Normalising audio with sox : Learnosity Blog:



  --norm[=dB-level]

              Automatically invoke the gain effect to guard against clipping and to normalise the audio. E.g.

                 sox --norm infile -b 16 outfile rate 44100 dither -s

              is shorthand for

                 sox infile -b 16 outfile gain -h rate 44100 gain -nh dither -s

              Optionally, the audio can be normalized to a given level (usually) below 0 dBFS:

                 sox --norm=-3 infile outfile



              See also -V, -G, and the gain effect.
