How many copies of Jurassic Park do you own? I'll give you an hour to tell me. That's because if you are a dino-fan, it will take awhile to tally them all. Don't miss any! There's VHS, Laserdisk, DVD, the Trilogy DVDs, the Adventure Pack DVDs, Blu-ray…. So, how many copies of Jurassic Park do you own? Well, get ready to buy some more. The Jurassic Park: Ultimate Trilogy Blu-ray set is being released today (with a freshly remastered DTS-HD Master Audio 7.1 soundtrack and a whole lotta extras as incentives to purchase). And after that. . .

I am an audio guy. All my life, I have been fascinated by the physics, physiology, and technology of audio. You might be surprised to know this, but my hearing is more important to me than my eyesight. But hearing is a privilege that not everyone shares.

How important is internet connectivity? In a poll of 18- to 25-year-olds in the U.K., they valued a good internet connection more highly than trifles such as a healthy diet, hot water, daylight, and the welfare system. Now, I admit that vegetables have never been high on my favorites list. Hmm....

If you're like me, you wake up every morning from a wonderful dream where you own a LP replication plant. In your factory, plastic goes in, and plastic goes out. Except that the outgoing plastic has magical shapes pressed into it. Now my dream, and yours, can come true.

You probably saw the news story last week. Unbeknownst to them, a couple's Alexa Echo recorded their conversation, then emailed it to someone in their contact list. Creepy. Here's how you can determine what Alexa has recorded in your house, and edit the archive and delete files.

Black Friday has a lot in common with circumcision. In both cases, they generally occur whether you like it or not. And I am not a fan of things in which I have no say-so. Both of them also inflict sensations ranging from mild discomfort to outright pain. Although, women don't seem to mind it as much as men. One key difference between Black Friday and circumcision is that after Black Friday, at least you have a new TV.

Shakespeare famously observed, “Brevity is the soul of wit.” But if Shakespeare could read modern texts, peppered with AFAIK, IMHO, LOL, OMG, ROTLF and WTF (which is NSFW), I’m not sure he would make the same assertion. And don’t get me started about emoticons.

Saturn's rings are pretty cool. They are clearly visible with even a modest telescope. Going where no spacecraft has ever gone before, the Cassini spacecraft is diving through the rings and into the gap between the rings and the planet's surface. Enterprising scientists at JPL have created a file that lets you hear the "sound" of particles impacting the spacecraft as it passes through the rings and into the gap.

You remember Gravity, right? Outer space, pulverized space ships, Sandra Bullock floating weightlessly, heavy breathing—pretty good film from both a technical and narrative standpoint. You might already have a copy on Blu-ray. But I'd like to give you two reasons to consider buying it again. A new "Diamond Luxe Edition" Blu-ray due in February promises to be very interesting for both film aficionados and home-theater enthusiasts. Doubly interesting if you are both.

How many times has this happened to you? You’re rounding the Warsteiner-Kurve at the Nürburgring at about 3 lateral Gs and your iPad Mini flies out the window of your Porsche 997 GT2 and lands on a hausfrau’s schnitzel, and she exclaims, “Mein Gott in Himmel!”

IRIVER is hopping on the MQA bandwagon, starting with its Activo CT10 streaming player, with other models to join in later. Is this good evidence that MQA is turning the corner to become the defacto standard bearer of hi-res music?

Keeping track of Apple rumors is a full-time job. And I must admit that since I am not an Apple fanboy, I don't really pay close attention. But one persistent rumor is that Apple will soon launch a new headphone — and dare I say it — it may be an audiophile headphone.

Ground control to Major Tom. Ground control to Major Tom. Take your protein pills. And put your helmet on. Your roadster is washed and waxed. Turn your stereo on. That's earth in your rear-view mirror.

Okay. I get it. Contemporary electronic devices are more powerful than old-timey electronic devices. A software engineer recently estimated that a USB-C charger has more computing power than the guidance computer on the Apollo capsules that took men to the moon (shown above). Awesome. But I still have an axe to grind.
