REPLAYGAIN(1) rgain REPLAYGAIN(1)
NAME
replaygain - single file Replay Gain editor

replaygain --help
replaygain --version
DESCRIPTION
replaygain applies or displays Replay Gain information for audio files.
OPTIONS
--version
Display the version of the software.
-h, --help
Display a short documentation.

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).
--no-album
Don't write any album gain information.
--show Don't calculate anything, simply show Replay Gain information for the specified files. In this mode, all options other than
--mp3-format are ignored.
