VIDEO CONFERENCING

VCON Selects Andrea Electronics' Technology For Integration Into VCON's Conference Bridge

Andrea Electronics’ DSDA®, DFTA™ and Echostop™ technologies, developed by Lamar Signal Processing, Ltd., a wholly owned subsidiary of Andrea Electronics, bring the benefit of enhanced voice input to tele/videoconferencing systems by enabling clear audio communication in a hands-free, multi-conferencing environment. The technologies and digital algorithms allow the microphone to center its sensitivity in one focused direction, while reducing noise from all other sources. Benefits include lower reflection/distortion levels and improved sound quality plus advanced echo cancellation features, resulting in superior microphone/system performance. Patent-pending DFTA™ technology takes tele/videoconferencing to the next level of flexibility and control. DFTA’s proprietary algorithms are able to detect the presence of a voice and provide its direction to steer a videoconferencing system’s camera. Another innovative feature of DFTA technology is the presence of an echo-canceling algorithm to eliminate feedback of the audio system loudspeaker. EchoStop allows for true full duplex communication over the conferencing system, even when the system is used in large spatial environments that may be vulnerable to long reverberation times. The algorithm’s unique multi-band processing and seamless residual echo suppression capabilities provide clear communication, even in highly reverberant environments. EchoStop also incorporates noise reduction algorithms to reduce the background noise of both the input (microphone) and the output (loudspeaker), thus preventing the accumulation of interfering noise over multi-point conferencing systems.
