NAME
       cd-paranoia  9.8 (Paranoia release III via libcdio) - an audio CD read‐
       ing utility which includes extra data verification features

SYNOPSIS
       cd-paranoia [options] span [outfile]

DESCRIPTION
       cd-paranoia retrieves audio tracks from	CDDA  capable  CD-ROM  drives.
       The  data can be saved to a file or directed to standard output in WAV,
       AIFF, AIFF-C or raw format.  Most ATAPI, SCSI and  several  proprietary
       CD-ROM drive makes are supported; cd-paranoia can determine if the tar‐
       get drive is CDDA capable.

       In addition to simple reading, cd-paranoia adds extra-robust data veri‐
       fication,  synchronization,  error  handling and scratch reconstruction
       capability.

       This version uses the libcdio library for  interaction  with  a	CD-ROM
       drive.  The jitter and error correction however are the same as used in
       Xiph's cdparanoia.

OPTIONS
       -v --verbose
	      Be absurdly verbose about the autosensing and  reading  process.
	      Good for setup and debugging.

       -q --quiet
	      Do  not print any progress or error information during the read‐
	      ing process.

       -e --stderr-progress
	      Force output of progress	information  to	 stderr	 (for  wrapper
	      scripts).

       -V --version
	      Print the program version and quit.

       -Q --query
	      Perform CD-ROM drive autosense, query and print the CD-ROM table
	      of contents, then quit.

       -s --search-for-drive
	      Forces a	complete  search  for  a  cdrom	 drive,	 even  if  the
	      /dev/cdrom link exists.

       -h --help
	      Print a brief synopsis of cd-paranoia usage and options.

       -l --log-summary file
	      Save result summary to file.

       -p --output-raw
	      Output  headerless  data as raw 16 bit PCM data with interleaved
	      samples in host byte order.  To force little or big endian  byte
	      order, use -r or -R as described below.

       -r --output-raw-little-endian
	      Output  headerless  data as raw 16 bit PCM data with interleaved
	      samples in LSB first byte order.

       -R --output-raw-big-endian
	      Output headerless data as raw 16 bit PCM data  with  interleaved
	      samples in MSB first byte order.

       -w --output-wav
	      Output  data in Micro$oft RIFF WAV format (note that WAV data is
	      always LSB first byte order).

       -f --output-aiff
	      Output data in Apple AIFF format (note that AIFC data is	always
	      in MSB first byte order).

       -a --output-aifc
	      Output data in uncompressed Apple AIFF-C format (note that AIFF-
	      C data is always in MSB first byte order).

       -B --batch

	      Cdda2wav-style batch output flag;	 cd-paranoia  will  split  the
	      output  into  multiple  files  at track boundaries.  Output file
	      names are prepended with 'track#.'

       -c --force-cdrom-little-endian
	      Some CD-ROM drives misreport their endianness (or do not	report
	      it  at  all);  it's  possible that cd-paranoia will guess wrong.
	      Use -c to force cd-paranoia to  treat  the  drive	 as  a	little
	      endian device.

       -C --force-cdrom-big-endian
	      As  above	 but  force  cd-paranoia  to  treat the drive as a big
	      endian device.

       -n --force-default-sectors n
	      Force the interface backend to do atomic reads of n sectors  per
	      read.   This  number  can	 be  misleading; the kernel will often
	      split read requests into multiple atomic	reads  (the  automated
	      Paranoia	code  is  aware	 of  this) or allow reads only wihin a
	      restricted size range.  This  option  should  generally  not  be
	      used.

       -d --force-cdrom-device device
	      Force  the interface backend to read from device rather than the
	      first readable CD-ROM drive it finds containing  a  CD-DA	 disc.
	      This  can be used to specify devices of any valid interface type
	      (ATAPI, SCSI or proprietary).

       -g --force-generic-device device
	      This option is an alias for -d and is retained  for  compatibil‐
	      ity.

       -S --force-read-speed number
	      Use  this option explicitly to set the read rate of the CD drive
	      (where supported).  This can reduce underruns on	machines  with
	      slow disks, or which are low on memory.

       -t --toc-offset number
	      Use this option to force the entire disc LBA addressing to shift
	      by the given amount; the value is added to the beginning offsets
	      in  the TOC.  This can be used to shift track boundaries for the
	      whole disc manually on sector granularity.  The next option does
	      something similar...

       -T --toc-bias
	      Some  drives  (usually  random Toshibas) report the actual track
	      beginning offset values in the TOC, but then treat the beginning
	      of  track	 1  index 1 as sector 0 for all read operations.  This
	      results in every track seeming to start too late (losing	a  bit
	      of  the  beginning  and  catching	 a bit of the next track).  -T
	      accounts for this behavior.  Note that this  option  will	 cause
	      cd-paranoia  to attempt to read sectors before or past the known
	      user data area of the disc, resulting in	read  errors  at  disc
	      edges  on	 most  drives  and  possibly even hard lockups on some
	      buggy hardware.

