APPARATUS AND METHOD FOR ECHO SUPPRESSION

摘要

An input signal from the input source is received. An attenuation of an echo canceller filter is calculated using at least the input signal. A spectral component of a frequency band of an echo suppressor is adjusted to perform enhanced suppression using the calculated attenuation. A comfort noise factor is calculated using at least the input signal and the calculated attenuation. The comfort noise to the output of the echo suppressor is adjusted to obtain a modified input signal.
