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 overridden 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 correction.

       -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
	      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 subop-
	      tions. 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 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.

	      +----------+------------------------------------------+
	      |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 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.

       -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 device name specifica-
	      tion on the current operating system. See wodim(1) for details.

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

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

       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 compatible 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 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 icedax to create a pipe to the rsh(1) program  and	disallows
	      icedax  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.

DISCUSSION
       icedax 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.

       icedax 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
       icedax 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 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 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  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,  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  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 chosen.  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
	      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 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
	      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 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
	      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 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
	      below.)

       Wait for signal option
	      -w Turning on this option will suppress all silent output at startup, reducing pos-
	      sibly 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 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 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 dynamically 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 over-
	      lapped 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 option -n below).  Icedax 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 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 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
	      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  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 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 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  icedax  supports	the  -E  endianess option to control 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 stan-
       dard 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.

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  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 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 audio 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-emphasis set as  the  original
       does.

       ers. This program may not be used to circumvent copyrights.  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).
