bs1770gain - lundness scanner and normalizer based on ITU-R BS.1770
bs1770gain [options] <file/dir> [<file/dir> ...]
BS1770GAIN is a loudness scanner compliant with ITU-R BS.1770 and its flavors EBU R128, ATSC A/85, and ReplayGain 2.0. It helps normalizing the loudness of audio and video files to the same level. See bs1770gain --help for experimental options. Command line arguments can appear in any order.
