       cdda2wav  can retrieve audio tracks from CDROM drives (see README for a
       list of drives) that are capable of reading audio data digitally to the
       host (CDDA).



       -D device

       -device device
              uses  device  as  the  source  for  CDDA  reading.   For example
              /dev/cdrom for the cooked_ioctl interface and Bus,ID,Lun for the
              generic_scsi  interface.  The  device has to correspond with the
              interface setting (see below).

              Using the cooked_ioctl is not recommended as this makes cdda2wav
              mainly  depend  on the audio extraction quality of the operating
              system which is usually extremely bad.

              The setting of the environment variable CDDA_DEVICE is  overrid-
              den by this option.

       -A auxdevice

       -L  cddb mode --cddb
              does a cddbp album- and track title lookup based on the cddb id.
              The  parameter  cddb  mode defines how multiple entries shall be

           |Parameter | Description                                               |
           |        0 | interactive mode. The user selects the entry to use.      |
           |        1 | first fit mode. The first entry is taken unconditionally. |
              sets the server to be contacted for title lookups.

              sets the port number to be used for title lookups.

       -H  --no-infofile
              does not write an info file and a cddb file.

       -g  --gui
              formats the output to be better parsable by gui frontends.

       -M  count --md5
              enables calculation of MD-5 checksum for ’count’  bytes  from  a
              beginning of a track.

       -S  speed --speed
              sets  the cdrom device to one of the selectable speeds for read-

       -q  --quiet
              quiet operation, no screen output.

       -V  --verbose-SCSI
              enable SCSI command logging to the console. This is mainly  used
              for debugging.

       -Q  --silent-SCSI
              suppress  SCSI  command  error  reports  to the console. This is
              mainly used for guis.

              Scan all SCSI devices on all SCSI busses and print  the  inquiry
              strings.  This  option  may  be used to find SCSI address of the
              CD/DVD-Recorder on a system.  The numbers printed out as  labels
              are computed by: bus * 100 + target

              use  the  paranoia  library  instead  of cdda2wav’s routines for

       -h  --help
              display version of cdda2wav on standard output.

       Defaults depend on the
              Makefile   and   environment   variable   settings    (currently
              CDDA_DEVICE ).


       CDDA_DEVICE  is  used to set the device name. The device naming is com-
       patible with Joerg Schilling’s cdrecord package.

              is used for cddbp title lookups when supplied.

       RSH    If the RSH environment variable is present, the  remote  connec-
              tion  will not be created via rcmd(3) but by calling the program
              pointed to by RSH.   Use  e.g.   RSH=/usr/bin/ssh  to  create  a
              secure shell connection.

              Note  that  this  forces cdda2wav to create a pipe to the rsh(1)
              program and disallows cdda2wav to directly  access  the  network
              socket to the remote server.  This makes it impossible to set up
              performance parameters and slows down the connection compared to
              a root initiated rcmd(3) connection.

       RSCSI  If  the  RSCSI  environment variable is present, the remote SCSI
              server will not be the program  /opt/schily/sbin/rscsi  but  the
              program  pointed  to by RSCSI.  Note that the remote SCSI server
              program name will be ignored if you log in using an account that
              has  been  created  with  a  remote SCSI server program as login


       cdda2wav uses the following exit codes to indicate various  degress  of

   |Exitcode | Description                                                        |

       cdda2wav is able to read parts of an audio CD or multimedia CDROM (con-
       taining audio parts) directly digitally. These parts can be written  to
       a file, a pipe, or to a sound device.

       cdda2wav  stands  for  CDDA  to WAV (where CDDA stands for compact disc
       digital audio and WAV is a sound sample format introduced  by  MS  Win-
       dows).   It  allows copying CDDA audio data from the CDROM drive into a
       file in WAV or other formats.

       The latest versions try to get higher real-time  scheduling  priorities
       to ensure smooth (uninterrupted) operation. These priorities are avail-
       able for super users and are higher than those of  ’normal’  processes.
       Thus delays are minimized.

       If  your  CDROM is on device DEV and it is loaded with an audio CD, you
       may simply invoke cdda2wav dev=DEV and it will create  the  sound  file
       audio.wav recording the whole track beginning with track 1 in stereo at
       16 bit at 44100 Hz sample rate, if your file system  has  enough  space
       free.   Otherwise recording time will be limited. For details see files


              Most of the options are used to control the format  of  the  WAV
              file. In the following text all of them are described.

