Loudness normalization

Enable loudness normalization: Enable/Disable the Loudness Normalization feature.
If Loudness Normalization is enabled, set a loudness unit to normalize the loudness to a target level.  For example, when the reference normalize level is set at -14.00 LUFS, if a program is analyzed to be -10.00 LUFS, the level would be lower by 4 dB to match the target loudness of -14.00 LUFS.
