With all due respects to all the great analog engineers out there, it is my opinion that anything an analog circuit can do, software can do better. You don't agree? Fight me. Case in point: software-defined radio.

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.

Ken C. Pohlmann  |  Nov 28, 2017  |  1 comments
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....

Walk down any city street and you'll see nearly everyone sprouting earbuds and singing along to music heard only by themselves. Call me old-fashioned, but that bugs me.

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.
