Hi,

Please is there a way to add a fixed DC offset to one channel stream in alsa config (.asoundrc)?

We are playing with single-ended -> virtual balanced setup ( http://www.diyaudio.com/forums/pc-based/326747-virtual-balanced-regular-soun... ) using the route plugin. The setup works surprisingly nice.

Unless one of the input channel AD convertors has a DC offset which ruins the subtracted signal. It is easy to measure the offset.

Such as e.g.

type route ttable { 0.0= 0.49 + 0.001 0.1= -0.49 }

Thanks a lot for any suggestions.

Best regards,

Pavel.
