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
	      device.


       -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
	      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 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
	      accounts	for  this  behavior.  Note that this option will cause
	      cdparanoia 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
	      using -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,
	      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.


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
	      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:

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

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