Abstract
A system and method, automatically adaptable for use on multiple platforms, configured to reduce echoes heard by an end user of a remote communication device is provided. The system is configured to transmit communication from the remote communication device to a speaker, and to pick up communication from the microphone to the remote communication device. The system and method is directed towards emitting a test signal and processing the signal so as to calculate a phase shift to be applied to an outgoing auditory signal. The calculated phase shift is configured to cancel the test signal.
