Yes, the GSM Codec is mono but it will accept a stereo stream. I'm not sure
if it throws away the right channel or mixes it with the left.

I would base you splitter filter on the InfTee filter sample that is in the
DXSDK. The InfTee sample will make a duplicate output to each pin, you
should be able to modify it to send a selective data stream to each output.
