Great-sounding albums are becoming increasingly rare, so when I find noteworthy efforts I'm happy to share the news. The goal is highlighting new stuff -- or at least newly recorded/remastered music, and this time I'm going to make separate digital and analog lists. This one covers digital standouts on CD and SACD; next weekend I'll cover LPs.

The list is based on music that I played at home, so I'm sure I've missed some great albums. Share your finds in the comments section.

If you've never heard of the Chladni plate experiment, the principle is very simple. Sound frequencies create patterns. If you can make a metal at certain frequencies, acoustic resonance will cause those plates to vibrate with those patterns.

Normally, you can't actually see this -- unless you sprinkle something granular over the top. Which is exactly what YouTube user Brusspup has done in his latest video. Using a metal plate attached to a speaker, he drove frequencies through it using a tone generator to create intricate configurations of sand. … Read more

There's a new portable Bluetooth speaker in town -- and it's got the Jawbone Jambox and its wireless brethren squarely in its sights.

Bose today introduced the SoundLink Mini, a $200 wireless speaker that's considerably smaller and less expensive than the company's earlier Bluetooth offering, the SoundLink Bluetooth Mobile Speaker II. That model retails for $300 to $350, depending on whether you opt for a nylon or leather cover flap.

The svelte speaker is 2x7.1x2.3 inches, and it's a looker. The frame is a unibody aluminum enclosure that surrounds tiny stereo drivers at … Read more

Sharp makes some of the biggest TVs in the world, so it's not surprising that the company is applying its plus-size worldview to sound bars.

The Sharp HT-SB60 ($320 street) is a startlingly long sound bar, designed to pair up with TVs 60 inches and up. That length may give it a more balanced look under your own personal Jumbotron, but it also allows the HT-SB60 to produce some fantastic sound quality, surpassing that of smaller sound bars in the same price range. There's also enough space on the back for two HDMI inputs, giving you more flexibility … Read more

NICASIO, Calif. -- Growing up in the 1960s, Ben Burtt was such a big "Star Trek" fan that when he went off to college at a school where he had no TV, he had his father record the audio from each week's episode and mail it to him.

Sitting in his dorm room, Burtt would listen to the shows with headphones on, taking in each new episode with no pictures. But he didn't need the video to understand what was going on. "It was so vividly portrayed with excellent sound effects," Burtt said, "… Read more

Bird Sounds Free allows users to learn more about the birds they are looking for, at least sonically-speaking. It's easy to use and provides crystal-clear bird calls.

Bird Songs Free is a fairly basic app, providing a very basic interface and limited features beyond the basic functionality promised in the title. It opens with a grid of bird pictures. None of the birds is labeled, so unless you know your way around a chart of bird pictures, you'll be largely tapping at random. There is no way to know the accuracy of the bird calls in the chart … Read more

No one can deny the popularity of sound bar speakers, but I've always been frustrated by their sound quality. There were exceptions; the $899 Atlantic Technology PB-235 and $699 SpeakerCraft CS3 are quite good, but in the more popular $300-to-$400 range the 'bars weren't all that great. Granted, they were a big step up from TV speakers, but their sound was still a compromise, compared with what's available from the better $300-to-$400 Emotiva and Audioengine self-powered stereo speakers (they get hooked up from your TV's stereo analog jacks).

A few weeks ago I spent … Read more

Nearly every sound bar claims it can create faux surround sound without extra speakers, and with a few exceptions, those claims are always overhyped.

The Vizio S4251w-B4 ($330 list) is one of the very few sound bar systems on the market that can deliver true surround sound, precisely because it augments the traditional sound bar/subwoofer configuration with two rear speakers. The combination delivers some of the best sound we've heard from a budget sound bar, and nothing at this price competes in terms of immersive home theater sound. The rest of the package is polished, too, with a … Read more
