       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  --dev --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).  The setting of the envi-
	      ronment variable CDDA_DEVICE is overridden by this option.

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

       -I 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.

       -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

       -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 head-
	      erless files to be used for cd writers).

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

       -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.

       -B  --bulk --alltracks
	      copies each track into a seperate file.

       -N  --no-write
	      does not write to a file, it just reads (for debugging purposes).

       -J  --info-only
	      does not write to a file, it just gives information about the disc.

       -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 handled.

	      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 reading.

       -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.

	      use the paranoia library instead of cdda2wav's routines for reading.

       -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  compatible  with  Jorg
       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 connection will not be cre-
	      ated 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.

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

	    |Exitcode | Description							   |
	    |	    0 | no errors encountered, successful operation.			   |
	    |	    1 | usage or syntax error. cdda2wav got inconsistent arguments.	   |
	    |	    2 | permission (un)set errors. permission changes failed.		   |
	    |	    3 | read errors on the cdrom/burner device encountered.		   |
	    |	    4 | write errors while writing one of the output files encountered.    |
	    |	    5 | errors with soundcard handling (initialization/write).		   |
	    |	    6 | errors with stat() system call on the read device (cooked ioctl).  |
	    |	    7 | pipe communication errors encountered (in forked mode). 	   |
	    |	    8 | signal handler installation errors encountered. 		   |
	    |	    9 | allocation of shared memory failed (in forked mode).		   |
	    |	   10 | dynamic heap memory allocation failed.				   |
	    |	   11 | errors on the audio cd medium encountered.			   |
	    |	   12 | device open error in ioctl handling detected.			   |
	    |	   13 | race condition in ioctl interface handling detected.		   |
	    |	   14 | error in ioctl() operation encountered. 			   |
	    |	   15 | internal error encountered. Please report back!!!		   |
	    |	   16 | error in semaphore operation encountered (install / request).	   |
	    |	   17 | could not get the scsi transfer buffer. 			   |
	    |	   18 | could not create pipes for process communication (in forked mode). |
       cdda2wav is able to read parts of an audio CD or multimedia CDROM (containing 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 Windows).	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 available 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  follow-
	      ing text all of them are described.

       Select Device
	      -D  device  selects  the CDROM drive device to be used.  The specifier 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 recordings 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 capa-
	      ble of playing 12-bit or 16-bit samples). Selecting 12  or  16  bits  doubles  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 minimally 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 fre-
	      quencies. 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  (limited by the optional end track or otherwise depending on recording time).
	      Whether one file or different files are then created depends on the -B option  (see

       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 additionally (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

	      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 nei-
	      ther 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  (signal

       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

       Wait for signal option
	      -w Turning on this option will suppress all silent output at startup, reducing pos-
	      sibly 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 sam-
	      ple value found during recording for both channels. This can be  useful  for  read-
	      justing  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 setting 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 modulation (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  exten-
	      sion 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 writers. Since there is no header information in this for-
	      mat, 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 setting,  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  set-
	      tings of the output format.

       Verbose option
	      -v  itemlist prints more information. A list allows selection of different informa-
	      tion 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 notation

	      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 displays track number and track time for each entry.	The  sum-
	      mary 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-permitted 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

       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 Jorg Schilling.
	      I will not describe it here.

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

       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.

       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 switching 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 sectors 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 byteorder).

       If you want to sample more than one track into different files in one run,  this  is  cur-
       rently 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  gen-
       erated  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 verba-
       tim.  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 information,  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

       IMPORTANT:  it  is prohibited to sell copies of copyrighted material by noncopyright hold-
       ers. This program may not be used to circumvent copyrights.  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 (http://www.mode.net/) and Fraunhofer Institut fur integrierte
       Schaltungen (FhG-IIS) (http://www.iis.fhg.de/) 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 Krupps CD.  Libparanoia
