Developed by Lamar Signal Processing Ltd., a wholly owned subsidiary of Andrea Electronics Corporation, patent-pending Directional Finding and Tracking Array (DFTA ) technology utilizes an volumetric array of microphones, unique software algorithms and digital signal processing (DSP) to detect the presence of a voice, determine its direction and follow and track it when it moves
Developed by Lamar Signal Processing Ltd., a wholly owned subsidiary of Andrea Electronics Corporation, patent-pending Directional Finding and Tracking Array (DFTA ) technology utilizes an volumetric array of microphones, unique software algorithms and digital signal processing (DSP) to detect the presence of a voice, determine its direction and follow and track it when it moves.
In a videoconferencing setting, these unique speech detection algorithms provide direction to a videoconferencing system, allowing the system to focus on the voice. The array/DSP unit, which detects a voice, finds its direction and transmits the direction to rotate and control the videoconferencing camera. The DFTA technology also steers a directional microphone beam towards the voice and also recognizes the reference output from the audio speaker source, activating an echo-canceling algorithm to eliminate acoustic feedback of the loud speaker sound through the audio system.
This highly accurate and intelligent microphone beamforming solution serves to dramatically reduce background noise, recognizing and subtracting out extraneous noise signals in real time and transmitting only a clear, desired audio source. DFTA offers superior acoustic echo cancellation, complete audio clarity and highly accurate tracking performance for a more natural sounding full duplex audio/videoconferencing experience.
