High dynamic range is still the hot tamale in today's video world. While it's been around for a few years now, nothing new in video has yet made HDR yesterday's news. Here’s why.

The 1972 movie version of the Broadway musical 1776 has been available on Blu-ray for some time, but it was only recently released on a multidisc package headlined by an 4K Ultra HD transfer. And it's certainly an appropriate month to have a look at it. 1776 began as a hit Broadway musical in 1969, winning several Tony awards (including best musical) and ran for three years. It hit the big screen in 1972...

Spring is traditionally prime time for the audio industry to dust off the cobwebs and bring out their best and latest gear at a hi-fi show for the public to see, hear, and touch. But the pandemic of the past two years wreaked havoc on the show front.

Audiophiles have an inherent advantage over home theater enthusiasts: when it comes to setting up their systems, they need only make room for two loudspeakers plus a convenient location for the sources and amplifiers needed to drive them. For a home theater we need to find space for more, often much more. Those multiple speakers must also support the screen, and often there isn't much flexibility in where to put the latter—be it a TV or a projector with a separate screen. In any home theater setup the locations for the center, surrounds, and perhaps overhead speakers are then usually fixed by the placement of those front speakers and the main listener/viewer positions, with little room for deviations in a proper setup.

But positioning one or more subwoofers for the best results is a chore that takes time and patience. Subwoofers are relatively rare in 2-channel systems, which is unfortunate because they can achieve soul-satisfying bass while limiting the need for hulking, and expensive, front left and right loudspeakers.

When I wrote about the new film version of Dune some months back my reaction was positive. I saw it in a movie theater—my first visit to one in two years. There was plenty of social distancing during my visit; with a dozen or so other attendees at a midweek, midafternoon showing I could have swung a cat on a 10 foot rope without hitting anyone (with apologies to cat people). I enjoyed the film, but as I noted in that October 2021 blog, I was disappointed by the quality of much of the cinematography. This was surprising, since it was the Dolby Cinema in my local AMC-plex. Dolby Cinema is by far my favorite way to see a movie in a commercial theater. It wasn't the sort of disappointment the average viewer would feel, and even I could set my concerns aside once I got into the film. But I know Dolby Cinema can do better and the film deserved it.

The human visual system is a lot more complicated than we might imagine. A recent paper published in the journal Science Advances (January 12, 2022), Illusion of visual stability through active perceptual serial dependence, by researchers Mauro Manassi (University of Aberdeen, UK) and David Whitney (UC Berkeley), takes this idea a step further. I can't pretend to have slogged through the bulk of this article. The text is dense with the sort of science-speak common to experts in their field of expertise but nearly incomprehensible to the layman (a worldwide issue over the past two years, but I digress!)
