New Microphone Uses Smoke — and Lasers!

Most microphones translate sound waves into electrical signals using vibrating membranes and magnets, capacitors, or other electrical components. But for decades, audio engineers have dreamed of using lasers to detect sound waves instead.

Now, audio engineer David Schwartz has succeeded. His prototype uses a laser, smoke-filled air, and a super-sensitive photocell to pick up the sonic vibrations in the air and translate them into audio signals.

The resulting recording is, well, not even as good as 100-year-old wax cylinder recordings, but Schwartz says he’s not concerned because it’s just the “talking dog” phase of the project.

“We don’t care if the dog is delivering a Shakespeare sonnet — it’s just the fact that the dog’s talking,” Schwartz told Wired.com’s Eliot Van Buskirk.

Check out Wired’s exclusive video with Schwartz, above — and to learn more, read the rest of our report on Wired’s business blog, Epicenter.

Video: Emo Labs’ invisible speakers visibly demonstrated

Emo Labs is out on a crusade to unify audio and video into one cohesive, delectable whole. If you’ll recall, the company’s Edge Motion invisible speaker tech relies on implanting a clear membrane atop display panels, which is then vibrated by piezoelectric actuators to generate stereo audio. We’ve grabbed a couple of vids of it in action to whet your appetite, and while there’s still no word on when, plans are afoot to embed the technology into LCDs, laptops, mobiles and even handheld gaming devices. Dance past the break to hear, and maybe even see, for yourself.

Griffin’s volume-limiting MyPhones can’t crank to 11… or 8

Griffin Technology’s MyPhones are far from being the first cans on the market with volume limiting tech built-in, but unlike some parent-friendly options, these can never, ever be cranked to levels appropriate for ear bashing. You see, rather than giving adults (you know, those Earthlings that are already hard of hearing) the chance to set the limit too high for their offspring, Griffin has implemented an “always-on sound-control circuit to cap peak volume levels at 85 decibels.” That’s the maximum level recommended by many auditory health organizations, and if you don’t like it, tough noogies. But we mean, just look at those two kiddos above — don’t they just look elated? Kidz Bop 14 at barely-audible levels tends to have that effect, or so we hear.

Yamaha neoHD Review: Receiver Redefined? Almost.

For decades, receiver innovation has been stuck in tar, an anonymous group of large black boxes with way too many buttons. Now, the neoHD hopes to re-imagine what the receiver can be.

The NeoHD may support 5.1 surround sound, but it dubs itself a “media connector,” not a receiver. That’s because the model I tested, the YMC-700 ($800), includes ethernet, Wi-Fi and USB drive support. The other big NeoHD revolution is supposed to be its Logitech Harmony-like interface. And the kicker? It’s all managed by the most minimal remote you’ll find in the home theater world.

What’s Really Different with the neoHD?

• graphic-driven interface
• tiny remote
• about half the size of your average receiver
• removes audio modes like Theater, Live, Sports, etc
• gladly supports 2.1 virtual surround or 5.1
• streams web-based radio, network audio
• IR repeaters can control other devices through onscreen remote

Watch, Listen and Play

Every receiver I’ve ever seen is driven by Inputs. You know, HDMI 1, HDMI 2, Component 3. But when you load the NeoHD, you see Watch, Listen and Play. Like a Harmony, the interface is purpose-driven, not device-driven.
Of course you plug in the PS3 through HDMI just like any other receiver, but going through guided setup, the system asks what you want to do with this device. And if it happens that you use it to watch movies, listen to music and play games, guess what? The PS3 will propagate in a submenu under each of those shiny icons.
Herein lies my main problem. I always knew that I wanted to listen to music from my PS3. That was a complete thought. But using the NeoHD’s menus, I need to say, listen to music. Then I need to sort through a list including a slew of other devices. And if I own an Xbox 360, which I do, I need to recall whether the PS3 is Game Console 1 or Game Console 2. (Technically this is the Play menu – I ended up turning off music for both my consoles after encountering the issue.)

