Bypassing residual echo suppression module.

Started by neelufar.2005 October 17, 2007
Hello All,

I am searching for the method to detect if there is residual echo or not
in the output of acoustic echo cancellation. So that if the acoustic echo
cancellation does 100% cancellation of echo then there is no need of using
residual echo suppression module after the acoustic echo cancellation
module. Can any one help regarding bypassing the residula echo suppression
module.
Thanks in advance.

Regards,
Neelufar.

There is always some residual echo. The question is how much of echo.

100% - never. 90% - could be.
