features, but for how a piece of equipment can be integrated into a system.
