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

Hello All Again,

I am not sure if this is the correct place to post about bugs for r128gain but I am sure someone will let me know. Anyway, in my last post I wasn't sure if I was running the program correctly, but it appears that I am. After doing a few tests with r128gain this is what I have found.

1. The program strips artwork, as was mentioned in an earllier post. Not a big deal if you are only tagging a few albums, but kind of a big deal when I want to do 1.5 terrabyte.

2. The program runs nicely and recurses thru directories of only 44100 sample rate albums. Runs thru to the end, no problem.

3. The program will not recurse thru directories of 96000 sample rate albums and higher. It crashes immediatley and the window closes in an instant. So if there is a mix of 44100 and 96000 it won't run(on this machine anyway). Or even if only 96000 sample rate albums are in the directory it still crashes.

4. The program will tag 96000 sample rate albums if done seperatley one by one. Not a big deal if you are only tagging a few albums, but as mentioned above, kind of a problem if your doing a terabyte or more. I don't have that many of these 96000 sample rate albums but it will still take awhile to get them sorted doing it one by one.

I am using Ubuntu 12.10 64bit with the default settings using replaygain settings as shown on the homepage, I hope they are the best settings?? The program is really nice, I like it alot. Kudos to Mr. Belkin for this fine program. I just thought I would post my findings here for others that may be having similiar problems, and sorry if some of these problems have been mentioned before, I didn't see it.

Cheers,

Singtoh
