       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.

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

       -p  percentage --set-pitch
	      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.

	|Suboption | Description						    |

	      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.

	      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  /usr/local/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.			  |
   |	   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.				  |

       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'.

       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).

       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
