DESCRIPTION
       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

       As  cdda2wav  may  be  directed	to  write the audio data to stdout, it
       writes  all  it's  informational	 output	 to  stderr  by	 default.  See
       out-fd=descriptor option below.	(CDDA).

OPTIONS
       dev=device

       -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.

	      If  no  dev=  option is present, or if the dev= option only con‐
	      tains a transport specifyer but no address,  cdda2wav  tries  to
	      scan  the	 SCSI address space for CD-ROM drives.	If exactly one
	      is found, this is used by default.

       ts=#   Set the maximum transfer size for a single SCSI  command	to  #.
	      The  syntax  for the ts= option is the same as for cdrecord fs=#
	      or sdd bs=#.

	      If no ts= option has been	 specified,  cdda2wav  defaults	 to  a
	      transfer	size  of  3 MB.	 If  libscg gets lower values from the
	      operating system, the value is reduced to the maximum value that
	      is  possible  with  the current operating system.	 Sometimes, it
	      may help to further reduce the transfer size or to  enhance  it,
	      but  note that it may take a long time to find a better value by
	      experimenting with the ts= 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.

       out-fd=descriptor
	      Redirect	informational  output  to the file descriptor named by
	      descriptor.  The parameter  descriptor  specifies	 a  UNIX  file
	      descriptor  number.   Redirecting	 the informational output to a
	      different file descriptor helps gui's and	 other	programs  that
	      call cdda2wav via pipes.

       audio-fd=descriptor
	      In case that the file name for the audio data file is "-", redi‐
	      rect audio output to the file descriptor	named  by  descriptor.
	      The  parameter  descriptor specifies a UNIX file descriptor num‐
	      ber.  Redirecting the audio output to a different file  descrip‐
	      tor helps gui's and other programs that call cdda2wav via pipes.

       -no-fork
	      Do  not  fork  for  extended  buffering. If -no-fork is used and
	      cdda2wav is used to play back audio CDs in  paranoia  mode,  the
	      playback is not always uninterrupted.

	      to -track and -offset.

       -O  audiotype

       -output-format audiotype
	      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
	      writers).

       -C endianess

       -h

       -help  display version of cdda2wav on standard output.

       -version
	      display version and Copyright information.

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

ENVIRONMENT VARIABLES
       CDDA_DEVICE is used to set the device name. The device naming  is  com‐
       patible with Joerg Schilling's cdrecord package.

       CDDBP_SERVER
	      is used for cddbp title lookups when supplied.

       CDDBP_PORT
	      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
	      shell.

RETURN VALUES
       cdda2wav	 uses  the following exit codes to indicate various degress of
       success:

   ┌─────────┬────────────────────────────────────────────────────────────────────┐
   │Exitcode │ Description							  │
   ├─────────┼────────────────────────────────────────────────────────────────────┤

   └─────────┴────────────────────────────────────────────────────────────────────┘
DISCUSSION
       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
       README and README.INSTALL

HINTS ON OPTIONS
       Options
	      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
	      used).

       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
	      rates.

       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
	      programming.

       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'.

       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:

	      PARANOIA_MODE_FULL, but without PARANOIA_MODE_NEVERSKIP

	      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
	      elements.

       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
	      "guess".

       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
	      codes

	      sectors  displays track start positions in absolute sector nota‐
	      tion

	      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
	      file.

       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
	      purposes.

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 'freedb.freedb.org'.  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.

HINTS ON USAGE
       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‐
       order).

       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.

FILES
       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 www.musicbrainz.org and www.freedb.com.

       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.

WARNING
       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.

BUGS
       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).
