Key Features & Technical Advantages
Key Features & Technical Advantages of 8-array directional pickup microphone module
Utilizing an optimized 8-microphone array alongside sophisticated Beamforming technology, the module establishes a focused 60° directional pickup zone.
Automatic gain technology
Within a range of 3 meters, the volume will automatically increase or decrease based on the distance and volume of the speaker, ensuring clear and comfortable sound.
Automatic Echo Cancellation (AEC)
On the premise of ensuring smooth and comfortable communication, eliminate the sound played by the speaker to make the call smooth and comfortable
Noise Suppression (NS)
Filters out steady and non-steady background noises (such as HVAC systems, fan noise, and motor hum).
Voice Enhancement
Enhances vocal frequency bands to boost speech clarity and significantly improve Automatic Speech Recognition (ASR) accuracy.
