.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`SReview::Normalizer\*(C'\fR is a class to normalize the audio of
a given SReview::Video asset, using bs1770gain at its default settings.
.PP
It looks at the \f(CW\*(C`command_tune\*(C'\fR configuration parameter to decide
whether to pass the \f(CW\*(C`\-\-suffix\*(C'\fR option to bs1770gain: if the installed
version of \f(CW\*(C`bs1770gain\*(C'\fR is at 0.5 or below, set the \f(CW\*(C`bs1770gain\*(C'\fR key
of \f(CW\*(C`command_tune\*(C'\fR to 0.5 to remove the \f(CW\*(C`\-\-suffix\*(C'\fR parameter from the
command line (which is required for 0.6 or above, but not supported by
0.5 or below).
.SH "ATTRIBUTES"
