Thank you, Charles. But I need to remove DC offset in realtime, for example, when I make calls with Google Voice. So, is there a filter that can be connected with ALSA audio input and generates output with no DC offset? Thanks again. -- Tao On Sun, Nov 13, 2011 at 11:47 AM, Charles Cazabon < cha...@py...> wrote: > Chen Tao <pr...@gm...> wrote: > > > > My sound card generates severe DC offset in recorded audio signal.
