Overview

BelaSigna® R262 is a complete system-on-chip (SoC) solution that provides wideband single- or dual-microphone noise reduction in voice capture devices such as mobile phones, VoIP application including webcams and tablet computers, two-way radios and other applications that can benefit from improved voice clarity.

Featuring a novel approach to removing mechanical, stationary and non-stationary noise, the chip preserves voice naturalness for greater speech intelligibility regardless of acoustic environment or the orientation of the handheld device while in use—providing unmatched freedom of movement for end-users. Designed to be compatible with a wide range of codecs, baseband chips and microphones without the need for calibration or external components, BelaSigna R262 is easy to integrate, improving manufacturers' time to market.

Additional features include de-reverberation, the ability to customize multiple voice capture modes and outputs and to tune the algorithm to the unique needs of a manufacturer's device. The chip includes a highly optimized DSP-based application controller with industry-leading energy efficiency and is packaged in a highly compact 5.3 mm² WLCSP to fit the most sized-constrained industrial designs.
