This change enables the use of two different adaptation speeds of the matched filter of the delay estimator of AEC3. One speed is used when no delay has been found, and one is used after a reliable delay has been found. The purpose is to use a slower adaptation speed to reduce the risk of divergence during double-talk without slowing down the search for the initial delay. The CL prepares for experimentation by adding field trials for controlling the two adaptation speeds.
