Converting VST to Sox mcompand

Hello,


I'm trying to convert a multiband VST to Sox mcompand.

I'm pretty sure I did it correctly, but somewhere there must be 
something different as my Sox results are extremely distorted.

I just don't see where I did something wrong. Does anybody do?

This is a screenshot of the 4 different bands of the VST:

And this is my Sox mcompand approach to achieve the same:

play orig.wav gain -n -6 mcompand "0.0,0.0 -16.5,-1.2 -5.3" 90 "0.0,0.0 
-12.5,-0.6 8.0" 700 "0.0,0.0 -13.2,-0.6 9.7" 4800 "0.0,0.0 -13.8,-1.8 4.7"


Does anybody see where I went wrong?


Thank you very much!
