FLAC1770 is a ITU BS.1770 loudness scanner and tagger for FLAC. For tagging it should do exactly tha same as "metaflac".

Binaries are available for Win32, Linux, and Linux64:
CODE
$ flac1770
FLAC1170 v0.1.0, a ITU BS.1770 loudness scanner for FLAC.

Usage: flac1770 [options] <files>

Options:
  --help: dispaly this usage information and exit.
  --version: dispaly version information and exit.
  --tag: write replay gain tags to the input files (off).
  --r128: use EBU R128 compliant presets (default).
  --a85: use ATSC A/85 compliant presets.
  --rg: use ReplayGain compatible presets.
  --reference=<float>: set reference loudness (-23.0).
  --gate=<float>: set BS.1770 gate (-10.0).
  --partition=<int>: set BS.1770 partition (4).
  --unit=LU|LK|dB: use the respective loudness unit (LU).
  --progress=on|off: display progress percentage (on).
  --true-peak=fast|medium|best|off: determine inter-sample peaks (off).

Some examples:
  • Analyze some individual tracks:
    CODE
    flac1770 track1.flac track2.flac track3.flac


  • Analyze some individual tracks and write RG tags to them:
    CODE
    flac1770 --tag track1.flac track2.flac track3.flac


  • Analyze all tracks from a folder:
    CODE
    flac1770 dir/*.flac


  • Analyze all tracks from a folder and write RG tags to them:
    CODE
    flac1770 --tag dir/*.flac


  • Analyze all tracks from a folder and write RG tags to them, compatible with standard ReplayGain:
    CODE
    flac1770 --rg --tag dir/*.flac


  • Analyze all tracks from a folder, including inter-sample peak determination, and write RG tags to them, compatible with standard ReplayGain:
    CODE
    flac1770 --rg --true-peak=fast --tag dir/*.flac

I use loudness command from libebur128. Works great. Added advantage of that that it can handle vorbis and supposedly mp3. That uses -10 dB gate and 75% overlap AFAIK. I certainly did not find any issue against Quasi Audio and the EBU test vector.
