NAME
       cd-paranoia  -  9.8 (Paranoia release III via libcdio) - an audio CD reading 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 target drive is CDDA capable.

       In  addition  to simple reading, cd-paranoia adds extra-robust data verification, synchro-
       nization, 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 reading 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 compatibility.

       -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 val-
	      ues 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  specific 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  output  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 recom-
	      mended.

       -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

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 specification.  The syn-
       tax 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 specified: [::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 offset is taken to be the start or end of the  disc,  respec-
       tively. 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-paranoia will output sam-
       ples 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 out-
       put; 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.
