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

CUE FORMAT

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.
