peah b1fc54d33e Corrected the delay agnostic AEC behavior during periods of silent farend signal. ... Added conditional updating of the statistics and the delay estimate so that updates are only done when the farend is non-stationary. The reason for this is that all the values that go into the updating of the statistics, and that in turn are also used to update the delay, are frozen when the farend signal is non-stationary. Therefore, when the farend signal is silent (stationary), the last estimates present before the silent (stationary) period began are used to continue to update the statistics. This is a problem as the updating is done in a manner that assumes that the estimates continue to be updated. This CL conditions the updating based on stationarity instead of silence as both are treated in the same manner in the delay agnostic AEC. This makes sense theoretically as the delay agnostic AEC operates on analyzing power deviations (in bands) from a slowly updated average power and therefore for a stationary signal will have no such deviations to base its analysis on.
