Add REPLAYGAIN_REFERENCE_LOUDNESS tag #13

Closed Moonbase59 closed 5 years ago

Moonbase59 commented 5 years ago

Could I persuade you to add a "REPLAYGAIN_REFERENCE_LOUDNESS" tag like "metaflac --add-replay-gain" does?

This might come in handy for mixed environments that support it (like mine, having old media tagged using "REPLAYGAIN_REFERENCE_LOUDNESS=89 dB" and newer media using a -23 LUFS target, like "REPLAYGAIN_REFERENCE_LOUDNESS=-23 LUFS").

Sorry, I will not implement that.

The RGv2 standard is backward compatible with the RGv1 spec, because the difference in loudness of both algorithms is compensated by the difference of reference loudness levels.

There is no need for such tags, and supporting them only adds confusion, and contributes to the proliferation of competing tags.
