NAME

       SReview::Normalizer - normalize the audio of a video asset.

SYNOPSIS

         SReview::Normalizer->new(input => SReview::Video->new(...), output => SReview::Video->new(...))->run();

DESCRIPTION

       "SReview::Normalizer" is a class to normalize the audio of a given SReview::Video asset,
       using bs1770gain at its default settings.

       It looks at the "command_tune" configuration parameter to decide whether to pass the
       "--suffix" option to bs1770gain: if the installed version of "bs1770gain" is at 0.5 or
       below, set the "bs1770gain" key of "command_tune" to 0.5 to remove the "--suffix"
       parameter from the command line (which is required for 0.6 or above, but not supported by
       0.5 or below).
