There’s much to love about YouTube (Rick Beato, Rahsaan Roland Kirk playing “I Say a Little Prayer”), but it’s coming at a price: the dumbing down of the audio industry. I got some inkling of this future in 1990, the first year of my audio career, when an acquaintance asked me, “How are those Bose speakers? I heard them on a TV commercial, and they sounded pretty good.” He was in the oil biz, not the audio biz, so I didn’t blame him for failing to grasp that he was hearing not a Bose system, but recorded music played through his TV speakers. Yet thanks to the Internet’s negligible barriers to entry, people who claim to be audio experts are now making the same mistake he did.
Every time I talk with my friend John Kellogg, I learn something new. John’s the vice president of Advanced Strategic Solutions for Xperi, parent company of DTS. That basically means he’s a liaison between Xperi and the music and movie production communities, a position he previously held for Dolby. John spends a lot of time in recording studios, and has a very good one of his own, too, so he’s always up on the latest trends in pro audio. Thus, when he recently told me, “Oh, the loudness war’s over; it’s all LUFS now,” I had yet another of the “Wait . . . what?” moments common to our conversations.
You can say one thing for sure about 2020: there was probably never another year in which headphones were more important—whether they were being used for monitoring Zoom meetings, letting the kids watch their online classes without driving you crazy, or blocking out the noise when the lessons were done and the kids were driving you crazy. Just as important was our headphones’ ability to bring us music and movies that soothed our souls while not distracting other members of the household.
We seem to be experiencing a minor revolution in audio product testing. For the last two decades, audio product testing has been almost entirely subjective, rarely based on anything more than the opinion of a single listener, formed in uncontrolled, sighted tests. Until recently, SoundStage! was one of only a few audio publishing outlets presenting controlled, objective testing—specifically, audio measurements. But recently, measurements have become more common on websites, online forums, and YouTube. As someone who, since the late 1990s, has been nagging for more audio measurements in reviews, I should be happy about this—and I am, but it has me concerned, too.
Two recent experiences have reminded me of an old and very important lesson about audio I and many thousands of other audio enthusiasts learned decades ago. But the lesson seems mostly forgotten. The first experience was a couple of “run-ins” with other audio writers -- one directly, on Facebook, and the other indirectly, through an editor friend of mine. The second was recording and mixing I’ve done for what will soon be my first jazz album: a collaboration with saxophonist Ron Cyger under the name Take 2.
With a few rare outliers excepted, there are two different types of earphone drivers: dynamic drivers and balanced armatures. Although great earphones have been made with either type of driver, and often contain both types, the two drivers are very different in form and performance. Most headphone enthusiasts understand the concept of dynamic drivers, which are basically just miniaturized versions of conventional speakers, but many do not understand how balanced armatures work, or what their advantages and disadvantages are.