I see the intent for a simple UI. But how is this system easier than before? Even the grandma stereotype will be just as lost in this second menu, filled with inputs, as she would be a normal receiver.

Wouldn’t it be better for the main menu just to show an icon of a PS3, an Xbox 360, my satellite dish and whatever else I had around?
To make matters worse, this lack of formal inputs means there’s no input button on the remote. I haven’t been able to find a way to change inputs other than hitting a back button, a la webpage, to slowly back my way to the main screen. The neoHD hopes to replace your universal remote altogether, controlling your TV and cable box through IR blasters. But how can I expect it to replace every remote in the house when it can’t adequately replace itself?

Connectedness

Let’s call the system halfway there.
I found that the neoHD can just as easily play FM as it can stream music from its large library of internet radio stations. But even when streaming music from my Mac (which requires TwonkyMedia Server, bundled free) there’s no way to pause or stop your music, even using a button that brings up onscreen controls. Why can I loop a track but not pause it?

It was also a great disappointment when I realized that the iPod and Bluetooth functions both require external adapters to work. The USB port won’t even charge your iPod.

But the biggest issue that many Giz readers may have is that the neoHD can’t stream video of any sort, nor can it load video from USB. In this regard, the you can’t justify a neoHD purchase knowing that it could replace an Apple TV, Roku, Xbox…you know, anything you use to watch those torrents on the big screen, let alone web content.

Music streaming works, and updating the NeoHD’s firmware couldn’t be easier (it’s basically one button in the settings menu). But ultimately, the AV networking aspects are a bit of a tease without both the A and the V arriving in full force.

Sound

Oh right, this thing drives speakers, doesn’t it? I tested the YMC-700 with 2.1 speakers found bundled with the cheaper, Wi-Fi-less YMC-500. So we’re talking two small front speakers and a subwoofer setup through an automated microphone tone test.
Watching Hero on Blu-ray, the water droplets panned sporadically through the front half of my living room with distinct, round plops, before the clash of swords sliced through atmosphere. The faux surround fills your ears completely, but it only captures the front 150 degrees of your perspective (at least in my living room). Still, I was pleased with the quality. Honestly, voices and shows over DirecTV have never sounded so good, and I use the impressive ZVOX 550 on a daily basis. Not bad.

It’s the Thought that Counts

I know this will sound condescending, but I mean it sincerely. While the neoHD has a flawed UI and limited media support for a media connector, at least Yamaha is trying something new.

There are good ideas here. I’ve never had such an easy time setting up components in any large AV system. And it is inherently easier to manage something like networked audio through your receiver than both your receiver AND your Xbox AND your TV.

But if you’ve already networked your home theater and just want an easy way to add surround sound, you might be better off going with a lower end receiver and a really nice remote. [Yamaha]

Super easy setup


Solid 2.1 performance


Simplified interface often just slows you down


No video codec support whatsoever

Sleek Audio adds phosphorescent glow to wireless CT6 Aura earbuds

Even those with everything probably wish their high-end earbuds had a bit more personality, and if you’re reclined in your Victorian-era sofa in a robe befitting one Chuck Bass nodding in agreement, we’d encourage you to have a gander at Sleek Audio‘s latest. Essentially, these are the same Kleer-enabled CT6 ‘buds that the affluent among us have grown to love, but with an obvious twist. Thanks to the inclusion of phosphorescent particles within the shell and top plate, the $374.99 CT6 Aura can actually glow in a variety of colors, giving DJs around the globe one more reason to ditch the cans and go small. Currently, the CT6 Aura can be ordered in green, blue, orange, yellow and white, with pricing set at $25 more than the standard CT6. Gnarly, right?

