Just some notes:

sox has compression. I am toying with this one, basically lifted from the man page. At least it looks a bit complex:

sox audio-in.wav soxied.wav gain -28 mcompand "0.005,0.1 -47,-60,-34,-55,-17,-33,0,-10" 100 "0.003,0.05 -47,-60,-34,-55,-17,-33,0,-10" 400 "0.000625,0.0125 -47,-60,-34,-50,-15,-33,0,-10" 1600 "0.0001,0.025 -47,-60,-34,-50,-31,-31,-0,-30" 6400 "0,0.025 -38,-60,-28,-28,-0,-25" gain 15 highpass 22 highpass 22 sinc -n 255 -b 16 -17500  gain 9 lowpass -1 17801
