When we start work on the next major release of DROffline MkII, we would like to be able to include comprehensive DRi tagging for FLAC and ALAC as well as LPCM like AIFF and WAV. For that, we’d need Roon’s help.
BTW, musicjunkie917’s comment is true in that LRA is not a dynamic range measurement. LRA or Loudness Range is the most commonly used metric in the whole 1770/R 128 suite of measurements. In fact, nothing in the R 128 spec was not designed to measure subjective loudness. Unlike DRi, R 128 isn’t well suited to that task.
