A professional 4‑mic circular array based on the XMOS XVF3800, engineered for clear target voice capture in noisy environments. It supports dual operating modes and delivers 360° far‑field voice pickup (up to 5 m) with a complete DSP pipeline: AEC, AGC (60 dB), DoA, VAD, de‑reverberation, beamforming, and noise suppression. Encased for durability (no exposed PCBs), the array is plug‑and‑play via USB and ideal for smart conference rooms, voice‑controlled interfaces, and AI audio applications. 🎤🌪️🧠
