NXP Software deployed LifeVibes VoiceExperience on the Samsung Galaxy Note II. The solution illustrates the successful, seamless integration of LifeVibes VoiceExperience on the Qualcomm MDM9615 LTE modem used in the Samsung Galaxy Note II for the Korean market. LifeVibes VoiceExperience is fully API compatible with the Qualcomm QDSP Elite framework. This allows Samsung to integrate the software without having to make any changes to the framework, therefore enabling a short time to market.
Benchmark tests carried out by Samsung showed that VoiceExperience delivers a superior performance compared to competing solutions. The improvement is particularly noticeable when calling with wideband mode (known as HD Voice), as well as in speakerphone mode. A good, full-duplex speakerphone performance is especially difficult to achieve, as the loudspeaker volume is high and strong echoes are typically present.
LifeVibes VoiceExperience enables natural, comfortable communication over phone networks and IP-based channels such as Skype and Google Talk. It improves the intelligibility of speech, eliminates echo and distortion, and minimizes stationary and non-stationary background noise (such as traffic or crowds). VoiceExperience software is available on all the popular hardware and software platforms, and uses the same proven engine for voice calls, video telephony and VoIP, and is HD Voice compatible.
NXP Software’s LifeVibes SoundExperience solution has been made available as part of the multimedia software stack offered in Intel® Smartphone Reference Designs. With LifeVibes SoundExperience solution, users can enjoy their music and movies with an enhanced audio listening experience, including bass, treble, equalizer and 3D surround effect, all available from an intuitive user interface. Effects include enhancements for mono, stereo speakers and headphones. Unique audio software enhancement is also provided to maximize the speaker(s) loudness, without any increased risk of damaging the speaker(s) of the device.
The LifeVibes SoundExperience solution is a pre-integrated pluggable component in the multimedia software stack of Intel’s smartphone reference design models, and can be made available to any OEM running an Intel Atom-based Android OS platform, with zero-integration effort. The Intel reference software stack containing LifeVibes SoundExperience solution will be available on platforms based on the Intel® Atom™ processor Z2420 (Lexington); Intel® Atom processor Z2460 (Medfield) and the just announced Intel® Atom™ processor Z2580 family (Clover Trail+).
“The NXP SoundExperience solution provides best-in-class audio rendering delivering improved clarity and loudness of music on Intel-based smartphone platforms,” said Chris McGuire, General Manager—Reference Devices, Intel Mobile and Communications Group.
Pantech adopted the Lifevibes SoundExperience solution as part of the multimedia software stack of their Android smartphone devices. With LifeVibes SoundExperience solution, users can enjoy their music and movies with an enhanced audio listening experience, including bass, treble, equalizer and 3D surround effect, all available from an intuitive user interface. Effects include enhancements for mono, stereo speakers and headphones. Special audio software enhancements are also provided to maximize the loudness of the device without any increased risk of damaging the speaker(s) of the device.
Already one model is deployed in the US market: the Pantech Discover model, based on a Qualcomm MSM8960 chipset. LifeVibes SoundExperience running on Discover got AT&T approval and the phone is now available on the US market.
“We are getting very positive user feedback on the audio effects and rendering enabled by LifeVibes SoundExperience running on the Pantech Discover”, says Gary Cherner, Vice President of Sales, Marketing and Product planning for Pantech North America, continuing with “Our attention is now turning towards power consumption, and Pantech and NXP Software Engineering are working together to reduce the power consumption down to minimum levels for background music playback using the LPA or Low Power Audio, a Qualcomm chipset capability”.
NXP Software’s LifeVibes VoiceExperience is available and optimized for Tensilica’s HiFi Audio/Voice DSP family. LifeVibes VoiceExperience offers a rich set of proven voice enhancements for clear, natural calling. Tensilica’s HiFi DSP family is the most widely-used licensable audio/voice DSP family, with support for over 100 proven audio/voice software packages. Over 50 companies have licensed Tensilica’s HiFi DSP family, and they’ve shipped over 200 million HiFi DSP cores in their smartphones, tablets, computers, digital televisions, home entertainment systems, and other devices.
“The Tensilica HiFi Audio/Voice DSP family combines an efficient, low-power architecture with robust and well-supported development tools,” stated Nicolas Sauvage, OEM Business Line Director, NXP Software. “Combined with our LifeVibes VoiceExperience software, we offer a complete solution for leading OEMs who wants to offer the highest quality voice enhancements for clear, natural calling.”
“A number of our licensees have asked for LifeVibes VoiceExperience support on HiFi because they’ve already designed HiFi into their products and need better voice enhancement support. We are excited to offer our mutual customers this optimized software package, as it is proven in over 750 million handsets and tablets,” stated Larry Przywara, Tensilica’s senior director of mobile multimedia. “By fully optimizing it for our HiFi architecture, designers can be assured of the lowest power, most efficient yet premium voice experience.”
LifeVibes VoiceExperience software runs on CEVA’s new AMF. The new software framework integrates CEVA DSPs with Android OS, allowing seamless offload of intensive multimedia tasks from the main CPU, and enabling advanced low-power application development for audio, voice, imaging and vision related functions. CEVA introduced a new low-energy software framework for Android based systems, which efficiently reduces the power consumption required for complex multimedia processing using a heterogeneous CPU and DSP system architecture. Known as Android Multimedia Framework (AMF™), the framework addresses the most intensive, real-time signal processing applications, including audio, voice, imaging and vision, and seamlessly offloads the related tasks from the CPU to the CEVA DSPs at the Android Operation System (OS) level. Previously, the DSP was detached from the Android OS, requiring system programmers to implement multimedia tasks and partitioning at the CPU level, resulting in inefficient use of the CPU to perform complex, power hungry DSP tasks.
Eran Briman, vice president of marketing at CEVA, commented: “This comprehensive software framework bridging our application-specific DSPs to the Android OS is an important milestone for our customers utilizing CEVA’s DSPs and multimedia platforms. AMF was developed in close collaboration with the CEVA ecosystem of software, system and silicon vendors, contributing their vast expertise to the design process. The benefits of enabling Android developers direct access to the processing capabilities of our DSPs are huge, delivering significant power savings for signal processing-intensive tasks and enabling the development of a whole new generation of applications for audio, voice, imaging and vision, which were not practical to implement on CPU centric architectures.”
