Abstract
We present an extremely simple and effective signal processing solution to the acoustic echo control problem. The approach is based on the concept of synchronous statistical adaptation of an acoustic echo canceler and a postfilter for residual echo suppression. The required convergence state of the echo canceler is estimated by a new statistical element of our system. Double talk detection is not required explicitly. The whole solution combines an excellent output signal quality with a high degree of elegance and simplicity.
