Tensilica and Acoustic Technologies Extend Partnership to Deliver Complete Wideband HD Voice Processing Solution for Smartphones, Tablets and Other Mobile Computing Devices

Tensilica's HiFi Audio/Voice DSP and Acoustic Technologies' SoundClear Voice Solution Shipping in Leading Smartphones to Provide Optimal Speech Intelligibility

SANTA CLARA, CA -- (Marketwire) -- 02/13/13 -- Tensilica®, Inc., the leading licensor of audio/voice DSP cores, and Acoustic Technologies, Inc., a worldwide leader in high quality voice processing solutions, are delivering HD voice to the mobile market and will demonstrate their solutions for smartphones, tablets and mobile computing at booth 6-D101 at the Mobile World Congress in Barcelona from February 25 - 28. Acoustic's wideband SoundClear® Voice software has been optimized for the HiFi family of DSP (digital signal processing) cores to provide advanced multi-mic noise reduction and full-duplex speakerphone performance. SoundClear Voice is shipping today in leading smartphones and other mobile devices and accessory products.

"Acoustic's SoundClear Voice solutions are broadly adopted by leading consumer electronics vendors," stated Larry Przywara, Tensilica's senior director of multimedia marketing. "Their HD voice solution ensures mobile users get the best possible call quality as network operators and mobile device makers rollout wideband HD voice on their networks."

Acoustic Technologies' voice processing solution is proven with tier one smartphone vendors, and the world's largest network operators, to deliver high quality voice performance in handset, speakerphone and headset modes. The HD multi-mic noise cancellation includes Acoustic's InstantAdapt™ feature, dynamic microphone balancing technology and FlexEQ™ equalization to deliver clear speech anywhere. Wideband voice doubles the sampling rate of narrowband voice to deliver expanded frequency response at both lower and upper ends of the voice spectrum. The dramatically improved voice quality improves the user experience on mobile networks that have deployed HD voice and for VoIP applications. The improvements in sound fidelity and clear speech also improve recognition rates in noise for ASR (automatic speech recognition) applications.

"The HiFi DSPs are ideal for running our advanced HD voice solutions for smartphones requiring best-in-class multi-mic noise reduction and speakerphone performance," said Bob Ackmann, CEO of Acoustic Technologies. "The HiFi DSPs offer leading DSP performance, low power and high quality tools that enable us to deliver optimized wideband voice solutions to our customers."

Tensilica's HiFi Audio/Voice DSPs are the leading audio/voice DSP IP cores, licensed by over 50 customers including five of the top 10 semiconductor manufacturers and many leading system OEMs. The HiFi Audio/Voice DSPs support over 100 audio/voice software packages with very efficient processing at low power and they are part of Tensilica's growing line of dataplane processors (DPUs) that efficiently do the challenging, compute-intensive tasks in SOC designs.

@CloudExpo Stories
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Ben Perlmutter, a Sales Engineer with IBM Cloudant, demonstrated techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user e...
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem"...
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now ...
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true ...
The buzz continues for cloud, data analytics and the Internet of Things (IoT) and their collective impact across all industries. But a new conversation is emerging - how do companies use industry disruption and technology enablers to lead in markets undergoing change, uncertainty and ambiguity? Organizations of all sizes need to evolve and transform, often under massive pressure, as industry lines blur and merge and traditional business models are assaulted and turned upside down. In this new da...
There are over 120 breakout sessions in all, with Keynotes, General Sessions, and Power Panels adding to three days of incredibly rich presentations and content. Join @ThingsExpo conference chair Roger Strukhoff (@IoT2040), June 7-9, 2016 in New York City, for three days of intense 'Internet of Things' discussion and focus, including Big Data's indespensable role in IoT, Smart Grids and Industrial Internet of Things, Wearables and Consumer IoT, as well as (new) IoT's use in Vertical Markets.
In today's enterprise, digital transformation represents organizational change even more so than technology change, as customer preferences and behavior drive end-to-end transformation across lines of business as well as IT. To capitalize on the ubiquitous disruption driving this transformation, companies must be able to innovate at an increasingly rapid pace. Traditional approaches for driving innovation are now woefully inadequate for keeping up with the breadth of disruption and change facin...

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningf...
