Audience Brings Advanced Voice and Audio to Mobile with earSmart eS515


By SIP Trunking Report Contributing Writer



Audience Inc., a manufacturer of advanced voice and audio processing solutions for mobile devices, recently unveiled the earSmart eS515, which the company claims is the world’s first smart sound processor. This device combines the company’s award-winning Advanced Voice processing technology with a new high-performance, low-power audio codec for an all-around high quality audio experience suited to mobile devices.


The earSmart eS515 also sports a number of features that have become more widely demanded in recent years, including simultaneous three-microphone processing, optimized Automatic Speech Recognition (ASR), mobile audio zoom and super wideband support for VoIP. These features, combined with the earSmart eS515’s advanced audio codec, allow it to handle nearly any mobile device scenario where audio is involved.

“The earSmart eS515 Smart Sound Processor is the first product to offer our Advanced Voice technology integrated with a complete audio codec subsystem – it takes us to the next stage in sound processing, providing our customers with a level of performance, integration, efficiency and auditory presence never before experienced,” said Peter Santos, president and CEO of Audience, in a statement.

The earSmart eS515’s three-microphone array allows for the gathering of more environmental information for superior voice quality. This, combined with support for high sample rate VoIP calls, ensures the best voice quality on narrow and wideband networks.

Meanwhile, ASR Assist technology helps overcome issues with speech recognition by way of custom hardware-accelerated algorithms which isolate voice from ambient noises. The result is greater reliability with speech-based programs such as Siri. Likewise, 48KHz noise suppression allows for the recording of clean HD audio, while audio zoom offers selective audio capture with narrate and interviews modes.

In other words, the earSmart eS515 can provide a mobile audio experience superior to previous technologies in the same line, such as the earSmart eS305 Advanced Voice processor that was used in the Nexus 10 tablet developed by Google and Samsung.
