[pulseaudio-discuss] Microphone noise cancelation

[Sébastien Escudier]

Hi,

I have an embedded audio chipset [1] with too much noise on my microphone 
input and it is unusable as is.
Could there be an option to remove this noise ?
I know it is possible because windows has such option wich works great.
I tried pulseaudio module-echo-cancel but it did not improve a lot.
To illustrate what kind of noise I am talking about you can find a short 
recording here :

Best regards,
Sébastien.
