DESCRIPTION
       icedax  stands  for InCrEdible Digital Audio eXtractor. It can retrieve
       audio tracks (CDDA) from	CDROM drives that are capable of reading audio
       data digitally to the host (see README for a list of drives).

OPTIONS
       dev=device

       -D device

       -device device
	      uses  device  as	the  source  for  CDDA	reading.  For  example
	      /dev/cdrom or Bus,ID,Lun.	 The  device  specification  can  also
	      have  influence on the selection of the driver interface (eg. on
	      Linux).  See the -I option for details.

	      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.

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

       -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-
	      tion.

       -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
	      writers).

       -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 separate	file.

       -w  --wait
	      waits for	signal,	then start recording.

       -F  --find-extremes
	      finds extreme amplitudes in samples.

       -G  --find-mono
	      finds if input samples are in mono.

       -T  --deemphasize
	      undo the effect of pre-emphasis in the input samples.

       -e  --echo
	      copies audio data	to sound device	e.g.  /dev/dsp.

       -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  separated suboptions. Each	suboption controls the type of
	      information to be	reported.

	      |		 | (when available)				     |
	      +----------+---------------------------------------------------+
       -N  --no-write
	      does  not	 write	to  a  file, it	just reads (for	debugging pur-
	      poses).

       -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.

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

	cddbp-port=portnumber
	      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-
	      ing.

       -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.

       -scanbus
	      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

       --devices
	      Like -scanbus but	works in a more	native way, respecting the de-
	      vice  name  specification	 on  the current operating system. See
	      wodim(1) for details.

       -paranoia
	      use the paranoia library instead of icedax's routines for	 read-
	      ing.

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

       Defaults	depend on the
	      Makefile	and  environment variable settings (currently CDDA_DE-
	      VICE ).

ENVIRONMENT VARIABLES
       CDDA_DEVICE is used to set the device name. The device naming  is  com-
       patible with the	one used by the	wodim tool.

       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 se-
	      cure shell connection.

	      Note that	this forces icedax to create a pipe to the rsh(1) pro-
	      gram  and	disallows icedax to directly access the	network	socket
	      to the remote server.  This makes	it impossible to set  up  per-
	      formance	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.

       icedax  uses  the  following  exit codes	to indicate various degrees of
       success:

DISCUSSION
       icedax 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.

       icedax stands for CDDA to WAV (where CDDA stands	for compact disc digi-
       tal  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	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 icedax dev=DEV and it	will create the	sound file au-
       dio.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 be-
	      low).  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 de-
	      vice 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 icedax as	a  pseudo  CD  player  without
	      recording	 in  a	file  you could	use icedax -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 oc-
	      tave 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, icedax 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  frequencies.
	      Standard	sector size of an audio	CD (ignoring additional	infor-
	      mation) is 2352 Bytes. In	order to finish	summing	for an	output
	      sample  at  sector boundaries the	rates above have to be chosen.
	      Arbitrary	sampling rates in high quality would require some  in-
	      terpolation scheme, which	needs much more	sophisticated program-
	      ming.

       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).
		 .IP  "Record  all  tracks  of a complete audio	CD in separate
	      files" -B	copies each track into a separate 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.  icedax will watch for any
	      signal in	the output signal and switches on writing to file.

       Find extreme 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 ex-
	      tension 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  similar. 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 icedax's
	      jitter correction.  If an	argument of zero is given, no  overlap
	      sampling	will  be used.	For nonzero overlap sectors icedax dy-
	      namically	adjusts	the setting during sampling  (like  cdparanoia
	      does).   If  no match can	be found, icedax retries the read with
	      an increased overlap.  If	the amount of jitter is	lower than the
	      current  overlapped samples, icedax 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 op-
	      tion -n below).  Icedax will check this setting and issues a er-
	      ror  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 separated
	      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	or the
	      wodim tool. See there for	details.

       Quiet option
	      -q suppresses all	screen output except error messages.  That re-
	      duces 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 Icedax 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 be-
	      ing 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 bi-
       gendian format.	Now icedax supports the	-E  endianess option  to  con-
       trol the	endianess of the written samples.

       If your hardware	is fast	enough to run icedax 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.

       Icedax supports pipes now. Use a	filename of - to let icedax 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
       Icedax 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  icedax 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 au-
       dio  cd,	it was taken from. They	are a means to transfer	information to
       a cd burning program like wodim.	For example, if	the original audio  cd
       had  pre-emphasis  enabled,  and	icedax -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-empha-
       sis 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.

       Icedax should use threads.

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