Video: KORG places an iPhone pocket in its microSAMPLER, calls it a day

The kids over at Korg are a savvy bunch — they know that the best way to perk up jaded bloggers (such as ourselves) is to somehow attach an iPhone to their device. Unfortunately, what we thought at first glance was an innovative/insane new way to make music on Apple’s flagship handset turns out to be, in fact, little more than a sampler with a pocket for your media player and a 1/4-inch audio input. While we have you here, however, we’d be remiss if we didn’t mention that, as samplers go, this one is pretty awesome. Featuring a 37-key keyboard, a number of sample modes (including autonext mode, which auto-magically slices a beat into individual hits, not unlike Propellerhead’s ReCycle), a preset sound library, 21 KAOS-driven multi-parameter effects, and a USB cable for managing sounds on your Mac or PC (with the included Editor Librarian software), this could be the perfect companion for the microKORG that’s already collecting dust in your bedroom. Of course, Korg wouldn’t be able to sell this thing at Guitar Center without a heavy-handed, borderline silly promo vid (“Suddenly… you receive a gift… FROM YOUR OWN MIND… in the form of: THE PERFECT BEAT”) which we highly suggest you check out after the break. Yours now for $750.

Hard drives quit their day job to pursue new life as a speaker system

We know what you’re thinking, why would you ever turn two decent hard disk drives into tinny speakers when it’s much more logical to use them as storage and buying cheap speakers instead… but if you’re the kind of mad scientist who likes to see doohickeys function outside their intended use, or have friends who’d be really impressed or amused, you might want to consider recreating this classy speaker set complete with transparent glass case and the requisite blue lights. All the instructions lie beyond the read link, and if you’re not quite convinced, we think the video after the break is likely to change your opinion for the better.

Bowers & Wilkins downsizes with Zeppelin Mini iPod speaker

It’s been well over two years since high-end audio outfit Bowers & Wilkins introduced the iPod-lovin’ Zeppelin, and evidently it’s time for a downsizing. Today, the good folks over at B&W slung out the Zeppelin Mini, which promises the same dirigible-inspired sound but in a form factor that fits in a wider assortment of areas. To be honest, this version seems toned down quite a bit on the design side, with the key differentiating features being an updated docking arm and the addition of USB connectivity. Said socket enables direct PC / Mac streaming if your iPod gets lost, and it also enables your ‘Pod to sync with your computer whilst playing back tunes. As for specs, you’ll find a pair of 3-inch full-range drivers, 36 total watts of power, a 3.5 millimeter auxiliary jack and a bundled remote. It’s expected to hit next month for £299 ($495), but you can get acquainted right now by jumping past the break and mashing play.

Ask Engadget: Best headphones for the extreme sports enthusiast?

We know you’ve got questions, and if you’re brave enough to ask the world for answers, here’s the outlet to do so. This week’s Ask Engadget question is coming to us from Ryan, who’s trying to be all humble about his ability to stick a kickflip 1080 while gnawing on a burrito.

“I’m looking for a pair of quality headphones that aren’t seemingly made of glass. The issue is I’m an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I’ve been through the higher quality headsets in the Skullcandy line as these are supposed to be built for “abuse,” which is disgustingly laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn’t really matter, but I need something that can hold up to taking a few hits every now and again. I’m trying to keep ’em under $150. Thanks!”

We have all ideas at least a few readers get out of the house every now and then (don’t let us down here, okay?) and jump on the bike / board / etc., so hopefully those who abuse their cans in a similar fashion can explain which ones hold up. And… go!

Grant Fidelity’s $3,200 Impression II weds CD player, tube amp and overkill

See that? That’s a $3,200 CD player, which will be impossible to justify for pretty much anyone not featured on Joan Rivers’ newest TV show. Designed and produced by Grant Fidelity, the CD-1000 Impression II packs a high-end Sanyo CD drive, tube analog output, tube headphone amplifier and a rather basic display screen, while the “anti-vibration aluminum chassis” tries as hard as it can to look both unorthodox and absurdly expensive. It’s hard to say if your burnt MP3 discs will actually sound better on this thing (okay, so they won’t), but at least you can rest easy knowing that shipping on this 50 pound beast is completely gratis.