       Select Device
              -D device selects the CDROM drive device to be used.  The speci-
              fier given should correspond  to  the  selected  interface  (see
              below).   CHANGE!   For  the  cooked_ioctl interface this is the
              cdrom device descriptor as before.  The SCSI devices  used  with
              the  generic SCSI interface however are now addressed with their
              SCSI-Bus, SCSI-Id, and SCSI-Lun  instead  of  the  generic  SCSI
              device  descriptor!!!  One example for a SCSI CDROM drive on bus
              0 with SCSI ID 3 and lun 0 is -D0,3,0.

       Select Auxiliary device
              -A auxdevice is necessary for CD-Extra handling.  For  Non-SCSI-
              CDROM drives this is the same device as given by -D (see above).
              For SCSI-CDROM drives it is the CDROM drive (SCSI) device  (i.e.
              /dev/sr0  )  corresponding to the SCSI device (i.e.  0,3,0 ). It
              has to match the device used for sampling.

       Select Interface
              -I interface selects the CDROM drive interface. For SCSI  drives
              use  generic_scsi (cooked_ioctl may not yet be available for all
              devices): generic_scsi and cooked_ioctl.   The  first  uses  the
              generic  SCSI  interface, the latter uses the ioctl of the CDROM
              driver. The latter variant works only  when  the  kernel  driver
              supports  CDDA  reading.  This  entry  has to match the selected
              CDROM device (see above).

       Enable echo to soundcard
              -e copies audio data to the sound card while recording,  so  you
              hear  it nearly simultaneously. The soundcard gets the same data
              that is recorded. This is time critical, so it works  best  with
              the  -q  option.   To use cdda2wav as a pseudo CD player without
              recording in a file you could use cdda2wav -q -e -t2 -d0  -N  to
              play  the whole second track. This feature reduces the recording
              speed to at most onefold speed. You cannot make  better  record-
              ings  than  your  sound  card  can  play (since the same data is

       Change pitch of echoed audio
              -p percentage changes the pitch of all audio echoed to  a  sound
              card.  Only  the copy to the soundcard is affected, the recorded
              audio samples in a file remain the same.  Normal pitch, which is
              the  default, is given by 100%.  Lower percentages correspond to
              lower pitches, i.e.  -p  50  transposes  the  audio  output  one
              octave lower.  See also the script pitchplay as an example. This
              option was contributed by Raul Sobon.

       Select mono or stereo recording
              -m or -c 1 selects mono  recording  (both  stereo  channels  are
              mixed), -s or -c 2 or -c s selects stereo recording. Parameter s
              will swap both sound channels.

       Select maximum quality
              -x will set stereo, 16 bits per sample  at  44.1  KHz  (full  CD
              quality).  Note that other format options given later can change
              this setting.

       Select sample quality
              -b 8 specifies 8 bit (1 Byte) for each sample in  each  channel;
              -b 12 specifies 12 bit (2 Byte) for each sample in each channel;
              -b 16 specifies 16 bit (2 Byte) for each sample in each  channel
              (Ensure  that  your  sample  player  or sound card is capable of
              playing 12-bit or 16-bit samples). Selecting 12 or 16 bits  dou-
              bles  file  size.  12-bit samples are aligned to 16-bit samples,
              so they waste some disk space.

       Select sample rate
              -r samplerate selects a sample rate.  samplerate  can  be  in  a
              range  between  44100  and  900.  Option  -R lists all available

       Select sample rate divider
              -a divider selects a sample rate divider.  divider can be  mini-
              mally  1  and  maximally 50.5 and everything between in steps of
              0.5.  Option -R lists all available rates.

              To make the sound smoother at  lower  sampling  rates,  cdda2wav
              sums  over  n samples (where n is the specific dividend). So for
              22050 Hertz output we have to sum over 2 samples, for 900  Hertz
              we  have  to  sum over 49 samples.  This cancels higher frequen-
              cies. Standard sector size of an audio CD  (ignoring  additional
              information)  is  2352  Bytes. In order to finish summing for an
              output sample at sector boundaries the rates above  have  to  be
              choosen.  Arbitrary sampling rates in high quality would require
              some interpolation scheme, which needs much  more  sophisticated

       List a table of all sampling rates
              -R shows a list of all sample rates and their dividers. Dividers
              can range from 1 to 50.5 in steps of 0.5.

