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
       -A --analyze-drive
	      Run and log a complete analysis of  drive	 caching,  timing  and
	      reading  behavior;  verifies that	cdparanoia is correctly	model-
	      ling a sprcific drive's cache and	read behavior. Implies -vQL.

       -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.

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

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

       -L --log-debug file
	      Save detailed device autosense and debugging output to a 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 en-
	      dian device.

       -C --force-cdrom-big-endian
	      As above but force cd-paranoia to	treat the drive	as a  big  en-
	      dian 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  re-
	      stricted 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 ac-
	      counts 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 us-
	      ing -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,  de-
	      fault 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  be-
	      low will simulate	the kind of specified failure.

	    0x10  - Simulate under-run reading

       OUTPUT SMILIES

	 :-)  Normal operation,	low/no jitter

	 :-|  Normal operation,	considerable jitter

	 :-/  Read drift

	 :-P  Unreported loss of streaming in atomic read operation

	 8-|  Finding  read problems at	same point during reread; hard to cor-
	      rect

PROGRESS BAR SYMBOLS
       <space>
	      No corrections needed

	  -   Jitter correction	required

	  +   Unreported loss of streaming/other error in read

	  !   Errors found after stage 1 correction; the drive is  making  the
	      same  error through multiple re-reads, and cd-paranoia is	having
	      trouble detecting	them.

	  e   SCSI/ATAPI transport error (corrected)

	  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 in-
	      cluding) 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 au-
       tosense:

	      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 de-
       pending	on  whether  -w,  -a, -r or -R is used (-w is the implicit de-
       fault).	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.
