I don't know enough about CODECS to know the right answer (thus must post here), but right now the OpenGD77 source basically includes an bit of assembly language to call some binary code lifted out of the vendor's original firmware. My interest is to drop in a different CODEC, but I don't know enough about them to understand exactly what needs to be done.
