Audience Inc. has uncloaked what it boasts as the world's first smart sound processor. According to the company, the earSmart eS515 Smart Sound Processor combines its third generation Advanced Voice processing technology with its first low-power audio codec. The sound processor delivers best in class voice, speech recognition and multimedia experience on a mobile device, added the company.

The earSmart eS515 Smart Sound Processor targets more sophisticated mobile devices with greater processing power, slimmer designs, larger displays and advanced multimedia features. The device offers simultaneous 3-microphone processing, optimised automatic speech recognition (ASR), Mobile Audio Zoom and Super Wideband support for Voice over IP (VoIP), combined with a robust audio codec designed specifically for the newest mobile devices, the company indicated.

According to the company, the earSmart eS515 supports high sample-rate VoIP calls, offering the industry's best voice quality for narrowband and wideband networks. It is also the first sound processor to offer de-reverberation for mobile devices, removing the echo effect in spaces such as conference rooms and hallways, added Audience.

The ASR Assist technology from Audience directly addresses the challenge faced by many speech recognition applications such as the failure to recognise spoken words and complete assigned tasks because of disruptive background noise. The company also stated that the earSmart eS515 uses custom hardware-accelerated algorithms to isolate voice from surrounding environmental noise, dramatically improving the user experience of speech-enabled applications such as virtual assistants and voice search.

The earSmart eS515 Smart Sound Processor claims to feature the world's first multi-microphone 48kHz noise suppression implementation for the recording of clean, HD audio. It also features Audio Zoom that allows users to dynamically switch between narrate mode, with a single speaker, to interview mode, where the person holding the device can interview another person. Interview mode leverages Audience's industry leading background noise reduction technology to capture both voices with crystal clear accuracy, Audience stated.

The solution includes an Audience Advanced Voice Processor core and a hardware accelerator engine, optimised to run computationally intensive audio algorithms with low power consumption. In addition, the earSmart eS515 processor includes a codec sub-system that consists of multiple ADCs and DACs, as well as stereo class D speaker drivers, stereo class G headphone drivers, an earpiece driver and two line outputs.

The earSmart eS515 is sampling to customers globally.
