I am using the compand effect and getting a lot of clipping. Does the -G and norm options apply to the input? 
How do I normalize the output and prevent clipping?


sox -G --norm=-3 alien.wav alienout.wav. compand  0.3,1 -90,-90,-70,-70,-60,-20,0,0 -5 0 0.2
sox WARN compand: compand clipped 46934 samples; decrease volume?
