       cdrdao  creates  audio  and  data CD-Rs in disk-at-once (DAO) mode driven by a description
       file called toc-file.  In DAO mode it is possible to create non  standard  track  pre-gaps
       that have other lengths than 2 seconds and contain nonzero audio data. This is for example
       useful to divide live recordings into  tracks  where  2  second  gaps  would  be  kind  of

       Instead  of  a  toc-file  a  cue file (used by a famous DOS/Windows mastering tool) may be
       used. See the CUE FILES section for more details.


       The first argument must be one of the following commands:

              Print out a summary about what will be written to the CD-R.

              Prints out short toc-file summary.

              Prints total number of blocks for toc.

              Analyze each track of the inserted CD and create a toc-file that  can  be  used  to
              make a more or less exact copy of the CD.  This command does not read out the audio
              or data tracks, use read-cd for this purpose.

              You can specify a filename for the data file via the --datafile option.

              Copies all tracks of the inserted CD to an image file and creates  a  corresponding
              toc-file.   The  name  of  the  image  file defaults to "data.bin" if no --datafile
              option is given.

              Tries to retrieve title and artist data from a CDDB server for the  CD  represented
              by  the  given toc-file. The retrieved data is added as CD-TEXT data for language 0
              to the toc-file. Existing CD-TEXT data for language 0 will be overwritten.

              Print out all samples that would be written to the CD-R.  Each  line  contains  the
              sample  number  (starting at 0) and the decimal sample value for the left and right
              channel. Useful to check if the byte order of audio files is correct.

              Check if all data can be read from the audio files that are  defined  in  the  toc-
              file.   This  will  also  check  the  communication  with the slave process that is
              responsible for writing the audio data to the CD-recorder. Mainly used for testing.

              Shows information about the inserted CD-R. If the CD-R has an open session it  will
              also  print  the  start of the last and current session which is used by mkisofs to
              create an image for a second or higher session.

       discid Prints out CDDB information.

       msinfo Shows information required for creating  multi  session  disks  with  mkisofs.  The
              output is meant for processing by scripts.

              Shows drive information.

       unlock Tries  to unlock the recorder device after a failed write or simulation run. If you
              cannot eject the CD after a cdrdao run try this command.

       blank  Blanks a CD-RW. The CD-RW is minimally blanked by default. Use option  --blank-mode
              to  select  another  blanking  mode.  Sometimes the blanking speed must be manually
              reduced for a successful blanking operation. Use option --speed to  select  another
              blanking speed.

              Scan for devices.

              Like write but laser stays cold. It is a shortcut for write --simulate.

       write  Write the CD-R according to the specifications in the toc-file.

       copy   Performs  all  steps  to  copy  a  CD.  The device containing the source CD must be
              specified with option --source-device and the recorder device with option --device.
              If only a single device is available the option --source-device must be omitted and
              cdrdao will prompt to insert the CD-R after an image of the source CD was created.

              The image file with name "cddata<pid>.bin" will be created in the  current  working
              directory if no --datafile option is given. The created image will be removed after
              it has been written.

              If option --on-the-fly is given no image file is  created  and  the  data  will  be
              directly piped from the reading device to the CD recorder.


       --device [prot:]bus,id,lun
              Sets  the  SCSI  address  of  the  CD-recorder in form of a bus/id/lun triple, e.g.
              '0,2,0' for the logical unit 0 of SCSI device with ID 2 on bus 0. ATAPI devices can
              be  specified  by  using the prefix 'ATAPI:', e.g. 'ATAPI:0,0,0'. On some systems a
              device node may be specified directly, e.g. '/dev/sg0' on Linux systems. Linux  2.6
              users may also try the newer ATAPI interface with the 'ATA:' prefix.

       --source-device [prot:]bus,id,lun
              Like above but used for the copy command to specify the source device.

       --driver driver-id:option-flags
              Force  usage  of  specified  driver instead of the automatically determined driver.
              Available driver IDs:
              cdd2600, plextor, plextor-scan, generic-mmc, generic-mmc-raw, ricoh-mp6200, yamaha-
              cdr10x, teac-cdr55, sony-cdu920, sony-cdu948, taiyo-yuden, toshiba.
              Specifying  an  illegal  driver  ID  will give a list of available drivers.  Option
              flags may be used to modify the behavior of some drivers. See README for details.

