How about a capacitor in the input?

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.

Yes, any audio-editing program (Audacity, Ardour, etc) will have a
function/filter for removing DC offset.
Hi,
My sound card generates severe DC offset in recorded audio signal. Is there
a way to remove this offset from audio input, for example, using a
equalizer or filter?
LADSPA plugins can be used to filter audio output, can they be used to
filter audio input?
Thank you!

Hi everybody,
I'd recently buy an UA101 USB Card, but the UA-101
linux driver doesn't seem to be really stable.
Please have a look at
