Hey Ken! If not sox, then ecasound: ecasound -f:bit_depth,2,samplerate -a:1 -i stereo1.wav -a:2 -i stereo2.wav -f:bit_depth,4,samplerate -chmove:1,3 -chmove:2,4 -a:all -o quatro.wav Should do it, but didn't test it. In any case, it is possible to perform that action. Besdies that, there's of course csound.
