Method for seamless noise suppression on wideband to narrowband cell switching
Abstract:
A method for seamless noise suppression on wideband to narrowband cell switching is described. In one embodiment the method includes applying noise suppression to a telephone signal using a first noise suppressor while operating a telephone in a first operating mode, the first noise suppressor generating an estimate of a noise components of the telephone signal; switching the telephone from the first operating mode to a second operating mode; providing the estimate of the noise component as an input to a second noise suppressor different from the first noise suppressor, when the switching step is performed; and applying noise suppression to the telephone signal using the second noise suppressor by using the estimate of the noise component provided by the first noise suppressor when the switching step is performed.
