Processor optimizes voice capture

The BelaSigna BR261 voice-processing SoC uses an optimized DSP with an advanced dual-microphone noise reduction algorithm to improve speech intelligibility in noisy environments, while preserving voice naturalness. It supports a conference mode that enables 360° voice pickup and has configurable algorithm performance.

The device operates from a 1.8 to 3.6-V supply and includes a regulator, a PLL, a level translator, and memory. The chip’s input sampling frequency is 16 KHz. Current consumption is 15 ma in active mode and 40 µA in sleep mode and it comes in a small 5.3 x 5.3-mm WLCSP package. ($2 ea/10,000 — samples available now.)
