Raising the IQ of Multiroom Smart Speakers

Raising the IQ of Multiroom Smart Speakers

Share

At CES this year, many products on the show floor, from microwaves to automobiles, had either Alexa or Google Assistant (or both!) built in. And from what we saw, multiroom, Wi-Fi speakers were no exception. Since Amazon unveiled their flagship voice-activated smart speaker, Echo, in 2014, the audio industry has been drastically shaken. Although they don’t generally produce the best sound quality, smart speakers have become hugely popular. And now, many smart speakers are gaining hi-res audio abilities, like Google Home Max and Apple’s HomePod. And that’s got audio manufacturers worried. In a market dominated by smart speakers (in addition to the roll-out of smart speakers with enhanced audio abilities) CE companies have no choice but “to stay relevant in a Wi-Fi speaker market dominated by Amazon- and Google-branded smart speakers” by designing products that “feature microphones to detect voice commands and come with either Amazon Alexa or Google Assistant built in” (Sound and Vision).

 

While most audio manufacturers begin to launch multiroom Wi-Fi smart speakers that either incorporate or compete with Google and Amazon’s technology, here are a few key concepts to keep in mind:

 

Buffering Bummer

Most popular wireless speakers run on conventional Wi-Fi protocols which have to queue the data. This means that it takes several seconds for the first song to fill the buffer before it begins to play. While the first song plays, the system is already buffering the next song to minimize gaps. This is fine until you change the queue before the system can re-buffer. This certainly poses a problem for folks who want to use these wireless, smart speakers in a multiroom set up. Enter Real-Time Packet Management (RPM): the Blackfire solution to buffering. RPM uses a special multipoint, real-time feedback signal from each speaker to monitor the effects of noise on the audio data stream, which allows a much shorter queue and much less buffering.

 

Get In Sync

Regardless of how “smart” a Wi-Fi speaker is, problems will always arise when it comes to synchronizing multiple speakers in a multiroom set up. Problems facing a standard method of synchronization include: 1) performance that is tied to the performance of the network environment and 2) the more devices you have on a given network, the slower it runs, producing an extended lag between speakers and between your TV and the speakers – even total dropouts. Traffic Independant Synchronization (TIS) is Blackfire’s patented synchronization technology that can be used to sync any number of wireless devices, from multi speaker 5.1 audio systems, stereo systems, smart speakers, and even your entire home theater. Blackfire’s TIS technology always maintains latency between audio and video pairings and among the speakers themselves. And with TIS, the sync of the speakers will remain undisturbed by heavy network traffic.

 

Interfere Interference

Wireless, multi-speaker systems that use conventional Wi-Fi protocols are more susceptible to interference and heavy network traffic, which causes music to break up and for speakers to go out of sync. Dynamic Stream Balancing (DSB) is the way Blackfire makes the best use of the available Wi-Fi bandwidth. DSB monitors special multipoint, real-time feedback signals from each speaker to identify the effect of noise on the audio data stream. By precisely identifying which packets are statistically most likely to be affected, DSB uses the available Wi-Fi bandwidth to selectively, and predictively, resend data to the most vulnerable speaker before interference can cause any audible drop out.

 

The Blackfire Realtime Entertainment Distribution (RED) framework

Combining individual entertainment systems to work together (to create a truly connected smart home) is non trivial – it requires precise synchronization, low latency for lip sync and a general reliability over standard Wi-Fi (the best and most commonly used communication protocol for the home.) With The Blackfire Realtime Entertainment Distribution (RED) framework embedded into wireless smart speakers, users can finally enjoy a truly connected home. With voice commands, you can ask any Blackfire enabled device to play music, wirelessly and synchronously throughout the home, in groups, and on multiple devices. The Blackfire RED framework also supports low latency and multi-channel, which other wireless solutions do not.

 

Voice service solutions require a high performance, multi-room solution like the Blackfire RED framework, which can allow multiple devices to respond to voice commands, simultaneously, and can be integrated into a broad spectrum of high quality voice service applications.

