Standard Options:

-o <folder>   destination folder for the output file(s).
-nts <n>      set noise_threshold_shift to n dB (-48.0dB<=n<=+12.0dB);
              (-ve values reduce bits to remove, +ve values increase).
-snr <n>      set minimum average signal to added noise ratio to n dB;
              (0.0dB<=n<=48.0dB) Increasing value reduces bits to remove.
-force        forcibly over-write output file if it exists; default=off.