       --source-driver driver-id:option-flags
              Like above but used for the device specified with option --source-device.

       --speed value
              Set the writing speed to value.  Default is the highest possible speed.

       --blank-mode mode
              Sets the blanking mode. Available modes are full and minimal.  Please consider that
              the  data of minimally blanked disks may be easily recovered. Use the full blanking
              mode for completely erasing all data. The default blanking mode is minimal.

       --datafile file
              Used for read-toc, read-cd and copy.  Set the default data file placed in the  toc-
              file  by  read-toc.   Use  "-" to indicate STDIN.  For commands read-cd and copy it
              specifies the name of the created image file.

              Only used for commands read-cd and read-toc.  All data sectors will be  written  as
              2352  byte  blocks including the sector header and L-EC data to the image file. The
              track mode will be set to MODE1_RAW or MODE2_RAW in the created toc-file.

       --read-subchan mode
              Used by commands read-cd, read-toc and copy.  Specifies  the  type  of  sub-channel
              data  that is extracted from the source CD and written to the track image or copied
              to the destination CD.  Mode may be rw for reading packed R-W sub-channel data (de-
              interleaved  and  error  corrected) and rw_raw for reading raw R-W sub-channel data
              (not de-interleaved, not error corrected, L-EC data included in the  track  image).
              If this option is not specified no sub-channel data will be extracted.

              Only   used  for  commands  read-cd  and  read-toc.   If  we  have  MODE2_FORM1  or
              MODE2_FORM2, don't extract it as MODE2_FORM_MIX.  toc-file.

              This option indicates to the commands read-toc and read-cd that the source  CD  was
              written  in TAO mode. It will be assumed that the pre-gap length between all tracks
              (except between two audio tracks) is the standard 150 blocks  plus  the  number  of
              link  blocks  (usually  2). The number of link blocks can be controlled with option

              Use this option only if read-toc or read-cd give error messages in  the  transition
              areas between two tracks. If you use this option with pressed CDs or CDs written in
              DAO mode you will get wrong results.

       --tao-source-adjust link-blocks
              Specifies the number of link blocks for tracks written in TAO mode. This option has
              only an effect if option --tao-source is given.

              Only  used  for  command  read-toc.   This option suppresses the pre-gap length and
              index mark extraction which speeds up the read-toc process. Standard 2 second  pre-
              gaps  (but  no  silence!)  will  be placed into the toc-file. The resulting CD will
              sound like the source CD.  Only  the  CD  player's  display  will  behave  slightly
              different in the transition area between two tracks.

              This option might help, too, if read-toc fails with your drive otherwise.

       --buffers buffer-count
              Specifies the number of buffers that are allocated to avoid buffer under runs.  The
              minimal buffer count is fixed to 10, default is 32 except on  FreeBSD  systems,  on
              which  default  is  20.   Each buffer holds 1 second of audio data so that dividing
              buffer-count by the writing speed gives the maximum time for which reading of audio
              data may be stalled.

              If  this  option  is  given  the session will not be closed after the audio data is
              successfully written. It is possible to append another session on such disks,  e.g.
              to create a CD-EXTRA.

              By  default cdrdao will not allow one to write more data on a medium than specified
              by the current medium. This option allows one to ignore this condition.

              Eject the CD-R after writing or write simulation.

       --swap Swap the byte order of all samples that are send to the CD-recorder.

       --session session-nr
              Used for read-toc and read-cd to specify the session which should be  processed  on
              multi session CDs.

              Indicates  that the tray may be opened before writing without prompting the user to
              reset the disk status after a simulation run.

              Forces the execution of an operation that otherwise would not be performed.

       --paranoia-mode mode
              Sets the correction mode for digital audio extraction.  0:  No  checking,  data  is
              copied  directly  from the drive. 1: Perform overlapped reading to avoid jitter. 2:
              Like 1 but with additional checks of the read  audio  data.  3:  Like  2  but  with
              additional scratch detection and repair.

              The extraction speed reduces from 0 to 3.

              Default is the full paranoia mode (3).

              If  a  CD is copied with command copy this option will cause that the created image
              is not removed after the copy process has finished.

              Perform CD copy on the fly without creating an image file.

              Enables the automatic fetching of CDDB data for use as CD-TEXT  data  for  commands
              copy, read-toc and read-cd.

