Sure thing, and thanks again for your hard work on this program!!

Cheers,

FLAC1770 v0.2.0 released

What's new?

• Test case #6 passed.
• Unit for absolute loudness in ReplayGain mode is dB.
• Provided a "--quiet" option.

Binaries are available for Win32, Linux, and Linux64:

• Download: https://sourceforge.net/projects/r128gain/files/flac1770/
  
• Download v0.2: https://sourceforge.net/projects/r128gain/f...s/flac1770/0.2/

CODE

$ flac1770
FLAC1770 v0.2.0, 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).
  --quiet: suppress writing to stdout (off).
  --true-peak=fast|medium|best|off: determine inter-sample peaks (off).

[*]Unit for absolute loudness is dB.

Thanks!

Edit: How to prevent reporting of positive album peaks like "REPLAYGAIN_ALBUM_PEAK 1.00003052" ? --true-peak=off is not it.

How to prevent reporting of positive album peaks like "REPLAYGAIN_ALBUM_PEAK 1.00003052" ? --true-peak=off is not it.

By using v0.2.1

Download: http://sourceforge.net/projects/r128gain/files/flac1770/0.2/

This version takes into account that the largest negative integer is by 1 larger then the largest positive integer.

[Wombat]

By using v0.2.1

Indeed!

As a casual follower of these threads, is there a difference between ITU BS.1770 and the R128GAIN algorithm discussed in the other thread? If not, what's the difference between this tool and the one offered in the R128GAIN thread?

"flac1770" is meant to be a lightweight version of "r128gain" specialized to FLAC working around some specufic FFmpeg and SoX related issues brought up in the r128gain thread:

• avoids using FFmpeg
• avoids using SoX (the SoX resampler crashes on huge files, will be fixed with the next release thanks to a SoX patch provided by MrMod)
• is based on "libFLAC"
• should preserve FLAC artwork
• uses Secret Rabbit Code for up-sampling
• has "true peak" switched off by default
• doesn't provide "loudness range" computation (if provided in the future it will be switched off by default)
• no unicode support on win32

Both, "r128gain" and "flac1770" use the ITU BS.1770 loudness algorithm as provided by "lib1770".
