I mean sort of feedback killer? It will not. The echo cancellation module is meant for things like voip calls. For example, if you're using speakers and a mic, whatever the other end says goes back through the mic, and they will be hear themselves after a short gap. That's the echo we're trying to cancel. So the goal is for the *far end* to not hear echo. It will not make a difference locally. Cheers, Arun