       --cddb-servers server-list
              Sets  space or ',' separated list of CDDB servers used for command read-cddb or for
              commands where the --with-cddb option is active.   A  server  entry  may  have  the
              following forms:

              Connect to <server>, default cddbp port (888), use cddbp protocol.

              Connect to <server>, port <port>, use cddbp protocol.

              Connect  to  <server>,  default  http  port (80), use http protocol, url: <cgi-bin-

              Connect to <server>, port <port>, use http protocol, url: <cgi-bin-path>.

              Connect to  <proxy-server>,  default  http  port  (80),  use  http  protocol,  url:

              Connect   to   <proxy-server>,   port   <proxy-port>,   use   http  protocol,  url:

              The <cgi-bin-path> is usually "/~cddb/cddb.cgi".

              All servers of the server list will be tried in the given order until a  successful
              connection  can  be  established.  For  http  proxy  servers  the  first successful
              connected http proxy server will be used independent of the ability to  connect  to
              the target http server.


       --cddb-timeout timeout
              Sets the timeout in seconds used for connections to CDDB servers.

       --cddb-directory directory
              Specifies  the  local  CDDB  database  directory where fetched CDDB records will be
              stored. If this option is not given a  fetched  CDDB  record  will  not  be  stored

       --tmpdir directory
              Specifies  the  directory  in  which  to  store  temporary  data files created from
              decoding MP3 and Ogg Vorbis files. By default, "/tmp" is used.

       --keep Upon exit from cdrdao, do not delete temporary WAV files created from MP3  and  Ogg
              Vorbis files.

       --save Saves  some  of  the current options to the settings file "$HOME/.cdrdao" and exit.
              See section ┬┤SETTINGS┬┤ for more details.

       -n     Suppresses the 10 second pause before writing or simulating.

       -v verbose-level
              Sets verbose level. Levels > 2 are debug levels which produce a lot of output.


       The toc-file describes  what  data  is  written  to  the  CD-R  and  allows  control  over
       track/index positions, pre-gaps and sub-channel information. It is a simple text file, use
       your favorite text editor to create it.

       A toc-file contains an optional header and a sequence of  track  specifications.  Comments
       starting with '//' reaching until end of line can be placed anywhere.

       CATALOG "ddddddddddddd"
              Specifies the optional catalog number of the CD. The string must contain exactly 13

       The following flags specify the type of session that will be created. It is used to create
       the  correct CD-TOC format and to check the consistency of the track modes for the desired
       session type. If multiple flags are given the last one will take effect.

       CD_DA  The disc contains only audio tracks.

       CD_ROM The disc contains just mode 1 tracks or mode 1 and audio tracks (mixed mode CD).

              The disc contains mode 2 form 1 or mode 2 form 2 tracks. Audio tracks are  allowed,
              too. This type must be used if multi session disks are created (option --multi).

       CD_TEXT { ... }
              Defines  global  CD-TEXT data like the album title and the used languages.  See the
              CD-TEXT section below for the syntax of the CD-TEXT block contents.

   Track Specification
       TRACK <track-mode> [<sub-channel-mode>]
              Starts a new track, the track number is incremented by 1. The  length  of  a  track
              must  be  at  least  4  seconds.  The block length of the input data depends on the
              <track-mode>: AUDIO: 2352 bytes (588 samples), MODE1: 2048 bytes,  MODE1_RAW:  2352
              bytes,  MODE2:  2336  bytes,  MODE2_FORM1:  2048  bytes,  MODE2_FORM2:  2324 bytes,
              MODE2_FORM_MIX: 2336 bytes including the sub-header, MODE2_RAW:  2352  bytes.   The
              <sub-channel-mode>  is optional. If given it specifies the type of sub-channel data
              for each sector. RW: packed R-W sub-channel data  (96  bytes,  L-EC  data  will  be
              generated if required), RW_RAW: raw R-W sub-channel data (interleaved and L-EC data
              already calculated, 96 bytes). The block length is  increased  by  the  sub-channel
              data  length if a <sub-channel-mode> is specified.  If the input data length is not
              a multiple of the block length  it will be padded with zeros.

       The following flags may follow the track start statement. They are used to set sub-channel
       information  for  the  current  track.  Each  flag is optional. If not given the following
       defaults are used: copy not permitted, no pre emphasis, two channel audio, no ISRC code.

