NAME

       collectiongain - large scale Replay Gain calculating tool

SYNOPSIS

       collectiongain [options] music_dir
       collectiongain --help
       collectiongain --version

DESCRIPTION

       collectiongain  is a script calculating the Replay Gain values of a large set of music files inside music_dir. Each audio file will be rec-
       tified against the other files of the same album, which are identified using the file tags.

OPTIONS

       --version
	      Display the version of the software.

       -h, --help
	      Display a short summary of the available options.

       -f, --force
	      Recalculate Replay Gain even if the file already contains gain information.

       -d, --dry-run
	      Don't actually modify any files.

       -r REF, --reference-loudness=REF
	      Set the reference loudness to REF dB (default: 89 dB)

       --mp3-format=MP3_FORMAT
		 Choose the Replay Gain data format for MP3 files.  Since there is no commonly accepted standard for Replay Gain in MP3 files, you
		 need to choose.  Possible formats are :

	      o ql (used by Quod Libet). This is the default value.

	      o fb2k (read and written by foobar2000, also understood by Quod Libet)

	      o mp3gain (tags as written by the mp3gain program; this doesn't modify the MP3 audio data as said program does).

       --ignore-cache
	      Don't trust implicit assumptions about what was already done, instead check all files for Replay Gain data explicitly.