       Select start track and optionally end track
              -t n+m selects n as the start track and optionally m as the last
              track  of a range to be recorded.  These tracks must be from the
              table of contents.  This sets the track where recording  begins.
              Recording can advance through the following tracks as well (lim-
              ited by the optional end track or otherwise depending on record-
              ing  time). Whether one file or different files are then created
              depends on the -B option (see below).

       Select start index
              -i n selects the index to start recording with.   Indices  other
              than  1 will invoke the index scanner, which will take some time
              to find the correct start position. An offset may be given addi-
              tionally (see below).

       Set recording time
              -d  n sets recording time to n seconds or set recording time for
              whole track if n is zero. In order to specify  the  duration  in
              frames  (sectors)  also,  the argument can have an appended ’f’.
              Then the numerical argument is to be taken as  frames  (sectors)
              rather than seconds.  Please note that if track ranges are being
              used they define the recording time as well thus overriding  any
              -d option specified times.

              Recording  time is defined as the time the generated sample will
              play (at the defined sample rate). Since  it’s  related  to  the
              amount  of  generated samples, it’s not the time of the sampling
              process itself (which  can  be  less  or  more).   It’s  neither
              strictly  coupled  with  the  time  information  on the audio CD
              (shown by your hifi CD player).  Differences can  occur  by  the
              usage  of  the -o option (see below). Notice that recording time
              will be shortened, unless enough disk  space  exists.  Recording
              can  be aborted at anytime by pressing the break character (sig-
              nal SIGQUIT).

       Record all tracks of a complete audio CD in seperate files
              -B copies each track into a seperate file. A base  name  can  be
              given. File names have an appended track number and an extension
              corresponding to the audio format. To record all audio tracks of
              a CD, use a sufficient high duration (i.e. -d99999).

       Set start sector offset
              -o  sectors increments start sector of the track by sectors.  By
              this option you are  able  to  skip  a  certain  amount  at  the
              beginning  of a track so you can pick exactly the part you want.
              Each sector runs for 1/75 seconds, so you have  very  fine  con-
              trol.  If  your offset is so high that it would not fit into the
              current track, a warning message is issued  and  the  offset  is
              ignored.   Recording time is not reduced.  (To skip introductory
              quiet passages automagically, use the -w option see below.)

       Wait for signal option
              -w Turning on this option will suppress  all  silent  output  at
              startup,  reducing  possibly file size.  cdda2wav will watch for
              any signal in the output signal and switches on writing to file.

       Find extrem samples
              -F Turning on this option will display the most negative and the
              most positive sample value found during recording for both chan-
              nels.  This can be useful for readjusting the volume. The values
              shown are not reset at track boundaries, they cover the complete
              sampling  process.  They are taken from the original samples and
              have the same format (i.e. they are independent of the  selected
              output format).

       Find if input samples are in mono
              -G If this option is given, input samples for both channels will
              be compared. At the end of the program the  result  is  printed.
              Differences in the channels indicate stereo, otherwise when both
              channels are equal it will indicate mono.

       Undo the pre-emphasis in the input samples
              -T Some older audio CDs are recorded with a  modified  frequency
              response  called pre-emphasis. This is found mostly in classical
              recordings. The correction can be seen in the flags of the Table
              Of Contents often. But there are recordings, that show this set-
              ting only in the subchannels. If this option is given, the index
              scanner  will  be  started, which reads the q-subchannel of each
              track. If pre-emphasis is indicated in  the  q-subchannel  of  a
              track,  but  not  in the TOC, pre-emphasis will be assumed to be
              present, and subsequently a reverse filtering is done  for  this
              track before the samples are written into the audio file.

       Set audio format
              -O   audiotype  can be wav (for wav files) or au or sun (for sun
              PCM files) or cdr or raw (for headerless files to be used for cd
              writers).  All file samples are coded in linear pulse code modu-
              lation (as done in the audio compact disc  format).  This  holds
              for  all  audio  formats.   Wav  files are compatible to Wind*ws
              sound files, they have lsb,msb byte order as being used  on  the
              audio  cd.  The  default filename extension is ’.wav’.  Sun type
              files are not like the older common  logarithmically  coded  .au
              files,  but  instead  as mentioned above linear PCM is used. The
              byte order is msb,lsb to be  compatible.  The  default  filename
              extension  is  ’.au’.   The AIFF and the newer variant AIFC from
              the Apple/SGI world store  their  samples  in  bigendian  format
              (msb,lsb).  In AIFC no compression is used.  Finally the easiest
              ’format’, the cdr aka raw format. It  is  done  per  default  in
              msb,lsb  byte order to satisfy the order wanted by most cd writ-
              ers. Since there is no header information in  this  format,  the
              sample  parameters can only be identified by playing the samples
              on a soundcard or similiar. The default  filename  extension  is
              ’.cdr’ or ’.raw’.