 

The Blackfire RED framework enhances the performance of smart speakers and does what no other solution has done before. Our partners have already stepped into the future, leveraging Blackfire’s technology in their products. Now is your chance, too. Join the Blackfire revolution today.

CES 2018 Wrap Up

CES 2018 Wrap Up

Share

Blackfire Research is back from Las Vegas, where we spent the entire second week of January at the annual Consumer Electronics Show (CES). This year was packed with productive meetings in our official CES Suite at The Venetian Hotel and Casino. However, we did manage to get down to the Sands Expo and Las Vegas Convention Center to check out all the cool, new tech for 2018 – here’s what we saw at CES this year and our takeaways from the show:

 

Hey Google

If last year’s CES was dubbed “The Amazon Home Takeover,” this year could be summarized by one simple greeting: “Hey Google.” The search engine giant was everywhere this year: literally. They had a massive 3-story booth right outside the convention center, and at every booth that featured products touting Google Home smart speaker/Google Assistant functionality, a Google representative was there, donning a white jumpsuit fresh out of George Orwell’s dystopian vision of 1984. But Google’s overwhelming presence at the show paid off: this year, all eyes were on them. From Whirlpool appliances to smart speakers with video displays, you couldn’t escape the latest “Google Home Takeover.” Amazon was present at CES of course (Whirlpool also featured appliances with Amazon’s Dash Buttons built-in, which is pretty neat and useful) but if a winner had to be chosen for CES 2018, Google would be voted “Best in Show.” Speaking of which…

 

All (Robot) Dogs Go to Heaven

Sony has brought back their popular Aibo robot dog and everyone at the show couldn’t have been happier. This very good boy is new and improved for the AI age with a camera on his nose so he can recognize members of his family (awww) and find his bone (awww). He also features a camera on his back to help him navigate the house to find his charging station. With touch sensors on his head, back, and chin, he can respond to touch like any ‘ol dog would: by wagging his tail, moving his head, and stomping his widdle feeties. With his adorable LED-lit eyes, this is by far the best, and most realistic, pet robot on the market. Unfortunately, Sony hasn’t announced plans to sell Aibo in the US anytime soon. Doggonit!

 

A Picture’s Worth A Thousand Words…

This year, we’ve officially stepped into the world of 8K. But since 4K is barely a thing yet (because there’s hardly any 4K content available still) Samsung has gone around the issue of total lack of 8K content by unveiling it’s Q9S 8K TV with AI Upscaling, meaning, that this TV can convert any content into 8K resolution. And from firsthand experience, we can tell you that 8K resolution is pretty darn good. The picture was so incredibly clear that jaws dropped during the demo. Another Samsung showstopper this year was their enormous, bezel-less The Wall: a 146-inch modular MicroLED TV.

 

Honorable Mentions & Takeaways

5G cellular technology, the latest and greatest approved standard, wasn’t on display much at CES this year, mainly because the hardware needed for it isn’t quite ready yet. There were a few booths demonstrating it’s super-fast capabilities, but overall, it was all quiet on the 5G front at CES. But don’t expect that to last long: with 5G technology coming to the main service providers fast, it’s sure to be all the rage at next year’s event.

 

Once again, this year’s CES felt more like a car show than anything, with a plethora of smart, autonomous vehicles on display (some of which seemed to be taken straight from an episode of Black Mirror). Also, Wireless charging was big this year, especially since Apple announced their commitment to the Qi Wireless Charging standard last September.

Overall, between the rain and loss of power, this year’s CES was a bit chaotic. But we still managed to see some pretty neat tech that was useful, inspiring and – we hope – becomes available soon (we’re looking at you, Aibo!)

This past year, consumer electronics company, HTC, began shipping the HTC Bolt, the HTC U Ultra, and the HTC U11 smartphones with built-in HTC Connect powered by Blackfire’s wireless multi room technology. Now, HTC has added two more smartphones to the mix: the HTC U11 Life and the HTC U11+, both with HTC Connect, powered by Blackfire.