       [ NO ] COPY
              Sets or clears the copy permitted flag.

       [ NO ] PRE_EMPHASIS
              Sets or clears the pre emphasis flag (only for audio tracks).

              Indicates that track contains two channel audio data (only for audio tracks).

              Indicates that track contains four channel audio data (only for audio tracks).

              Sets ISRC code of track (only for audio tracks).
              C: country code (upper case letters or digits)
              O: owner code (upper case letters or digits)
              Y: year (digits)
              S: serial number (digits)

       An optional CD-TEXT block that defines the CD-TEXT data for this track may follow. See the
       CD-TEXT section below for the syntax of the CD-TEXT block contents.

       CD_TEXT { ... }

       At  least  one of the following statements must appear to specify the data for the current
       track. Lengths and start positions may be expressed in samples (1/44100 seconds) for audio
       tracks  or in bytes for data tracks. It is also possible to give the length in blocks with
       the MSF format 'MM:SS:FF' specifying minutes, seconds and frames (0 <=  'FF'  <  75)  .  A
       frame equals one block.

       If more than one statement is used the track will be composed by concatenating the data in
       the specified order.

       SILENCE <length>
              Adds zero audio data of specified length to the current  audio  track.   Useful  to
              create silent pre-gaps.

       ZERO <length>
              Adds  zero  data  to  data tracks. Must be used to define pre- or post-gaps between
              tracks of different mode.

       [ FILE | AUDIOFILE ] "<filename>" <start> [ <length> ]
              Adds the audio data of specified file to the current audio track. It is possible to
              select  a  portion  of  an  audio  file  with <start> and <length> which allows non
              destructive cutting. The first sample of an audio file is addressed with <start>  =
              0.  If <length> is omitted or set to 0 all audio data from <start> until the end of
              file is used.

              Audio files may have raw or WAVE format with 16 bits per sample, 44.1 kHz  sampling
              rate,  stereo.  Raw  files  must have the layout 'MSBLeft LSBLeft MSBRight LSBRight
              ...' (big endian byte order). WAVE files are expected to have  little  endian  byte
              order.  The  option  --swap  reverses  the expected byte order for all raw and WAVE
              files. Only filenames with a ".wav" ending are treated as  WAVE  files,  all  other
              names  are  assumed  to  be raw audio files. Use tools like sox(1) to convert other
              file formats to supported formats.

              Specifying a "-" as filename causes data to be read from STDIN. Currently only  raw
              files are supported from STDIN.

              If  you  are unsure about the byte order of your audio files try the command 'show-
              data'. If the byte order is correct you  will  see  a  sequence  of  increasing  or
              decreasing  numbers  for  both channels. Otherwise numbers are jumping between very
              high and low values - high volume static.

       DATAFILE "<filename>" [ <length> ]
              Adds data from given file to the current data track. If  <length>  is  omitted  the
              actual file length will be used.

       FIFO "<fifo path>" <length>
              Adds  data  from  specified FIFO path to the current audio or data track.  <length>
              must specify the amount of data that will be read  from  the  FIFO.  The  value  is
              always  in  terms  of  bytes  (scalar  value)  or in terms of the block length (MSF

       START [ MM:SS:FF ]
              Defines the length of the pre-gap (position where index switches from 0 to  1).  If
              the  MSF  value  is  omitted the current track length is used. If the current track
              length is not a multiple of the block length the pre-gap length will be rounded  up
              to next block boundary.

              If no START statement is given the track will not have a pre-gap.

              This  is  an alternate way to specify a pre-gap with zero audio data. It may appear
              before the first SILENCE, ZERO or FILE statement. Either PREGAP  or  START  can  be
              used within a track specification. It is equivalent to the sequence
                SILENCE MM:SS:FF
              for audio tracks or
                ZERO MM:SS:FF
              for data tracks.

       Nothing  prevents mixing 'DATAFILE'/'ZERO' and 'AUDIOFILE'/'SILENCE' statements within the
       same track. The results, however, are undefined.

       The end of a track specification may contain zero or more index increment statements:

              Increments the index number at given position within the track. The first statement
              will  increment  from 1 to 2. The position is relative to the real track start, not
              counting an existing pre-gap.

