Hasta La Gadget!

Do you need to spend a ton of money to enjoy the hell out of movies at home? Nope—that’s a myth. If you want to give your special person’s TV a boost, you can do it on a budget. More »

While more and more devices are beginning to be able to understand what we’re saying, one problem that we face is that not everything that we communicate is in the form of a verbal cue. With that in mind, the roboticists at the Honda Research Institute have been working on a robot that can not only understand words, but other sounds.

HEARBO (the HEAR-ing roBOt) uses a technology called Computational Auditory Scene Analysis to distinguish various sounds from its environment. This allows it to not just pick out verbal communication, but everything from the beep of an alarm clock to the mailman knocking on your front door. It can then use this information to make decisions about what to do.

The specific version of the technology being used for HEARBO is called HARK, an open source library that breaks down the understanding of sounds into three steps: localization, separation and recognition. This allows it to not only distinguish sounds in a noisy location, but exactly where they are coming from. In fact, the technology can nail down the direction that sound is coming from down to 1 degree of accuracy. Currently, the system can distinguish up to four different sounds going on at once, but in theory more microphones could allow it to handle even more sources.

Here’s a short demonstration video showing how the robot can understand what’s going on despite the world’s most annoying alarm clock going off the whole time:

And here’s an example of HEARBO easily distinguishing music from human commands, identifying song attributes, and even dancing a little bit:

So why develop such a robot? The technology could be used for things like robot butlers that could automatically answer the doorbell, or do things like turn off the TV if the kids have been using it for too long.

The CinemaCon crowd may not have been keen on 48fps footage of The Hobbit: An Unexpected Journey, but we defy anyone to say they don’t want the best sound possible. A select few will get just that, as Dolby and Peter Jackson’s own Park Road Post Production have announced the film will be mixed for the speaker-packed Atmos technology. If you’re lucky enough to live near one of the select establishments it’s installed in, we doubt you’ll be grumbling about the immersive audio, even if the frame rate makes those orcs look unsettlingly real.

Update: That link of “select establishments” is somewhat out of date and, although the official list of locations you’ll be able to see The Hobbit in Atmos has yet to be released, Dolby says there should be between 80 and 100 screens capable of delivering the over-the-top audio experience by the film’s debut.

It’s official. Aside from letting loose its first set of headphones post-Monster for the Executive types, Beats Electronics has set its sights on nabbing the portable Bluetooth audio crown from Jawbone’s Jambox. You’ll recall this hitting the FCC a bit ago, but today the Dr. is officially ready to offer you it’s remedy for on-the-go wireless audio with its $200 Pill, an NFC-equipped portable Bluetooth 2.1 speaker. Coming in your choice red, black or white, the cylindrical system is loaded with a quartet of 1-inch drivers, and supports codecs including Apt-X and AAC. An internal battery is said to provide about seven hours of listening at around 75-percent volume (80 decibels), and the unit can be charged via its Micro-USB input. Notably, an auto-off feature turns the unit off after 30 minutes if no audio is streamed to it. As you’d expect, the Pill features a front-facing on-board mic for use as a speakerphone, physical volume buttons and power button, as well as a 3.5mm input if you’d like to play sans Bluetooth. We’re also pleased to notice that the diminutive system also features a 3.5 output if you’d like to send the audio out to another audio ware. The Pill comes with a 3.5mm to 3.5mm cable, a USB to Micro-USB cable for charging with an included wall adapter and, lastly, a carrying shell case that can be hooked to a bag.

We’ve been able to spend about an hour with the system, and we’ve frankly come away very impressed. The unit feels very sturdy, with a stiff metal grille and soft-touch coating around the rest of its exterior. It feels very comfortable to hold in a hand, and will easily fit in a jacket pocket. Actually, one of our only initial complaints is that the included carrying shell doesn’t leave any room for the included cables. All of the buttons have a soft, slightly clicky tactility, which also aids to its premium feel. Using it initially alongside one of Beats’ on-hand Jamboxes in a wired A/B comparison, the Jambox came out sounding like a distorted, rumbling mess up against the pill — we even had a rep bring out a second unit confirm that it wasn’t a dud. If that wasn’t enough, the Pill also managed to get much louder, staying fairly clean (in comparison), and without rumbling on the table as the Jambox did very slightly. As a triple-check measure, we later came up with a similar outcome with our in-house unit of Logitech’s $99 UE mobile boombox — a speaker we find comparable in sound, if slightly better, than the Jambox.

In what could be viewed as slightly ironic, the Pill has a voicing that edges toward the flatter side of things, rather than pumping out exorbitant amounts of bass. It’s not to say that it can’t reproduce bass at all, it’s just not the focus here. This flatter output seems to be a big part of what keeps it from distorting, but we should be clear, that the audio here is many times better still on the Pill. Pleasantly, the speakers are also angled up slightly, which makes for a noticeably more natural listening experience. Our only other concern for the time being is that the Bluetooth connection with our iPhone 5 did crackle occasionally like a vinyl record, but it’s too early to say if the issue will be consistent during future use. We’re still a ways off from being able to definitively give you a thumbs up on the Pill, but — at least, initially, it seems like it’s easily blowing the Jambox and similar speakers out of the water. Like the Executive headphones, the Pill is available today at Beats stores and other retailers — check out our video hands-on after the break for a better look.

Technologies like NFC, RFID and QR codes are quickly becoming a normal part of everyday life, and now a group from Carnegie Mellon University has a fresh take on close-quarters data it calls acoustic barcodes. It involves physically etching a barcode-like pattern onto almost any surface, so it produces sound when something’s dragged across it — a fingernail, for example. A computer is then fed that sound through a microphone, recognizes the waveform and executes a command based on it. By altering the space between the grooves, it’s possible to create endless unique identifiers that are associated with different actions.

It’s easy to see how smartphones could take advantage of this — not that we recommend dragging your new iPhone over ridged surfaces — but unlike the technologies mentioned earlier, not all potential applications envisage a personal reading device. Dot barcodes around an area, install the sound processing hardware on site, and you’ve got yourself an interactive space primed for breaking freshly manicured nails. We’re pretty impressed by the simplicity of the concept, and the team does a good job of presenting scenarios for implementing it, which you can see in the video below. And, if you’d like to learn a little more about the idea or delve into the full academic paper, the source links await you.
