NAME¶
cue2toc - convert CUE to TOC format
SYNOPSIS¶
cue2toc [
-dhqv] [
-o tocfile] [
cuefile]
DESCRIPTION¶
Cue2toc converts
cuefile from CUE to TOC format and writes the
result to
tocfile. If either
cuefile or
tocfile is
omitted or a single dash "-"
cue2toc reads from standard
input and writes to standard ouput respectively.
CUE files are text files describing the layout of a CD-Rom and typically carry
the extension ".cue".
Cdrdao is a CD-burning application which has its own native TOC format to
describe the disc layout. Although cdrdao has direct support for reading CUE
files, it is currently limited to data tracks only. So
cue2toc's main
usefulness lies in converting CUE files containing audio tracks.
CUE files for audio discs often come with data files in compressed audio formats
like MP3 or Ogg Vorbis. To burn such a disc with cdrdao these files must be
converted to WAVE or raw format.
Cue2toc can do this automatically if
configured properly (see section
CONFIGURATION below for more
information).
Cue2toc normally displays warning messages for unsupported commands and
constructs as well as for each data file converted. The
-q option
disables these messages.
OPTIONS¶
- -d
- print debugging information
- -h
- print a short help message
- -o tocfile
- write result to tocfile instead of standard ouput
- -q
- quiet mode; do not print warnings
- -v
- display version information
What follows is a description of the CUE format expected by
cue2toc. For
information about the TOC format please consult the
cdrdao(1) manual
page.
CUE files consist of commands and their arguments which must be separated from
each other by any number of whitespace characters. Space, horizontal
tabulator, newline and carriage return are recognized as whitespace characters
except inside strings surrounded by double quotes, where they are part of the
string. Commands are not case sensitive. CD-Text data can be at most 80
characters per item.
Timecode values are accepted in the forms "X:X:X", "X:X" and
"X" where each "X" must consist of at most two digits and
may be zero padded to the left. They are interpreted as "M:S:F",
"S:F" and "F" respectively where "M" means
"minutes" and must be in the range 0 <= M <= 99, "S"
means "seconds" and must be in the range 0 <= S <= 59, and
"F" means "frames" and must be in the range 0 <= F
<= 74.
CUE files are logically divided into a global section and one to 99 track
sections. Inside these sections the following commands are allowed:
Global Section¶
REM anything_to_newline
CATALOG string
CDTEXTFILE string
TITLE string
PERFORMER string
SONGWRITER string
FILE string
BINARY|
MOTOROLA|
AIFF|
WAVE|
MP3
- REM
- Optional. Introduces a comment. Anything from there on up to and including
the next newline character is ignored. Comments can appear anywhere in the
file but not between a command and its arguments.
- CATALOG
- Optional. The Media Catalog Number of the disc. Must be exactly 13
characters.
- CDTEXTFILE
- Optional. Specifies an external file containing CD-Text data. Ignored.
- TITLE
- Optional. The CD-Text title of the disc.
- PERFORMER
- Optional. The CD-Text performer of the disc.
- SONGWRITER
- Optional. The CD-Text songwriter of the disc.
- FILE
- Required. The name and type of the file to be used for all following
tracks. The string contains the name of the file followed by one of
BINARY, MOTOROLA, AIFF, WAVE or MP3. As
far as cue2toc is concerned the type of the file is effectively
ignored. Nonetheless MOTOROLA, AIFF and MP3 cause
printing of a warning message since these file types can not be used
directly with cdrdao.
The first appearance of a
TRACK command causes leaving of the global
section and entering the track section.
Track Section¶
TRACK number mode
REM anything_to_newline
FLAGS [
DCP] [
4CH] [
PRE] [
SCMS]
ISRC string
TITLE string
PERFORMER string
SONGWRITER string
PREGAP timecode
INDEX number timecode
POSTGAP timecode
FILE string
BINARY|
MOTOROLA|
AIFF|
WAVE|
MP3
- TRACK
- Required. Starts a new track definition. The number is ignored. The
mode must be one of AUDIO, MODE1/2048,
MODE1/2352, MODE2/2336 or MODE2/2352.
