Key Technical Highlights
High-Density 8-Mic Matrix: Compared to standard 4-mic solutions, the 8-mic architecture delivers a narrower beam and stronger directivity, ensuring crystal-clear voice pickup within a 5-meter range.
180° Frontal Directionality: Optimized for users positioned in front of the device. It effectively mutes sound from the rear and sides, preventing false triggers and background noise interference.
Pro-Grade Acoustic Processing:
AEC (Acoustic Echo Cancellation): Essential for full-duplex communication in TVs and Soundbars.
NS (Noise Suppression): Advanced suppression of ambient noise and room reflections.
Beamforming (BF): Digitally focuses on the active speaker for enhanced signal quality.
Seamless System Integration: Supports standard digital interfaces (USB / I²S) and is fully compatible with mainstream voice platforms like XMOS, Android, and Windows.
