Audience Inc. has announced the release of its latest earSmart voice processor, the eS30, for the tablet market. The eS305 is designed to support voice enhancement and handheld speakerphone noise suppression over wideband 4G networks. According to Audience, this enables high-definition (HD) voice quality, giving tablet users clear, life-like converzations for video chat, VoIP and mobile calls over broadband WiFi and 4G wireless networks.

"Feature-rich devices like tablets, and expanding wideband network access, are creating new ways to connect, with video communication and more, and therefore, increasing the need for voice technology that can ensure the highest voice clarity and sound quality. Tablet devices are different because communication often occurs with the device held away from the user, which requires a new level of advanced voice processing to provide a good user experience," said Peter Santos, president and CEO of Audience. "The earSmart eS305 chip now offers capabilities to enable true HD voice quality in tablets and other devices over wideband networks, delivering clear, noise-free communications wherever you choose to talk."

The earSmart eS305 voice processor is based on the human hearing system, and delivers unique signal enhancement capabilities that provide wideband HD voice and audio quality, with wideband non-stationary noise suppression to remove noise from both ends of a call, even when the device is used in speakerphone mode. It also provides acoustic echo cancellation and automatic voice equalization to further improve mobile call quality.

For device manufacturers, the earSmart eS305 voice processor can be easily customizable to create a differentiating, signature sound. It is also designed for seamless integration into tablet system architectures, featuring all-digital interfaces for performance and flexibility, with graphical design tools to facilitate design-in. Offering a custom high-performance, low-power Audio DSP, Audience claims that its earSmart eS305 chip is highly consistent and robustacross all device usage modes, wideband and narrowband 2G or 3G wireless networks, and changing orientation from landscape to portrait.

The earSmart eS305 processor also provides a compact 3.5mm x 3.5mm, BGA (0.5mm pitch) package that can fit any mobile device form factor or design and easily integrates into existing mobile tablet or phone architectures.