 

The HTC U11 Life is a more compact, less expensive version of the company’s widely popular HTC U11 smartphone, while the HTC U11+ is a larger, updated version of it with higher-end finishes, a 6-inch screen, and bigger battery. The U11+ is one of the first smartphones to ship with the Android 8.0 Oreo operating system out of the box, while the U11 Life runs on the Android Nougat with HTC Sense in the US. Both phones feature the Edge Sense, which was first introduced in the HTC U11, allowing users to trigger an action, such as summoning Google Assistant or Amazon Alexa, by squeezing the sides of the phone. Neither the U11 Life nor the U11+ have a headphone jack (RIP), which seems to be the trend on most smartphones nowadays. But HTC is giving audio quality a huge boost on the U11+, with 30% more volume than the flagship U11, better dynamic range and less distortion.

 

And of course, both the HTC U11 Life and the U11+ both feature HTC Connect, powered by Blackfire, which can stream any local or web-based music or video via Wifi from an HTC smartphone to any Blackfire powered stereo device, wireless multi room speakers, or entertainment system by swiping up the home screen with three fingers. With HTC Connect, users can create a wireless 5.1 surround sound system or stream different music to multiple speakers at the same time. (Check out this easy guide to help you wirelessly stream music from an HTC U11 smartphone to Blackfire compliant speakers.) Setting up your wireless home entertainment system has never been easier.

The HTC U11 Life is available in the US and can be purchased here.

Meet Google Home Mini and Google Home Max

Meet Google Home Mini and Google Home Max

At their recent hardware event, Google announced two new additions to their smart speaker agenda, both of which are ready to take on the ever-increasing number of competitors in the field. Say hello to the Google Home Mini and the Google Home Max.

 

The Google Home Mini has the same functionality as the original Google Home, but at a fraction of the size (and cost). With voice command, you can ask Google Assistant to stream music, control your smart home, check your calendar, and search the internet. The Mini is nearly 4 inches in diameter (roughly the size of a hockey puck), with the top portion covered in fabric, which is available in three colors: chalk, charcoal, and coral. The fabric hides the speaker (1.5-inches) and a far-field voice-recognition microphone. The design is pretty simple and sleek (although as a cat-parent, I wonder how much hair that fabric covering will collect over time). The Mini is a direct response (and a direct competitor) to the Amazon Echo Dot, the cheaper, more popular version of Amazon’s flagship Echo smart speaker. Will The Mini overtake Echo Dot as the most popular pint-sized smart speaker? According to some reviews, The Google Home Mini certainly sounds better than the Echo Dot (it boast 360 degree sound with a 40mm driver), but in overall functionality, there isn’t much of a difference between the two. At $49, the Mini is the cheapest smart speaker option currently on the market.

 

The biggest announcement of the day, however, belonged to the introduction of Google Home Max, a premium version of the Google Home smart speaker designed to compete against Apple’s HomePod and Sonos. The Home Max is a stereo speaker that runs Google Assitant and looks quite similar to the Sonos Play:5 speaker. The speaker is designed to intelligently adjust audio depending on a user’s surroundings using AI (or what Google calls “Smart Sound”), similar to what Apple’s HomePod speaker does. The Max has two tweeters and two 4.5-inch woofers and the company has emphasized the speaker’s powerful bass. The Max supports multi-room audio via Chromecast Audio only, but supports many streaming services including Pandora, Spotify, and iHeartRadio. In terms of connectivity, the Home Max supports Wi-Fi, Bluetooth, and Chromecast. At roughly 12 pounds, this is by far the largest smart speaker on the market, and the priciest as well. The Google Home Max will set you back almost $400, but Google is giving away 12 months free of YouTube Music with every Home Max purchase. The speaker will be available in two colors: chalk and charcoal, and can be displayed both vertically or horizontally via an adjustable silicon base.

 

The real question is: will the Google Home Max sound as good as the company claims? The answer is, most likely, no. Smart speakers don’t have a very good track record when it comes to audio quality. That’s why many smart speaker owners look for alternative ways to playback their music, especially for multi-room. To achieve excellent wireless multi-room, or multi-device set ups, entertainment systems need greater reliability over standard Wi-Fi, more precise synchronization, and multichannel capabilities, which smart speakers like Google Home, and the Echo, lack.

