FLAC1170: a ITU BS.1770 loudness scanner for FLAC Options

[pbelkner]

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:

• Download: https://sourceforge.net/projects/r128gain/files/flac1770/
  
• Download v0.1: https://sourceforge.net/projects/r128gain/f...s/flac1770/0.1/

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

Thanks for the software.

Shouldn't the / be \?

Also, why is the ReplayGain calculated by flac1770 much different than the one calculated by foobar2000?

It depends ...

It's true for the CMD window aka DOS-box on Windows. But mostly I'm using a MSyS shell on Windows or Linux at all ...

You're right. ReplayGain is different from ITU BS.1770: it's not only a matter of units, I have to transform the values as well.
