R128gain & metaflac

> it.
AFAICS the idea was to use R128 algorithm to calculate gain, but still
write ReplayGain tags (not some new R128 tags), with the reference level
that matches the reference level of the current RG algorithm.
For example, foobar2000 uses the following formula: "RG_gain = -18 - loudness_by_R128"
in accordance to the section 3.2.2.3 in http://www.dolby.com/uploadedFiles/Assets/US/Doc/Professional/AES128-Loudness-Normalization-Portable-Media-Players.pdf
And it seems that dBpoweramp uses it too ( http://forum.dbpoweramp.com/showthread.php?34044-ReplayGain-Utility-Codec-R4 ) -- "EBU...
