Audience Unveils eS305 Voice Processor for Tablets

Audience, Inc., a global provider of intelligent voice and audio processors for mobile products, has announced its latest earSmart™ voice processor for the tablet market. A low-power, high performance solution to improve voice communications and sound quality in tablets, the eS305 chip is designed to support voice enhancement and handheld speakerphone noise suppression over wideband 4G networks. This enables high definition (HD) voice quality, giving tablet users clear, life-like conversations for video chat, VoIP and mobile calls over broadband Wi-Fi® and 4G wireless networks.


The earSmart eS305 voice processor is based on the human hearing system, and delivers unique signal enhancement capabilities that provide wideband high-definition (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 voice-enhancing features such as acoustic echo cancellation and automatic voice equalization to further improve mobile call quality.


The earSmart™ eS305 voice processor is 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’s earSmart eS305 chip is highly consistent and robust – across all device usage modes, wideband and narrowband 2 or 3G wireless networks, and changing orientation from landscape to portrait.
