1. Multi Functional: Mic module integrates a variety of algorithm technologies in one, which can quickly realize the intelligent transformation of products, support sound and video calls, recording and forensics, voice recognition, menu navigation and many other functions.
2. 1.5m Directional Pickup: Mini microphone module supports dual microphone linear microphone arrays with embedded automatic gain control, noise reduction, de reverberation and other algorithms, target directional voice enhancement and suppression of surrounding noise.
3. Aftersound Cancellation: Microphone board uses the microphone arrays null domain filtering characteristics to form a directional pickup beam and suppress noise outside the beam to ensure high recording quality.
4. De Reverberation: Mic modules de reverberation method based on multi channel linear adaptive de reverberation algorithm (MCLP) directly initializes the target signal covariance with the array acquisition signal to further enhance the speech de reverberation performance.
5. Debug Free: Microphone module requires no driver, plug and play, supports for Windows and foroperating systems, and is widely used in financial, for smart tv, conference screen, pickups and other terminal devices.