       -O --sample-offset number
	      Some CD-ROM/CD-R drives will add an offset to  the  position  on
	      reading audio data. This is usually around 500-700 audio samples
	      (ca. 1/75 second) on reading. So when cd-paranoia queries a spe‐
	      cific  sector,  it  might	 not  receive exactly that sector, but
	      shifted by some amount.

       Use this option to force the entire disc to shift sample position  out‐
       put by the given amount; This can be used to shift track boundaries for
       the whole disc manually on sample granularity. Note  that  if  you  are
       ripping	something  including  the  ending  of  the CD (e.g. the entire
       disk), this option will cause cd-paranoia to attempt  to	 read  partial
       sectors	before or past the known user data area, probably causing read
       errors on most drives and possibly even	hard  lockups  on  some	 buggy
       hardware.

       -Z --disable-paranoia
	      Disable  all  data  verification	and correction features.  When
	      using -Z, cd-paranoia reads data exactly as would cdda2wav  with
	      an  overlap  setting  of	zero.	This option implies that -Y is
	      active.

       -z --never-skip[=max_retries]
	      Do not accept any skips; retry forever if needed.	  An  optional
	      maximum  number  of  retries  can	 be specified; for comparison,
	      default without -z is currently 20.

       -Y --disable-extra-paranoia
	      Disables intra-read data verification; only overlap checking  at
	      read  boundaries	is  performed. It can wedge if errors occur in
	      the attempted overlap area. Not recommended.

       -X --abort-on-skip
	      If the read skips due to imperfect data,	a  scratch,  whatever,
	      abort  reading  this  track.  If output is to a file, delete the
	      partially completed file.

       -x --test-flags mask
	      Simulate CD-reading errors. This is used in regression  testing,
	      but  other uses might be to see how well a CD-ROM performs under
	      (simulated) CD degradation. mask specifies the artificial	 kinds
	      of  errors  to  introduced;  "or"-ing  values from the selection
	      below will simulate the kind of specified failure.

	    0x10  - Simulate under-run reading

	  V   Uncorrected error/skip

SPAN ARGUMENT
       The  span  argument  specifies  which  track,  tracks or subsections of
       tracks to read.	This argument is required.  NOTE: Unless the span is a
       simple number, it's generally a good idea to quote the span argument to
       protect it from the shell.

       The span argument may be a simple track number or an offset/span speci‐
       fication.  The syntax of an offset/span takes the rough form:

       1[ww:xx:yy.zz]-2[aa:bb:cc.dd]

       Here,  1	 and  2	 are  track numbers; the numbers in brackets provide a
       finer grained offset within a particular	 track.	 [aa:bb:cc.dd]	is  in
       hours/minutes/seconds/sectors  format.  Zero  fields need not be speci‐
       fied: [::20], [:20], [20], [20.], etc, would be interpreted  as	twenty
       seconds,	 [10:] would be ten minutes, [.30] would be thirty sectors (75
       sectors per second).

       When only a single offset is supplied, it is interpreted as a  starting
       offset  and ripping will continue to the end of the track.  If a single
       offset is preceeded or followed by a hyphen, the implicit missing  off‐
       set is taken to be the start or end of the disc, respectively. Thus:

       1:[20.35]
	      Specifies	 ripping from track 1, second 20, sector 35 to the end
	      of track 1.

       1:[20.35]-
	      Specifies ripping from 1[20.35] to the end of the disc

       -2     Specifies ripping from the beginning of  the  disc  up  to  (and
	      including) track 2

       -2:[30.35]
	      Specifies ripping from the beginning of the disc up to 2:[30.35]

       2-4    Specifies	 ripping  from	the beginning of track 2 to the end of
	      track 4.

       Again, don't forget to protect square brackets and  preceeding  hyphens
       from the shell.

EXAMPLES
       A few examples, protected from the shell:

       Query  only  with  exhaustive  search for a drive and full reporting of
       autosense:

	      cd-paranoia -vsQ

       Extract an entire disc, putting each track in a seperate file:

	      cd-paranoia -B

       Extract from track 1, time 0:30.12 to 1:10.00:

	      cd-paranoia "1[:30.12]-1[1:10]"

       Extract from the beginning of the disc up to track 3:

	      cd-paranoia -- "-3"

       The "--" above is to distinguish "-3" from an option flag.

OUTPUT
       The output file argument is optional; if it is not specified,  cd-para‐
       noia  will  output  samples  to one of cdda.wav, cdda.aifc, or cdda.raw
       depending on whether -w, -a, -r or -R  is  used	(-w  is	 the  implicit
       default).  The output file argument of - specifies standard output; all
       data formats may be piped.

ACKNOWLEDGEMENTS
       cd-paranoia sprang from and once drew heavily  from  the	 interface  of
       Heiko  Eissfeldt's  (heiko@colossus.escape.de)  'cdda2wav' package. cd-
       paranoia would not have happened without it.

       Joerg Schilling has also contributed SCSI expertise through his generic
       SCSI transport library.
