Microphone - static background noise suppression
- by user1873947
My soundcard is Realtek ALC 892. On Windows 7 I use official Realtek drivers, on Linux I use PulseAudio (on Ubuntu 13.10). On both Windows and Linux, when I enable microphone boost +30db (required because my microphone is quiet), I get very annoying and loud background noise (I also confirmed the background noise with Audacity on both systems).
However, Windows Realtek drivers have noise suppression option which works (after enabling it, Audacity shows no background noise and my ears also confirm that there is no background noise).
My question is how can I enable background noise suppression in ALSA/PulseAudio? Is there any module I can install or maybe there is a setting for it that can be enabled in config file?
I can't find solution for it and this is the only thing that prevents me from switching to Linux completely - as I talk using microphone a lot and on Windows the Realtek software removes the background noise completely and PulseAudio doesn't remove it, which means the recorded voice on Linux is very bad.
I know I could buy better soundcard and microphone, but as I said, Windows Realtek drivers remove the noise on software level in real time (ie no noise when talking on TeamSpeak3/Steam/whatever voip programme) so I hope that there is such option on Linux as well.
Thanks in advance!
