Relacart has recently launched an innovative ceiling microphone array – a solution integrating cutting-edge AI technology and advanced acoustic engineering, designed to deliver exceptional audio quality in any space. Our ceiling microphone is not just a technological innovation, but also the optimal audio solution for users in venues like conference rooms and classrooms. It ensures every word is accurately conveyed and no sound detail is overlooked.
Functional Features
Intelligent De-reverberation
Utilizes Deep Neural Networks (DNN) to eliminate echoes in reflective spaces (e.g., concert halls), enhancing Direct-to-Reverberant Ratio (DRR) for crystal-clear voice reproduction.
Dynamic Feedback Suppression
Integrated AI processor instantly identifies and suppresses narrowband feedback between speakers and microphones, ensuring stable, distortion-free audio.
Full-Duplex Acoustic Echo Cancellation
Eliminates echoes even during simultaneous speech, ideal for low Signal-to-Noise Ratio (SNR) environments without relying on mechanical design.
360° AI Noise Reduction
Removes background noise from both uplink and downlink communications while preserving voice clarity, enabling natural conversations in any setting.