       Select cdrom drive reading speed
              -S  speed allows to switch the cdrom drive to a certain level of
              speed in order to reduce read errors. The argument is transfered
              verbatim  to  the  drive.  Details depend very much on the cdrom
              drives.  An argument of 0 for example is often the default speed
              of the drive, a value of 1 often selects single speed.

       Enable MD5 checksums
              -M  count enables calculation of MD-5 checksum for ’count’ bytes
              from the beginning of a track. This  was  introduced  for  quick
              comparisons of tracks.

       Use Monty’s libparanoia for reading of sectors
              -paranoia  selects an alternate way of extracting audio sectors.
              Monty’s library is used with the following default options:


              for details see Monty’s libparanoia documentation.  In this case
              the option -P has no effect.

       Do linear or overlapping reading of sectors
              (This  applies  unless  option  -paranoia is used.)  -P  sectors
              sets the given number of sectors for  initial  overlap  sampling
              for  jitter  correction.  Two cases are to be distinguished. For
              nonzero values, some sectors are read twice to enable cdda2wav’s
              jitter  correction.  If an argument of zero is given, no overlap
              sampling will be used.  For  nonzero  overlap  sectors  cdda2wav
              dynamically adjusts the setting during sampling (like cdparanoia
              does).  If no match can be found, cdda2wav retries the read with
              an increased overlap.  If the amount of jitter is lower than the
              current overlapped samples, cdda2wav reduces  the  overlap  set-
              ting,  resulting  in a higher reading speed.  The argument given
              has to be lower than the total number  of  sectors  per  request
              (see  option  -n  below).   Cdda2wav will check this setting and
              issues a error message otherwise.  The case of zero  sectors  is
              nice  on low load situations or errorfree (perfect) cdrom drives
              and perfect (not scratched) audio cds.

       Set the transfer size
              -n  sectors will set the transfer size to the specified  sectors
              per request.

       Set number of ring buffer elements
              -l   buffers  will  allocate the specified number of ring buffer

       Set endianess of input samples
              -C  endianess will override the default settings  of  the  input
              format.  Endianess can be set explicitly to "little" or "big" or
              to the  automatic  endianess  detection  based  on  voting  with

       Set endianess of output samples
              -E  endianess (endianess can be "little" or "big") will override
              the default settings of the output format.

       Verbose option
              -v  itemlist prints more information. A list allows selection of
              different information items.

              disable keeps quiet

              toc displays the table of contents

              summary displays a summary of recording parameters

              indices  invokes  the index scanner and displays start positions
              of indices

              catalog retrieves and displays a media catalog number

              trackid retrieves and displays international standard  recording

              sectors  displays track start positions in absolute sector nota-

              To combine several requests just list the  suboptions  seperated
              with commas.

       The table of contents
              The  display  will  show  the  table  of contents with number of
              tracks and total time (displayed in mm:ss.hh format, mm=minutes,
              ss=seconds,  hh=rounded 1/100 seconds).  The following list dis-
              plays track number and track time for each entry.   The  summary
              gives a line per track describing the type of the track.

                      track preemphasis copypermitted tracktype chans

              The  track  column holds the track number.  preemphasis shows if
              that track has been  given  a  non  linear  frequency  response.
              NOTE: You can undo this effect with the -T option.  copy-permit-
              ted indicates if this track is allowed to copy.   tracktype  can
              be  data  or  audio. On multimedia CDs (except hidden track CDs)
              both of them should be present.  channels is defined  for  audio
              tracks only. There can be two or four channels.

       No file output
              -N this debugging option switches off writing to a file.

       No infofile generation
              -H  this option switches off creation of an info file and a cddb

       Generation of simple output for gui frontends
              -g this option switches on  simple  line  formatting,  which  is
              needed to support gui frontends (like xcd-roast).

