Comment 11 for bug 1261666

Please increase the importance further,
I think the demand for a thing like the webrtc echo cancellator is higher than you expect. I know a few people who stay with windows because of the noise-reduction in the realtek audio driver, which removes the crackling noise in teamspeak/skype they have in linux (see http://unix.stackexchange.com/questions/115433/microphone-static-background-noise-suppression-on-linux for a longer dicussion).
I compiled pulseaudio myself to check if that module would solve the problem ... and indeed, with that plugin the quality of my microfone input can be improved to the quality it has in windows with the realtek driver.
