r128_*_gain: Relative OPUS-specific R128 gain, ReplayGain tags formatted as(+/-) (Decibel Adjustment x 256) dB.- Note that OPUS files also have a "header gain" within their format that is also applied, in which the R128 tags are applied on top of. This base gain is applied by the system media codec, not Auxio.
It is highly recommended to use rsgain to tag ReplayGain information, as Auxio's ReplayGain functionality intends to conform with that tool as close as possible.