 

The good news: Blackfire Research offers the most synchronous, reliable, and cost effective wireless solution on the market. We call it the Blackfire RED framework, and it can be embedded into premium wireless speakers and voice-activated smart speakers, creating a truly connected home smart entertainment system. Voice service solutions require a high performance, multi-room solution like the Blackfire RED framework, allowing for multiple devices to respond to voice commands simultaneously.

 

Combining individual entertainment systems to work together to create a truly connected smart home is non trivial – but with Blackfire RED, it can be done, and with stunning results. Blackfire RED can be integrated into a broad spectrum of high quality voice service applications, so the Blackfire connected smart home ecosystem has no limits.

Amazon Unveils Next Gen Echo Products

Amazon Unveils Next Gen Echo Products

Share

Recently, Amazon unveiled a plethora of new Echo products. From a true smart home hub to buttons that will come in handy during your next family game night, here is everything that Amazon unveiled at their September 27th event, and what it means for the future of the smart home.

 

Amazon has officially retired their original Echo smart speaker (RIP: 2014-2017) and replaced it with a second generation version at $99. The first update to the world’s most popular smart speaker sees a shorter, more compact design and a dedicated bass tweeter. The new Echo will come in six different styles: Charcoal, Heather, and Sandstone fabric or Walnut, Oak, and Silver finish. More importantly, Amazon is promoting an Echo “three-pack” for multi-room audio. The company first announced multi-room audio capabilities back in August, but have only started to heavily promote the feature with the unveiling of the new Echo smart speaker. There hasn’t been much testing yet of the new multi-room feature, so the jury is still out on whether or not Echo provides a synchronous, reliable performance across all devices throughout the home. Unlike Blackfire RED framework enabled smart devices, the Echo can not support multi-channel or low-latency for audio/video lip sync.

 

Additionally, the Echo is now able to make calls throughout North America. Amazon clearly wants the Echo to replace your home phone, and to help push the idea, they’ve also introduced the Echo Connect – a device that is tied to your existing home phone number that allows you to make landline calls through Alexa.

 

Amazon also rolled out the Echo Plus, which looks more like the original Echo than the Echo 2.0. The Echo Plus is the first one specifically designed to be used as a true smart home hub. With it, you can control compatible smart lights, locks, and thermostats. The Echo Plus also uses Zigbee so it’s compatible with more smart devices on the market. The Echo Plus has updated voice-recognition so you can talk to it from further away or in noisy settings, and more advanced speakers. Price-wise, the Echo Plus is comparable to the original Echo, at $149.

 

Amazon also introduced the Echo Spot, a sort of smart alarm clock with a 2.5-inch screen, that can be placed anywhere in the house and can be used for more than just an alarm in the mornings. The Echo Spot can make video calls and can play music through it’s own speakers or connect to external ones via cable or Bluetooth. The Echo Spot can do pretty much anything the Echo can do, but it’s much more compact and it has a screen. But this isn’t the first (and only) Echo product with a screen: Amazon released the Echo Show earlier this year to not overly positive reviews. Now, it seems that they’ve simplified and improved their interface for the Echo Spot. And at $130 for this little gadget, they needed to.

 

Lastly, Amazon introduced Echo Buttons: little discs that connect to your Echo device that you can use to play trivia games with your friends and family (with Alexa as the game-show host). The Echo Buttons light up in cool colors and can be purchased in pairs for $20.

 

So what does this mean for the the smart home of the future? Well, for one thing, Amazon has, once again, positioned itself to be the leader of smart home technology. However, they’ve got some serious competition. Google has also unveiled a whole new suite of products (which we will discuss in a later blog post) that may give Amazon a run for their money. As more and more smart home devices are gaining in popularity, it’ll be interesting to watch how manufacturers choose to align their brands and products with either Alexa or Google Assistant (or perhaps both). The war rages on!