   CD-TEXT Blocks
       A CD-TEXT block may be placed in the global section to define data valid for the whole  CD
       and  in each track specification of a toc-file.  The global section must define a language
       map that is used to map a language-number to country codes. Up to  8  different  languages
       can be defined:

       LANGUAGE_MAP { 0 : c1  1 : c2  ...  7 : c7 }
              The  country  code  may  be  an  integer  value  in  the range 0..255 or one of the
              following countries (the corresponding integer value is placed in braces behind the
              token): EN(9, English)
              It is just necessary to define a mapping for the used languages.

       If no mapping exists for a language-number the data for this language will be ignored.

       For  each  language a language block must exist that defines the actual data for a certain

       LANGUAGE language-number { cd-text-item cd-text-data cd-text-item cd-text-data ... }
              Defines the CD-TEXT items for given language-number which must be  defined  in  the
              language map.

       The cd-text-data may be either a string enclosed by " or binary data like
            { 0, 10, 255, ... }
       where each integer number must be in the range 0..255.
       The cd-text-item may be one of the following:

       TITLE  String data: Title of CD or track.

              String data.

              String data.

              String data.

              String data.

              String data. Message to the user.

              String data: Should only appear in the global CD-TEXT block. The format is usually:

       GENRE  Mixture of binary data (genre code) and string data.  Should  only  appear  in  the
              global CD-TEXT block. Useful entries will be created by gcdmaster.

              Binary data: Optional table of contents 1. Should only appear in the global CD-TEXT

              Binary data: Optional table of contents 2. Should only appear in the global CD-TEXT

              String  data:  This item should only appear in the global CD-TEXT block. Was always
              an empty string on the CD-TEXT CDs I had access to.

       ISRC   String data: ISRC code of track. The format is usually: CC-OOO-YY-SSSSS

              Binary data: Contains summary about all CD-TEXT data and should only appear in  the
              global  CD-TEXT  block. The data will be automatically (re)created when the CD-TEXT
              data is written.

              is  defined  for  at least on track or in the global section it must be defined for
              all tracks and in the global section. If a DISC_ID item is defined  in  the  global
              section, an ISRC entry must be defined for each track.

       Cue  files  may be used wherever a toc-file is expected. The corresponding bin file is not
       taken from the FILE statement of a cue file but constructed from  the  cue  file  name  by
       replacing ".cue" by ".bin". The cue file must have exactly one FILE statement.

       Currently,  following  track  modes  are  supported:  MODE1/2048,  MODE1/2352, MODE2/2336,
       MODE2/2352. The CATALOG, ISRC and POSTGAP statements are parsed but not evaluated, yet.


       Some of the command line options can be stored as settings  at  following  locations.  The
       files will be read on startup of cdrdao in that order:

       1. /etc/cdrdao.conf

       2. /etc/defaults/cdrdao

       3. /etc/default/cdrdao

       4. $HOME/.cdrdao

       Command  line options will overwrite the loaded settings.  The settings file contains name
       - value pairs separated by a colon. String values must be  enclosed  by  ".  The  file  is
       automatically written if the command line option --save is used but it is also possible to
       modify it manually. Following values are defined:

              Device used for operations simulate, write,  copy,  blank,  disk-info  and  unlock.
              Corresponding option: --device

              Driver  (including  driver  options)  that  is used for operations simulate, write,
              copy, blank, disk-info and unlock.  Corresponding option: --driver

              Specifies writing speed. Corresponding option: --speed

              Specifies fifo buffers used for recording. Corresponding option: --buffers

              Device used for operations  read-toc,  read-cd  and  copy.   Corresponding  option:
              --device or --source-device

              Driver  (including  driver options) used for operations read-toc, read-cd and copy.
              Corresponding option: --driver or --source-driver

              Paranoia  mode  used  for  operations  read-cd  and  copy.   Corresponding  option:

              CDDB server list for read-cddb.  Corresponding option: --cddb-servers

              CDDB  connection  timeout  in  seconds  used  by  read-cddb.  Corresponding option:

              Local directory where fetched CDDB records  will  be  stored,  used  by  read-cddb.
              Corresponding option: --cddb-directory

              Directory  where  temporary  WAV  files  will  be created from decoding MP3 and Ogg
              Vorbis files. Corresponding option: --tmpdir


       If the program is terminated during the write/simulation process used  IPC  resources  may
       not be released. Use ipcs(8) and ipcrm(8) to delete them.
