Two days before the main show floor opens, and a day before the round of press conferences from major players in the consumer electronics industry, on Sunday evening the CES Unveiled event crowds bleary, travel-worn, journalists into a giant ball room to give them their first taste of what the rest of the week will have to offer.

Events like CES Unveiled (two more product zoos will take place on Monday and Tuesday nights) are an unreliable barometer for big news—very significant product launches usually get their own event—but sometimes there can be breakout hits that define a category, like Parrot’s original AR drone a few year’s back, or Lego’s Mindstorms EV3 last year.  And even though I didn’t spot a product Sunday that seemed to have the potential for such influence, CES Unveiled is still a good sampling of the general zeitgeist.

In recent years, for example, mobile apps had been two-a-penny, while now mobile-enabled hardware is very much to the fore, especially in the areas of digital health, home automation, and entertainment robotics. Interesting new technologies were also on display, like Novasentis’ haptics sensors and actuators (we expect to have more on Novasentis later this week.) And 3D printing is making a play for the bigger time.

And, psychologically speaking, after several years in which exhibitors maintained determinedly, sometimes aggressively, cheery attitudes in the face of a challenging economic environment, people seemed a little more relaxed this year—although that may change as results from the 2013 holiday shopping season are analyzed and digested for winners and losers.

The century-old quest for truly realistic sound production is finally paying off

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
