NAME
       cdparanoia  (Paranoia  release III) - an	audio CD reading utility which
       includes	extra data verification	features

DATE
       version III release alpha 9.8 (02 Mar 2001)

SYNOPSIS
       cdparanoia [options] span [outfile]

DESCRIPTION
       cdparanoia retrieves audio tracks from CDDA capable CDROM 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
       CDROM drive makes are supported;	cdparanoia can determine if the	target
       drive is	CDDA capable.

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

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  CDROM  drive autosense, query and print the CDROM 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	cdparanoia usage and options.

       -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;	cdparanoia will	split the out-
	      put  into	multiple files at track	boundaries.  Output file names
	      are prepended with 'track#.'

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

       -C --force-cdrom-big-endian
	      As above but force cdparanoia 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 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 CDROM drive it finds.  This can be used to spec-
	      ify devices of any valid interface type (ATAPI, SCSI or  propri-
	      etary).

       -g --force-generic-device device
	      This  option  is used along with -d when one wants explicit con-
	      trol in setting both the SCSI cdrom and generic  devices	seper-
	      ately. This option is only useful	on non-standard	SCSI setups.

       -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
	      Use this option to force the entire disc to shift	 sample	 posi-
	      tion output by the given amount; This can	be used	to shift track
	      boundaries for the whole disc manually  on  sample  granularity.
	      Note  that this will cause cdparanoia to attempt to read partial
	      sectors before or	past the known user data  area	of  the	 disc,
	      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, cdparanoia 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.

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

	 :-0  SCSI/ATAPI transport error

	 :-(  Scratch detected

	 ;-(  Gave up trying to	perform	a correction

	 8-X  Aborted read due to known, uncorrectable error

	 :^D  Finished extracting

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	cdparanoia  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:

	      cdparanoia -vsQ

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

	      cdparanoia -B

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

	      cdparanoia "1[:30.12]-1[1:10]"

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

	      cdparanoia -- "-3"

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

OUTPUT
       The output file argument	is optional; if	it is not  specified,  cdpara-
       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
       Cdparanoia 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.
