SYSTEM AND METHOD FOR CANCELING ACOUSTIC ECHOES IN AUDIO-CONFERENCE COMMUNICATION SYSTEMS

摘要

Various embodiments of the present invention are directed to a frequency-domain coder/decoder (802) for an audio-conference communication system that includes acoustic-echo-cancellation functionality. In one embodiment of the present invention, an acoustic echo canceller (812) is integrated into the frequency-domain coder/decoder (802) and ameliorates or removes acoustic echoes from audio signals that have been transformed to the frequency domain and divided into subbands by the frequency-domain coder/decoder (802).
