How about using SoX to transcode with a LADSPA plugin. There is one that is described like this: Matrix Spatialiser (matrixSpatialiser, 1422) A simple spatializer that lets you control the width of a stereo signal. We convert it into a MS (mid/side) signal, manipulate the gain coefficients with a constant-power panning function, and reconvert to left/right stereo. mid = (i_left + i_right) / 2 side = (i_left - i_right) / 2 width = (-pi/4)..0..(pi/4) o_left = mid * cos(width + pi/4) o_right = side * sin(width + pi/4) shifted by pi/4, so that 0 is neutral. Width 0 is neutral (unmodified signal) + 128 is side only (=very wide) - 128 is mid only (=mono)