- FLAGS
- Optional. Defines the flags for this track. Must be followed by one or
more of the following commands: DCP (digital copy permitted),
4CH (four channel audio), PRE (pre-emphasis enabled) and
SCMS (serial copy management system). SCMS is ignored
because there is no corresponding option in the TOC format.
- ISRC
- Optional. The International Standard Recording Code for this track. Must
be exactly 12 characters long.
- TITLE
- Optional. The CD-Text title of this track.
- PERFORMER
- Optional. The CD-Text performer of this track.
- SONWRITER
- Optional. The CD-Text songwriter of this track.
- PREGAP
- Optional. The length of the track pregap to be filled with zero data.
Mutually exclusive with INDEX 0.
- POSTGAP
- Optional. The length of the track postgap to be filled with zero data.
- INDEX
- Optional. The number must be in the range 0 <= number
<= 99. Index number 1 specifies the start of the track. Index number 0
is the start of the track pregap filled with data from the file, i.e. the
difference between index 0 and index 1 is the length of the pregap. Index
0 is mutually exclusive with PREGAP. Index numbers greater than 1
specify subindexes for this track and must be sequential.
- FILE
- Optional in track section. The syntax is the same as described above and
if it appears inside a track specification it takes effect on the next
TRACK command.
CONFIGURATION¶
Cue2toc can be configured by specifying options in the file ~/.cue2tocrc.
The syntax of this file and allowed configuration options follow.
Comments are introduced by the hash character '#' and extend to the end of the
line. Configuration options take the form
OPTION = value
The value must be quoted if it contains whitespace characters. To include a
double quote character in a quoted string, precede it with a backslash. Option
values can either be of boolean type or string type. For boolean types any one
of "yes", "y", "true" or "1" means
true and anything else means false. The "default value" in
the descriptions of the individual options below is the value assumed by
cue2toc in the absence of the option from the configuration file.
- CONVERTER = ext_from ext_to command
- This option takes three string arguments and specifies a converter for
files with the extension ext_from. They are converted by the given command
and the extension is replaced with ext_to in the TOC file. When the
command is run the environment will contain the two variables C2T_FROM and
C2T_TO which contain the original and new file name respectively. For
example
CONVERTER = .mp3 .wav
"lame --decode \"$C2T_FROM\" \"$C2T_TO\""
will convert all MP3 files to WAVE format using lame. It is a good idea to
quote the varibles $C2T_FROM and $C2T_TO because they could contain
whitespace or other funny characters with a special meaning to the shell.
This option can be specified multiple times and each file is checked against
the list of converters to see if it matches any of them. If multiple
converters match a given file only the first match is used.
If a file with the name that results from replacing ext_from with ext_to
already exists, the conversion command will not be executed.
This option has no default value.
- CONVERT = boolean
- This option enables or disables the conversion of data files as described
above for the CONVERTER option. If this option is false, no conversion
will take place. The default value is "yes".
- QUIET = boolean
- If this option is true it has the same effect as if cue2toc was
invoked with the -q command line option. The default value is
"no".
- CDTEXT = boolean
- This option enables or disables the writing of CD-Text data to the TOC
file if it is present in the CUE file. The default value is
"yes".
LIMITATIONS¶
The command
CDTEXTFILE and the flag
SCMS have no equivalent in the
TOC format and are ignored.
CUE files containing data tracks which specify a starting time greater than zero
cannot be converted by
cue2toc because the TOC format does not provide
a way to specify a starting time at all for data tracks. However if the CUE
file does not contain any audio tracks you can try to use the CUE file
directly with cdrdao.
FILES¶
- ~/.cue2tocrc
- The configuration file. The format of this file is described in the
section CONFIGURATION above.

BUGS¶
Since
cue2toc's definition of the CUE format is entirely based on a
number of different CUE files the author came across there is a very high
probability that it will not work correctly with all the other CUE files you
might encounter. If this is the case for you please send the problematic CUE
file along with the version number of
cue2toc to
<dermatsch@gmx.de>.
