bchunk - CD image format conversion from bin/cue to iso/cdr SYNOPSIS
bchunk [-v] [-p] [-r] [-w] [-s] <image.bin> <image.cue> <basename> DESCRIPTION
bchunk converts a CD image in a ".bin / .cue" format (sometimes ".raw / .cue") to a set of .iso and .cdr tracks. The bin/cue format is used by some non-Unix cd-writing software, but is not supported on most other cd-writing programs. image.bin is the raw cd image file. image.cue is the track index file containing track types and offsets. basename is used for the begin- ning part of the created track files. The produced .iso track contains an ISO file system, which can be mounted through a loop device on Linux systems, or written on a CD-R using cdrecord. The .cdr tracks are in the native CD audio format. They can be either written on a CD-R using cdrecord -audio, or con- verted to WAV (or any other sound format for that matter) using sox. The output type depends on the input type (data is just copied). If the input is in ISO format, the output will be. On the other hand, if the input is raw audio data, the output will be CDR or WAV (the latter if -w is given). It is advisable to edit the .cue file to either MODE2/2352/2048 or MODE2/2352/2324 depending on whether an ISO filesystem or a VCD is desired, respectively. The format itself does not contain this feature and in an ambiguous case it can only guess. OPTIONS
-v Makes binchunker print some more unnecessary messages, which should not be of interest for anyone. -w Makes binchunker write audio tracks in WAV format. -s Makes binchunker swap byte order in the samples of audio tracks. -p Makes binchunker go into PSX mode and truncate MODE2/2352 tracks to 2336 bytes at offset 0 instead of normal 2048 bytes at offset 24. Use this option if input is in PSX mode. -r Makes binchunker output MODE2/2352 tracks in raw format, from offset 0 for 2352 bytes. Good for MPEG/VCD. Use this option if input is in raw format. FILES
image.bin Raw CD image file image.cue TOC (Track index, Table Of Contents) file *.iso Tracks in ISO9660 CD filesystem format. Can be either written on a CD-R using cdrecord, or mounted (on Linux platforms at least) through a loop device ('mount track.iso /mnt/cdrom -o loop=/dev/loop0,blocksize=1024'). *.cdr Audio tracks in native CD audio format. They can be either written on a CD-R using 'cdrecord -audio', or converted to WAV (or any other sound format for that matter) using sox ('sox track.cdr track.wav'). *.wav Audio tracks in WAV format.

CUE2TOC(1) General Commands Manual CUE2TOC(1) NAME
cue2toc - convert CUE to TOC format SYNOPSIS
cue2toc [-hnqv] [-o tocfile] [-w wavefile] [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. Output of CD-Text data can be disabled with the -n option. CUE files often come with MP3 files but since cdrdao doesnt support decoding them on the fly they probably must be decoded by other means prior to writing the CD (e.g. using lame). For this reason you can specify a filename with the -w option to be used for all audio tracks instead of the one in the CUE file. Of course this is only really useful if all the tracks are based on the same file. This seems to be the case quite often however. Cue2toc normally displays warning messages for unsupported commands and constructs. The -q option disables these warnings. OPTIONS
-h print a short help message -n no CD-Text; disable output of CD-Text information -o tocfile write result to tocfile instead of standard ouput -q quiet mode; do not print warnings -v print version number -w wavefile use wavefile for all audio tracks 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. Nonethe- less 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 permit- ted), 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 pre- gap. Index 0 is mutually exclusive with PREGAP. Index numbers greater than 1 specify subindexes for this track and must be sequen- tial. 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. 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. EXAMPLE
Suppose we have the following CUE file "uwe.froehn.cue" describing an audio CD with CD-Text data: REM Example CUE file with audio tracks CATALOG 1234567890123 TITLE "Der Berg ruft" PERFORMER "Uwe Froehn" FILE "uwe.froehn.mp3" MP3 TRACK 01 AUDIO TITLE "Meine Mama ist die Beste" PERFORMER "Uwe Froehn" SONGWRITER "Hansi Klabuster" REM two seconds pregap filled with audio data INDEX 00 00:00:00 INDEX 01 00:02:00 REM subindexes INDEX 02 00:35:17 INDEX 03 01:12:44 TRACK 02 AUDIO TITLE "Hoch oben im Tal" SONGWRITER "Gabi Geil" REM no pregap INDEX 01 02:45:38 TRACK 03 AUDIO REM pregap with zero data PREGAP 00:4:47 INDEX 01 07:58:74 REM postgap with zero data POSTGAP 00:35:00 Since cdrdao cannot decode the MP3 file on the fly this step must be carried out by hand, e.g. using lame: lame --decode uwe.froehn.mp3 uwe.froehn.wav Although the filename appears only once in the example CUE file it gets written for every track in the TOC file so you would need to edit lots of occurences of the filename in the TOC file by hand. For this reason you can specify a string with the -w option to be used by cue2toc as the filename for all audio tracks. The command cue2toc -w uwe.froehn.wav -o uwe.froehn.toc uwe.froehn.cue should produce the file uwe.froehn.toc with the following content: CATALOG "1234567890123" CD_DA CD_TEXT { LANGUAGE_MAP { 0 : EN } LANGUAGE 0 { TITLE "Der Berg ruft" PERFORMER "Uwe Froehn" } } TRACK AUDIO CD_TEXT { LANGUAGE 0 { TITLE "Meine Mama ist die Beste" PERFORMER "Uwe Froehn" SONGWRITER "Hansi Klabuster" } } AUDIOFILE "uwe.froehn.wav" 00:00:00 02:45:38 START 00:02:00 INDEX 00:35:17 INDEX 01:12:44 TRACK AUDIO CD_TEXT { LANGUAGE 0 { TITLE "Hoch oben im Tal" SONGWRITER "Gabi Geil" } } AUDIOFILE "uwe.froehn.wav" 02:45:38 05:13:36 TRACK AUDIO PREGAP 00:04:47 AUDIOFILE "uwe.froehn.wav" 07:58:74 SILENCE 00:35:00 SEE ALSO

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>. AUTHOR