       Verbose SCSI logging
              -V  this  option switches on logging of SCSI commands. This will
              produce a lot of output (when  SCSI  devices  are  being  used).
              This is needed for debugging purposes. The format is the same as
              being used with the cdrecord program from  Joerg  Schilling.   I
              will not describe it here.

       Quiet option
              -q  suppresses  all  screen  output except error messages.  That
              reduces cpu time resources.

       Just show information option
              -J does not write a file, it only prints information  about  the
              disc  (depending on the -v option). This is just for information

CDDBP support

       Lookup album and track titles option
              -L  cddbp mode Cdda2wav tries to retrieve performer, album-, and
              track  titles  from a cddbp server. The default server right now
              is ’’.  It is planned to have more control over
              the  server  handling later.  The parameter defines how multiple
              entries are handled:

       0        interactive mode, the user chooses one of the entries.

       1        take the first entry without asking.

       Set server for title lookups
              cddbp-server  servername When using -L  or  --cddb,  the  server
              being contacted can be set with this option.

       Set portnumber for title lookups
              cddbp-port   portnumber When using -L or --cddb, the server port
              being contacted can be set with this option.


       Don’t create samples you cannot read. First check  your  sample  player
       software  and sound card hardware. I experienced problems with very low
       sample rates (stereo <= 1575 Hz, mono <= 3675 Hz) when trying  to  play
       them  with  standard  WAV players for sound blaster (maybe they are not
       legal in WAV format). Most CD-Writers insist  on  audio  samples  in  a
       bigendian  format.   Now  cdda2wav supports the -E  endianess option to
       control the endianess of the written samples.

       If your hardware is fast enough to run cdda2wav uninterrupted and  your
       CD drive is one of the ’perfect’ ones, you will gain speed when switch-
       ing all overlap sampling off with the -P  0 option. Further fine tuning
       can  be done with the -n  sectors option. You can specify how much sec-
       tors should be requested in one go.

       Cdda2wav supports pipes now. Use a filename of - to let cdda2wav output
       its samples to standard output.

       Conversion  to  other  sound  formats can be done using the sox program
       package (although the use of sox -x to change the byte order of samples
       should  be  no more necessary; see option -E to change the output byte-

       If you want to sample more than one track into different files  in  one
       run, this is currently possible with the -B option. When recording time
       exceeds the track limit a new file will be opened for the next track.


       Cdda2wav can generate a lot of files for various purposes.

       Audio files:

       There are audio files containing samples with default extensions  These
       files  are  not generated when option (-N) is given. Multiple files may
       be written when the bulk copy option  (-B)  is  used.  Individual  file
       names  can  be given as arguments. If the number of file names given is
       sufficient to cover all included audio tracks, the file names  will  be
       used  verbatim.   Otherwise,  if  there  are less file names than files
       needed to write the included tracks, the part of the file  name  before
       the  extension  is  extended with ’_dd’ where dd represents the current
       track number.

       Cddb and Cdindex files:

       If cdda2wav detects cd-extra or cd-text  (album/track)  title  informa-
       tion,  then .cddb and .cdindex files are generated unless suppressed by
       the option -H. They contain suitable formatted entries  for  submission
       to  audio  cd  track  title  databases in the internet. The CDINDEX and
       CDDB(tm) systems are currently supported. For more  information  please
       visit and

       Inf files:

       The  inf  files  are  describing the sample files and the part from the
       audio cd, it was taken from. They are a means to  transfer  information
       to  a  cd  burning  program like cdrecord. For example, if the original
       audio cd had pre-emphasis enabled, and cdda2wav -T did remove the  pre-
       emphasis,  then  the inf file has pre-emphasis not set (since the audio
       file does not have it anymore), while the .cddb and the  .cdindex  have
       pre-emphasis set as the original does.


       IMPORTANT:  it  is prohibited to sell copies of copyrighted material by
       noncopyright holders. This program may not be used to circumvent  copy-
       rights.  The user acknowledges this constraint when using the software.


       Generation of md5 checksums is currently broken.

       Performance may not be optimal on slower systems.

       The index scanner may give timeouts.

       The resampling (rate conversion code)  uses  polynomial  interpolation,
       which is not optimal.

       Cdda2wav should use threads.

       Cdda2wav currently cannot sample hidden audio tracks (track 1 index 0).
