flactag - A tagger for whole album FLACs using data from the MusicBrainz service
[options] flacfile [ flacfile ] [ flacfile ]
basename [ /path/to/cdrom ]
basename numtracks [ /path/to/cdrom ]
IMPORTANT: I think I found a bug in cueconvert which means that
any FLAC files generated from CDs that used INDEX marks to separate tracks
that didn’t have any pre-gap would generate invalid disc IDs. I would
urge you to use the checkflac script provided to compare any
disks you may have ripped with their FLAC files to ensure that the discids
match correctly. Included in this release is a SED script which will massage
the TOC file of a CD to work around this problem. Unfortunately, the only way
to recover from this is to re-rip the CD.
To rip a CD to flac, simply enter ripflac <basename> (where basename is
used as the base name of the FLAC file you will be creating. The CD in the
drive will be ripped, and a FLAC file created containing an embedded CUE
sheet. ripflac takes an optional final parameter for the path to the CD drive,
which defaults to /dev/cdrom.
If the original CD contains data tracks, then the FLAC conversion will fail.
Should this happen, enter ripdataflac <basename> <range> (where
basename is the same one specified in the first rip attempt, and range is the
range of tracks to rip (e.g. if the CD has 13 tracks, where track 13 is the
data track, then the range would be 1-12). ripdataflac takes an optional final
parameter for the path to the CD drive, which defaults to /dev/cdrom.
During the ripping of the data CD, you will be provided with the CUE sheet in an
editor. You should delete the data track from this CUE sheet file and save it
(I will try to automate this process at some point).
Both these scripts will compare the calculated discid of the FLAC file with the
discid of the CD in the drive. If they do not match, a warning will be issued.

This option implies --check. If the

will be written to the file.
If --write is specified then tags will be
written even if they appear to match those already in the file.

is executed without any options, it will interactively process
all FLAC files given as arguments.
If the flactag utility does not find information for your CD, a URL will be
provided to submit information for it. Often the MusicBrainz server will have
information about the tracks and artist, but cannot match this up to your CD.
In these circumstances, it is simply a matter of 'associating\' your
CD’s DiskID with the correct album data on the MusicBrainz server. In
other instances, you may be required to enter the track and album information
into the MusicBrainz service. Once you have entered this information, you can
re-run flactag, and the data should be downloaded from the MusicBrainz server.
If the flactag utility finds information for your CD at the musicbrainz server,
the application’s main window will be shown.
This contains three main areas:
•The 'Albums' window. This will
contain a list of albums that match the DiskID for your FLAC file.
•The 'Tracks' window. This
contains a list of all the tracks on the currently selected album.
•The 'Tags' window. At startup,
this will contain a list of the tags currently found in your FLAC file. If
there are no tags present, then an empty set appropriate for the album will be
displayed. If you make changes to these tags, an asterisk ('*') will be
displayed to indicate that this information has been changed.
The currently active window will be highlighted by the border and window title
changing colour. To switch between the three windows, press the TAB
key. To scroll around the active window, use the cursor UP
keys (to scroll one line at a time) or the PAGE UP
and PAGE DOWN
keys (to scroll half a page at a time). Scrolling in the
window will update the information in the 'Tracks'
Once the appropriate album has been selected, pressing c

tags for that album into the 'Tags'
window. These tags can then be

will rename the file based on the settings in the
configuration file (~/.flactag - this file is created automatically the first
time you run flactag

actually written to the file, so should generally be performed after the new
tags have been written. This option will be unavailable if the filename and
location are already correct.
will move to the next file specified on the command line. If
all files have been processed, the application will exit.
The following configuration file (~/.flactag) entries affect file renaming:
•BasePath - This is the
root directory of where your music files should be stored. (e.g.
•SingleDiskFileName - This
template is used to rename disks that are not part of a multi-disk set.
•MultiDiskFileName - This
template is used to rename disks that are part of a multi-disk set.
The permissions to be set on any directory that is created (e.g. 0755).
•CreateCuesheetAfterRename - If
set to true, flactag will generate a cuesheet file to accompany the renamed
The FileName templates can accept the following parameters:
•%A - This will be replaced with
the artist name
•%S - This will be replaced with
the artist sort name
•%T - This will be replaced with
the album title
•%D - This will be replaced with
the disk number
•%Y - This will be replaced with
•%G - This will be replaced with
•%1 - This will be replaced with
the first character of the artist sort name
•%E - This will be replaced by
the appropriate filename extension (flac or cue)
If any item is used but does not have a value, then it will be stored as (for
example) NOGENRE (if the genre tag is empty).
To use a different MusicBrainz server (for example if you have a local mirror)
you can set the Server
parameters in the configuration
•Once changes are written to the FLAC
file, there is no way of reverting back to the original tags.
