Key Technical Advantages:

• DNN-Based Smart Noise Cancellation: Unlike traditional filters, our DNN algorithm specifically identifies human vocal patterns, achieving a noise suppression depth of ⩾ 35dB by effectively stripping away non-human interference.

• Precision AI Beamforming: Utilizing 4-mic array synergy, this module generates a highly focused beam pattern. It offers superior spatial selectivity compared to conventional tech, supporting Omnidirectional, Bi-directional, and Uni-directional modes.

• Adjustable “Beam Area”: The pickup angle is customizable. Within the Beam Area, voices are enhanced and purified via AI-Noise Cancellation; in the Non-Beam Area, interfering speech is blocked. The transition boundary is meticulously controlled within a 5°–10° deviation.

• Advanced Acoustic Echo Cancellation (AEC): High-grade AEC prevents far-end feedback, ensuring a smooth, echo-free full-duplex communication experience.

• Plug-and-Play Integration: Features driver-free USB Audio Device support alongside analog interfaces, making it compatible with Android, Linux (2.6.24+), and Windows VISTA/7/8/10/11
