    This article is provided by   I have a curmudgeonly hate for modern technology. I like roll-up windows and faucet handles and telling stupid electronics what to do, when, and at what volume. I avoid the automated doors at stores in favor of the pull-handle ones. I think there’s something to human beings, to humans BEING, that technology at its zenith can’t beat. In the world of life, this makes me a dinosaur. In the world of audio, it… View this post

    DirectOut introduces MADI.MONI, an ergonomic MADI tester and mobile MADI monitoring tool. MADI.MONI has been specifically designed with a small footprint for MADI testing and monitoring in the field. MADI.MONI offers a simple, uncluttered interface enabling users to see at a glance all format parameters as well as the signal quality of a MADI stream. Operation is straightforward via four push buttons on the UI including a volume/channel selection to monitor individual channels of a MADI signal via the 3.5mm… View this post

    Audio Precision announces the introduction of their Speech Transmission Index (STI) plug-in for APx500 audio test software. Created for engineers developing public safety (police, fire, emergency) communications and public address systems, as well as flight recorder devices, the APx STI plug-in provides measurement capabilities conforming to international standard IEC 60268-16 (2011). Developed as a method for quantifying the intelligibility of speech with respect to a transmission medium—for example a room, an intercom system, a radio link—STI is an objective measure… View this post

      One of the most confusing subjects in audio? Loudspeaker power ratings. It’s generally accepted that a large loudspeaker power rating is a sign of quality and something to be desired. And it’s the performance metric that probably has the greatest influence on the consumer’s buying decision. But a closer look reveals that power rating is far less significant than other metrics regarding the performance of the loudspeaker. The term “power rating” requires further explanation to avoid misunderstanding. It’s tempting… View this post

      When most people think of sound reinforcement systems, or audio systems in general, they rarely do so with regard to speech intelligibility (SI). It’s usually about the music, with the assumption that if a system sounds good for music, it should work for speech. While this can be true in small, well-behaved rooms, it is seldom true in large spaces. My first sound system disaster was the design and installation of a large, expensive sound system that failed to… View this post

    From the March/April 1977 issue of the late, great Recording Engineer/Producer (RE/P) magazine, the principals of Abadon/Sun Studio, which was located in San Antonio, TX, look at the practical and technical sides of studio design. We at Abadon/Sun decided to write this article because we felt a large number of small studio owners required more information to properly design and build their first studio. What we’ve tried to do is to simplify things as much as possible and provide the… View this post

    As audio engineers, we’re constantly presented with choices that involve compromise and give and take. Many of these are budgetary and/or based on realities of what’s available or possible for a given application. Tradeoff, TANSTAAFL and triage are underlying principles to my decision-making process in the design and optimization of sound systems. The concept of the tradeoff is simple: give up something to get something. TANSTAAFL is an acronym created by sci-fi writer Robert Heinlein: “There ain’t no such thing… View this post
