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 tar-
       get 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
	      output  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  begin-
	      ning  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  granu-
	      larity. 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
       
	      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 spec-
       ification.  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.
