The present invention is embodied in a computer-readable program in a computer-readable medium for upgrading a video conference system, the computer-readable program comprising acoustic echo canceling control software having an application programming interface. The acoustic echo canceling control software is implemented on a computer system that operates the video conference system and macros are configured to couple the acoustic echo canceling control software to hardware components of the video conference system and to interface with the application programming interface. The macros are user configurable for providing real time adjustments of echo canceling runtime parameters of the hardware components during a video conference session.

Integrating acoustic echo cancellation as a subsystem into an existing videoconference and telepresence system

A system including at least one system microphone, a processor connected to computer readable memory and the at least one system microphone, a measurement microphone connected to the processor, at least one audio speaker, a signal generator connected to the processor and configured to produce signals from the at least one audio speaker for both the measurement microphone and the at least one system microphone to measure the response of the at least one audio speaker, and a device manager application executable from the computer readable memory and configured to perform the steps of calibrating the at least one audio speaker with the measurement microphone using the signals of the signal generator based on the response of the at least one audio speaker thereby creating at least one calibrated audio speaker and calibrating the at least one system microphone with the at least one calibrated audio speaker using the signals of the signal generator.

Calibrating at least one system microphone

An apparatus projects at least one color of light which is attenuated.
