Claim 11:
12. The apparatus of claim 11, wherein the controlling the at least one filter with different values of the at least one control parameter at different times further comprises:
controlling the first filter and second filter with different values of corresponding first and second respective control parameters that affect a rate of change of corresponding estimates of the coefficients of the acoustic channel, wherein a value of the first control parameter set for the first filter causes the estimates of the coefficients of the acoustic channel to change at a slower rate than a rate of change caused by a value of the second control parameter set for the second filter;
repeatedly estimating error cancellation performance of the first and second filters; and
updating, after the repeated estimation, the coefficients of the first or second filter estimated to have lower performance to be closer to the coefficients of the other of the first or second filter estimated to have higher performance.
