+    If the measured loudness from the first pass is lower than the target loudness then normalization pass will be skipped for the measured audio source.

 - `--dual-mono`: Treat mono input files as "dual-mono".
 
     If a mono file is intended for playback on a stereo system, its EBU R128 measurement will be perceptually incorrect. If set, this option will compensate for this effect. Multi-channel input files are not affected by this option.
