All we hear is radio ga ga.

Audiophoolery: Pseudoscience in Consumer Audio. You might think that a science-based field like audio engineering would be immune to the kind of magical thinking we see in other fields. Unfortunately, you would be wrong [...] As a consumerist, it galls me to see people pay thousands of dollars for fancy-looking wire that’s no better than the heavy lamp cord they can buy at any hardware store. Or magic isolation pads and little discs made from exotic hardwood that purport to “improve clarity and reduce listening fatigue,” among other surprising claims. The number of scams based on ignorance of basic audio science grows every day. Via.

(NSC) - RIP Ron Murphy, master vinyl cutter.

Ron Murphy cut records, but not just any records. Responsible for cutting the actual vinyl master plates of much of the now revered Detroit Techno including Jeff Mills, Carl Craig, Underground Resistance's seminal Knights of the Jaguar, and much more - he demonstrated impeccable craftsmanship and skill in both mastering records for sound and aesthetics at company known as Sound Enterprises source link AKA National Sound Corporation. Schooled in Motown, dubplates and jukeboxes, he is the bespoke-crafted, analog link between the digital future and analog past that is the roots of Techno music and modern techno DJ culture.

Mayan sound engineers

Were the Mayans expert sound engineers? Perhaps we could learn something from them to aid our pursuit of technological solutions to modern noise pollution problems.

There's been a lot of talk of late about signal-to-noise ratios here on MeFi (er, Ashcroft who?...). Generally, we think of noise as something that always degrades the quality of a signal. Sometimes, however, the opposite can be the case. Here's a neat little demonstration of a non-linear system in which noise can be used to amplify a signal that would otherwise be too be faint to detect any other way. It exploits a phenomenon known as Stochastic Resonance.
