SoX Filter Phase Setting

RE: SoX Filter Phase Setting in 3.5.2 Win10, is it right to assume that if the slider is set to zero 0 that a minimum phase filter is being used? Or should the slider be set to 100 for a minimum phase filter? I am trying to achieve minimum pre-ringing. Thanks!

Hello @JotBF2, you are right, as it is mentioned in brackets. (Min on the left is for 0 and Linear on the right is for 100).
