       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

       -auxdevice auxdevice
	      uses auxdevice as CDROM drive for ioctl usage.

       -I interface

       -interface interface
	      specifies	 the  interface	 for CDROM access: generic_scsi or (on
	      Linux, and FreeBSD systems) cooked_ioctl.

       -c channels  --channels
	      uses 1 for mono, or 2 for stereo	recording,  or	s  for	stereo
	      recording with both channels swapped.

       -s  --stereo
	      sets to stereo recording.

       -m  --mono
	      sets to mono recording.

       -x  --max
	      sets maximum (CD) quality.

       -b bits	--bits-per-sample
	      sets bits per sample per channel: 8, 12 or 16.

       -r rate	--rate
	      sets  rate  in  samples  per second.  Possible values are listed
	      with the -R option.

       -a divider  --divider
	      sets rate to 44100Hz / divider.  Possible values are listed with
	      the -R option.

       -R  --dump-rates
	      shows a list of all sample rates and their dividers.

       -P  sectors  --set-overlap
	      sets  the	 initial  number of overlap sectors for jitter correc‐

       -n sectors  --sectors-per-request
	      reads sectors per request.

       -l buffers  --buffers-in-ring
	      uses a ring buffer with buffers total.

       -t track+endtrack  --track
	      selects the start track and optionally the end track.

       -i index	 --index
	      selects the start index.

       -o offset  --offset
	      starts offset sectors behind start track (one sector equivalents
	      1/75 seconds).

       -O  audiotype  --output-format
	      can be wav (for wav files) or aiff (for apple/sgi aiff files) or
	      aifc (for apple/sgi aifc files) or au or sun (for	 sun  .au  PCM
	      files)  or  cdr  or  raw (for headerless files to be used for cd

       -C endianess  --cdrom-endianess
	      sets endianess of	 the  input  samples  to  'little',  'big'  or
	      'guess' to override defaults.

       -E endianess  --output-endianess
	      sets  endianess  of  the	output samples to 'little' or 'big' to
	      override defaults.

       -d duration  --duration
	      sets recording time in seconds or frames.	 Frames (sectors)  are
	      indicated by a 'f' suffix (like 75f for 75 sectors).  0 sets the
	      time for whole track.

	      changes pitch of audio data copied to sound device.

       -v  itemlist  --verbose-level
	      prints verbose information about the CD.	Level  is  a  list  of
	      comma  seperated suboptions. Each suboption controls the type of
	      information to be reported.

	      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

       -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.

	      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							  │
   │	   0 │ no errors encountered, successful operation.			  │

       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	begin‐
	      ning  of a track so you can pick exactly the part you want. Each
	      sector runs for 1/75 seconds, so you have very fine control.  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 pas‐
	      sages 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'.

	      -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).

       Thanks goto Project MODE ( and Fraunhofer Institut
       fuer integrierte	 Schaltungen  (FhG-IIS)	 (  for
       financial  support.  Plextor Europe and Ricoh Japan provided cdrom disk
       drives and cd burners which helped a  lot  to  develop  this  software.
       Rammi  has  helped a lot with the debugging and showed a lot of stamina
       when hearing 100 times the first 16 seconds of the first track  of  the
